Question

I have problem with my splash screen on Android. Splash screen is displayed to the user during long application startup but activity background is always black. I mean backg

Answer 1

This is how I was able to get white background splash (logo centred) in Xamarin.

[Activity (Theme= "@style/Theme.Splash", MainLauncher=true, NoHistory=true)]            
public class SplashActivity : Activity
{
    protected override void OnCreate (Bundle bundle)
    {
        base.OnCreate (bundle);
        SetContentView (Resource.Layout.splash);
        ThreadPool.QueueUserWorkItem (o => LoadActivity ());
        // Create your application here
    }
    private void LoadActivity() {
        Thread.Sleep (1000); // Simulate a long pause
        RunOnUiThread (() => StartActivity (typeof(MainActivity)));
    }
}

with Theme.Splash as:

<resources>
  <style name="Theme.Splash" parent="@android:style/Theme.Light">
    <item name="android:colorBackground">@android:color/white</item>
    <item name="android:windowNoTitle">true</item>
  </style>
</resources>

and splash.axml code (Theme.Light.NoTitleBar) as:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:minWidth="25px"
    android:minHeight="25px"
    android:gravity="center">
    <ImageView
        android:src="@drawable/splash"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/imageView1"
        android:layout_gravity="center" />
</LinearLayout>

NB: There is a slight delay in the splash png (logo) to come up, but its still acceptable, better than the black background.

In resources/drawable/splash_centered.xml, instead of the bitmap use a layer-list

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item>
    <shape android:shape="rectangle">
      <solid android:color="@android:color/white" />
    </shape>
  </item>
  <item>
    <bitmap android:gravity="center" android:src="@drawable/splash" />
  </item>
</layer-list>

Answer 3

set android:drawable="@color/colorWhite" to item.

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

    <item android:drawable="@color/colorWhite" />

    <item>
        <bitmap
            android:gravity="center"
            android:src="@drawable/splash" />
    </item>
</layer-list>
