布局代码:

bubuko.com,布布扣
<LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    </ListView>
    </LinearLayout>
bubuko.com,布布扣

 

错误信息:

E/AndroidRuntime(2728): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.*****.Main}:

java.lang.RuntimeException: Your content must have a ListView whose id attribute is ‘android.R.id.list‘
06-01 21:41:51.028: E/AndroidRuntime(2728): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java)

提示要使用android内置的id号:android.R.id.list

修改后的布局:

    <ListView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/android:list" >
    </ListView>
