你把报错log贴出来....

抓log，在log里搜一下fatal就能看到错误位置

在你的AndroidManifest.xml文件中mainActivity的





添加

        变成：
        <intent-filter>
        <action android:name="com.example.deviceshow.MainActivity"/>
                    <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.DEFAULT" />
