AndroidTV 网络机顶盒 Wi-Fi设置

2019独角兽企业重金招聘Python工程师标准>>>

          Wi-Fi的操作接口封装类网上很多，系统源码也可以找出来，这里的主题不在这里，主要是wifi的实际操作应用！可以参考

http://smallwoniu.blog.51cto.com/3911954/1334951这位博主的。

          先上2张效果图：（整体还不完善，从项目中裁剪下来的！）

2、对用ListView 的item 适配器

package com.setting.wifi;
import java.util.List;
import com.setting.wifi.R;
import android.content.Context;
import android.net.wifi.ScanResult;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
public class WifiMessItemAdapter extends BaseAdapter{
 private Context context;
 private List<ScanResult> wifiListResult;
 private ScanResult mScanResult;
 
 //构造方法
 public WifiMessItemAdapter(Context c,List<ScanResult> wifiListResult){
  this.context = c;
  this.wifiListResult = wifiListResult;
 }
 
 @Override
 public int getCount() {
  // TODO Auto-generated method stub
  if(wifiListResult==null) return 0;
  return wifiListResult.size();
 }
 @Override
 public Object getItem(int position) {
  // TODO Auto-generated method stub
  return null;
 }
 @Override
 public long getItemId(int position) {
  // TODO Auto-generated method stub
  return 0;
 }
 @Override
 public View getView(int position, View convertView, ViewGroup parent) {
     
  convertView = LayoutInflater.from(context).inflate(R.layout.wifi_set_grid_item, null);
  TextView wifiIndex = (TextView)convertView.findViewById(R.id.wifi_index);
  TextView app_tilte = (TextView)convertView.findViewById(R.id.app_title);       //wifi ssid
  TextView app_icon  =  (TextView)convertView.findViewById(R.id.wifi_code_type); //加密方式
  mScanResult=wifiListResult.get(position);
  
  wifiIndex.setText((position+1)+". ");
  app_tilte.setText(mScanResult.SSID);
  app_icon.setText(mScanResult.capabilities);
 
  return convertView;
 }
 
}

  布局文件不上传了， 还是上传工程吧，啥也不说了!
