推荐答案

试试这个

您可以使用 Touch Listener 来做到这一点.

You can use Touch Listener to do this.

试试:

Handler handler = new Handler();
    b.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View arg0, MotionEvent arg1) {
            switch (arg1.getAction()) {
            case MotionEvent.ACTION_DOWN:
                handler.postDelayed(run, 5000/* OR the amount of time you want */);
                break;

            default:
                handler.removeCallbacks(run);
                break;

            }
            return true;
        }
    });

其中 b 是您想要长按的 view(在您的情况下它应该是按钮).

Where b is the view (in your case it should button) on which you want to make long click.

和Runnable run如下

Runnable run = new Runnable() {

    @Override
    public void run() {
        // Your code to run on long click

    }
};

希望它会有所帮助... :)
