Android Studio-膨胀类EditText时出错

我一整天都在努力解决这个问题。我在Android Studio中创建了一个新项目，并选择了选项卡导航活动。从那里，我在fragment_main.XML的XML中添加了一个简单的EditText并运行它。它总是给我一个错误。任何其他元素（如TextView）都不会出现这种情况

fragment_main.xml：

<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:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="packagename.MainActivity$PlaceholderFragment">

    <TextView
        android:id="@+id/section_label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:inputType="textPersonName"
        android:text="Name"
        android:ems="10"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true"
        android:id="@+id/editText3" />
</RelativeLayout>

注意：我唯一更改的是在创建带有选项卡导航活动的项目后，向fragment_main.xml添加EditText。没有任何Java代码被更改。在你看到“包名”的地方，这实际上是我的完整包名，为了隐私，我刚刚删除了它

提前感谢

我最近也遇到了同样的问题。显然，问题在于Gradle 2.2-alpha*不知道如何正确处理

EditText

的九个补丁图像。尤其是位于

res/drawable-v21/abc\u edit\u text\u material.xml

中的一个。这是code.google中目前尚未解决的问题

解决方案很简单，现在只需将Gradle版本降级为

2.1

，而不是

2.2-alpha2

甚至

2.2-alpha3

。当我这样做的时候，它对我非常有效

干杯：）

missed>在根布局中我犯了错误，我在问问题时删除了包名，代码中有>。我已经编辑了问题清理并重建了项目应用程序仍然会因同样的错误而崩溃显示您的java文件代码谢谢，前一段时间通过降级解决了这个问题。我会接受你的回答：）
