推荐答案

您需要替换的

public boolean onTouchEvent (MotionEvent e)

在活动的方式类，你是压倒一切的不是方法（ onTouch（...）的 OnTouchListener ）。那么它应该工作。例如：

method of the Activity class, not the method you are overriding (onTouch(...) of the OnTouchListener). Then it should work. Example:

@Override
public boolean onTouchEvent(MotionEvent e) {

    // do your stuff...

    return false;
}

这意味着你已经意识到在活动触摸事件，而不是在查看。如果你想明确地检测上的查看触摸通过 OnTouchListener ，需要设置 OnTouchListener 您查看。

This means you are recognizing touch events on the Activity, not on the View. If you want to explicitly detect touches on the View via OnTouchListener, you need to set the OnTouchListener for your View.

在您的情况：

fpv = new FartPianoView(this);
fpv.setOnTouchListener(this);
