如何修复Unable在android中启动活动ComponentInfo，android.view.InflateException

Question

我正在开发一个包含模拟量表视图的Android应用程序，当我在eclipse中导入该库并且项目成功运行时，我发现它here。当我将该库包含到我的项目中时，它不接受它。在库文件旁边显示一个红色十字标记，我的应用程序崩溃显示： - 无法启动活动ComponentInfo {com.example.c1test / com.example.c1test .Test}：android.view.InflateException 我也尝试以JAR文件的形式添加库但是它没有用，请帮助我，我正在处理它，因为四个小时请帮助我。这是我的xml：

Answer 1

以下行包含错误：

<com.example.libraryforvoltmeter
       android:id="@+id/gauge_view1"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_alignParentRight="true"
       android:layout_weight="1" />

可能是libraryforvoltmeter类不在以下包中：com.example 更改放置该库类文件的包
