Android：删除白色启动屏幕

Question

我已经尝试实现启动画面以删除那个白色的启动屏幕，但我仍然在那里找到它。如何使用不同颜色更改白色启动屏幕或让我的启动画面显示白色启动屏幕？

的AndroidManifest.xml

  <activity
    android:name=".SplashActivity"
    android:theme="@style/SplashTheme"
    android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
  </activity>

值/ styles.xml

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:statusBarColor">@color/blue</item>
    <item name="android:windowDisablePreview">true</item>
        <!-- Customize your theme here. -->
    </style>
    <style name="SplashTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowBackground">@drawable/background_splash</item>
    <item name="android:statusBarColor">@color/blue</item>
    <item name="android:windowDisablePreview">true</item>

    </style>
