我使用两种样式制作了一个启动屏幕，第一种是默认样式，没有“windowBackground”，第二种是带有“窗口背景”的splash屏幕样式。问题是，当我使用getApplication().setTheme在MainActivity中使用下面的代码更改样式时：
@Override
protected final void onCreate(@Nullable Bundle savedInstanceState) {
// this line of code is not changing theme
getApplication().setTheme(R.style.Theme_Defaults);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);启动屏幕不会消失(“windowBackground”不会从“SpScreen”样式中删除)
宣言：
<application
android:hardwareAccelerated="true"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/SpScreen"
android:usesCleartextTraffic="true"
android:largeHeap="true"
android:extractNativeLibs="false"
tools:ignore="UnusedAttribute">Theme.xml:

<item name="android:allowGameAngleDriver" tools:ignore="NewApi">true</item>
<item name="android:windowBackground">@drawable/backgroud_splashscreen</item>
</style>两种风格的唯一区别是：
<item name="android:windowBackground">@drawable/backgroud_splashscreen</item>回答 1

而不是：
getApplication().setTheme(R.style.Theme_Defaults);试着使用：
getLayoutInflater().getContext().setTheme(R.style.Theme_Defaults);这应该能行。
