After screen rotating, the height of one of view object is changed, I want to know the height value in pixel.
The onConfigurationChanged
method is likely called before view finishing rotation. So if I measure the view size in this method , the size is still the value of rotation before.
The problem is how can I get the view size value after rotation finish Without reconstructing Activity.
One possible solution:
private int viewHeight = 0;
View view = findViewByID(R.id.idOfTheView);
view.getViewTreeObserver().addOnGlobalLayoutListener(
new OnGlobalLayoutListener(){
@Override
public void onGlobalLayout() {
viewHeight = view.getHeight();
}
OR
@Override
public void onResume(){
int viewHeight = 0;
View view = findViewByID(R.id.idOfTheView);
viewHeight = view.getHeight();
}
