将微调器设置为片段 [英] Setting spinners in fragment

问题描述

我正在尝试从我的 public最终类手册中的 onCreateView 中的一个片段中的字符串Array设置微调器的值:

I am trying to set the values for my spinner from a string Array in one of my fragments in the onCreateView in my 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，但是它没有设置微调器.微调框保持空白，没有任何值.为什么我的代码没有设置微调器?

I get no errors with my code, however it doesn't set the spinner. The spinner remains blank with no values. Any ideas on why my code isn't setting the spinner?

推荐答案

问题是我正在返回一个新视图，而不是我设置的视图.我不得不 return v; ，它工作正常.

The problem was I was returning a new view, not the one I set. I had to return v; and it worked fine.

@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;

}
