我為我的 Android 游戲創建了一個啟影片面主題。但問題是我的啟影片面在 OnCreate(Bundle bundle) 完全執行后自動結束，這導致在執行 Draw(GameTime gameTime) 之前出現黑屏。我在 Draw(GameTime gameTime) 中繪制我的游戲精靈。因此，在執行 Draw(GameTime gameTime) 之前會出現黑屏。
當我的游戲代碼已經達到 Draw(GameTime gameTime) 時，是否可以手動結束啟影片面？我不希望在 OnCreate(Bundle bundle) 完全執行時啟影片面已經結束。

uj5u.com熱心網友回復：
是否可以使用我的 splash_screen_svg.xml 或 svg 檔案？
在 drawable 檔案夾中創建一個 splash_screen.xml。
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<color android:color="@color/splash_background"/>
</item>
<item>
<bitmap
android:src="@drawable/splash_logo"
android:tileMode="disabled"
android:gravity="center"/>
</item>
</layer-list>
在 Resources/values/colors.xml 中添加特定顏色。
<?xml version="1.0" encoding="utf-8"?>
<resources>
...
<color name="splash_background">#FFFFFF</color>
</resources>
在 Resources/values/styles.xml 中創建主題
<style name="Theme_SplashScreen" parent ="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowBackground">@drawable/splash_screen</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>
在 Activity_SplashScreen 活動中加載啟影片面。
[Activity(Label = "Activity_SplashScreen", Theme = "@style/Theme_SplashScreen", MainLauncher = true)]
public class Activity_SplashScreen : Activity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your application here
}
protected override void OnResume()
{
base.OnResume();
Task startupWork = new Task(() => { SimulateStartup(); });
startupWork.Start();
}
// Simulates background work that happens behind the splash screen
async void SimulateStartup()
{
await Task.Delay(3000); // Simulate a bit of startup work.
StartActivity(new Intent(Application.Context, typeof(Activity_Screen)));
}
}
Activity_Screen 活動：
[Activity(Label = "Activity_Screen")]
public class Activity_Screen : Activity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your application here
SetContentView(Resource.Layout.layout_Screen);
Toast.MakeText(this, "Welcome to MainActivity", ToastLength.Long).Show();
}
}
