1、ListView listview=findViewById(R.id.listview);
2、public class MyAdapter extends BaseAdapter{
private LayoutInflater myLayoutInflater =LayoutInflater.from(context);//用来绑定需要设定的Item.xml
public MyAdapter(){}//构造函数,传入值
public class Info {//存放每个listview中的控件
public TextView textview;
}
//再重写四个函数
@Override
public int getCount() {
return car_num_str.length;//返回需要展示多少个item
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
@Override//重点
public View getView(int position, View convertView, ViewGroup parent) {
Info info = null;
if (convertView == null) {
Info = new Info();
convertView = myLayoutInflater.inflate(R.layout.item, null);
info.textview = (TextView) convertView.findViewById(R.id.textview);
convertView.setTag(info);
} else {
info = (Info) convertView.getTag();
}
info.textview.setText(Stringtv[position]);//将外部传进来的车牌号放在listview中
return convertView;
}
}
3、MyAdapter myAdapter = new MyAdapter();//得到适配器对象
4、listview.setAdapter(myAdapter);//添加适配器
