需要配置權限

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

判斷Android的WIFI與GPS狀態

 private void checkWifiAndGpsStatus() {
        boolean result = true;
        /* 取得WifiManager與LocationManager */
        WifiManager wManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
        LocationManager lManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

        /* 確認WiFi服務是關閉且不在開啓運行中 */
        if (!wManager.isWifiEnabled()
                && wManager.getWifiState() != WifiManager.WIFI_STATE_ENABLING) {
            tv01.setText("Wifi狀態：未啓動");
            result = false;
        } else {
            tv01.setText("Wifi狀態：已啓動");
        }
        /* 確認GPS是否開啓 */
        if (!lManager.isProviderEnabled(LocationManager.GPS_PROVIDER)
                || !lManager
                        .isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
            tv02.setText("GPS狀態：未啓動");
            result = false;
        } else {
            tv02.setText("GPS狀態：已啓動");
        }
        if (result) {
            mButton03.setEnabled(true);
        } else {
            mButton03.setEnabled(false);
        }
    }

跳轉至Wifi設置畫面

   Intent intent = new Intent(android.provider.Settings.ACTION_WIFI_SETTINGS);
   startActivityForResult(intent, 0);

跳轉至GPS設置界面

   Intent intent = new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
