判断Android的WIFI与GPS状态，并引导用户前去开启GPS与WIFI设置

需要配置权限

  <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

判断Android的WIFI与GPS状态

    private void checkWifiAndGpsStatus() { boolean result = true; /* 取得WifiManager与LocationManager */ WifiManager wManager = (WifiManager) getSystemService(Context.WIFI_SERVICE); LocationManager lManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); /* 确认WiFi服务是关闭且不在开启运行中 */        if (!wManager.isWifiEnabled() && wManager.getWifiState() != WifiManager.WIFI_STATE_ENABLING) { tv01.setText("Wifi状态：未启动"); result = false; } else { tv01.setText("Wifi状态：已启动"); } /* 确认GPS是否开启 */        if (!lManager.isProviderEnabled(LocationManager.GPS_PROVIDER) || !lManager .isProviderEnabled(LocationManager.NETWORK_PROVIDER)) { tv02.setText("GPS状态：未启动"); result = false; } else { tv02.setText("GPS状态：已启动"); } if (result) { mButton03.setEnabled(true); } else { mButton03.setEnabled(false); } }
