我在logcat中遇到的错误是：
08-03 04：49：03.828：E / AndroidRuntime（773）：java.lang.RuntimeException： 无法开始活动 ComponentInfo {} com.example./com.exampleMainActivity： java.lang.ClassCastException：com.example.MainActivity无法强制转换 到android.widget.AdapterView $ OnItemClickListener
但是现在logcat中没有消息，但msg仍然是：
不幸的是停止了工作。
当应用程序运行时，将从主活动中添加详细信息并单击“保存”按钮，它将以谷歌形式存储。 帮助我。
