android菜单的一个问题
为什么我在AndroidManifest.xml文件中声明的菜单项活动不起作用，在模拟器运行程序打开菜单，选中菜单项的时候报错，logtag里说我是在AndroidManifest.xml文件中没有声明，为什么啊! --------------------编程问答-------------------- 什么菜单要去AndroidManifest里？err log? --------------------编程问答-------------------- 不太明白楼主的意思，Menu, 只要重写一些方法就行了吧 --------------------编程问答-------------------- 菜单不需要到AndroidManifest.xml这里面去声明的。 --------------------编程问答-------------------- 就是按menu键出来的菜单选了菜单项之后程序终止，查了下错误说你在AndroidManifest.xml中声明了吗？，可我明明声明了啊！ --------------------编程问答-------------------- <activity android:name=".XXActivity">
检查下name属性是否正确设置了 --------------------编程问答-------------------- 这个菜单不需要声明吧。。楼主贴下代码或者log吧

--------------------编程问答-------------------- 菜单项点击事件去启动新的Activity了，要把这个Activity注册到Manifest里面，而不是注册菜单 --------------------编程问答-------------------- ActivityNotFoundException
activity没部署 --------------------编程问答-------------------- 9楼正解 --------------------编程问答-------------------- 我菜单里有个settings菜单项，点击启动的Activity我注册了啊，可是还是这样 --------------------编程问答-------------------- 09-07 02:52:02.351: ERROR/AndroidRuntime(724): android.content.ActivityNotFoundException: Unable to find explicit activity class {org.example.sudoku/android.provider.Contacts$Settings}; have you declared this activity in your AndroidManifest.xml?
很明显，没有找到相应的Activity,以前我有一次经历。就是我向eclipse中导入一个项目，明明是导入进去的，但是在我的工作目录下，就是没有。于是，我把该项目复制到我的工作目录中，然后再导入。这下就好了。有时会出现一些情况，不知道你是不是这种情况。 --------------------编程问答-------------------- 9楼的说的对 --------------------编程问答-------------------- 看看注册的代码有没有问题，我也遇到过这样的事但好像都是，没注册或代码有误…… --------------------编程问答-------------------- 晕死，原来是import里导入的类和活动冲突了，顺利解决了，谢谢大家！
