• Specifying Android project dependencies (in Eclipse)

  - by Henrik Gustafsson

  I have two Android projects, a 'library project' containing a custom layout, and an 'application project' containing an application which uses the layout. Everything seems to build and execute fine, except that the visual layout editor throws a ClassNotFoundException (which I assume is a bug in the plug-in), but when I try to start to make use of the attributes I defined for the custom layout in the xml, I can no longer build. That is; this works: <?xml version="1.0" encoding="utf-8"?> <se.fnord.android.layout.PredicateLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="asdfasdf" /> </se.fnord.android.layout.PredicateLayout> Whereas this does not: <?xml version="1.0" encoding="utf-8"?> <se.fnord.android.layout.PredicateLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:fnord="http://schemas.android.com/apk/res/se.fnord.android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView fnord:layout_horizontalSpacing="1px" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="asdfasdf" /> </se.fnord.android.layout.PredicateLayout> The build fails with a message from aapt: ERROR No resource identifier found for attribute 'layout_horizontalSpacing' in package 'se.fnord.android' The resource identifier does exist in the R-file and attrs.xml contained the library project, and if I put the layout code and resources directly in the application project everything works fine. The layout_horizontalSpacing attribute (and layout_verticalSpacing) is a custom attribute used in the PredicateLayout.LayoutParam class to specify the distance to the next widget. So far I've tried the standard eclipse ways by specifying project references and build path project dependencies. I was also told to try the tag in the application manifest, which did not help. So, what do I need to do for the references in the xml-file to work? I don't know if it's relevant, but the 'library' manifest looks like this: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="se.fnord.android" android:versionCode="1" android:versionName="1.0.0"> </manifest> The 'application' manifest like this: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="se.fnord.appname" android:versionCode="1" android:versionName="1.0.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".AppName" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> (The 'PredicateLayout', btw, is a cleaned-up version of this).

• custom listview adapter getView method being called multiple times, and in no coherent order

  - by edzillion

  I have a custom list adapter: class ResultsListAdapter extends ArrayAdapter<RecordItem> { in the overridden 'getView' method I do a print to check what position is and whether it is a convertView or not: @Override public View getView(int position, View convertView, ViewGroup parent) { System.out.println("getView " + position + " " + convertView); The output of this (when the list is first displayed, no user input as yet) 04-11 16:24:05.860: INFO/System.out(681): getView 0 null 04-11 16:24:29.020: INFO/System.out(681): getView 1 android.widget.RelativeLayout@43d415d8 04-11 16:25:48.070: INFO/System.out(681): getView 2 android.widget.RelativeLayout@43d415d8 04-11 16:25:49.110: INFO/System.out(681): getView 3 android.widget.RelativeLayout@43d415d8 04-11 16:25:49.710: INFO/System.out(681): getView 0 android.widget.RelativeLayout@43d415d8 04-11 16:25:50.251: INFO/System.out(681): getView 1 null 04-11 16:26:01.300: INFO/System.out(681): getView 2 null 04-11 16:26:02.020: INFO/System.out(681): getView 3 null 04-11 16:28:28.091: INFO/System.out(681): getView 0 null 04-11 16:37:46.180: INFO/System.out(681): getView 1 android.widget.RelativeLayout@43cff8f0 04-11 16:37:47.091: INFO/System.out(681): getView 2 android.widget.RelativeLayout@43cff8f0 04-11 16:37:47.730: INFO/System.out(681): getView 3 android.widget.RelativeLayout@43cff8f0 AFAIK, though I couldn't find it stated explicitly, getView() is only called for visible rows. Since my app starts with four visible rows at least the position numbers cycling from 0-3 makes sense. But the rest is a mess: Why is getview called for each row four times? Where are these convertViews coming from when I haven't scrolled yet? I did a bit of reseach, and without getting a good answer, I did notice that people were associating this issue with layout issues. So in case, here's the layout that contains the list: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="vertical" > <TextView android:id="@+id/pageDetails" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <ListView android:id="@+id/list" android:layout_width="fill_parent" android:layout_height="wrap_content" android:drawSelectorOnTop="false" /> </LinearLayout> and the layout of each individual row: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="108dp" android:padding="4dp"> <ImageView android:id="@+id/thumb" android:layout_width="120dp" android:layout_height="fill_parent" android:layout_alignParentTop="true" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:layout_marginRight="8dp" android:src="@drawable/loading" /> <TextView android:id="@+id/price" android:layout_width="wrap_content" android:layout_height="18dp" android:layout_toRightOf="@id/thumb" android:layout_alignParentBottom="true" android:singleLine="true" /> <TextView android:id="@+id/date" android:layout_width="wrap_content" android:layout_height="18dp" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:paddingRight="4dp" android:singleLine="true" /> <TextView android:id="@+id/title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="17dp" android:layout_toRightOf="@id/thumb" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:paddingRight="4dp" android:layout_alignWithParentIfMissing="true" android:gravity="center" /> Thank you for your time

