android-databinding

问题 (Note: this is a follow up question to Is it possible to use androidx-navigation with onClick-databinding without writing boilercode in Fragment? I want to use androidx-databinding to handle onClick calling a static method with parameters Utils.myNavigate(...) via the xml-layout-file My Code below is verifyed by the compile process but is never called when i click on the button. How to fix this? My Layoutfile: <layout ...> <data> <import type="de.k3b.androidx.navigationdemo.R" /> <import type

问题 I want to implement an androidx-navigation by using databinding instead of implementing onClick handler in code I have a List-fragment with a livedata element selectedItemId and want to open a correspondeng detail-fragment when pressing the edit button. Is something similar to this possible <layout> <data> <!-- assuming that com.example.MyGeneratedNavigation was generated from .../res/navigation/my_navigation.xml --> <variable name="myNavigation" type"com.example.MyGeneratedNavigation" />

问题 I have a spinner now and I want to load the data to the spinner with data binding feature. I tried to find the way to declare the string array in the XML(https://developer.android.com/topic/libraries/data-binding/index.html#expression_language) but no satisfied result is found. <layout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:apps="http://schemas.android.com/apk/res-auto"> <data> <import type="android.util.SparseArray"/> <variable name="statuslist" type="SparseArray

问题 I googled but still didn't find solution for me. This is my xml: <?xml version="1.0" encoding="utf-8"?> <layout xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools"> <data> <import alias="noteViewModel" type="com.app.screen.createnote.CreateNoteViewModel" /> </data> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical">

问题 I'm using data binding within my app. I have an application module and the data binding is working successfully. However, I also have a 'home-module' I'm trying to use the same techniques, but the data binding is erroring in the xml with the following: Error:(63, 34) No resource type specified (at 'onClick' with value '@{viewModel::onButtonClicked}'). I've found this bug report which suggests this was an issue but it's been fixed. I can't see any issues with the code, I think the problem is

问题 When I switch my app language between EN and AR (during runtime) the views behave correctly by moving from the LTR to the RTL but when I start stressing the app by switching languages many times the layout direction become missy and I get RTL elements when the app is supposed to show LTR elements. Sometimes the layout direction is not refreshed anymore. As workaround I have to set the layout direction programmatically for those views. binding.spinner.setLayoutDirection(LocaleUtil.isRtl(this)

问题 I have my viewmodels contained in a "ViewModels" package. When setting one of them as a data variable type in my fragment layout xml file the generated ViewDataBinding class attempts to import the package as if it were a file. For example: import com.xyz.myapp.ViewModels; Rather than: import com.xyz.myapp.ViewModels.*; It then goes on to reference the viewmodel as ViewModels.MyFragmentViewModel causing further errors. I found that a workaround for this is to put all my viewmodel files in my

问题 I have a multi module project which is structured something like this. Here is the code to play around with this error: https://github.com/ajitsing/MultiModuleAndroid Root |- App Module (Application, Data binding enabled) |- Lib Module (Library, Data binding enabled) Main module depends on the Lib module. Lib module contains all the android tests. When I run the androidTests of just lib module with testCoverageEnabled it throws some weird data binding error. All these error are for custom

问题 I am trying to use DataBinding in my existing project. As per the documentation I added below lines in app module's build.gradle and compiled the project. dataBinding { enabled = true } I got the below error: Could not resolve all dependencies for configuration ':app:devDebugCompileClasspath'. Could not find com.android.databinding:baseLibrary:3.0.0-alpha3. Searched in the following locations: file:/C:/Users/incnayak/AppData/Local/Android/sdk/extras/m2repository/com/android/databinding

问题 Is there any way to wire up custom onSomeEventListener to the attribute using binding library? Examples provided for onClick are simple and they all use 'on' prefix and single-method interface listeners, and what about 'add' prefix and more complicated scenarios? Imagine I want to use custom wire up logic on RecyclerView.addOnItemTouchListener, determining the child view was touched from SimpleOnItemTouchListener.onTouchEvent and passing it to my view model, how can I achieve this? I want to
