创建的Android虚拟设备未显示

Question

我在Android Studio中创建了一个AVD但是当我进入layout-＆gt; activity_main.xml时它没有显示。错误消息显示如下。

Failed to create Context 0x3005
could not get wglGetExtensionsStringARB
emulator: WARNING: Could not initialize OpenglES emulation, using software renderer.
could not get wglGetExtensionsStringARB
could not get wglGetExtensionsStringARB

could not get wglGetExtensionsStringARB
emulator: emulator window was out of view and was recentered
Could not initialize emulated framebuffer

在activity_main.xml下有两个文件：activity_main.xml和activity_main.xml（土地）。在右侧的“组件树”和“属性”空间下，它显示＆＃34;无需显示＆＃34;。

当我尝试渲染它时，它会显示以下错误消息：

渲染问题渲染期间引发的异常：action_bar

xml文件如下所示：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"    
    android:layout_width="match_parent"
    android:layout_height="match_parent" 
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"    
    tools:context=".MainActivity">

    <TextView android:text="@string/hello_world"      
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

</RelativeLayout>

有什么想法吗？

哦，我想出了问题。我将 Android版本更新为用户时，将IDE中的布局从最佳选择更改为版本21，该版本位于显示框上方的AppTheme和MainActivity旁边。
