项目扩展为mvvm后，titleBar 无效了

[D-zy]

博主，请问下，使用 数据绑定时， mDatabind = DataBindingUtil.setContentView(this, contentLayout) 加载布局之后，titleBar 无效了

[Aries Hoo²⁰²¹]

具体是如何无效？是获取不到titleBar还是？

[D-zy]

在子类activity里 override fun setTitleBar(titleBar: TitleBarView) {
titleBar.setTitleMainText(“xx”) 这里不起作用了
}

给我看看你那个子类的完整代码呢
我感觉像是那个layoutId不一致造成的。。。BasisActivity获取的layout和你dataBinding的不是同一个

[D-zy]

abstract class FastTitleActivity<VM : ViewModel, DB : ViewDataBinding> : BasisActivity(), IFastTitleView {
protected lateinit var mDatabind: DB
protected var mFastTitleDelegate: FastTitleDelegate? = null
protected var mTitleBar: TitleBarView? = null

override fun beforeInitView(savedInstanceState: Bundle?) {
    super.beforeInitView(savedInstanceState)
    mFastTitleDelegate = FastTitleDelegate(mContentView, this, this.javaClass)
    mTitleBar = mFastTitleDelegate!!.mTitleBar
}

override fun onCreate(savedInstanceState: Bundle?) {
    userDataBinding(true)
    super.onCreate(savedInstanceState)
}

/**
 * 创建liveData观察者
 */
override fun createObserver() {}

/**
 * 创建DataBinding
 */
override fun initDataBind() {
    mDatabind = DataBindingUtil.setContentView(this, contentLayout)
    mDatabind.lifecycleOwner = this
}

}

以下是base:----------------------------------------------------

abstract class BasisActivity : RxAppCompatActivity(), IBasisView {

/**
 * 是否需要使用DataBinding 供子类BaseVmDbActivity修改，用户请慎动
 */
private var isUserDb = false

lateinit var mViewModel: VM

@JvmField
protected var mContext = Activity()

@JvmField
protected var mContentView: View? = null

@JvmField
protected var mSavedInstanceState: Bundle? = null
protected var mIsViewLoaded = false
protected var mIsFirstShow = true
protected var mIsFirstBack = true
protected var mDelayBack: Long = 2000

@JvmField
protected val TAG = javaClass.simpleName
override fun attachBaseContext(base: Context) {
    super.attachBaseContext(LocaleManagerUtil.setLocal(base))
}

override fun onCreate(savedInstanceState: Bundle?) {
    if (isEventBusEnable) {
        EventBus.getDefault().register(this)
    }
    super.onCreate(savedInstanceState)
    mSavedInstanceState = savedInstanceState
    mContext = this
    beforeSetContentView()
   ### ### ###      ### ### ###      ### ### ### 主要改动在这里：
 mContentView = View.inflate(mContext, contentLayout, null)
    if (!isUserDb) {
        setContentView(mContentView)
    } else {
        initDataBind()
    }

 ### ### ###      ### ### ###      ### ### ### 
    mIsViewLoaded = true
    beforeInitView(savedInstanceState)
    mViewModel = createViewModel()
    initView(savedInstanceState)
    createObserver()
    initListener()
}


/**
 * 创建viewModel
 */
private fun createViewModel(): VM {
    return ViewModelProvider(this).get(getVmClazz(this))
}

open fun initDataBind() {}

}

这都不是我的基类了，所以我也不知道为啥不会执行，要不你给我个最简单的demo

[D-zy]

只是在你基类上稍微扩展了下，

已解决
