How do you to retrieve dimensions of a view? Getheight() and Getwidth() always return zero http://stackoverflow.com/questions/4142090/how-do-you-to-retrieve-dimensions-of-a-view-getheight-and-getwidth-always-r 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 @Override public void..
http://stackoverflow.com/questions/4381033/multi-gradient-shapes Okay so you can definitely fix the positioning through Java like the following TextView tv TextView findViewById R.id.image_test LayerDrawable ld LayerDrawable tv.getBackground int topInset tv.getHeight 2 does not work ld.setLayerInset 1 0 topInset.. description can be found here . This code should go in your onCreate method final TextView tv TextView findViewById R.id.image_test ViewTreeObserver vto tv.getViewTreeObserver vto.addOnGlobalLayoutListener new OnGlobalLayoutListener @Override public void..
When Can I First Measure a View? http://stackoverflow.com/questions/4393612/when-can-i-first-measure-a-view I put code such as the below so that the background changes upon display to the user TextView tv TextView findViewById R.id.image_test LayerDrawable ld LayerDrawable tv.getBackground int height tv.getHeight when to call this so as not to get 0 int topInset.. code it would look like this public void onCreate setContentView R.layout.main final TextView tv TextView findViewById R.id.image_test final LayerDrawable ld LayerDrawable tv.getBackground final ViewTreeObserver obs mTv.getViewTreeObserver obs.addOnPreDrawListener.. private int mLastTvHeight 0 public void onCreate setContentView R.layout.main final TextView tv TextView findViewById R.id.image_test final LayerDrawable ld LayerDrawable tv.getBackground final ViewTreeObserver obs mTv.getViewTreeObserver obs.addOnPreDrawListener..