• android: which view should I use for showing text and image?

  - by Yang

  My app shows a list of items, where each line is an item title with its image asides, the line reserves 70% of space for text and 30% for image. Imagine what iphone app store looks like. Which view/layout combo is recommended for this purpose? I googled and find this article: http://www.curious-creature.org/2009/02/22/android-layout-tricks-1/ Does this view sound good? <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip"> <ImageView android:id="@+id/icon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentTop="true" android:layout_alignParentBottom="true" android:layout_marginRight="6dip" android:src="@drawable/icon" /> <TextView android:id="@+id/secondLine" android:layout_width="fill_parent" android:layout_height="26dip" android:layout_toRightOf="@id/icon" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:singleLine="true" android:ellipsize="marquee" android:text="Simple application that shows how to use RelativeLayout" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_toRightOf="@id/icon" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:layout_above="@id/secondLine" android:layout_alignWithParentIfMissing="true" android:gravity="center_vertical" android:text="My Application" />

• Set width of Button in Android

  - by Mohit Deshpande

  How can I set a fixed width for an Android button? Everytime I try to set a fixed width it fills the current parent (the RelativeView). Here is my XML: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout android:id="@+id/relativelayout" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <EditText android:layout_height="wrap_content" android:editable="false" android:layout_width="fill_parent" android:id="@+id/output"></EditText> <Button android:layout_height="wrap_content" android:id="@+id/Button01" android:layout_below="@id/output" android:text="7" android:layout_width="wrap_content"></Button> <Button android:layout_below="@id/output" android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/Button02" android:layout_toRightOf="@+id/Button01" android:text="8"></Button> <Button android:layout_below="@id/output" android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/Button03" android:layout_toRightOf="@+id/Button02" android:text="9"></Button> </RelativeLayout> How would I give it a FIXED width?

• Android NDK r4 san-angeles problem

  - by Goz

  Hi All, I'm starting to learn the android NDK and I've instantly come up against a problem. I'e built the tool chain (which took a LOT longer than I was expecting!!) and I've compiled the C++ code with no problems and now I'm trying to build the java code. Instantly I come up against a problem. There is a file "main.xml" <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" > <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Hello World, DemoActivity" /> </LinearLayout> and I get the following errors: Description Resource Path Location Type error: Error: String types not allowed (at 'layout_height' with value 'match_parent'). main.xml /DemoActivity/res/layout line 2 Android AAPT Problem error: Error: String types not allowed (at 'layout_height' with value 'match_parent'). main.xml /DemoActivity/res/layout line 2 Android AAPT Problem error: Error: String types not allowed (at 'layout_width' with value 'match_parent'). main.xml /DemoActivity/res/layout line 2 Android AAPT Problem error: Error: String types not allowed (at 'layout_width' with value 'match_parent'). main.xml /DemoActivity/res/layout line 7 Android AAPT Problem error: Error: String types not allowed (at 'layout_width' with value 'match_parent'). main.xml /DemoActivity/res/layout line 7 Android AAPT Problem So I can see the problem lies in the fact that these "match_parent" strings are in there. Anyone know how to fix this?

