Android应用程序在旋转时崩溃
Android应用程序在旋转时崩溃
提问于 2012-09-25 15:31:02
我将以下代码放入我的manifest.xml中
<activity android:name="CPohonApp" android:configChanges="keyboardHidden|orientation"></activity>这是我的活动中的代码
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
}但当我旋转时，应用程序仍然会崩溃。
这一切为什么要发生？
我使用Android 2.3.3 API 10
谢谢

你应该点(.)前导您的活动名称。
<activity android:name=".CPohonApp" android:configChanges="keyboardHidden|orientation"></activity>或者，当您在android清单文件中声明活动名称时，请使用全包名称。
<activity android:name="yourpackagename.CPohonApp" android:configChanges="keyboardHidden|orientation"></activity>Stack Overflow用户

在每个活动标签中使用
<activity android:name=".example" android:configChanges="orientation|keyboardHidden"/>Stack Overflow用户

<activity
android:name=".your activity"
