如何在android中为视图添加旋转和调整大小按钮

public class CustomView extends View {
    private Button rotateButton;
    private Button resizeButton;
    private float rotationAngle = 0;
    private int viewWidth;
    private int viewHeight;

    public CustomView(Context context) {
        super(context);
        init();
    }

    public CustomView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    private void init() {
        // 创建旋转按钮
        rotateButton = new Button(getContext());
        rotateButton.setText("旋转");
        rotateButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                rotateView();
            }
        });

        // 创建调整大小按钮
        resizeButton = new Button(getContext());
        resizeButton.setText("调整大小");
        resizeButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                resizeView();
            }
        });

        // 添加按钮到视图
        ViewGroup.LayoutParams layoutParams = new ViewGroup.LayoutParams(
                ViewGroup.LayoutParams.WRAP_CONTENT,
                ViewGroup.LayoutParams.WRAP_CONTENT);
        addView(rotateButton, layoutParams);
        addView(resizeButton, layoutParams);
    }

    private void rotateView() {
        rotationAngle += 45;
        this.setRotation(rotationAngle);
    }

    private void resizeView() {
        viewWidth += 50;
        viewHeight += 50;
        ViewGroup.LayoutParams layoutParams = getLayoutParams();
        layoutParams.width = viewWidth;
        layoutParams.height = viewHeight;
        setLayoutParams(layoutParams);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        // 处理触摸事件
        // 根据触摸事件的类型判断用户的操作
        // 实现视图的旋转和调整大小逻辑
        return true;
    }
}

<com.example.CustomView
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
