Question

I have implemented button’s onLongClickListener in Android Dialog which auto-decreases number using timers. Here is the code

myIncreaseTimer = new Timer();
final Runnable runnable_decrease = new Runnable() {
    public void run() {
        int txt = Integer.parseInt(length.getText().toString());
        txt -= 1;
        length.setText(String.valueOf(txt));
        if (txt == 0) {
            myIncreaseTimer.cancel();
            myIncreaseTimer.purge();
            myIncreaseTimer = new Timer();
        }
    }
};
btnMinus.setOnLongClickListener(new View.OnLongClickListener() {
    public boolean onLongClick(View v) {
        myIncreaseTimer.schedule(new TimerTask() {
            @Override
            public void run() {
                runOnUiThread(runnable_decrease);
            }
        }, 0, 300);
        return true;
    }
});

When I am inside of activity, not dialog, I can stop the decrease via onTouchEvent when a user touches the screen

@Override 
public boolean onTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_UP) {
        myIncreaseTimer.cancel();
        myIncreaseTimer.purge();
        myIncreaseTimer = new Timer();
    }
    return true;
}

However, I cannot do this in the dialog. Even more, the dialog does not have onTouchEvent.

Does anyone know how can I either implement onTouchEvent in Dialog or where should I stop the increase timer in the Dialog?

Answer 1

You can’t handle onTouch on Dialog so

Create a Activity, implement onTouchListener on it,
and in manifest file

<activity android:theme="@android:style/Theme.Dialog">

So, now your activity is look like a DialogBox,
