Hello, My end result is to increase the clickable area of certain views that are small. It appears that this can be done with a TouchDelegate<http://groups.google.com/group/android-developers/browse_thread/thread/178af525ab84b371>, but in my case, there will be scenarios where one container has multiple views that I would like to increase the hit area for. Comments from this Stack Overflow question<http://stackoverflow.com/questions/1343222/is-there-an-example-of-how-to-use-a-touchdelegate-in-android-to-increase-the-siz>suggest this method can only be done for a single view inside a ViewGroup.
So, I've attempted to override getHitRect<http://developer.android.com/reference/android/view/View.html#getHitRect%28android.graphics.Rect%29>on a subclass of View, to increase the area. The example program below attempts to make the area 100px above and below a button clickable. The results are as follows: - Emulator running 2.2: The area above and below is clickable, clicking that area makes toast. - Nexus One running 2.3.6: The getHitRect method gets called, but the click method is not fired when clicking above/below the button. - Galaxy Nexus running 4.0.4: The getHitRect method never gets called, and hence, no click event when clicking above/below the button. My question is twofold: 1) Is there a more elegant way to increase the click area of multiple views inside one ViewGroup? 2) Just out of curiosity, how is the getHitRect method supposed to work/be used? Is it deprecated? Here's the short example: public class TestActivity extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); /* simply create a layout with some whitespace surrounding an instance of my custom button */ LinearLayout container = new LinearLayout(this); container.setGravity(Gravity.CENTER_VERTICAL); container.setOrientation(LinearLayout.VERTICAL); TestButton button = new TestButton(this); button.setText("Make Toast"); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Toast.makeText(TestActivity.this, "button was clicked", Toast.LENGTH_SHORT).show(); } }); container.addView(button); setContentView(container); } public static class TestButton extends Button { public TestButton(Context context) { super(context); } @Override public void getHitRect(Rect outRect) { super.getHitRect(outRect); /* just an example, for test purposes */ outRect.top -= 100; outRect.bottom += 100; Log.d("TestActivity", "getHitRect called, value: " + outRect.toShortString()); } } } -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
