私の問題は、2 つのクラスがあることです。1 つ目は Runnable を実装する実装クラスで、2 つ目はフレームビューを拡張する interfaceView です。
しかし、実装クラスでinterfaceViewのオブジェクトを作成しようとすると、たとえば
interfaceview check1 ;
check1.get_sms_validation();
それは私に与えます
java.lang.IllegalArgumentException: null アプリケーション
例外
実装クラスのコードは
しかし、私がするとき
interfaceview check1 = new interfaceview () ;
check1.get_sms_validation();
インターフェイスビュークラスでコンストラクターを作成するように指示され、それを行うとエラーが発生します
実際のリストと正式なリストは長さが異なります。
