解决方法：在需要侧滑的 Activity 添加一个 Theme

  <!-- Base application theme. -->  <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">    <!-- Customize your theme here. -->    <item name="colorPrimary">@color/colorPrimary</item>    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>    <item name="colorAccent">@color/colorAccent</item>  </style>

  <style name="AppBackTheme" parent="@style/AppTheme">    <item name="android:windowIsTranslucent">true</item>  </style>

对activity添加theme

    <!-- 侧滑返回 -->    <activity      android:theme="@style/AppBackTheme"      android:name=".BackActivity">    </activity>
