custom-view

I've read a hell of a lot about this, and can't see anyone who's done or tried it before. So I've got an object that extends ImageView, then within this I call a progress dialog and set the progress dialogs's content to the imageview (i.e. attempting to draw the progress dialog in the imageview..view.) loadingProgressDialog.setContentView(this); //this is: LoaderImageView extends ImageView loadingProgressDialog.setIndeterminate(true); loadingProgressDialog.show(); And I get the error: requestFeature() must be called before adding content Now I've seen this error before on loads of posts and

How can I draw a button on top of the canvas in a custom view? (Preferably on the mid-right side) Is there something I have to call before doing the button.draw(canvas)? public class MyClass extends View { public Simulation(Context context) { super(context); pauseButton.setText("TestButton"); pauseButton.setClickable(true); pauseButton.setOnClickListener(new OnClickListener() { public void onClick(View v) { Log.i(TAG, "Button Pressed!"); } }); public onDraw(Canvas canvas) { super.onDraw(canvas); pauseButton.draw(canvas); } } Thanks for your time Lumis You cannot insert a button into canvas.

Is it possible to create a custom library in Android (having its own layout resources) for use across several Android applications? I created a regular *.jar file but when I tried to create/style my views dynamically most of the properties do not work. Even referencing simple styles from the android.jar file such as android.attr.listSeparatorTextViewStyle did not work. I created an Android project without any Activity, having its own resource files and then referenced this project from another Android project to use in its build path. Everything seems to work fine but the emulator keeps

I've got a custom view in which I need to draw two bitmaps, one is a background, representing the image of a map and one is a pin which will be drawn on top/left position in canvas. The both images are drawn onDraw and remain the same during the live of the activity that contains the view. After a while I get a OutOfMemoryError: bitmap size exceeds VM budget This means that I have a leak and the bitmaps don't get garbage collected. I asked this question before, but now the situation changed a little. I made a init method where I set the bitmaps I want to use but this still isn't a good

The Android data binding guide discusses binding values within an activity or fragment, but is there a way to perform data binding with a custom view? I would like to do something like: <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent"> <com.mypath.MyCustomView android:id="@+id/my_view" android:layout_width="match_parent" android:layout_height="40dp"/> </LinearLayout> with my_custom_view.xml : <layout> <data> <variable name="myViewModel" type="com.mypath.MyViewModelObject" /> </data> <LinearLayout android:layout_width="match_parent" android:layout_height=

I have a few ImageViews inside a LinearLayout. I need to scale down the ImageViews so that they maintain their aspect ratios whilst fitting inside the LinearLayout vertically. Horizontally, I just need them to be adjacent to each other. I've made a simplified test bed for this which nests weighted Layouts so that I have a wide, but not very tall, LinearLayout for the ImageViews - <?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">
