Здесь я дал вам четкое объяснение,
Создание одного общего Interface с именем CustomItemClickListenere
public interface CustomItemClickListenere {
public void onItemClick(View v, int position); }
Измените класс адаптера, как показано ниже,
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {
private ArrayList<AddSingleItemList> data;
private Context mContext;
private CustomItemClickListenere listener;
public RecyclerViewAdapter(Context mContext, ArrayList<AddSingleItemList> data, CustomItemClickListenere listener) {
this.data = data;
this.mContext = mContext;
this.listener = listener;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View mView = LayoutInflater.from(parent.getContext()).inflate(R.layout.items_list_single_item, parent, false);
final ViewHolder mViewHolder = new ViewHolder(mView);
mView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
listener.onItemClick(v, mViewHolder.getPosition());
}
});
return mViewHolder;
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.itemTitle.setText(Html.fromHtml(data.get(position).getTitle()));
}
@Override
public int getItemCount() {
return data.size();
}
public static class ViewHolder extends RecyclerView.ViewHolder {
public TextView itemTitle;
public CardView cardView;
ViewHolder(View v) {
super(v);
itemTitle = (TextView) v.findViewById(R.id.person_name);
cardView = (CardView) v.findViewById(R.id.cv);
}
}
}
адаптер xml item_list_single_item :
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/cv"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="5dp">
<TextView
android:id="@+id/person_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:textSize="12sp" />
</RelativeLayout>
</android.support.v7.widget.CardView>
Здесь я создал класс Pojo для установки статических элементов на Recyclerview, названный AddSingleItemList :
public class AddSingleItemList {
private String title;
long id;
/**
*
* @param id
* @param title
*/
public AddSingleItemList(long id, String title) {
this.id = id;
this.title = title;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
}
Обновление RecyclerViewActivity как показано ниже:
public class RecyclerViewActivity extends AppCompatActivity {
RecyclerView itemsList;
RecyclerViewAdapter adapter;
ArrayList<AddSingleItemList> data = new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
itemsList = (RecyclerView) findViewById(R.id.items_list);
LinearLayoutManager llm = new LinearLayoutManager(this);
itemsList.setLayoutManager(llm);
itemsList.setHasFixedSize(true);
//Add you items into the Recyclerview list
data.add(new AddSingleItemList(1, "First Item"));
data.add(new AddSingleItemList(2, "Second Item"));
adapter = new RecyclerViewAdapter(this, data, new CustomItemClickListenere() {
@Override
public void onItemClick(View v, int position) {
Log.d("RecyclerViewActivity", "clicked position:" + position);
Toast.makeText(RecyclerViewActivity.this, "Good News : I'm working", Toast.LENGTH_SHORT).show();
// do what ever you want to do with it
}
});
itemsList.setAdapter(adapter);
}
}
В итоге вы получите результат, как вы подняли в своем вопросе,
