Robotium学习（四）- 一些关于wifi的方法

//获得WifiManager

private WifiManager getWifiManager(Instrumentation inst) { return (WifiManager) inst.getTargetContext().getSystemService( Context.WIFI_SERVICE); } // 断开WiFi连接   public boolean disconnectWifi(Instrumentation inst) { getWifiManager(inst).disconnect(); int i = 5; while (isWifiConnected(inst) == true && i > 0) { getWifiManager(inst).disconnect(); solo.sleep(2000); isWifiConnected(inst); i--; } if (i == 0 && isWifiConnected(inst)) { Log.v(TAG, "已经尝试5次，依然没有关闭WiFi"); return isWifiConnected(inst); } else { Log.v(TAG, "成功关闭WiFi"); return isWifiConnected(inst); } } //重新连接WiFi   public boolean reconnectWifi(Instrumentation inst) { getWifiManager(inst).reconnect(); int i = 5; while (isWifiConnected(inst) == false && i > 0) { getWifiManager(inst).reconnect(); solo.sleep(2000); isWifiConnected(inst); i--; } if (i == 0 && isWifiConnected(inst)) { Log.v(TAG, "已经尝试5次，依然没有连接WiFi"); return isWifiConnected(inst); } else { Log.v(TAG, "成功连接WiFi"); return isWifiConnected(inst); } } //判断WiFi连接状态 ：true表示连接；false表示未连接   public static boolean isWifiConnected(Instrumentation inst) { ConnectivityManager cm = (ConnectivityManager) inst.getContext() .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo wifiNetworkInfo = cm .getNetworkInfo(ConnectivityManager.TYPE_WIFI); return wifiNetworkInfo.isConnected(); }
