我試圖在Android中運行一個項目,但它試圖執行它時崩潰:我真的不明白我得到的logCat消息,所以我想看看是否有人可以幫助我在瞭解他們。項目上的Android logcat錯誤
下面是我的一些錯誤:
FATAL EXCEPTION: MAIN
java.lang.RunTimeException: Unable to start activity componentInfo (com.example.logger/com.example.logger.ThirdActivity):java.lang.RuntimeException: your content must have a ListView whose id attribe is 'android.R.id.list';
