##Android Data Binding 代码实战
本代码用来练习Android Data Binding技术
###目前实现
豆瓣电影搜索
利用Data Binding在RecycleView展示电影列表
###Model
public class Movie extends BaseObservable {
private String id;
private String title;
private String original_title;
private String year;
private Images images;
private Rating rating;
@Bindable
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
notifyPropertyChanged(BR.title);
}
@Bindable
public String getDescription() {
return this.original_title + "\n" + this.getYear();
}
public void setOriginal_title(String original_title) {
this.original_title = original_title;
notifyPropertyChanged(BR.description);
}
public void setYear(String year) {
this.year = year;
notifyPropertyChanged(BR.description);
}
...
}###Layout
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<data>
<variable
name="movie"
type="com.aswifter.databinding.model.Movie" />
</data>
...
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@{movie.title}"

android:rating="@{movie.rating.average}"
android:stepSize="0.5" />
</LinearLayout>
...
</layout>###Binding
Movie movie = mMovies.get(position);
Glide.with(MovieActitiviy.this)
.load(movie.getImages().getMedium())
.fitCenter()
.into(holder.binding.ivMovie);
holder.binding.setVariable(com.aswifter.databinding.BR.movie, movie);
holder.binding.executePendingBindings();