• Android calculator with button click

  - by rynwtts

  I am trying to calculate a field named lblAnswer by adding values txtA + txtB. I am fairly new to the android development world and would like to know what is the best way of going about this. I have already added the necessarily edit fields to the GUI. I am now working in the java file to try and create the method. This method has been named doCalc. Here is what I have thus far. public void doCalc() { lblAnswer = txtA + txtB; } It has been suggested that I add more code here is the full code. Thank you for that suggestion. Here is the Java File. package com.example.wattsprofessional; import android.app.Activity; import android.os.Bundle; import android.view.Menu; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.activity_main, menu); return true; } public void doCalc() { lblAnswer = txtA + txtB; Double.parseDouble(txtA.getText().toString()); lblAnswer.setText"t } and here is the xml file. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" > <EditText android:id="@+id/txtA" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:layout_marginTop="40dp" android:ems="10" android:hint="Write Here" android:inputType="numberDecimal" > <requestFocus /> </EditText> <EditText android:id="@+id/txtB" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignLeft="@+id/txtA" android:layout_below="@+id/txtA" android:layout_marginTop="32dp" android:ems="10" android:hint="Second Here" android:inputType="numberDecimal" /> <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:text="@string/calculate" android:onClick="doCalc"/> <TextView android:id="@+id/lblAnswer" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/button1" android:layout_centerHorizontal="true" android:layout_marginTop="50dp" android:text="TextView" /> </RelativeLayout>

• ListView items not responding to tap

  - by Justin Williams

  I'm just getting my feet wet with Android and have built a UI that contains a TabHost with three tabs. Each tab is powered by its own Activity. The first Tab contains a listview with a prepopulated set of rows and is built from a custom ArrayAdapter. The problem I'm running into is that none of the ListView rows are tappable. In other words, when I tap on them there is no orange selection. If I use the scroll ball on my Nexus One it will select, but any touch gestures don't seem to be responding. All the UI is being handled using XML files with a main.xml housing the TabHost - LinearLayout - TabWidget/FrameLayout and a nearby_activity.xml file containing my ListView UI <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/android:empty" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/nearby_no_events" /> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1.0" android:choiceMode="multipleChoice" android:divider="#d9d9d9" android:dividerHeight="1px" android:cacheColorHint="#eee" /> </LinearLayout> And the relevant code from my Activity that is set to show in the selected tab. public class NearbyActivity extends ListActivity { private ArrayList<Event> m_events = null; private EventAdapter m_adapter = null; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.nearby_activity); getEvents(); this.m_adapter = new EventAdapter(this, R.layout.eventrow, m_events); setListAdapter(this.m_adapter); } private void getEvents() { m_events = new ArrayList<Event>(); for (int i = 0; i < 100 ; i++) { Event e = new Event(); e.setEventName("Event " + i); e.setVenueName("Staples Center"); e.setStartDate(new Date()); m_events.add(e); } } private class EventAdapter extends ArrayAdapter<Event> { private ArrayList<Event> items; public EventAdapter(Context context, int textViewResourceId, ArrayList<Event> items) { super(context, textViewResourceId, items); this.items = items; } @Override public View getView (int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.eventrow, null); } Event e = items.get(position); if (e != null) { TextView nameText = (TextView)v.findViewById(R.id.eventName); TextView venueNameText = (TextView)v.findViewById(R.id.venueName); if (nameText != null) { nameText.setText(e.getEventName()); } if(venueNameText != null) { venueNameText.setText(e.getVenueName()); } } return v; } } } My listview row's are populated by an XML file as well. <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:orientation="vertical" android:padding="4dip"> <TextView android:id="@+id/eventName" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:inputType="text" android:singleLine="true" android:ellipsize="marquee" android:textSize="18sp" android:textColor="#000" /> <TextView android:id="@+id/venueName" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/eventName" android:layout_alignParentBottom="true" android:layout_marginRight="55dip" android:singleLine="true" android:ellipsize="end" android:scrollHorizontally="true" android:textSize="13sp" android:textColor="#313131" android:layout_alignWithParentIfMissing="true" android:gravity="center_vertical" /> </RelativeLayout> Thanks for any help you can offer.

