只需放置 2 个手指并拖动它们一小段距离。应用程序停止并存在。我在下面发布我的代码。这段代码是唯一处理我的视图的 ontouchlistener 的部分。 

ScrollView scrollView = (ScrollView) findViewById(R.id.ScrollView11);
        scrollView.setOnTouchListener(textIncreaseListener);
    }

    private OnTouchListener textIncreaseListener = new OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {
            int count = event.getPointerCount();
            if(count == 2){
                Log.d(TAG, "2 pointers");
                return true;
            }
            return false;
        }
    };

有什么帮助吗？

问题在于 event.getPointerCount() ，将此行放入 try catch 块或简单地添加一个日志，您就会找到它。你到底想用这个scrollView做什么。
