您可以创建一个接口,将适配器与活动进行通信 创建一个像
public interface AdapterComunication{
public void callBack();
}
然后让您的活动实现此接口
public class MainActivity extends ActionBarActivity implements AdapterComunication {
....
@Override
public void callBack() { .. }
}
然后让适配器接收
public AnggraListAdapter(AdapterComunication listener, List<AnggraList> list) {
this.listener = listener;
...
}
最后,在OnClickListener中,调用如下方法
listener.callback();
通过这种方式,您可以将值从适配器传递到活动,然后创建另一个活动,例如传递捆绑包
我希望这有帮助
listener.callback();
