onKeyDown and onKeyLongPress

Here is the code that I wrote. It works like a charm. May be you can optimize it for better logic. But you will get the point with it. The key is to use flags. Short press is a press where we press volume button for short time and release. So onKeyUp is the one which will help us detect short presses.

package com.example.demo;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.KeyEvent;
import android.view.Menu;

public class TestVolumeActivity extends Activity {
    boolean flag = false;

    boolean flag2 = false;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash_screen);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_splash_screen, menu);
        return true;
    }

    @Override
    public boolean onKeyLongPress(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {
            Log.d("Test", "Long press!");
            flag = false;
            flag2 = true;
            return true;
        }
        return super.onKeyLongPress(keyCode, event);
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {
            event.startTracking();
            if (flag2 == true) {
                flag = false;
            } else {
                flag = true;
                flag2 = false;
            }

            return true;
        }
        return super.onKeyDown(keyCode, event);
    }

    @Override
    public boolean onKeyUp(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {

            event.startTracking();
            if (flag) {
                Log.d("Test", "Short");
            }
            flag = true;
            flag2 = false;
            return true;
        }

        return super.onKeyUp(keyCode, event);
    }
}

Logcat for all long presses(No short press detected):

10-18 02:06:15.369: D/Test(16834): Long press!
10-18 02:06:18.683: D/Test(16834): Long press!
10-18 02:06:21.566: D/Test(16834): Long press!
10-18 02:06:23.738: D/Test(16834): Long press!

Logcat for all short presses:

10-18 02:07:42.422: D/Test(16834): Short
10-18 02:07:43.203: D/Test(16834): Short
10-18 02:07:43.663: D/Test(16834): Short
10-18 02:07:44.144: D/Test(16834): Short
