我正在尝试在Android 2.2项目中使用GridLayout,并在我的工作区中安装了gridlayout_v7项目后,将其添加到我的项目Android Dependencies中,为其自定义属性添加自定义xmlns,并将其嵌入到我的xml中布局如此:
<android.support.v7.widget.GridLayout
android:layout_width="match_parent"
android:layout_height="300dp"
grid:columnCount="2"
grid:rowCount="3" >
<include
android:layout_width="match_parent"
android:layout_height="match_parent"
layout="@layout/quick_contact" />
<include
android:layout_width="match_parent"
android:layout_height="match_parent"
layout="@layout/quick_contact" />
<include
android:layout_width="match_parent"
android:layout_height="match_parent"
layout="@layout/quick_contact" />
<include
android:layout_width="match_parent"
android:layout_height="match_parent"
layout="@layout/quick_contact" />
<include
android:layout_width="match_parent"
android:layout_height="match_parent"
layout="@layout/quick_contact" />
<include
android:layout_width="match_parent"
android:layout_height="match_parent"
layout="@layout/quick_contact" />
</android.support.v7.widget.GridLayout>
我在运行时开始收到以下异常:
java.lang.ClassNotFoundException: Didn't find class
"android.support.v7.widget.GridLayout" on path: DexPathList[[zip file
"system/framework/android.test.runner.jar", zip file "data/app/<app package>.apk"],
nativeLibraryDirectories=[data/app-lib/<app package>, /vendor/lib, /system/lib]]
我已经尝试过清理和重建,删除库并再次添加它但无济于事。 关于可能导致这种情况的任何想法?
答案 0 :(得分:1)
我看到了这个错误。对我来说,我必须在我的依赖项中特别包含网格布局,如下所示:
dependencies {
...
compile 'com.android.support:gridlayout-v7:18.0.+'
}
