带有导航抽屉的 Android 微调器

Question

如何在此处添加微调器？实际上这是一个带有导航抽屉的项目。

public class ListViewFragment extends Fragment implements OnItemSelectedListener{
public ListViewFragment(){}

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

    return rootView;
}
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position,
        long id) {

}

@Override
public void onNothingSelected(AdapterView<?> arg0) {

}
}

我应该在哪里添加它？

Answer 1

public class ListViewFragment extends Fragment implements OnItemSelectedListener{
public ListViewFragment(){}
Spinner mspinner; //declare spinner globally
ArrayAdapter<String> adapter;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_listview, container, false);

mspinner        = (Spinner) view.findViewById(R.id.spinner1);

List<String> list = new ArrayList<String>();
list.add("list 1");
list.add("list 2");
list.add("list 3");
adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,list);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mspinner.setAdapter(dataAdapter);

return rootView;
}
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position,
    long id) {

//do something when particular item is selected from spinner

}

@Override
public void onNothingSelected(AdapterView<?> arg0) {

}
}
