Splash Activity

1.編輯 value/styles.xml 加入以下內容

<resources>  
  ...  
      <style name="AppTheme.Launcher">  
          <item name="android:windowBackground">@drawable/launch_screen</item>  
          <!-- Optional, on Android 5+ you can modify the colorPrimaryDark color to match the windowBackground color for further branding-->  
          <!-- <item name="colorPrimaryDark">@android:color/white</item> -->  
      </style>  
  ...  
  </resources>  
  

其中 @drawable/launch_screen 目前還沒有，下一步製作。

2.在 drawable 新增 launch_screen.xml，內容如下

<?xml version="1.0" encoding="utf-8"?>  
    
  <!-- The android:opacity="opaque" line — this is critical in preventing a flash of black as your theme transitions. -->  
  <layer-list xmlns:android="http://schemas.android.com/apk/res/android"  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:opacity="opaque">  
    
    <!-- The background color, preferably the same as your normal theme -->  
    <item android:drawable="@android:color/white"/>  
    
    <!-- Your product logo - 144dp color version of your app icon -->  
    <item>  
      <bitmap  
        android:gravity="center"  
        android:src="@drawable/your_logo"/>  
    </item>  
    
  </layer-list>

其中 @drawable/your_logo 就是你想顯示的 logo 圖示

3. SplashActivity

該 Activity 除了在 onCreate 作了特殊處理之外，並沒有其它不同。如下

public class LogoActivity extends Activity {  
  ...  
      
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
      setTheme(R.style.AppTheme);  
      super.onCreate(savedInstanceState);  
    }  
    
  ...

 

4. 在 AndroidManifest.xml 讓 LogoActivity 套用 AppTheme.Launcher

    <activity  
        android:theme="@style/AppTheme.Launcher"  
        android:name=".logo.LogoActivity">  
        <intent-filter>  
          <action android:name="android.intent.action.MAIN"/>  
    
          <category android:name="android.intent.category.LAUNCHER"/>  
        </intent-filter>  
      </activity>
