我正在尝试添加到classpath外部库(这一个).我这样做的方式:File -> Project Structure -> Dependencies tab -> Add file dependency.那是对的吗？Maven的库列表没有Xstream.如果我点击add module dependency列表是空的.

所有我需要的是3个jar文件添加到类路径- xstream1.4.7.jar,xmlpull-1.1.3.1.jar和xpp3_min-1.1.4c.所以我按照以前写的那样做了.事情是,在此之后,我可以包括这个库,一切似乎都好.但在运行项目后出现错误:

    Error:Execution failed for task ':gridview:dexDebug'.

我是Android新手,因此遇到了这样的问题.

如何更改布局:

至:

XML fragment_main:

<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="com.example.snbgearassistant.MainActivity$PlaceholderFragment" >


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

</RelativeLayout>

所以我需要这些标签具有不同内容的网格布局.
