如何根据焦点显示前景中的视图？

Posted 2021-04-19

JAVA代码：

 mEdtTextPickup.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if(hasFocus){
                    mLayoutDrop.invalidate();
                    mEdtTextPickup.bringToFront();
                }
            }
        });
        mEdtTextDrop.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if(hasFocus){
                    mLayoutPickup.invalidate();
                    mEdtTextDrop.bringToFront();
                }
            }
        });

`我的应用程序Source和Destination中有两个布局，其中一个布局与FrameLayout内的另一个重叠。（就像附图一样）

现在，如何在聚焦时将目标布局置于动画源布局之上。我google了很多，但没有找到解决方案。

答案

You can use a focus change listener to identify when the field is focused and then bringToFront to bring the view above the others.

destinationEditText.setOnFocusChangeListener(new OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                edittext.bringToFront();

            } 
        }
    });
