### Java类进行列表项内容的添加 ###

import android.content.Context;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.BaseAdapter;
    import android.widget.TextView;
    
    public abstract class MyAdapter extends BaseAdapter {
        private Context context;
        public MyAdapter(Context context){
            this.context = context;
        }
    
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            ViewHoller v;
            if(convertView==null){
                v = new ViewHoller();
                convertView = LayoutInflater.from(context).inflate(R.layout.items, null);
                v.mTvNo = (TextView) convertView.findViewById(R.id.tvNo);
                v.mTvAmount = (TextView) convertView.findViewById(R.id.tvAmount);
                v.mTvState = (TextView)convertView.findViewById(R.id.tvState);
                v.mTvTime = (TextView)convertView.findViewById(R.id.tvTime);
                v.mTvOperate = (TextView)convertView.findViewById(R.id.tvOperate);
                convertView.setTag(v);
    
            }else{

            }
            v.mTvNo.setText("201508281043");
            v.mTvAmount.setText("168");
            v.mTvState.setText("已发货");
            v.mTvTime.setText("2015-08-28 10:43");
            v.mTvOperate.setText("");
    
            return convertView;

        class ViewHoller{
            TextView mTvNo,mTvAmount,mTvState,mTvTime,mTvOperate;
        }
    }

### 加载列表项 ###

import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.widget.ListView;
    
    public class QueryShopping extends AppCompatActivity {
    private ListView mlistView;
    private MyAdapter myAdapter;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_query_shopping);
    
            mlistView = (ListView)findViewById(R.id.listView1);
        }
    }
