首先新建一个XXAdapter文件

package com.example.app.ui.win;

import android.app.Activity;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

import com.example.app.model.ThingType;

import java.util.List;

public class ThingTypeSpinnerAdapter extends BaseAdapter {
    private List<ThingType> tts;
    private Activity activity;
    public ThingTypeSpinnerAdapter(List<ThingType> tts, Activity activity){
        this.tts = tts;
        this.activity = activity;
    }
        @Override
        public int getCount() {
            return tts.size();
        }

        @Override
        public Object getItem(int i) {
            return null;
        }

        @Override
        public long getItemId(int i) {
            return 0;
        }

        @Override
        public View getView(int i, View view, ViewGroup viewGroup) {
            TextView textView = new TextView(activity);
            textView.setText(tts.get(i).getType());
            textView.setTextSize(18);
            return textView;
        }
}

List<ThingType> list = GsonUtil.toList(result.getString("data2"), ThingType.class);
BaseAdapter adapter=new XXAdapter(list,getActivity());
thingtype.setAdapter(adapter);
                            thingtype.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                                @Override
                                public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
                                    thingtypeId=list.get(i).getId();
                                    Toast.makeText(getActivity(),"你选择的是"+list.get(i).getId().toString(),Toast.LENGTH_SHORT).show();
                                }

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

                                }
                            });
