Displaying Data In A Recyclerview

I have this working perfectly with a ListView, but decided to update my code to use RecyclerView. I see there is no default implementation, and the responses to similar questions a

Solution 1:

Your can try

1. In your activity

   ArrayList<Author> authors = dbHandler. getAllAuthors();
   recyclerView.setHasFixedSize(true);
   
   // ListView
   recyclerView.setLayoutManager(newLinearLayoutManager(youractivity.this));
   
   
   // create an Object for AdapterCardViewDataAdapter1mAdapter=newCardViewDataAdapter1(authors);
   
   // set the adapter object to the Recyclerview
   recyclerView.setAdapter(mAdapter);
   

2. Your adapter is look like

   classCardViewDataAdapter1extendsRecyclerView.Adapter<CardViewDataAdapter1.ViewHolder> {
      private ArrayList<Author> dataSet;
   
   
   publicCardViewDataAdapter1(ArrayList<Author> os_versions) {
   
       dataSet = os_versions;
   }
   
   
   @Overridepublic CardViewDataAdapter1.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
     // create a new viewViewitemLayoutView= LayoutInflater.from(viewGroup.getContext()).inflate(
               R.layout.recycler_item, null);
   
       itemLayoutView.setLayoutParams(newRecyclerView.LayoutParams(RecyclerView.LayoutParams.MATCH_PARENT, RecyclerView.LayoutParams.WRAP_CONTENT));
   
       // create ViewHolder
   
       CardViewDataAdapter1.ViewHolderviewHolder=newCardViewDataAdapter1.ViewHolder(itemLayoutView);
   
       return viewHolder;
   }
   
   @OverridepublicvoidonBindViewHolder(CardViewDataAdapter1.ViewHolder viewHolder, int i) {
   
       Authorfp= dataSet.get(i);
   
       viewHolder.tv_name.setText(fp.getName());
   
   
   
   
       viewHolder.menu = fp;
   }
   
   @OverridepublicintgetItemCount() {
   
       return dataSet.size();
   }
   
   publicvoidupdateList(List<Author> temp) {
       dataSet = (ArrayList<Author>) temp;
       notifyDataSetChanged();
   }
   
   // inner class to hold a reference to each item of RecyclerViewpublicclassViewHolderextendsRecyclerView.ViewHolder {
   
       public TextView tv_name;
   
   
       public Author menu;
       publicViewHolder(View itemLayoutView) {
           super(itemLayoutView);
   
           tv_name = (TextView) itemLayoutView  .findViewById(R.id.tv_name);
   
   
          }
   
      }
    }
   

3. Your recycler_item.xml

   <?xml version="1.0" encoding="utf-8"?><android.support.v7.widget.CardViewxmlns:android="http://schemas.android.com/apk/res/android"xmlns:card_view="http://schemas.android.com/apk/res-auto"android:layout_width="match_parent"android:layout_height="match_parent"card_view:cardCornerRadius="5dp"card_view:cardBackgroundColor="#FFFFFF"card_view:cardUseCompatPadding="true"
      ><LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="vertical"><TextViewandroid:id="@+id/tv_name"android:layout_width="match_parent"android:layout_height="wrap_content"android:text="Enamul"/></LinearLayout></android.support.v7.widget.CardView>
