问题 I have been using data binding for the past few weeks and now am trying to use a two way data binding for a custom view with a 'value' attribute. My problem is that I get the following error when building. Cannot find a getter for <com.twisthenry8gmail.dragline.DraglineView app:value> that accepts parameter type 'long' Now it was my understanding that the binding library will automatically use my public setters and getters however the most confusing part is adding a redundant inverse binding

问题 My code shuffles colors and indexes for a list of ColorBox objects indefinitely. This is my view: <TextView style="@style/App.WidgetStyle.ColorBox" android:text="@{item.id}" android:theme="@{item.theme}" tools:text="A" tools:theme="@style/App.ColorBox" /> My styles: <style name="App.WidgetStyle.ColorBox" parent="App"> <item name="android:layout_width">@dimen/square_size</item> <item name="android:layout_height">@dimen/square_size</item> <item name="android:background">@drawable/shape_for

问题 I'm starting to play with Android binding. The standard (1-way) binding is to the point of being good enough for the people I hang out with. However, I find that I can't use Lombok accessors without a Could not find accessor error. Have you found a way around this, shy of manually writing getters and setters like some kind of Lombok-ignorant cavebeast? @Bindable @Getter @Setter private String stringField; //Must uncomment hand-coded accessors to compile! //public String getStringField() {

问题 I have a ViewModel with: val imageUrl = ObservableField<String>() My layout XML has: <ImageView ... app:url="@{viewModel.imageUrl}" .../> I have a BindingAdapters file with a top level function: @BindingAdapter("url") fun loadImage(view: ImageView, url: String?) { ... } I'm getting the following error: data binding error msg:Cannot find the setter for attribute 'app:url' with parameter type android.databinding.ObservableField<java.lang.String> on android.widget.ImageView.

The BindingAdapter looks as follows: @BindingAdapter("binding:singleParameterString", "binding:firstStringParameter") fun setFormattedString(btn: Button, singleParameterString: String,

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
