  • Problem with TextViews running into each other in RelativeLayout

    - by Janusz
    I have a problem with two Textviews on the same height in a RelativeLayout running into each other. I use the following Layout. <?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"> <ImageView android:id="@+id/logo" android:layout_width="wrap_content" android:layout_height="wrap_content" android:adjustViewBounds="true" android:scaleType="centerInside" android:src="@drawable/icon" /> <TextView android:id="@+id/name" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="NameNameNameNameNameNameName" android:layout_alignParentTop="true" android:layout_toRightOf="@id/logo" android:gravity="clip_horizontal" android:lines="1" /> <TextView android:id="@+id/information" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="information" android:layout_alignParentRight="true" android:layout_alignParentTop="true" /> <TextView android:id="@+id/nrcoupons" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Number" android:layout_alignRight="@id/information" android:layout_alignBottom="@id/logo" /> <TextView android:id="@+id/subcategory" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Subcategory" android:layout_alignLeft="@id/name" android:layout_alignBottom="@id/logo" /> </RelativeLayout> This gives me this view: Everything is as I need it except the two textviews name and information are displayed on the same screen space with the one on top of the other. How can I avoid this?

  • Is there a difference between starting an application from the OS or from adb

    - by aruwen
    I do have a curious error in my application. My app crashes (don't mind the crash, I roughly know why - classloader) when I start the application from the OS directly, then kill it from the background via any Task Killer (this is one of the few ways to reproduce the crash consistently - simulating the OS freeing memory and closing the application) and try to restart it again. The thing is, if I start the application via adb shell using the following command: adb shell am start -a android.intent.action.MAIN -n com.my.packagename/myLaunchActivity I cannot reproduce the crash. So is there any difference in how Android OS calls the application as opposed to the above call? EDIT: added the manifest (just changed names) <?xml version="1.0" ?> <manifest android:versionCode="5" android:versionName="1.05" package="com.my.sample" xmlns:android="http://schemas.android.com/apk/res/android"> <uses-sdk android:minSdkVersion="7"/> <application android:icon="@drawable/square_my_logo" android:label="@string/app_name"> <activity android:label="@string/app_name" android:name="com.my.InfoActivity" android:screenOrientation="landscape"></activity> <activity android:label="@string/app_name" android:name="com.my2.KickStart" android:screenOrientation="landscape"/> <activity android:label="@string/app_name" android:name="com.my2.Launcher" android:screenOrientation="landscape"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> </application> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/></manifest> starting the com.my2.Launcher from the adb shell

  • Spinner original text

    - by user1696863
    I'm trying my Spinner to display "Select City" before the Spinner has itself been clicked by the user. How can I do this? My current XML code is: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:custom="http://schemas.android.com/apk/res/com.olacabs.customer" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/page_background" android:orientation="vertical" > <TextView android:id="@+id/textView1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@android:color/darker_gray" android:gravity="center" android:paddingBottom="4dp" android:paddingTop="4dp" android:text="@string/rate_card" android:textColor="@color/white" android:textSize="20dp" custom:customFont="litera_bold.ttf" /> <Spinner android:id="@+id/select_city" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginTop="40dp" android:prompt="@string/selectCity" /> </LinearLayout> Also, what does android:spinnerMode exactly do. I tried changing its value to dropdown but nothing happened and the application still showed a popup dialogue. My activity that implements this XML file is: public class RateCardActivity extends OlaActivity { public void onCreate(Bundle bundle) { super.onCreate(bundle); setContentView(R.layout.rate_card); Spinner spinner = (Spinner) findViewById(R.id.select_city); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.select_city, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); } }

  • Layout: how to make image to change its width and height proportionally?

