推荐答案
您可以使用 MotionEvent.ACTION_OUTSIDE
ImageButton i1 = (ImageButton)v.findViewById(R.id.imageButton1); i1.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
ImageButton button = (ImageButton)v;
String principal = "principal";
if (event.getAction() == MotionEvent.ACTION_DOWN) {
button.setColorFilter(0x8066bbdd);
return true;
} else if (event.getAction() == MotionEvent.ACTION_UP) {
button.setColorFilter(null);
Intent i = new Intent(getActivity(), SubView.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
i.putExtra("query", principal);
startActivity(i);
return true;
} else if(event.getAction() == MotionEvent.ACTION_OUTSIDE)
{
// Do some stuffs here
}
return false;
}
});
更新1：
如果 MotionEvent.ACTION_OUTSIDE 不工作，你可以尝试 MotionEvent.ACTION_CANCEL
If MotionEvent.ACTION_OUTSIDE Doesn't worked you can try MotionEvent.ACTION_CANCEL
