Adapter 代码

package adpter;

import android.content.Context;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

import com.example.lenovo.myctriptest.R;

import tools.TrainCheCiBean;

public class TrainAdapter extends BaseAdapter{
Context context;
TrainCheCiBean trainBean;
public TrainAdapter(Context context,TrainCheCiBean trainBean){
this.context=context;
this.trainBean=trainBean;

@Override

    return 0;

@Override
public View getView(int i, View view, ViewGroup viewGroup) {
   view= View.inflate(context, R.layout.train_adapter,null);
    TextView text_code = view.findViewById(R.id.text_code);//站点序号
    text_code.setText(trainBean.getShowapi_res_body().getContext().get(i).get(0)+"");
    TextView text_start = view.findViewById(R.id.text_start);//站点名称
    text_start.setText(trainBean.getShowapi_res_body().getContext().get(i).get(1)+"");
    //到达时间
    TextView text_end = view.findViewById(R.id.text_end);

    text_train_start.setText(trainBean.getShowapi_res_body().getContext().get(i).get(4)+"");