    - by Exterminator13
    I have such layout: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_centerVertical="true" android:layout_toLeftOf="@+id/my_image" android:ellipsize="end" android:singleLine="true" android:text="Some text" android:textAppearance="?android:attr/textAppearanceMedium" /> <ImageView android:id="@+id/my_image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignTop="@+id/title" android:layout_alignBottom="@+id/title" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:adjustViewBounds="true" android:src="@drawable/my_bitmap_image" /> This layout does almost what I need: it makes image view height the same as text view. The image graphic contents stretched also keeping aspect ratio. But, the width of the image view does not change! As a result, I have a wide gap between text and the image view! As a temporal solution, I override View#onLayout. The question: how to change image width in xml layout? UPDATE: This is a final layout I need (text + a few images). Look at the first image: its width should be exactly the same as scaled image in it with no paddings and margins:

  • Android AppWidget TextView: How to set background color programmaticly

    - by Amit
    I am trying to create an AppWidget, in which the background color of a TextView changes at random at specified periodic interval. The TextView is defined in layout xml file as <?xml version="1.0" encoding="utf-8" ?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/widget" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" > <TextView android:id="@+id/message" android:background="#ff99ff" android:text="Hello Widget" /> </LinearLayout> In update method, i have loaded the layout as RemoteViews remoteView=new RemoteViews(context.getPackageName(),R.layout.widget_message); To change the background of TextView i used the following statement remoteView.setInt(R.id.message, "setBackgroundResource", R.color.col_1); But i am getting a widget saying problem loading widget.

  • GridView row remove and animation - Android

    - by Pria
    I have a GridView in which each row has a custom view. The grid view adapter has an array that keeps the custom view. At click of a button, I want to remove a specific row from the Grid and while doing so I want animation on it. I have an AnimationListener. When I remove the upper most row from the array and setAdapter in onAnimationEnd(). It works perfectly fine. But, when I remove any other row, it gives a NullPointerException in the main thread. The exception thread is as follows: ERROR/AndroidRuntime(11503): java.lang.NullPointerException at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1227) at android.widget.AbsListView.dispatchDraw(AbsListView.java:1319) at android.view.View.draw(View.java:5944) at android.widget.AbsListView.draw(AbsListView.java:2121) at android.view.ViewGroup.drawChild(ViewGroup.java:1486) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1228) at android.view.View.draw(View.java:5841) at android.widget.FrameLayout.draw(FrameLayout.java:352) at android.view.ViewGroup.drawChild(ViewGroup.java:1486) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1228) at android.view.View.draw(View.java:5841) at android.widget.FrameLayout.draw(FrameLayout.java:352) at android.view.ViewGroup.drawChild(ViewGroup.java:1486) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1228) at android.view.View.draw(View.java:5841) at android.widget.FrameLayout.draw(FrameLayout.java:352) at com.android.internal.policy.impl.PhoneWindow$DecorView.draw(PhoneWindow.java:1847) at android.view.ViewRoot.draw(ViewRoot.java:1217) at android.view.ViewRoot.performTraversals(ViewRoot.java:1030) at android.view.ViewRoot.handleMessage(ViewRoot.java:1482) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:3948) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:782) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:540) at dalvik.system.NativeStart.main(Native Method) Please help!!!

  • android: start an intent into a framelayout

    - by user329692
    Hi guys! I have a main activity with this layout file: <?xml version="1.0" encoding="utf-8"?> <Button android:id="@+id/btn_reload" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Reload" /> <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center_vertical|center_horizontal" > <ImageView android:id="@+id/ImageView01" android:src="@drawable/logo_head" android:scaleType="fitStart" android:adjustViewBounds="true" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> </LinearLayout> <FrameLayout android:id="@+id/center" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1"> </FrameLayout> <LinearLayout android:layout_height="fill_parent" android:layout_width="fill_parent" android:gravity="center" android:id="@+id/footer" android:layout_weight="2.6" android:background="#ffffff"> </LinearLayout> Basically it is composed by an header, a central part (android:id="@+id/center") and a footer. The footer contains four buttons, created dinamically. At the end it looks like a TabWidget with the tabs at the botton. Each footer's buttons holds an Intent/activity. The question is: How can i start my activity into the FrameLayout? For instance TabHost does this: ..... spec = tabHost .newTabSpec(tabTitle.toLowerCase()) .setIndicator(tabTitle,res.getDrawable(R.drawable.tab_spec)) .setContent(intent); tabHost.addTab(spec); ....

