Question

我在android中编程。当我使用（LoginActivity）记录sucessfull时，下一步是加载MainActivity，这个MainActivity是一个导航抽屉活动，但是我收到了这个错误：

致命的例外：主要处理：com.example.administrador.vicon，PID：32149 java.lang.RuntimeException：无法启动活动ComponentInfo {com.example.administrador.vicon / com.example.administrador.vicon.MainActivity}：java.lang.IllegalStateException：此Activity已经有一个由窗口装饰提供的操作栏。请勿在主题中请求Window.FEATURE_SUPPORT_ACTION_BAR并将windowActionBar设置为false以使用工具栏。

注意：登录工作完美，只有问题是不上传主要活动。

我有以下文件：

的AndroidManifest.xml

谢谢你的时间。

Answer 1

使用下面的项目或在styles.xml

中复制所有这些内容

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here.  -->

    <item name="windowActionBar">true</item>


</style>

或清单

<activity android:name=".MainActivity" android:theme="@style/AppTheme.NoActionBar" ></activity>

登录成功（LoginActivity）Android Studio后，无需上传MainActivity