• "Class ref in pre-verified class resolved to unexpected implementation" when running android tests i

  - by Mike

  I have a module that builds an app called MyApp. I have another that builds some testcases for that app, called MyAppTests. They both build their own APKs, and they both work fine from within my IDE. I'd like to build them using ant so that I can take advantage of continuous integration. Building the app module works fine. I'm having difficulty getting the Test module to compile and run. Using Christopher's tip from a previous question, I used android create test-project -p MyAppTests -m ../MyApp -n MyAppTests to create the necessary build files to build and run my test project. This seems to work great (once I remove an unnecessary test case that it constructed for me and revert my AndroidManifest.xml to the one I was using before it got replaced by android create), but I have two problems. The first problem: The project doesn't compile because it's missing libraries. $ ant run-tests Buildfile: build.xml [setup] Project Target: Google APIs [setup] Vendor: Google Inc.

• Ellipsize not working for textView inside custom listView

  - by aspartame

  Hi, I have a listView with custom objects defined by the xml-layout below. I want the textView with id "info" to be ellipsized on a single line, and I've tried using the attributes android:singleLine="true" android:ellipsize="end" without success. If I set the layout_width to a fixed width like e.g. android:layout_width="100px" the text is truncated fine. But for portability reasons this is not an acceptable solution. Can you spot the problem? <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingBottom="5px" > <TextView android:id="@+id/destination" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="22dp" android:paddingLeft="5px" /> <TextView android:id="@+id/date" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="15dp" android:paddingLeft="5px" /> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/info_table" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingLeft="5px" android:paddingTop="10px" > <TableRow> <TextView android:id="@+id/driver_label" android:gravity="right" android:paddingRight="5px" android:text="@string/driver_label" /> <TextView android:id="@+id/driver" /> </TableRow> <TableRow> <TextView android:id="@+id/passenger_label" android:gravity="right" android:paddingRight="5px" android:text="@string/passenger_label" /> <TextView android:id="@+id/passengers" /> </TableRow> <TableRow> <TextView android:id="@+id/info_label" android:gravity="right" android:paddingRight="5px" android:text="@string/info_label"/> <TextView android:id="@+id/info" android:layout_width="fill_parent" android:singleLine="true" android:ellipsize="end" /> </TableRow> </TableLayout>

• How to ellipsize center-aligned textview beside a right-aligned button when screen width is small

  - by simplymoody

  ------------------------------------ | LONG_TITL... |button| | |------------------------------------| | | I have an app header which consists of the app title and a button. The button should be fixed on the right side but I want the title to be in the middle and ellipsize when the screen is too small. Problem is the title just won't ellipsize even though the button is nearly beside it. Here's what I have so far: <RelativeLayout android:id="@+id/headr" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center"> <ImageView android:id="@+id/bar_orange" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:minHeight="40dp" android:scaleType="centerCrop" android:src="@drawable/bar_orange"/> <TextView android:id="@+id/Title" android:layout_marginLeft="20dp" android:layout_marginRight="20dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:gravity="center" android:text="@string/bcd" android:textColor="#FFFFFF" android:ellipsize="marquee" android:singleLine="true" android:textSize="18sp" android:textStyle="bold"/> <Button android:padding="5dp" android:id="@+id/home" android:textColor="#ffffff" android:layout_marginRight="10dp" android:layout_marginLeft="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:singleLine="true" android:background="@drawable/button_home" android:text="@string/home"/> </RelativeLayout> Is there a way to do this with just RelativeLayout?

