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 = (ViewHoller) convertView.getTag();
}
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);
}
}
