之前寫過一篇Mvp的入門Demo，然而目前就想學習使用Kotlin+Mvp+Okhttp，寫一篇登錄加下載圖片的demo，寫的有誤的地方，希望多多指點！

效果圖：

其實代碼就和之前的"Mvp的入門Demo"都差不多，就只是加了一個BaseActivity

abstract class BaseActivity<T : BasePerseter> : Activity(),IBaseView{

    var mPresenter : T? = null
    abstract fun createView():Int
    abstract fun createPresenter():T
    abstract fun viewCreated()

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(createView())

        mPresenter = createPresenter()
        if(mPresenter != null){
            mPresenter!!.attchView(this)
        }

        viewCreated()
    }

    override fun onDestroy() {
        super.onDestroy()
        if(mPresenter != null) {
            mPresenter!!.detach()
        }
    }

}

最后附上源碼
