为Android应用程序添加启动页

为 Android 应用程序添加启动页的步骤如下：

1. 用XML编辑器打开 “AndroidManifest.xml”，在文件里添加如下内容：

   <meta-data android:name="android.app.splash_screen_drawable" android:resource="@drawable/splash"/>

   • 其中“splash”就是程序启动页面的图片。添加后的文件结果大概如下：

   <?xml version="1.0"?>
   <manifest package="org.qtproject.example" xmlns:android="http://schemas.android.com/apk/res/android" android:versionName="1.0" android:versionCode="1" android:installLocation="auto">
       <application android:hardwareAccelerated="true" android:name="org.qtproject.qt5.android.bindings.QtApplication" android:label="-- %%INSERT_APP_NAME%% --" android:icon="@drawable/icon" android:theme="@style/MyAppTheme">
           <activity android:configChanges="orientation|uiMode|screenLayout|screenSize|smallestScreenSize|layoutDirection|locale|fontScale|keyboard|keyboardHidden|navigation" android:name="org.qtproject.qt5.android.bindings.QtActivity" android:label="-- %%INSERT_APP_NAME%% --" android:screenOrientation="unspecified" android:launchMode="singleTop">
               ...
   
               <!-- Splash screen -->
   
               <meta-data android:name="android.app.splash_screen_drawable" android:resource="@drawable/splash"/>
   
               <!-- Splash screen -->
   
               ....
           </activity>
       </application>
       <uses-sdk android:minSdkVersion="9" android:targetSdkVersion="14"/>
       <supports-screens android:largeScreens="true" android:normalScreens="true" android:anyDensity="true" android:smallScreens="true"/>
   
       <!-- The following comment will be replaced upon deployment with default permissions based on the dependencies of the application.
            Remove the comment if you do not require these default permissions. -->
       <!-- %%INSERT_PERMISSIONS -->
   
       <!-- The following comment will be replaced upon deployment with default features based on the dependencies of the application.
            Remove the comment if you do not require these default features. -->
       <!-- %%INSERT_FEATURES -->
   
   </manifest>

2. 分别在项目路径 “./android/res” 目录下 drawable-* 文件夹 （“drawable-ldpi”、“drawable-mdpi”和“drawable-hdpi”等）下添加一个“splash,png”图片，图片名称一定要和第一步的名称一样。
