</RelativeLayout>

3、AddressAdapter.java

import java.util.ArrayList;
import java.util.List;

/**
 * 地址Adapter
 * Created by dwen on 2018/3/30.
 */

public class AddressAdapter extends BaseAdapter {

    List<AddressModel> addressList = new ArrayList<AddressModel>();
    Context context;

    public AddressAdapter( Context context,List<AddressModel> addressList) {
        this.addressList = addressList;
        this.context = context;
    }

    @Override
    public int getCount() {
        return this.addressList.size();
    }

    @Override
    public Object getItem(int position) {
        return this.addressList.get(position);
    }

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final ViewHolder holder;
        AddressModel addressModel = addressList.get(position);
        if (null == convertView){
            convertView = LayoutInflater.from(context).inflate(R.layout.item_address,null);
            holder = new ViewHolder(convertView);
            holder.txtDefault = convertView.findViewById(R.id.item_address_txt);
            holder.txtName = convertView.findViewById(R.id.item_address_name);
            holder.txtPhone = convertView.findViewById(R.id.item_address_phone);
            holder.txtAddress = convertView.findViewById(R.id.item_address);
            //TODO 须判断 是否显示隐藏"默认"
            holder.txtDefault.setText("[默认]");
            holder.txtName.setText(addressModel.getName());
            holder.txtPhone.setText(addressModel.getPhone());
            holder.txtAddress.setText(addressModel.getAddress());
            convertView.setTag(holder);
        }else{
            //直接通过holder获取子控件，不必使用findviewbyid，加快了 UI 的响应速度
            holder = (ViewHolder) convertView.getTag();
            //TODO 须判断 是否显示隐藏"默认"
            holder.txtDefault.setText("[默认]");
            holder.txtName.setText(addressModel.getName());
            holder.txtPhone.setText(addressModel.getPhone());
            holder.txtAddress.setText(addressModel.getAddress());
        }
        return convertView;
    }

    /**
     * ViewHolder save view and speed UI
     */
    static class ViewHolder{
        TextView txtDefault,txtName,txtPhone,txtAddress;

        public ViewHolder() {

        }

        public ViewHolder(View view) {

        }
    }
}

4、AddressListActivity.java

import java.util.ArrayList;
import java.util.List;

/**
 * 收货地址
 * Created by dwen on 2018/3/30.
 */

public class AddressListActivity extends BaseActivity {

    private List<AddressModel> addressList = new ArrayList<>();
    private ListView listView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_address_list);
        this.initAddressList();
        listView = (ListView) findViewById(R.id.address_list_view);
        AddressAdapter adapter = new AddressAdapter(AddressListActivity.this,addressList);
        listView.setAdapter(adapter);

    }

    /**
     * test address
     */
    private void initAddressList(){
        AddressModel model = new AddressModel();
        model.setIsDefault(1);
        model.setName("测试001");
        model.setPhone("13900000000");
        model.setAddress("湖南省长沙市湖南省长沙市");
        addressList.add(model);
        AddressModel model2 = new AddressModel();
        model2.setIsDefault(1);
        model2.setName("测试002");
        model2.setPhone("13900000000");
        model2.setAddress("湖南省长沙市湖南省长沙市");
        addressList.add(model2);
        AddressModel model3 = new AddressModel();
        model3.setIsDefault(1);
        model3.setName("测试003");
        model3.setPhone("13900000000");
        model3.setAddress("湖南省长沙市湖南省长沙市");
        addressList.add(model3);
        AddressModel model4 = new AddressModel();
        model4.setIsDefault(1);
        model4.setName("测试004");
        model4.setPhone("13900000000");
        model4.setAddress("湖南省长沙市湖南省长沙市");
        addressList.add(model4);
        AddressModel model5 = new AddressModel();
        model4.setIsDefault(1);
        model4.setName("测试005");
        model4.setPhone("13900000000");
        model4.setAddress("湖南省长沙市湖南省长沙市");
        addressList.add(model4);

    }
}
