  • 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. If i remove the above line everything works fine. LogCat says: updateAppWidget couldn't find any view, using error view android.widget.RemoteViews$ActionException: view: android.widget.TextView can't use method with RemoteViews: setBackgroundResource(int)

  • 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 AppWidget TextView: How to set background color at run time

  • 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.

  • Problem with sizes of EditText and Button in Android

    - by DixieFlatline
    I want to make the edittext width the same size as button. My EditText is currently very small.

  • 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?

  • Android listview array adapter selected

    - by João Melo
    i'm trying to add a contextual action mode to a listview, but i'm having some problems with the selection, if i make aList1.setSelection(position) it doesn't select anything, and if i make List1.setItemChecked(position, true) it works but it only changes the font color a little and i want it to change the background or something more notable, is there any way to detect the selection and manually and change the background, or i'm missing something? the list: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <ListView android:id="@+id/list1" android:layout_width="match_parent" android:layout_height="match_parent" android:choiceMode="singleChoice" android:drawSelectorOnTop="false"> </ListView> </RelativeLayout> the adapter: public class ServicesRowAdapter extends ArrayAdapter<String[]> { private final Activity context; private final ArrayList<String[]> names; static class ViewHolder { public TextView Id; public TextView Date; public RelativeLayout statusbar,bglayout; } public ServicesRowAdapter(Activity context, ArrayList<String[]> names) { super(context, R.layout.servicesrowlayout, names); this.context = context; this.names = names; } @Override public View getView(int position, View convertView, ViewGroup parent) { View rowView = convertView; if (rowView == null) { LayoutInflater inflater = context.getLayoutInflater(); rowView = inflater.inflate(R.layout.servicesrowlayout, null); ViewHolder viewHolder = new ViewHolder(); viewHolder.Id = (TextView) rowView.findViewById(R.id.idlabel); viewHolder.Date = (TextView) rowView.findViewById(R.id.datelabel); rowView.setTag(viewHolder); } ViewHolder holder = (ViewHolder) rowView.getTag(); holder.Date.setText(names.get(position)[2]); holder.Id.setText(names.get(position)[1]); return rowView; } } with the use of a layout: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" > <TextView android:id="@+id/idlabel" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:gravity="right" android:text="@+id/idlabel" android:textSize="20dp" android:width="70dp" > </TextView> <TextView android:id="@+id/datelabel" android:layout_centerVertical="true" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@+id/datelabel" android:textSize="20dp" android:layout_marginLeft="90dp" > </TextView> </RelativeLayout

  • 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. Ubuntu comes with ABSOLUTELY NO WARRANTY, to the extent permitted by applicable law.

  • Mock Objects for Unit Testing

    - by user9009
    Hello How often QA engineers are responsible for developing Mock Objects for Unit Testing. So dealing with Mock Objects is just developer job ?. The reason i ask is i'm interested in QA as my career and am learning tools like JUnit , TestNG and couple of frameworks. I just want to know until what level of unit testing is done by developer and from what point QA engineer takes over testing for better test coverage ? Thanks

  • Angry Bird Makers: Developers Love iOS Over Android To Make Money

    - by Gopinath
    These days web is buzzing with Apple iOS vs Google Android debates. Recently Fortune predicted that Android is going to explode in 2011 and it will surpass Apple’s iOS market share. Yes Android is set to spread its wings across all the devices – smartphones, TVs, set top boxes, in car entertainment devices, what not. Think of any device that requires operating system, Android can be used. On the other than iOS is only available on very selective Apple devices – iPods, iPhones and iPads. When it comes to the count of devices running on a specific OS, Android will be far ahead of iOS but when you consider a quality of devices and providing an eco system for business to make money iOS seems to be the winner. That is what experts and analysts are saysing. Here is an excerpt from Peter Vesterbacka, maker of the popular Angry Birds game, interview to Tech N Marketing site.  He says Apple will be the number one platform for a long time from a developer perspective, they have gotten so many things right. And they know what they are doing and they call the shots. Android is growing, but it’s also growing complexity at the same time. Device fragmentation not the issue, but rather the fragmentation of the ecosystem. So many different shops, so many different models. The carriers messing with the experience again. Open but not really open, a very Google centric ecosystem. And paid content just doesn’t work on Android. Peter says developer prefer iOS over Android as it’s not very easy to make money on Android market. That’s why they released a free version of Angry Birds game with ads support for Android devices. Free is the way to go with Android. Nobody has been successful selling content on Android. We will offer a way to remove the ads by paying for the app, but we don’t expect that to be a huge revenue stream.

  • Development processes, the use of version control, and unit-testing

    - by ct01
    Preface I've worked at quite a few "flat" organizations in my time. Most of the version control policy/process has been "only commit after it's been tested". We were constantly committing at each place to "trunk" (cvs/svn). The same was true with unit-testing - it's always been a "we need to do this" mentality but it never really materializes in a substantive form b/c there is no institutional knowledge base to do it - no mentorship. Version Control The emphasis for version control management at one place was a very strict protocol for commit messages (format & content). The other places let employees just do "whatever". The branching, tagging, committing, rolling back, and merging aspect of things was always ill defined and almost never used. This sort of seems to leave the version control system in the position of being a fancy file-storage mechanism with a meta-data component that never really gets accessed/utilized. (The same was true for unit testing and committing code to the source tree) Unit tests It seems there's a prevailing "we must/should do this" mentality in most places I've worked. As a policy or standard operating procedure it never gets implemented because there seems to be a very ill-defined understanding about what that means, what is going to be tested, and how to do it. Summary It seems most places I've been to think version control and unit testing is "important" b/c the trendy trade journals say it is but, if there's very little mentorship to use these tools or any real business policies, then the full power of version control/unit testing is never really expressed. So grunts, like myself, never really have a complete understanding of the point beyond that "it's a good thing" and "we should do it". Question I was wondering if there are blogs, books, white-papers, or online journals about what one could call the business process or "standard operating procedures" or uses cases for version control and unit testing? I want to know more than the trade journals tell me and get serious about doing these things. PS: @Henrik Hansen had a great comment about the lack of definition for the question. I'm not interested in a specific unit-testing/versioning product or methodology (like, XP) - my interest is more about work-flow at the individual team/developer level than evangelism. This is more-or-less a by product of the management situation I've operated under more than a lack of reading software engineering books or magazines about development processes. A lot of what I've seen/read is more marketing oriented material than any specifically enumerated description of "well, this is how our shop operates".

  • Advancing Code Review and Unit Testing Practice

    - by Graviton
    As a team lead managing a group of developers with no experience ( and see no need) in code review and unit testing, how can you advance code review and unit testing practice? How are you going to create a way so that code review and unit testing to naturally fit into the developer's flow? One of the resistance of these two areas is that "we are always tight on dateline, so no time for code review and unit testing". Another resistance for code review is that we currently don't know how to do it. Should we review the code upon every check-in, or review the code at a specified date?
