如何分离 Button Longpress Button press Up 和 Down 事件

Question

我有点击功能和长按同一个按钮。实现了长按事件，但是，我需要分别找到按钮 UP_EVENT 和 DOWN_EVENTS。如何使用 OnLongClickListener

来实现

 View.OnLongClickListener listener = new View.OnLongClickListener() {

            @Override
            public boolean onLongClick(View view) {

                return true;
            }

        };

Answer 1

Implement a TouchListener within the onLongClickListener:

    View.OnLongClickListener listener = new View.OnLongClickListener() {

        @Override
        public boolean onLongClick(View view) {
            view.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    switch (event.getAction()) {
                        case MotionEvent.ACTION_DOWN:
                            // PRESSED
                            return true; // if you want to handle the touch event
                        case MotionEvent.ACTION_UP:
                            // RELEASED
                            return true; // if you want to handle the touch event
                    }
                    return false;
                }
            });
            return true;
        }

    };

Answer 2

要检测 ACTION_UP 和 ACTION_DOWN 事件，您需要实施 OnTouchListener。

Answer 3

要分开，可以这样

@Override
public boolean onTouchEvent(MotionEvent ev) {
    switch (ev.getAction() & MotionEvent.ACTION_MASK) {
        case MotionEvent.ACTION_DOWN:

            break;
        case MotionEvent.ACTION_CANCEL:
        case MotionEvent.ACTION_UP:
            if (isOnClick) {                    
                //TODO onClick code
            }
            break;
        case MotionEvent.ACTION_MOVE:

            }
            break;
        default:
            break;
    }
    return true;
}
