android 给我一段代码，点击一个按钮，手机就连上指定的wifi

Answer 1

public class HotspotActivity extends Activity {
private WifiManager wifiManager;
private Button open;
private boolean flag=false;

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//获取wifi管理服务
wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
open=(Button)findViewById(R.id.open_hotspot);
//通过按钮事件设置热点
open.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//如果是打开状态就关闭，如果是关闭就打开
flag=!flag;
setWifiApEnabled(flag);
}
});
}

// wifi热点开关
public boolean setWifiApEnabled(boolean enabled) {
if (enabled) { // disable WiFi in any case
//wifi和热点不能同时打开，所以打开热点的时候需要关闭wifi
wifiManager.setWifiEnabled(false);
}
try {
//热点的配置类
WifiConfiguration apConfig = new WifiConfiguration();
//配置热点的名称(可以在名字后面加点随机数什么的)
apConfig.SSID = "YRCCONNECTION";
//配置热点的密码
apConfig.preSharedKey="12122112";
//通过反射调用设置热点
Method method = wifiManager.getClass().getMethod(
"setWifiApEnabled", WifiConfiguration.class, Boolean.TYPE);
//返回热点打开状态
return (Boolean) method.invoke(wifiManager, apConfig, enabled);
} catch (Exception e) {
return false;
}
}
}