  • Android crashes when calling ImageButton

    - by Joël
    I have a crash (Application Stopped Unexpectedly) problem with this main.xml is a "HelloWorld" type project (while testing and learning features I need for my app) : I isolated the ImageButton as an issue, but I can't isolate any of the parameters... <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ImageButton android:id="@+id/picture" android:layout_width="240dip" android:layout_height="180dip" android:layout_gravity="center_horizontal" android:src="@drawable/icon" android:adjustViewBounds="true" android:cropToPadding="true" android:clickable="true" android:scaleType="fitCenter" /> </LinearLayout> icon.png exists in my resources... I can see the preview in the Layout tab, even though the image is not centered on the button, but I read that it was normal. The code below works fine (as a regular Button). I can also do the same as an ImageView. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:id="@+id/picture" android:layout_width="240dip" android:layout_height="180dip" android:layout_gravity="center_horizontal" /> </LinearLayout> I use Eclipse and the AVD, and all my learning is done on 2.1 (SDK level 7). I can't test the app on an actual device yet as I don't have it yet. Thanks in advance !

  • Android customizing ViewFlipper...

    - by wearysamurai
    So I'm having pretty much exactly the problem described here: http://code.google.com/p/android/issues/detail?id=6191 and until the ViewFlipper issue in 2.1 and 2.2 has been resolved, I'm attempting to customize my own ViewFlipper in the manner described: @Override protected void onDetachedFromWindow() { try { super.onDetachedFromWindow(); } catch (IllegalArgumentException e) { // Call stopFlipping() in order to kick off updateRunning() stopFlipping(); } } But I've never done this sort of thing before and am hoping to get a little guidance (as my own efforts are coming up short). Here's what I have so far. FixedFlipper.java: import android.content.Context; import android.util.AttributeSet; import android.widget.ViewFlipper; public class FixedFlipper extends ViewFlipper{ public FixedFlipper(Context context){ super(context); } public FixedFlipper(Context context, AttributeSet attrs){ super(context, attrs); } @Override protected void onDetachedFromWindow(){ try{ super.onDetachedFromWindow(); }catch(Exception e){ super.stopFlipping(); } } } main.xml: <com.site.TestApp.FixedFlipper style="@style/body" android:id="@+id/flipper"> ... </com.site.TestApp.FixedFlipper> And in my activity, I invoke it like so: FixedFlipper flipper = (FixedFlipper)findViewById(R.id.flipper); It seems like it should be pretty straightforward, but I keep getting this: Binary XML file line #4: Error inflating class com.site.TestApp.FixedFlipper I appreciate any suggestions. I've been chasing my tail for hours trying to figure out what piece of the puzzle I'm missing.

  • Bug in the official Android Fragments training sample?

    - by Jeff Axelrod
    It seems to me that there must be a bug in the Android Fragments demo. As background, Fragments are apparently sometimes instantiated by the Android OS and thus need a public no-arg constructor: All subclasses of Fragment must include a public empty constructor. The framework will often re-instantiate a fragment class when needed, in particular during state restore, and needs to be able to find this constructor to instantiate it. If the empty constructor is not available, a runtime exception will occur in some cases during state restore. But the NewsReader demo from the official Android training on Fragments constructs the HeadlinesFragment class and configures it with setOnHeadlineSelectedListener(this) from NewsReaderActivity.onCreate(). If the Android OS re-instantiates this fragment, the mHeadlineSelectedListener field will be null because HeadlinesFragment doesn't save or restore its state. Is this a bug or am I missing something?

  • VerifyError When Running jUnit Test on Android 1.6

    - by DKnowles
    Here's what I'm trying to run on Android 1.6: package com.healthlogger.test; public class AllTests extends TestSuite { public static Test suite() { return new TestSuiteBuilder(AllTests.class).includeAllPackagesUnderHere().build(); } } and: package com.healthlogger.test; public class RecordTest extends AndroidTestCase { /** * Ensures that the constructor will not take a null data tag. */ @Test(expected=AssertionFailedError.class) public void testNullDataTagInConstructor() { Record r = new Record(null, Calendar.getInstance(), "Data"); fail("Failed to catch null data tag."); } } The main project is HealthLogger. These are run from a separate test project (HealthLoggerTest). HealthLogger and jUnit4 are in HealthLoggerTest's build path. jUnit4 is also in HealthLogger's build path. The class "Record" is located in com.healthlogger. Commenting out the "@Test..." and "Record r..." lines allows this test to run. When they are uncommented, I get a VerifyError exception. I am severely blocked by this; why is it happening?

