android:entries in recyclerview

Question

I have used listview with entries attribute like below :

<ListView     android:layout_width="match_parent"     android:layout_height="match_parent"     android:entries="@array/fi"/> 

Now i am converting it to RecyclerView

<android.support.v7.widget.RecyclerView     android:id="@+id/rv"     android:layout_width="match_parent"     android:layout_height="match_parent" /> 

I want to know whether we have android:entries attribute in RecyclerView? Or any other attribute instead of entries?

Answer 1

As correctly explained in the other answers there isn't an attribute to fill the RecyclerView from xml. However using the Android Databinding you can create a similar attribute quite easily:

<?xml version="1.0" encoding="utf-8"?> <layout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto">     <android.support.v7.widget.RecyclerView         android:layout_width="match_parent"         android:layout_height="match_parent"         app:entries="@{@stringArray/fi}"         app:layoutManager="android.support.v7.widget.LinearLayoutManager"/> </layout> 

Here the binding adapter definition:

import android.databinding.BindingAdapter;  public class RecyclerViewBindings {      @BindingAdapter("entries")     public static void entries(RecyclerView recyclerView, String[] array) {         recyclerView.setAdapter(new SimpleArrayAdapter(array));     }      static class SimpleArrayAdapter extends RecyclerView.Adapter<SimpleHolder> {          private final String[] mArray;          public SimpleArrayAdapter(String[] array) {             mArray = array;         }          @Override         public SimpleHolder onCreateViewHolder(ViewGroup parent, int viewType) {             final LayoutInflater inflater = LayoutInflater.from(parent.getContext());             final View view = inflater.inflate(android.R.layout.simple_list_item_1, parent, false);             return new SimpleHolder(view);         }          @Override         public void onBindViewHolder(SimpleHolder holder, int position) {             holder.mTextView.setText(mArray[position]);         }          @Override         public int getItemCount() {             return mArray.length;         }     }      static class SimpleHolder extends RecyclerView.ViewHolder {          private final TextView mTextView;          public SimpleHolder(View itemView) {             super(itemView);             mTextView = (TextView) itemView.findViewById(android.R.id.text1);         }     } } 

Then you have to use the DataBindingUtil methods for inflate the layout.

Inflate inside an Activity:

@Override protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     DataBindingUtil.setContentView(this, R.layout.content_main); } 

Inflate inside a Fragment:

@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {     ContentMainBinding bindings = DataBindingUtil.inflate(inflater, R.layout.content_main, container, false);     return bindings.getRoot(); }
