Androidモバイルデータインターネットのスイッチの実現

解決策としてConnectivityManagerクラスが使用されていますが、SDKのConnectivityManagerクラスではsetMobileDataEnable()やgetMobileDataEnable()などの方法は提供されていません.ConnectivityManagerクラスのソースコードも見ましたが、これらの方法があります.長い間やっていましたが、結局思い切って、自分でConnectivityManagerクラスを書きました.その中の方法はソースConnectivityManagerクラスの方法と同じですが、すべて空で実現し、ConnectivityManagerにコンパイルしました.classファイルを置き換えandroid.JArパッケージのandroid.net.ConnectivityManager.classファイル.その後、プロジェクトでは、ConnectivityManagerのsetMobileDataEnable()メソッドを使用してデータのインターネットをオン/オフし、getMobileDataEnable()メソッドを使用して現在の接続状態を取得します.もちろんandroidが必要です.permission.CHANGE_NETWORK_STATEとandroidpermission.ACCESS_NETWORK_STATE権限.
元の解決方案はCSDN問答から来て、更に多くの解決方案は見ますhttp://ask.csdn.net/questions/152
