我正在尝试在android studio中制作简单的SlidingPanel。 我在SDK管理器中下载了存储库(Google和支持),并通过添加以下行编辑了gradle文件:
compile 'com.android.support:support-v4:18.0.0'
compile 'com.android.support:appcompat-v7:18.0.+'
Libs在项目中可见。 我还添加了一个布局:
<android.support.v4.widget.SlidingPaneLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/main_layout"
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">
<include layout="@layout/fragment_menu_panel" android:layout_height="match_parent" android:layout_width="wrap_content"/>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ff333333" >
<WebView
android:id="@+id/content_text"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ProgressBar
android:id="@+id/progressBar1"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true" />
</RelativeLayout>
</android.support.v4.widget.SlidingPaneLayout>
它在IDE中呈现得相当不错,但是当我尝试在设备上运行此应用程序时,它会因以下错误而崩溃:

问题就我看到该库没有附加到apk。我该如何解决?
答案 0 :(得分:1)
这是一个非常奇怪的问题,无论如何修复了构建 - &gt;重建项目。 所以除了Android Studio之外,每件事都很好。
