Hi,

I need a busy indicator on the splash screen of Xamarin.Android app, because the launching van de app takes about 7 seconds.

Could you give me an example for this?

Thanks in advance!

Does the white screen show before the splash screen? If so, adding an indicator may not sovle this problem. You could display the indicator by setting contentView for the splash Activity, but the layout view will be shown after the white screen.

To remove the white screen, try adding the following setting for the theme style of the splash Activity.

<item name="android:windowFullscreen">true</item> <item name="android:windowContentOverlay">@null</item> <item name="android:windowIsTranslucent">true</item>

Hi Jarvan,

>Does the white screen show before the splash screen?

No.

the white screen is replaced by splashscreen.png.

The user waits 7 seconds with static splashscreen.png. It is a little boring.

That is why I want to add a busy indicator (ring / process bar) to splashscreen.

An animated image is also good.

Have you an example?

styles.xml

<?xml version="1.0" encoding="utf-8" ?>
<resources>
<style name="MyTheme.Splash" parent ="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowBackground">@drawable/splashscreen</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">@Null </item>
<item name="android:windowActionBar">true</item>
</style>
</resources>

Hello,

Welcome to our Microsoft Q&A platform!

The user waits 7 seconds with static splashscreen.png. It is a little boring.

You could create a layout file to display the progressbar. And then set contentView for the Splash Activity as a normal activity.

Here is a similar issue thread about setting a layout for the splash Activity, you could refer to it.
