Android display Splash-Screen while loading but getting black screen instead

Question

I'm trying suggestion #2 from this question: Android display Splash-Screen while loading

This is using a theme with a background drawable then loading MainActivity from Splash.java which uses said theme to display an image while MainActivity processes and loads.

I'm getting a black screen for several seconds then the main screen appears on first load.

Am I missing something? Or is this working correctly? If it's working correctly, how do I get an image to show instead of the black screen if possible?

@drawable/background_splash

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Fill the background with a solid color -->
    <item
        android:drawable="@color/colorPrimary"/>
    <item>

        <!-- Place your bitmap in the center -->
        <bitmap
            android:gravity="center"
            android:src="@mipmap/ic_launcher"/>

I Think Your Flash Screen is not load because are you not set any time of splash screen.
Try blow code:

public class Splash extends Activity {

private CountDownTimer timer = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    timer = new CountDownTimer(2000, 1000) {

        @Override
        public void onTick(long millisUntilFinished) {

        }

        @Override
        public void onFinish() {
               Intent intent = new Intent(this, MainActivity.class);
               startActivity(intent);
               finish();
        }
    };
}

@Override
protected void onResume() {
    super.onResume();
    timer.start();
}

@Override
protected void onPause() {
    super.onPause();
    timer.cancel();
}

@Override
protected void onDestroy() {
    super.onDestroy();
    timer = null;
}

// This is working for me. // This is Splash.java

public class Splash extends ActionBarActivity
 {



    @Override
    protected void onCreate(Bundle savedInstanceState) {

         super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_splash);

            Thread th = new Thread() {
            public void run() {
                try {
                    sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                } finally {
                  // write your activity which you want to open

             Intent intent = new Intent(Splash.this, MainActivity.class);
                        startActivity(intent);
                        finish();

                }
            }
        };
        th.start();
    }

}

// and this is my Splash.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="@drawable/bk_client"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:gravity="center"
        android:layout_centerInParent="true">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/logo"
        android:layout_centerInParent="true"/>

      </LinearLayout>

</RelativeLayout>

Answer 3

I had to add a parent in the style theme to get it working. Thank you for the link in the comments Redman ^^^^.

EX:

<style name="SplashTheme"
    parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:background">@drawable/background_splash</item>
    <item name="android:windowAnimationStyle">@null</item>
</style>
