发布您的xml，也许是'Activity'的'onCreate（）'。我也会尝试清理你的项目 – codeMagic

膨胀XML时出现错误。在这里发布XML。 –

发表活动代码。 –

看来，你已经为

 <button 
     android:layout_width="fill_parent" 
     .......... 

        />

定义的XML布局内，您的按钮，但你必须写a capital b

 <Button 
     android:layout_width="fill_parent" 
     ............ 

        />

这就是内部错误信息所说的内容

Caused by: android.view.InflateException: Binary XML file line #15: Error inflating class button <--- You wrote button, but it has to be Button
