安卓顯示啓動畫面同時加載，但得到的黑色屏幕而不是

Question

我是從這個問題，試圖建議＃2： Android display Splash-Screen while loading

這是使用一個主題，然後一個背景繪製從Splash.java加載MainActivity它使用所述主題在MainActivity處理和加載時顯示圖像。

我得到一個黑屏幾秒鐘，然後主屏幕出現在第一次加載。

我錯過了什麼嗎？或者這個工作正常嗎？如果它工作正常，如果可能，我如何獲取圖像而不是黑屏？

我不得不在風格主題添加父得到它的工作。感謝您在Redman ^^^^評論中的鏈接。

EX：

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

Answer 2

我認爲你的Flash屏幕沒有加載，因爲你沒有設置任何閃屏時間。
嘗試打擊代碼：

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; 
}

//這是爲我工作。 //這是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(); 
    } 

} 

//這是我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>
