安卓開發，點擊實現第三方接口事件
代碼塊：
public class MainActivity extends ActionBarActivity implements OnClickListener{
?private ImageButton imgBt;
?@Override
?protected void onCreate(Bundle savedInstanceState) {
??super.onCreate(savedInstanceState);
??setContentView(R.layout.main);
??imgBt = (ImageButton) findViewById(R.id.imageButton1);
??
??imgBt.setOnClickListener(this);
??
?}
?@Override
?public void onClick(View v) {
??Log.i("tag", "第三方實現類被實現了");
?}
?
控制臺顯示如下：

setContentView(R.layout.main);
檢查你的XML布局文件名是不是main.xml，默認不是這個文件名，除非你改過

給你百度了一下 好像是你的androidmainfest.xml有兩個ACTIVITY沖突了 你看下name是否一樣了吧
