Android 如何对同一个按钮同时使用 OnClick 和长按(3 秒)

Question

在我的应用程序中，我需要做一些Action A，同时为按钮做正常的click，并且需要在按住同一按钮超过 3 秒的同时执行其他一些Action B。 我试过下面的代码

private boolean isMoved = false;
    final Runnable runr = new Runnable() {

                    @Override
                    public void run() {
                        // Your code to run on long click
                        System.out.println("long pressed for 3 sec");

                    }
                };

                final Handler handel = new Handler();
                contactButton.setOnTouchListener(new View.OnTouchListener() {

                    @Override
                    public boolean onTouch(View arg0, MotionEvent arg1) {
                        switch (arg1.getAction()) {
                        case MotionEvent.ACTION_DOWN:
                            isMoved = false;
                            handel.postDelayed(runr,3000);
                            break;          
                        case MotionEvent.ACTION_MOVE:
                            isMoved = true;

                        case MotionEvent.ACTION_UP:
                            if(!isMoved)
                                System.out.println("button single click");

                        default:
                            handel.removeCallbacks(runr);
                            break;

                        }
                        return true;

                    }
                });

但是它并没有像我期望的那样工作，任何人都请指导我完成这个操作。

所有回答和评论都是真实的。这是你的实现

Button button;
long down,up;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    button = (Button) findViewById(R.id.button);
    button.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View view, MotionEvent motionEvent) {
            switch (motionEvent.getAction()){
                case MotionEvent.ACTION_DOWN :
                    Toast.makeText(MainActivity.this, "Down", Toast.LENGTH_SHORT).show();
                    down=System.currentTimeMillis();
                    break;
                case MotionEvent.ACTION_UP :
                    Toast.makeText(MainActivity.this, "Up", Toast.LENGTH_SHORT).show();
                    up=System.currentTimeMillis();
                    if(up-down>3000)
                        Toast.makeText(MainActivity.this, "More than 3", Toast.LENGTH_SHORT).show();
                    return true;
            }
            return false;
        }
    });
}
