使用微调器值作为列表项的Android搜索列表视图

Question

我创建了一个列表视图，其中包含每个列表项上的微调器和单选按钮，并根据每个列表项上的微调器值创建了编辑文本以搜索列表视图项。

如何使用列表项中的微调器值实现搜索功能。

例如，当在编辑文本中输入1时，将列出包含在微调器中选择的1的所有列表项。

ListAdapter.java

public class ListAdapter extends ArrayAdapter<DataModel>
{
private Activity myContext;
int selectedPos = -1;
int flag = 0;
int pos = 0;

public ListAdapter(Activity context, int textViewResourceId, DataModel[] objects)
{
    super(context, textViewResourceId, objects);
    myContext = context;
}

static class ViewHolder
{
    protected DataModel data;
    protected TextView selectedText;
    protected Spinner spin;
    protected RadioButton radioBtn;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent)
{
    View view = convertView;
    final ViewHolder viewHolder;

    if (view == null)
    {
        LayoutInflater inflator = myContext.getLayoutInflater();
        view = inflator.inflate(R.layout.single_list_row, null);

        viewHolder = new ViewHolder();
        viewHolder.data = new DataModel(myContext);

        viewHolder.selectedText = (TextView) view.findViewById(R.id.singleitem);
        viewHolder.spin = (Spinner) view.findViewById(R.id.spinner1);
        viewHolder.spin.setAdapter(viewHolder.data.getAdapter());
        viewHolder.radioBtn = (RadioButton) view.findViewById(R.id.choice);

        view.setTag(viewHolder);
    }
    else
    {
        viewHolder = (ViewHolder) view.getTag();
    }

    viewHolder.spin.setOnItemSelectedListener(new OnItemSelectedListener()
    {
        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3)
        {
            viewHolder.data.setSelected(arg2);
            viewHolder.selectedText.setText(viewHolder.data.getText());
        }

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

    if(flag != 1)
    {
        if (selectedPos == position)
        {
            viewHolder.radioBtn.setChecked(true);
        }
        else
        {
            viewHolder.radioBtn.setChecked(false);
        }
    }
    else
    {
        viewHolder.radioBtn.setChecked(true);
    }

    viewHolder.radioBtn.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View view)
        {
            if(flag != 1)
            {
                if (((RadioButton) view).isChecked())
                {
                    selectedPos = position;
                }
                else
                {
                    selectedPos = -1;
                }
            }
            else
            {
                ((RadioButton) view).setChecked(true);
            }
            notifyDataSetChanged();
        }
    });
    viewHolder.selectedText.setText(viewHolder.data.getText());
    view.setTag(viewHolder);
    return view;
