如何在moxy演示程序android中获取上下文

正确的解决方案不是在演示者中使用活动上下文。因为,在活动重新创建的情况下,此上下文将泄漏(因为演示者将仍然活着)。您可以使用应用程序上下文。可以通过演示者的构造函数传递它。

通过添加 Activity 上下文作为参数 onViewCreated() . 这样地:

//presenter super class
public void onViewCreated (Activity activity) {
    //init component here
    //this.component = ...
    injectPresenter ();
}

protected PresenterComponent getComponent () {
    return this.component;
}

protected abstract void injectPresenter ();



//presenter child class
@Override
public void onViewCreated (Activity activity) {
    super.onViewCreated(this);
}

@Override
protected void injectPresenter () {
    //you can name "inject" different ways
    //in your presenter component interface
    getComponent().inject(this);
}



//activity class
@Override
protected void onCreate () {
    //P.S.(for beginners) variable presenter is the object of class
    //which extends Presenter super class
    presenter.onViewCreated(this);
}
