android 根据坐标返回触摸到的View

//根据坐标返回触摸到的View
private View getTouchTarget(View rootView, int x, int y) {
  View targetView = null;
  // 判断view是否可以聚焦
  ArrayList touchableViews = rootView.getTouchables();
  for (View touchableView : touchableViews){
    if (isTouchPointInView(touchableView, x, y)){
      targetView = touchableView;
      break;
    }
  }
  return targetView;
}

//(x,y)是否在view的区域内
private boolean isTouchPointInView(View view, int x, int y) {
  if (view == null){
    return false;
  }
  int[] position = new int[2];
  view.getLocationOnScreen(position);
  int left = position[0];
  int top = position[1];
  int right = left + view.getMeasuredWidth();
  int bottom = top + view.getMeasuredHeight();
  if (x >= left && x <= right && y >= top && y <= bottom){
    return true;
  }
  return false;
}

示例：

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {

//获取当前触摸到的View
final View touchedView = getTouchTarget(mContentView,(int) ev.getX(), (int) ev.getY());

return super.dispatchTouchEvent(ev);
}
