java - 我如何通过触摸将 ImageView 置于其他 ImageView 之上(android)

Question

它是左边的圆圈unpressed pressed

所以我有imageview =(成形的drawble src)，当我触摸它时将drawble res更改为其他所以颜色改变了。但我也想把它放在其他 ImageView 之上，我该怎么做，我尝试 BringToFront 但不起作用，还有其他方法吗？

当我按下一个 ImageView 时，我希望所有 ImageView 都处于其他 ImageView 的前面。

         final ImageView imageView = (ImageView) findViewById(R.id.cir);
        imageView.setOnTouchListener(new View.OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                Log.i("IMAGE", "motion event: " + event.toString());
                switch (event.getAction()) {
                    case MotionEvent.ACTION_DOWN: {
                        imageView.setImageResource(R.drawable.cir_press);
                        break;

                    }
                    case MotionEvent.ACTION_UP: {
                        imageView.setImageResource(R.drawable.cir);
                        break;
                    }
                }
                return false;
            }
        });

imgView.setVisibility(View.VISIBLE);

imgView.setVisibility(View.INVISIBLE);

imgView.setVisibility(View.GONE);

或者

<ImageView         
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:visibility="invisible"
    android:src="@drawable/your image" />
