如何使用GestureDetector的onForcePress属性？

import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;

public class MainActivity extends AppCompatActivity implements GestureDetector.OnGestureListener {

    private GestureDetector gestureDetector;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 初始化 GestureDetector
        gestureDetector = new GestureDetector(this, this);

        // 假设你有一个按钮需要监听手势
        findViewById(R.id.myButton).setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                // 将触摸事件传递给 GestureDetector
                return gestureDetector.onTouchEvent(event);
            }
        });
    }

    // 实现 GestureDetector.OnGestureListener 接口的方法
    @Override
    public void onForcePress(MotionEvent event) {
        super.onForcePress(event);
        // 处理长按加压力事件
        Toast.makeText(this, "Force Press Detected!", Toast.LENGTH_SHORT).show();
    }

    // 其他必须实现的接口方法（可以留空或根据需要实现）
    @Override
    public boolean onDown(MotionEvent e) { return false; }
    @Override
    public void onShowPress(MotionEvent e) {}
    @Override
    public boolean onSingleTapUp(MotionEvent e) { return false; }
    @Override
    public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { return false; }
    @Override
    public void onLongPress(MotionEvent e) {}
}
