Use the ViewPager.onPageChangeListener: viewPager.addOnPageChangeListener(new OnPageChangeListener() { public void onPageScrollStateChanged(int state) {} public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {} public void onPageSelected(int position) { // Check if this is the page you want. } });
Just found this and it works like a charm: myNumberPicker.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS); You can also set this in XML: android:descendantFocusability=”blocksDescendants”
Based on yghm’s workaround, I coded up a convenience class that allows me to solve the problem with a one-liner (after adding the new class to my source code of course). The one-liner is: AndroidBug5497Workaround.assistActivity(this); And the implementation class is: public class AndroidBug5497Workaround { // For more information, see https://issuetracker.google.com/issues/36911528 // To use this class, … Read more
I believe the OP is long gone, but in case this answer is able to help future searchers, I thought I’d post a solution that I have found. I have added this code into my onCreate() method: EDITED: 07/05/11 to include code from comments: final TextView tv = (TextView)findViewById(R.id.image_test); ViewTreeObserver vto = tv.getViewTreeObserver(); vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() … Read more
Actually you don’t need to extend any class. Let’s say I have an EditText editComment with a drawableRight editComment.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { final int DRAWABLE_LEFT = 0; final int DRAWABLE_TOP = 1; final int DRAWABLE_RIGHT = 2; final int DRAWABLE_BOTTOM = 3; if(event.getAction() == MotionEvent.ACTION_UP) { if(event.getRawX() >= … Read more
view.setPadding(0,padding,0,0); This will set the top padding to padding-pixels. If you want to set it in dp instead, you can do a conversion: float scale = getResources().getDisplayMetrics().density; int dpAsPixels = (int) (sizeInDp*scale + 0.5f);
With layout_weight you can specify a size ratio between multiple views. E.g. you have a MapView and a table which should show some additional information to the map. The map should use 3/4 of the screen and table should use 1/4 of the screen. Then you will set the layout_weight of the map to 3 … Read more
It may be too late but for the sake of others who have the same problem, to set the height of the ImageView: imageView.getLayoutParams().height = 20; Important. If you’re setting the height after the layout has already been ‘laid out’, make sure you also call: imageView.requestLayout();
