java - 如何分离 Button Long Press Button press Up 和 Down 事件

Question

我有一个点击功能，长按同一个按钮。实现了长按事件，但我需要分别找到按钮 UP_EVENT 和 DOWN_EVENTS。如何使用 OnLongClickListener

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;
        }

    };
