错误提示： Caused by: java.lang.ClassCastException: com.example.cheung.sbulter.MainActivity cannot be cast to android.view.View.OnClickListener

问题描述：在安卓模拟上运行程序，程序闪退，显示：xx has stopped

                  提示：Caused by: java.lang.ClassCastException: com.example.cheung.sbulter.MainActivity cannot be cast to android.view.View.OnClickListener

解决办法：In MainActivity, you should implement View.OnClickListener. in this case, you don't need your own interface XXXXXXX.java, just use View.OnClickListener

                  that is to say, change   

                 public class MainActivity extends Activity implements onClickListener

                 to 

                public class MainActivity extends Activity implements View.OnClickListener

结果：已解决
