'java.lang.ClassCastException：com.blabber.app.login.LoginActivity不能轉換爲com.blabber.app.login.Lo ginContract $ View' –
好像你的Activity沒有實現LoginContract，因爲它應該是 –
loginPresenterModule（new LoginPresenterModule（（LoginContract.View）this））。build（）。inject（this）; 在這裏，您正在將一個活動轉換爲導致該異常的LoginContract.View。 – CodeCameo
