作者有没有开发AS plugin的打算？

例如 https://github.com/y1xian/KotlinMvp
使用起来很方便

关于ContainerActivity的返回

默认打开ContainerActivity是没有返回功能的，要怎么定制actionbar呢

使用的方法有误，应该是执行： onScrollStateChangedCommand.execute(Integer.valueOf(scrollState))；才对？

MVVMHabit/mvvmhabit/src/main/java/me/goldze/mvvmhabit/binding/viewadapter/recyclerview/ViewAdapter.java

Line 44 in 89ada4a

onScrollChangeCommand.equals(newState);

include怎么用啊

用了这个框架,include复用布局不知怎么弄了

大神您好，请问网络请求那块，统一API错误怎么传到activity或fragment去处理啊，后期能把这块添加个示例吗

ContainerActivity返回到指定的ContainerActivity

当使用startContainerActivity多次来跳转ContainerActivity的时候，这时候要跳转到指定的某个fragment，怎么操作，望大神指教。谢谢

Paging library 库来实现分页

您好，分页能可不可以用 Paging library 库来实现啊？我试了半天不知道该如何实现

onBackPressed

大神你好！按照你得这种封装思路，那么在Activity和viewmodel中都不再持有view的引用，全部通过观察者的模式把逻辑回调到viewmodel中进行处理，但我现在有一个场景，就是一个dialog，在点击onBackPressed的时候要处理关闭dialog。这个时候这个事件处理是在Activity里面处理还是传递到viewmodel中合适呢？ 而且这个时候dialog的对象怎么拿到呢。findviewbyid么。望指教

Toast怎样去掉自带的 app_name

找了半天没看到，在哪里去掉前面自带的app_name

BR.viewModel

@Override
public int initVariableId() {
    return BR.viewModel
}

这个是什么 viewmodel 找不到啊

求学习资料

请问下，有关于
me.tatarka.bindingcollectionadapter2:bindingcollectionadapter:2.2.0
me.tatarka.bindingcollectionadapter2:bindingcollectionadapter-recyclerview:2.2.0
这个版本的学习资料或者链接吗？
想了解下和旧版本有什么区别，我用activity 显示列表 直接编译不过去

ViewModel的onDestroy没有回调

测试发现ViewModel的onDestroy没有回调，比如关闭页面，DetailViewModel的onDestroy没有回调，其他生命周期方法回调了。

有个问题

如何调用startActivityForResult方法，比如想调用相机获得照片

能增加对接MultiType 的recyeclerview例子吗

能增加对接MultiType 的recyeclerview例子吗，包括点击不同item的点击处理，最好列表外面能加个smartrefreshlayout

请教 ApiDisposableObserver 的使用方法

需要在接口请求后统一处理返回结果，如统一更新返回结果中的token，无意中发现这个类，请教下使用方法

这个框架的viewmodel好像和官方的原则不太一样

官方https://developer.android.google.cn/topic/libraries/architecture/viewmodel

Caution: A ViewModel must never reference a view, Lifecycle, or any class that may hold a reference to the activity context.

而在这里viewmodel持有了activity context，不会有问题吗？

xml看不见效果图

这个效果图有时看的见,代码也没动,后来就看不见了,用的就是demo的界面一模一样啊

开始挺好用的，现在欲仙欲死的状态

android studio对databinding的支持不够，硬伤

recycleview复杂一些那真的是头痛啊

viewmodel和View逻辑分离，数据驱动界面更新，看起来很美好，可是用下去你就会发现真正项目中是不能这样的

我现在使用的这个框架，另外使用mvp模式，相当于mvp+mvvm，但是现在欲仙欲死，有没有同道中人，打算老老实实的用mvp写了，databinding只用于界面绑定，可能mvvm现在还不够成熟吧

网络请求带空的HashMap,Printer会报错

项目跑起来的错误

直接跑，没任何改动...用的gradle4.1

BaseViewModel中的LiveData每次获取都会创建一个新的返回

例如：

 public SingleLiveEvent<String> getShowDialogEvent() {
            return showDialogEvent = createLiveData(showDialogEvent);
}

扩展性

如果想对BaseActivity进行扩展，例如添加一些通用的title，状态页，该怎么做？initContentView只能返回一个View，initViewDataBinding也无法复写

第一页跳转第二页怎么携带数据？

加个Recyclerview的例子就完美了

Bug问题，统一在此反馈

如果您在使用中发现存在Bug，请在此提出，感谢您的反馈！

大佬，RetrofitClient这个封装类怎么使用，有例子吗

demo里的model.demoGet() 这个 还有addSubscribe()这个都是什么意思 他们3个都一样的意思吗

Demo可以在补充上功能吗

已经start，
大神，首先要感谢你，你写的项目给我带来很大的帮助，你是我在github中找到的项目中写的最好的一个，如果Demo能在详细点就好了，对我们这些初学者会带来很大的帮助。

1. 可以增加一个购物车的例子吗？比方产品详情页面中添加或则取消产品时刷行购物车，还有商品详情可以读取和刷新购物数量
2. Recyclerview 例子不是很完整，可以增加分页处理的逻辑吗

R

扩展问题

请教博主：
1.如果RecyclerView如果绑定的item是多种样式的怎么使用ItemBinding 模式在xml进行itemBinding呢。这里默认的itemBinding都是传一个R.layout.xx的布局进去，那多个布局样式的呢？
2.怎么支持扩展呢，比如MD的BottomNavigationView控件怎么封装在xml直接使用binding的方式绑定数据呢，而且有可能是服务器返回的动态tab的绑定信息

跪求博主回复，现在对databinding还是小白。但是很希望把这个框架用起来

安卓新手表示五星好评 , 架构设计感觉非常清晰合理.使用起来应该很方便

持续关注中 .

不同状态的布局切换，该怎么处理

例如使用：https://github.com/jakubkinst/Android-StatefulLayout
statefulLayout.setStateView(STATE_NO_PERSMISSION, LayoutInflater.from(this).inflate(R.layout.state_no_permission, null));
statefulLayout.setStateView(STATE_PROGRESS, LayoutInflater.from(this).inflate(R.layout.state_progress, null));

如果我使用mvvm来写，我应该怎么写好

大神请教你一个问题

SubmitTransitionButton一个view控件，有onSuccess()和onFailure()这两个方法(xml是没有属性可以调用这两个方法。只能在代码里面调用).
请问如果我用mvvmHabit 我要怎么控制，可以写个例子吗，还有怎么获取获取页面的view 例如 binding.mainTv1.setText();
