Question

看起来很简单，但不知怎的，我无法弄清楚如何找到左（x）和上（y）坐标的视图我几乎尝试了每个答案，每个人都给零。

这是xml

**Code snippet to find out co-ordinate**
private void showUseSearch() {

    View etSearchTextList = findViewById(R.id.et_inputSearch);
    int[] tableLayoutCorners = new int[2];

    Rect myViewRect = new Rect();
    etSearchTextList.getGlobalVisibleRect(myViewRect);
    float x = myViewRect.left;
    float y = myViewRect.top;

    etSearchTextList.getLocationInWindow(tableLayoutCorners);

    Log.i(TAG, x+","+y+"-"+tableLayoutCorners[0] + "-" + tableLayoutCorners[1] + ",showUseSearch: " + etSearchTextList.getX() + "," + etSearchTextList.getY() + "-" + etSearchTextList.getPivotX() + "-" + etSearchTextList.getPivotY());
    }

如果您在完全渲染UI之前尝试获取位置，则会将其设为零。在绑定UI之后，您可以使用treeObserver侦听器来获取x和y。你走了：

view.getViewTreeObserver().addOnGlobalLayoutListener(
    new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            // Layout has happened here.
            int x = (int)view.getX();// returns float
            int y = (int)view.getY();

            // Don't forget to remove your listener when you are done with it.
            view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
        }
    });
