这个问题是Android 版本的适配问题；

android 8.0 (API=26) 适配遇到的两个问题

解决方法：有两种，根据需求选择其一，或者两个一起用也行

（横屏方向问题）

（1）去掉android:screenOrientation；

（主题样式）
（2）android:windowIsTranslucent 改为false; 如果需要透明的设置加上android:windowDisablePreview =true；

在项目res目录下创建values-v26/styles.xml；

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="AppTheme.Splash" parent="AppTheme">
        <item name="android:windowActionBar">false</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowFullscreen">true</item>
      
        <!-- 适配android手机系统8.0(api26)，Only fullscreen opaque activities can request orientation -->
        <!--用背景图消除启动白屏-->
        <item name="android:windowBackground">@mipmap/qhao</item>
        <item name="android:windowIsTranslucent">false</item>
        <item name="android:windowDisablePreview">true</item>
    </style>
</resources>