  I'm trying to use a ListView inside of a RelativeLayout but when I run my app I get a runtimeexception with the message: Binary XML file line #2: You must supply a layout_width attribute. I tried putting layout_width attributes in every conceivable place in the xml resource files but so far no luck. I attempt to populate the listview with this line of code: setListAdapter(new ArrayAdapter(this, R.layout.tablerow3, R.id.label, items)); Here's the tablerow3.xml contents: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"> android:layout_width="20dp" android:layout_height="5dp" android:id="@+id/tablerow01"> <Label android:id="@+id/label01" android:layout_width="5dp" android:layout_height="5dp" android:textColor="@color/solid_white" android:singleLine="true"/> <Label android:id="@+id/label02" android:layout_width="5dp" android:layout_height="5dp" android:textColor="@color/solid_white" android:singleLine="true"/> </LinearLayout> Here's the xml that contains the RelativeLayout(forex2.xml): <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Button android:text="Static Button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:id="@+id/button_id"> </Button> <Spinner android:id="@+id/spinner1" android:layout_width="match_parent" android:layout_toRightOf="@id/button_id" android:layout_alignParentTop="true" android:layout_height="wrap_content" android:drawSelectorOnTop="true" /> <ListView android:id="@android:id/list" android:layout_width="5dp" android:layout_height="5dp" android:layout_alignParentBottom="true" /> <!-- android:layout_width="wrap_content" android:layout_height="wrap_content" --> </RelativeLayout>

• LinearLayout - How to get text to be on the right of an icon?

  - by RED_

  Hi there, Bit of a newbie when it comes to android, only been working on it properly for a few days but even after all the searching I've done im stumped and nobody seems to know how to help me. I have this so far: http://img263.imageshack.us/i/sellscreen.jpg How can I move the text to be besides each icon rather than underneath it? Hoping the gallery won't be moved either. Here is the code i have: <?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/scroller" android:layout_width="fill_parent" android:layout_height="fill_parent" android:fillViewport="true" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Gallery xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/gallery" android:layout_width="fill_parent" android:layout_height="wrap_content"/> <ImageView android:id="@+id/test_image" android:src="@drawable/icon" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="The offcial UK driving theory test application. Over 190 questions." /> <ImageView android:id="@+id/test_image" android:src="@drawable/icon" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="The offcial UK driving theory test application. Over 190 questions."/> <ImageView android:id="@+id/test_image" android:src="@drawable/icon" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="The offcial UK driving theory test application. Over 190 questions."/> <ImageView android:id="@+id/test_image" android:src="@drawable/icon" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="The offcial UK driving theory test application. Over 190 questions."/> <ImageView android:id="@+id/test_image" android:src="@drawable/icon" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="The offcial UK driving theory test application. Over 190 questions." /> </LinearLayout> </ScrollView> Top half of my code doesn't seem to be showing for some reason but it's just the opening of the linear layout. I will be forever grateful to anyone that can help, i've been racking my brains for days and getting nowhere. Really getting stressed out by it. Thanks in advance!!

• Android -Layout Manager not showing buttons

  - by Arun

  The following is my code. I want an interface where I have a single line textbox, a multiline textbox with 2 buttons below. I want the multiline textbox to occupy all the space available after rendering the buttons and textbox. For this I created two LinearLayouts inside the main layout. The first one has vertical orientation with layout_width set to fill_parent. The second one is horizontal with fill_parent again. The first one has a textbox for which I have set the layout_height to fill parent. The second one has two textboxes OK and Cancel. When I run this application I get the UI, but the Buttons are very small. I have to set the button height manually. What am I doing wrong here. I don't want to hard code the button height. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Name"></TextView> <EditText android:layout_width="fill_parent" android:layout_height="wrap_content"></EditText> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Contents"></TextView> <EditText android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="top" /> </LinearLayout> <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1"> <Button android:id="@+id/okbutt" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="OK" android:layout_weight="1" /> <Button android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="Cancel" android:layout_weight="1" /> </LinearLayout> Thanks, Arun
