Set Duration of Long Key press Listener

Question

Can we set duration for Long key press listener? What i want is, if user keeps touching the screen for 3 sec then my long key press listener should trigger and open my pop up fo

Answer 1

Inside the Long Press Listener u can set a Handler with 3 Sec Limit and if it reaches 3 sec time then u can run your method in it or else make default method

Answer 2

From Android 2.0, Activity contains the method

public boolean onKeyLongPress(int keyCode, KeyEvent event)

For exemple, a long key press on the back button would be :

@override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) 
    {
        // do your stuff here
        return true;
    }
    return super.onKeyLongPress(keyCode, event);
}

Now to open the setting tab you can do following code inside and activity...

Intent intent = new Intent(android.provider.Settings.ACTION_SETTINGS);
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
activityContext.startActivity(intent);

Override onTouch Listener ,then handle pressed,released event and set timer during button pressed (event == "pressed")

private Timer timer;

 public LongClickTimer(int seconds) {
            timer = new Timer();
            timer.schedule(new LongClickTask(), seconds *1000);         
        }
 class LongClickTask extends TimerTask {
            public void run() { 
             // do what you want            
                timer.cancel(); 
            }
        }
     button.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                Log.v(TAG, "EVENT" + event.toString());
                    if(event.getAction == 2) {// pressed                        
                    new LongClickTimer(5); // schedule for 5 seconds
                    }else{          
                     timer.cancel();
                    }
               return false;
              }
           });
