在片段中设置微调器

Question

我想设置为从字符串数组我的微调值在我的一个片段 onCreateView在我的public final class Manual extends Fragment:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.manual, container, false);

    String [] values = 
        {"Time at Residence","Under 6 months","6-12 months","1-2 years","2-4 years","4-8 years","8-15 years","Over 15 years",};
    Spinner spinner = (Spinner) v.findViewById(R.id.spinner1);
    ArrayAdapter<String> LTRadapter = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_spinner_item, values);
    LTRadapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
    spinner.setAdapter(LTRadapter);

    return inflater.inflate(R.layout.manual, container, false);

}

我的代码没有错误,但它没有设置微调器.微调器保持空白,没有值.关于为什么我的代码没有设置微调器的任何想法？

Answer 1

问题是我正在返回一个新视图,而不是我设置的视图.我必须return v;,它工作得很好.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.manual, container, false);

    String [] values = 
        {"Time at Residence","Under 6 months","6-12 months","1-2 years","2-4 years","4-8 years","8-15 years","Over 15 years",};
    Spinner spinner = (Spinner) v.findViewById(R.id.spinner1);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_spinner_item, values);
    adapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
    spinner.setAdapter(adapter);

    return v;

}
