问题：

登录成功后不上传MainActive（登录活动）Android Studio

我正在用android编程。当我使用（LoginActivity）成功登录时，下一步是加载MainActivity，这个MainActivity是一个导航抽屉活动，但我遇到了这个错误：

致命异常：主进程：com.example.administrador.vicon，PID：32149java.lang.运行时异常：无法启动活动ComponentInfo{com.example.administrador.vicon/com.example.administrador.vicon.MainActivity}：java.lang.IllegalStateException：此活动已经有一个由窗口装饰提供的操作栏。不要请求窗口。FEATURE_SUPPORT_ACTION_BAR并将主题中的windowActionBar设置为false以使用工具栏。

注意：loggin工作得很好，唯一的问题是没有上传mainactivity。

我有以下文件：

AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.administrador.vicon">
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>

        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

使用下面的项目或复制所有这些在您的styles.xml

<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>
