How to make FullScreen Activity on Android

Question

So, I'm trying to reproduce the appearance of the Muzei Live Wallpaper application from Roman Nurik, which is open source.

(Check out his GitHub repository here - https://github.com/romannurik/muzei/ )

When the application starts, a subtle SVG trace animation appears in the background, as well as the Ken Burns effect.

You may notice that the activity goes to the status bar and navigation bar.

I managed to achieve background animation, but I could not figure out how to make the exercise full-screen, as shown in the second GIF below.

I need help to make this action fullscreen / erase in the status bar and navigation bar.

That's what I was able to achieve.

MainActivity.Java

package devexchanges.info.kenburnview;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.Window;
import android.view.WindowManager;
import android.view.animation.AccelerateDecelerateInterpolator;
import android.widget.Toast;

import com.flaviofaria.kenburnsview.KenBurnsView;
import com.flaviofaria.kenburnsview.RandomTransitionGenerator;
import com.flaviofaria.kenburnsview.Transition;


public class MainActivity extends AppCompatActivity {

    private KenBurnsView kenBurnsView;
    private boolean isPlay = true;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        kenBurnsView = (KenBurnsView) findViewById(R.id.image);


        AccelerateDecelerateInterpolator ACCELERATE_DECELERATE = new AccelerateDecelerateInterpolator();
        RandomTransitionGenerator generator = new RandomTransitionGenerator(11000, ACCELERATE_DECELERATE);
        kenBurnsView.setTransitionGenerator(generator); //set new transition on kenburns view

        kenBurnsView.setTransitionListener(onTransittionListener());

    }

    private KenBurnsView.TransitionListener onTransittionListener() {
        return new KenBurnsView.TransitionListener() {

            @Override
            public void onTransitionStart(Transition transition) {
                //Toast.makeText(MainActivity.this, "start", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onTransitionEnd(Transition transition) {
                //Toast.makeText(MainActivity.this, "end", Toast.LENGTH_SHORT).show();
            }
        };
    }
}

Just add this to your method onCreate():

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN);

Answer 5

Just add this code to your onCreate () activity

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

Answer 6

use @ style / Theme.AppCompat.Light.NoActionBar if you use the AppCompat action

 <activity android:name=".view.activity.SplashActivity"
                  android:theme="@style/Theme.AppCompat.Light.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>

Answer 7

You can do this programmatically:

public class ActivityName extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // remove title
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
    }
}