  • Android listview array adapter selected

    - by João Melo

  • Android refresh StateListDrawable problem

    - by Max
    Hi all, I have a strange problem with StateListDrawable or maybe (probably) I'm missing something. I created a test application for it and the same problem occurs. So, this is my StateListDrawable resourse in file test_selection.xml <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_selected="true"> <shape android:shape="rectangle" android:background="#ff0000"> <corners android:radius="10dp" /> <gradient android:startColor="#ff5555" android:endColor="#ff5555" android:angle="0" /> </shape> </item> <item android:state_selected="false"> <shape android:shape="rectangle" android:background="#eeeeee"> <corners android:radius="10dp" /> <gradient android:startColor="#eeeeee" android:endColor="#eeeeee" android:angle="0" /> </shape> </item> </selector> It's a very simple selector that draw a red color for selected state and a white rect for the unselected one. My main.xml template is very simple. I simply use a TextView that uses the selection as background. <?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:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" android:textSize="30dp" android:id="@+id/test_view_example" android:background="@drawable/test_selection"/> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/refresh" android:onClick="updateView" android:text="refresh"></Button> </LinearLayout> My Activity code is also very simple. public class TestDrawableStateActivity extends Activity { private final static int[] SELECTED_STATE = { android.R.attr.state_selected }; private final static int[] UNSELECTED_STATE = {}; private TextView textView; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); textView = (TextView) findViewById(R.id.test_view_example); } @Override protected void onResume() { super.onResume(); // Carichiamo la Drawable if(textView.getBackground().setState(SELECTED_STATE)){ textView.invalidate(); } } public void updateView(View view) { if(textView.getBackground().setState(SELECTED_STATE)){ textView.invalidate(); }; } } When Activity starts I try to set the state of my Drawable (the StateListDrawable) with the value SELECTED. It seems all very simple.... but the problem is that the state is not shown. If, later, I click a button and execute the method updateView() the state changes. Where is my problem? Where am I wrong? Thankx a lot Max

  • LinearLayout as custom button, OnClickListener never called

    - by ohra
    I've been using the common Android Button with both icon (drawableTop) and text. It works really poorly if you want to have a non-standard size button, so I decided to make a custom button with a LinearLayout having the following layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" style="@style/ButtonHoloDark" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:clickable="true" android:focusable="true" android:orientation="vertical" > <ImageView android:id="@+id/buttonIcon" android:layout_width="fill_parent" android:layout_height="wrap_content" android:duplicateParentState="true" /> <TextView android:id="@+id/buttonText" android:layout_width="fill_parent" android:layout_height="wrap_content" android:duplicateParentState="true" android:gravity="center" android:textColor="@color/white" /> </LinearLayout> The layout is used by a custom class: public class CustomIconButton extends LinearLayout { public CustomIconButton(Context context, AttributeSet attrs) { super(context, attrs); setAttributes(context, attrs); LayoutInflater.from(context).inflate(R.layout.custom_icon_button, this, true); } ... But when I set an OnClickListener on my button in its parent layout it never gets called. I can only receive clicks if a set the listener to the ImageView and/or TextView. This leads to two possible effects when the button is clicked: The click is inside the ImageView or the TextView. The click is registered ok, but the buttons state drawable doesn't change i.e. it doesn't appear depressed. The click is inside the "empty area" of the button. The click is not registered, but the state drawable works ok. Neither of these is feasible. I've played around with the following attributes on the LinearLayout or its children, but none really seem to have any effect whether true or false: duplicateParentState clickable focusable There doesn't seem to be any reasonable way to get the LinearLayout parent receive clicks instead of its children. I've seen some possible solutions overriding dispatchTouchEvent or onInterceptTouchEvent on the custom component itself, but that really seems like a big mess if I have to start analyzing touch events to identify proper clicks. So OnClickListener on a LinearLayout with children = no go?

  • Ubuntu.sh on Android Phone

    - by pjtatlow
    So today I noticed something weird on my phone. I used a terminal emulator to see what I could do with it, and noticed that there is a file called ubuntu.sh. I tried to run it and got all sorts of permission denied errors, and then I decided to root my phone. But now I'm nervous to run it, does anyone know what it does or why it is there? edit I forgot to mention that I have an AT&T Morotola Atrix 4G running Android 2.3.6. Also when I use the app SSHDroid to go into my phone from my Ubuntu machine, I'm greeted with this: "The programs included with the Ubuntu system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.
