如何在Android中使用(X，Y)接收来自触摸事件的Y来移动图像？

<ImageView
    android:id="@+id/imageView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/image" />

ImageView imageView = findViewById(R.id.imageView);
imageView.setOnTouchListener(new View.OnTouchListener() {
    float startX, startY;

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                startX = event.getX();
                startY = event.getY();
                break;
            case MotionEvent.ACTION_MOVE:
                float offsetX = event.getX() - startX;
                float offsetY = event.getY() - startY;
                imageView.setX(imageView.getX() + offsetX);
                imageView.setY(imageView.getY() + offsetY);
                break;
        }
        return true;
    }
});
