方法ongreate()未调用

Question

app/build.gradle：

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
dependencies {
...
implementation 'com.hannesdorfmann.mosby3:mvi:3.1.0'
    implementation 'com.hannesdorfmann.mosby3:mvp:3.1.0'
    implementation 'com.hannesdorfmann.mosby3:viewstate:3.1.0'
implementation 'com.hannesdorfmann.mosby3:mvp-lce:3.1.0'
}

在这里我的活动：

import com.hannesdorfmann.mosby3.mvp.MvpActivity;
    public class OfferDetailsPdfActivity extends MvpActivity<OfferDetailsPdfMvp.View, OfferDetailsPdfPresenterImplMvp> implements OnPageChangeListener, OfferDetailsPdfMvp.View {
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
    }
    }

和我的活动中的方法 onCreate() uperveDetailSpdFactivity 是成功的调用。

但是我需要将参数传递给活动，所以在这里生产代码：

public class OfferDetailsPdfActivity extends MvpActivity<OfferDetailsPdfMvp.View, OfferDetailsPdfPresenterImplMvp> implements OnPageChangeListener, OfferDetailsPdfMvp.View {
private OfferDetailsPdfPresenterImplMvp presenter;
    private int offerId;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Bundle extras = getIntent().getExtras();
        Debug.d(TAG, "onCreate: extras = " + AndroidUtil.bundle2String(extras)
                + "nsavedInstanceState = " + AndroidUtil.bundle2String(savedInstanceState)
        );
        if (extras != null) {
            offerId = extras.getInt(Offer.ID);
        }
            setContentView(R.layout.offer_details_pdf);
        ButterKnife.bind(this);
    }
    @NonNull
    @Override
    public OfferDetailsPdfPresenterImplMvp createPresenter() {
        Debug.d(TAG, "createPresenter: offerId = " + offerId);
        presenter = new OfferDetailsPdfPresenterImplMvp(this, offerId);
        return presenter;
    }

现在，在我的活动方法中，onCreate()不是调用的，但是方法createPresenter()是成功的。有文本" createPresenter：upervid = 0"

从logcat中可以看到，方法onCreate()未调用。在logcat中没有文本" oncreate：extras ... "

为什么？

在这里logcat：

您无需upplyID即可执行父量。更改以下两行

super.onCreate(savedInstanceState);
Bundle extras = getIntent().getExtras();

：

Bundle extras = getIntent().getExtras();
if (savedInstanceState == null) { 
    super.onCreate(extras); 
}
