Custom Progress bar with timer

Generally we use this splash screen to make our app dynamic and stylish.We can also use to show some process is doing internally. For this we just customize ProgressBar by defining custom style .

<progressbar 

android:id="@+id/splash_progress_bar" 
 style="@style/CustomProgressBar" 
android:layout_width="150dp" 
android:layout_height="wrap_content" 
android:layout_margin="5dp" 
android:max="100" 
android:progress="10" 
android:secondaryprogress="0">

Its the Custom style that we have to define:

style name="CustomProgressBar" parent="android:Widget.ProgressBar.Horizontal">
       < item name="android:indeterminateOnly">false
       <item name="android:progressDrawable">@drawable/custom_progress_bar_horizontal
       < item name="android:minHeight">5dip
       <item name="android:maxHeight">10dip
    /style>

In drawable folder create a xml custom_progress_bar_horizontal.

layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background">
       <shape>
            <corners android:radius="5dip">
            <gradient android:startcolor="#ffffffff" android:centercolor="#ffdddddd"

    </item>
    <item android:id="@android:id/secondaryProgress">
        <clip>
            <shape>
                <corners android:radius="5dip">
                <gradient android:startcolor="#770e75af" android:endcolor="#771997e1" android:angle="90">
            </gradient>
        </clip>
    </item>
    <item android:id="@android:id/progress">
        <clip>
            <shape>
               <corners android:radius="5dip">
                <gradient android:startcolor="#0000FF" android:endcolor="#0000FF" android:angle="90">
            </gradient></corners></shape>
        </clip>
    </item>
</layer-list>

Now apply it to your Activity

public class SplashActivty extends ActionBarActivity {
    private int timeToWaitInSec = 5;
    private int updateProgressBarInterval = 50;
    private CountDownTimer mCountDownTimer;
    private ProgressBar mprogressBar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mprogressBar = (ProgressBar) findViewById(R.id.splash_progress_bar);
        initAndRunCountDownTimer();
    }

/**
 * CountDownTimer for 5 sec wait.
 * on each tick update the Progress bar.
 */
private void initAndRunCountDownTimer() {
    mCountDownTimer = new CountDownTimer(1000 * timeToWaitInSec,
            updateProgressBarInterval) {
        int increment;

        @Override
        public void onFinish() {
            mprogressBar.setProgress(mprogressBar.getMax());
            //Call to another activity
        }

        @Override
        public void onTick(long millisUntilFinished) {
            increment = ((mprogressBar.getMax() * updateProgressBarInterval) / (1000 * timeToWaitInSec));
            mprogressBar.setProgress(mprogressBar.getProgress() + increment);
        }
    };
    mCountDownTimer.start();
}

}
