我正在製作一個SMS應用程序，用戶在該聯繫人和消息中鍵入內容，然後單擊按鈕butenc。該按鈕必須將可變電話號碼和消息發送到另一個Java類，方法接收數據並對其進行處理。 Ecc java文件是一個獨立的java類，它鏈接到各種其他的java類，以便對消息進行操作。我有時得到一個stackoverflow錯誤，當我在代碼中操作一些東西時，應用程序運行，當我單擊enc按鈕什麼都沒有發生，但是當我單擊發送按鈕時發送消息。我相信我在將變量傳遞給Ecc類時遇到了問題。我在操作系統上遇到了各種各樣的問題，但他們都沒有解決這個問題。我所做的改變給了我上面提到的任何一個問題。我如何克服這個問題？無法從活動類中調用java類的方法

當我點擊發送按鈕被髮送的消息，但是當我點擊ECC ecc類負載啓動...
