如何在Android中使用手势检测来拖动图片？

<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() {
    private float lastX, lastY;

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                lastX = event.getX();
                lastY = event.getY();
                break;
            case MotionEvent.ACTION_MOVE:
                float deltaX = event.getX() - lastX;
                float deltaY = event.getY() - lastY;
                float translationX = v.getTranslationX() + deltaX;
                float translationY = v.getTranslationY() + deltaY;
                v.setTranslationX(translationX);
                v.setTranslationY(translationY);
                break;
        }
        return true;
    }
});
