Efficient Adapter for Android
Create a new adapter for a RecyclerView or ViewPager is now much easier.
Overview
Create a list of elements into a RecyclerView or ViewPager is not that easy for a beginner, and repetitive for others. The goal of this library is to simplify that for you.
How does it work?
Create a class ViewHolder (BookViewHolder
for example). The method updateView
will be call with the object, when an update of your view is require:
public class BookViewHolder extends EfficientViewHolder<Book> {
public BookViewHolder(View itemView) { super(itemView); }
@Override
protected void updateView(Context context, Book object) {
TextView textView = findViewByIdEfficient(R.id.title_textview);
textView.setText(object.getTitle());
// or just
setText(R.id.title_textview, object.getTitle());
}
}
Give this ViewHolder class to the constructor of the adapter (SimpleAdapter) of your RecyclerView, with the resource id of your item view and the list of objects:
EfficientRecyclerAdapter<Plane> adapter = new EfficientRecyclerAdapter<Plane>(R.layout.item_book, BookViewHolder.class, listOfBooks);
recyclerView.setAdapter(adapter);
And that's it!
It's also working with a ViewPager:
EfficientPagerAdapter<Plane> adapter = new EfficientPagerAdapter<Plane>(R.layout.item_book, BookViewHolder.class, listOfBooks);
viewPager.setAdapter(adapter);
Other features
Heterogenous list
For a list of different kind of objects, layout, viewholder…
EfficientRecyclerAdapter adapter = new EfficientRecyclerAdapter(generateListObjects()) {
@Override
public int getItemViewType(int position) {
if (get(position) instanceof Plane) {
return VIEW_TYPE_PLANE;
} else {
return VIEW_TYPE_BOOK;
}
}
@Override
public Class<? extends EfficientViewHolder> getViewHolderClass(int viewType) {
switch (viewType) {
case VIEW_TYPE_BOOK:
return BookViewHolder.class;
case VIEW_TYPE_PLANE:
return PlaneViewHolder.class;
default:
return null;
}
}
@Override
public int getLayoutResId(int viewType) {
switch (viewType) {
case VIEW_TYPE_BOOK:
return R.layout.item_book;
case VIEW_TYPE_PLANE:
return R.layout.item_plane;
default:
return 0;
}
}
};
Efficient findViewById()
Because findViewById(int)
is CPU-consuming (this is why we use the ViewHolder pattern), this library use a findViewByIdEfficient(int id)
into the ViewHolder class.
You can use it like a findViewById(int id)
but the view return will be cached to be returned into the next call.
Your view id should be unique into your view hierarchy, but sometimes is not that easy (with an include for example). It's now easier to find a subview by specify the parent of this subview with findViewByIdEfficient(int parentId, int id)
to say "the view with this id into the parent with this id".
Let the element be clickable
Your ViewHolder class can override the method isClickable()
to tell is this element is clickable or not.
By default, the view is clickable if you have a listener on your adapter.
Proguard
This library includes the proguard configuration file. If you want to add it manually:
-keepclassmembers public class * extends com.skocken.efficientadapter.lib.viewholder.EfficientViewHolder {
public <init>(...);
}
Gradle
dependencies {
compile 'com.skocken:efficientadapter:2.4.0'
}
Android Support library
If you are still using the deprecated Android Support Library (instead of AndroidX), please use the dependency 2.3.X instead.
