After button is pushed, execute these code. The codes inside "try" means jumping exactly to your targeted live wall paper but not the gallery of all of your live wallpapers. It seems fulfilled your requirement but it just works for >android 4.1.

The codes inside "catch" means jumping to the gallery of all of your live wallpapers if the phone doesn't support the code in "try".

Hopefully, it could help you :)

try{
       Intent intent = new Intent(WallpaperManager.ACTION_CHANGE_LIVE_WALLPAPER);
       intent.putExtra(WallpaperManager.EXTRA_LIVE_WALLPAPER_COMPONENT,
        new ComponentName(MainActivity.this, com.abc.YourMainProgram.class));
       startActivity(intent);
}
catch(Exception e){
        Intent intent = new Intent();
        intent.setAction(WallpaperManager.ACTION_LIVE_WALLPAPER_CHOOSER);
        startActivity(intent);
}

Use this in your styles.xml:

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat">
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:colorBackgroundCacheHint">@null</item>
    <item name="android:windowShowWallpaper">true</item>
    <item name="android:windowTranslucentNavigation">true</item>
    <item name="android:windowTranslucentStatus">true</item>
</style>
