那么，有没有办法使用InjectView的片段？我知道，我可以用findViewbyId找到每一个元素，但我宁愿使用InjectView

 公共类ProfileFragment扩展RoboDialogFragment {

    @InjectView（R.id.commentEditText）
    受保护的EditText commentEditText;

    @覆盖
    公共无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;

            //我在这里得到一个空指针异常
            commentEditText.setText（有些评论）;

    }

    @覆盖
    公共查看onCreateView（LayoutInflater充气，容器的ViewGroup，捆绑savedInstanceState）{
        查看查看= inflater.inflate（R.layout.profile，集装箱，假）;

            //我在这里得到一个空指针异常
        commentEditText.setText（有些评论）;

        返回查看;
    }

}
 

解决方案

在注射过程中 onViewCreated

  @覆盖
公共无效onViewCreated（查看视图，捆绑savedInstanceState）{
    super.onViewCreated（查看，savedInstanceState）;

    commentEditText.setText（有些评论）;
}
 

I have a fragment that I need to display on the screen. I want to be able to use InjectView to inject my UI elements. InjectView works fine on activities because the view (xml) is set during onCreate, however on fragments the view is set on onCreatView.

So is there a way to use InjectView on fragments? I know that I could use findViewbyId to find each element, but I rather use InjectView

public class ProfileFragment extends RoboDialogFragment {

    @InjectView(R.id.commentEditText)
    protected EditText commentEditText;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

            // I get a  null pointer exception here
            commentEditText.setText("Some comment");

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.profile , container, false);

            // I get a  null pointer exception here
        commentEditText.setText("Some comment");

        return view;
    }

}

Injection happens during onViewCreated

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    commentEditText.setText("Some comment");
}
