问题描述
我想知道是否有可能得到的坐标,留下了ImageView的和顶部。我有2的ImageView内的滚动型一个RelativeLayout的内部。我试图获取的ImageView的矩阵矩阵= _iv.getImageMatrix();
,但它是没有帮助的矩阵{[1.0,0.0,0.0 ] [0.0,1.0,0.0] [0.0,0.0,1.0]}
。有任何想法吗?难道有所作为,如果 getImageMatix()
运行在不同的地方?
I would like to know if it is possible to get the coordinates, left and top, of an ImageView.I have 2 ImageView inside a RelativeLayout inside a ScrollView.I tried to retrieve the matrix of the ImageView with matrix = _iv.getImageMatrix();
but it is not helpful Matrix{[1.0, 0.0, 0.0][0.0, 1.0, 0.0][0.0, 0.0, 1.0]}
.Any ideas? Would it make a difference if the getImageMatix()
is run in a different place?
推荐答案
下面是一个更好的方式来做到这一点。我实现在ImageView的本身和X的OnTouchListener,Y坐标在相应于ImageView的
Here's a better way to do it. I implemented an OnTouchListener in the ImageView itself and the X,Y coordinates are corresponding to the ImageView.
_iv.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
//Choose which motion action has been performed
switch(event.getAction())
{
case MotionEvent.ACTION_DOWN:
//Get X, Y coordinates from the ImageView
int X = (int) event.getX();
int Y = (int) event.getY();
//Do something
break;
case MotionEvent.ACTION_MOVE:
break;
case MotionEvent.ACTION_UP:
break;
}
return true;
}
}); //End setOnTouchListner()
