判斷Android的WIFI與GPS狀態，並引導用戶前去開啟GPS與WIFI設置

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啟運行中 */
        if (!wManager.isWifiEnabled() && wManager.getWifiState() != WifiManager.WIFI_STATE_ENABLING) { tv01.setText("Wifi狀態：未啟動"); result = false; } else { tv01.setText("Wifi狀態：已啟動"); } /* 確認GPS是否開啟 */
        if (!lManager.isProviderEnabled(LocationManager.GPS_PROVIDER) || !lManager .isProviderEnabled(LocationManager.NETWORK_PROVIDER)) { tv02.setText("GPS狀態：未啟動"); result = false; } else { tv02.setText("GPS狀態：已啟動"); } 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);
   startActivityForResult(intent, 0);
