我在许多应用程序的模拟器中得到“不幸的应用已停止”错误。所有应用程序都可以使用与我在此处提到的相同的logcat.java文件。请发布解决方案。谢谢......... ..
这是我的清单文件：

答案 0 :(得分：3)
Caused by: java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'
您的R.layout.activity_main资源不包含ListView属性为android:id的{{1}}。这是android.R.id.list的要求。
答案 1 :(得分：0)
您正在使用listactivity并且错误表示您的活动中没有listview，ID为r.id.list
答案 2 :(得分：0)
为什么需要声明 LV = getListView（）; findViewbyId语句将listview从xml分配给Listview。 确保您的activity_main中声明了Listview，其ID为：“@ + id / list”。
