I have create a binding adapter to display picture with picasso, but it doesn't work. I have the following error :
Found data binding errors. ****/ data binding error ****msg:Cannot find the setter for attribute 'app:loadPicture' with parameter type java.lang.String on android.widget.ImageView. file:/home/groupevsc.com/mathieu_labar/Documents/Projects/android-jetpack/app/src/main/res/layout/activity_detail_movie.xml loc:27:31 - 27:52 ****\\ data binding error ****
Here is my binding adapter :
object CommonBindingUtil {
@JvmStatic
@BindingAdapter("loadPicture")
fun loadPicture(view: ImageView, text: String) {
Picasso.with(view.context)
.load(text)
.error(R.drawable.ic_movie_24)
.fit()
.placeholder(R.drawable.ic_movie_24)
.into(view)
}
}
And my XML has attribute "app:loadPicture" :
<ImageView
android:id="@+id/picture"
android:layout_width="@dimen/material_image_simple_width"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:src="@drawable/ic_movie_24"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:loadPicture="@{viewModel.movie.Poster}"/>
Here is my GitHub repository: https://github.com/mlabar/android-jetpack/tree/tech_ajout_databinding
Would anyone have an idea to solve my problem?
Thank you!
谢谢@Blackbelt 解决了我的问题,我在所有build.gradle
模块中添加了“kotlin-kapt”:
apply plugin: 'kotlin-kapt'
Here is my code
@JvmStatic
@BindingAdapter({"bind:loadPicture"})
fun loadPicture(view: ImageView, loadPicture: String) {
Picasso.with(view.context)
.load(loadPicture)
.error(R.drawable.ic_movie_24)
.fit()
.placeholder(R.drawable.ic_movie_24)
.into(view)
}
for more details see my project on GitHub
Change your MovieViewModel class like this:
class MovieViewModel(private val movie: Movie) : Observer, BaseObservable() {
init {
Movie.addObserver(this)
}
val Poster: String
@Bindable get() {
return Poster.name
}
}
And Movie class like this:
class Movie: Observable() {
var Title: String = ""
set(value) {
field = value
setChangedAndNotify("Title")
}
var Year: String = ""
set(value) {
field = value
setChangedAndNotify("Year")
}
var imdbID: String = ""
set(value) {
field = value
setChangedAndNotify("imdbID")
}
var Type: String = ""
set(value) {
field = value
setChangedAndNotify("Type")
}
var Poster: String = ""
set(value) {
field = value
setChangedAndNotify("Poster")
}
var Plot: String = ""
set(value) {
field = value
setChangedAndNotify("Plot")
}
private fun setChangedAndNotify(field: Any) {
setChanged()
notifyObservers(field)
}
}
Make your class context according to your need, run it hope it'll solve your problem.
You are not passing the right parameters for binding adapter function.
object CommonBindingUtil {
@JvmStatic
@BindingAdapter("loadPicture")
fun loadPicture(view: ImageView, text: String) {
Picasso.with(view.context)
.load(text)
.error(R.drawable.ic_movie_24)
.fit()
.placeholder(R.drawable.ic_movie_24)
.into(view)
}
}
Here loadPicture
function expects parameters imageView
and a String, but here, in your xml your are passing the Object of photo
app:loadPicture="@{viewModel.movie.Poster}
You should instead write something like this app:loadPicture="@{viewModel.movie.Poster.url}
