Android：如何获取Bunle Key

Question

我无法想象如何获得下面的条件方法＆amp; / Toast消息的Bundled Key。

我的学习经历将非常感谢任何帮助。日Thnx。

public class ListViewFragment extends ListFragment implements OnItemClickListener {
    private final String KEY_ADPTR_ID = "KEY_ADPTR_ID";
}

@Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState):

        Bundle args = this.getArguments();
        args.getString(KEY_ADPTR_ID);
        . . .
    }
. . .
    private void showData(String json) throws JSONException {

        String adptrID = this.getBundle(KEY_ADPTR_ID);//<-HOW DO I ACCOMPLISH THIS CORRECTLY!!??

        Toast.makeText(getActivity(), adptrID, Toast.LENGTH_SHORT).show();

        if (adptrID == "3") {
           . . .
        }
    }

如果您在片段的参数中传递KEY_ADPTR_ID，那么您在onActivityCreated中所写的内容是正确的

Bundle args = this.getArguments();
String keyAdaptrId = args.getString(KEY_ADPTR_ID);
