 LayoutInflater inflater;

 public CustomSpinnerAdapter(Context context, ArrayList<String> objects) {
  super(context, R.layout.spinner_row, objects);

  context1 = context;
  data = objects;

  inflater = (LayoutInflater) context1
    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

 }

 @Override
 public View getDropDownView(int position, View convertView, ViewGroup parent) {
  return getCustomView(position, convertView, parent);
 }

 @Override
 public View getView(int position, View convertView, ViewGroup parent) {
  return getCustomView(position, convertView, parent);
 }

 // This funtion called for each row ( Called data.size() times )
 public View getCustomView(int position, View convertView, ViewGroup parent) {

  View row = inflater.inflate(R.layout.spinner_row, parent, false);

Update:
======

Since the spinner dropdown is not like the new LollyPop Design like Spinner:

We need to add small code for the spinner control

 android:dropDownVerticalOffset="-52dp" for Kitkat and below

 android:dropDownVerticalOffset="0dp" for LollyPop



 <Spinner
        android:id="@+id/spinner_nav"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:dropDownVerticalOffset="@dimen/dropDownVerticalOffset" />

RecyclerView with onClick and onLongClick implemtation in android example

In the Previous Post, We have create list of items with RecyclerView using appcompat v7.

Now, we have implemented onclick event functionality in the previous post for each list item using stackoverflow link.

Now, I have update the code to latest Android Api RecyclerView default way of implementing
onClick and onLongClick on the each item.


Step 1: Create an Activity with recyclerview

CardViewActivity.java
package com.pratap.cardviews1;

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.Toolbar;

public class CardViewActivity extends AppCompatActivity {

 private Toolbar toolbar;

 private RecyclerView mRecyclerView;
 private RecyclerView.Adapter mAdapter;
 private RecyclerView.LayoutManager mLayoutManager;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  toolbar = (Toolbar) findViewById(R.id.toolbar);

  if (toolbar != null) {
   setSupportActionBar(toolbar);
   getSupportActionBar().setTitle("Android Versions");

  }

  final String[] myDataset = { "Alpha", "Beta", "CupCake", "Donut",
    "Eclair", "Froyo", "Gingerbread", "Honeycomb",
    "Ice Cream Sandwitch", "JellyBean", "KitKat", "LollyPop" };

  mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);

  // use this setting to improve performance if you know that changes
  // in content do not change the layout size of the RecyclerView
  mRecyclerView.setHasFixedSize(true);

  // use a linear layout manager
  mRecyclerView.setLayoutManager(new LinearLayoutManager(this));

   
  // create an Object for Adapter 
  mAdapter = new CardViewDataAdapter(myDataset);
  
  // set the adapter object to the Recyclerview 
  mRecyclerView.setAdapter(mAdapter);

 }

}

Step 2:  Create an Adapter for the recycler with the class RecyclerView.Adapter


CardViewDataAdapter.java

package com.pratap.cardviews1;


import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnLongClickListener;
import android.view.ViewGroup;
import android.widget.TextView;
import android.widget.Toast;

public class CardViewDataAdapter extends
  RecyclerView.Adapter<CardViewDataAdapter.ViewHolder> {
 private static String[] mDataset;

 

 // Provide a suitable constructor (depends on the kind of dataset)
 public CardViewDataAdapter(String[] myDataset) {
  mDataset = myDataset;
  
 }

 // Create new views (invoked by the layout manager)
 @Override
 public CardViewDataAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
   int viewType) {
  // create a new view
  View itemLayoutView = LayoutInflater.from(parent.getContext()).inflate(
    R.layout.cardview_row, null);

  // create ViewHolder

  ViewHolder viewHolder = new ViewHolder(itemLayoutView);
  return viewHolder;
 }

 // Replace the contents of a view (invoked by the layout manager)
 @Override
 public void onBindViewHolder(ViewHolder viewHolder, int position) {

  // - get data from your itemsData at this position
  // - replace the contents of the view with that itemsData

  viewHolder.tvVersionName.setText(mDataset[position].toString());
  
  viewHolder.versionName=mDataset[position];

 }

 // Return the size of your dataset (invoked by the layout manager)
 @Override
 public int getItemCount() {
  return mDataset.length;
 }

 // inner class to hold a reference to each item of RecyclerView
 public static class ViewHolder extends RecyclerView.ViewHolder {

  public TextView tvVersionName;
  
  public String versionName;

  public ViewHolder(View itemLayoutView) {
   super(itemLayoutView);

   tvVersionName = (TextView) itemLayoutView
     .findViewById(R.id.tvVersionName);

   itemLayoutView.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {

     Toast.makeText(v.getContext(), "OnClick Version :" + versionName,
       Toast.LENGTH_SHORT).show();

    }
   });

   itemLayoutView.setOnLongClickListener(new OnLongClickListener() {

    @Override
    public boolean onLongClick(View v) {
     
     Toast.makeText(v.getContext(), "OnLongClick Version :" + versionName,
       Toast.LENGTH_SHORT).show();
     return true;

    }
   });

  }

 }

}

Step 3:

toolbar.xml

<?xml version="1.0" encoding="utf-8"?>

    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimaryDark"
    android:minHeight="?attr/actionBarSize"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light" >

</android.support.v7.widget.Toolbar>

activity_main.xml

    android:orientation="vertical" >

    <include
        android:id="@+id/toolbar"
        layout="@layout/toolbar" />

    <android.support.v7.widget.RecyclerView
        android:id="@+id/my_recycler_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_margin="5dp"
        android:scrollbars="vertical" />

    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    card_view:cardCornerRadius="5dp"
    card_view:cardUseCompatPadding="true" >

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="5dp" >

        <TextView
            android:id="@+id/tvVersionName"
            android:layout_width="match_parent"

            android:layout_centerInParent="true"
            android:gravity="center"
            android:minHeight="55dp"
            android:textColor="@android:color/black"
            android:textSize="24sp" />
    </RelativeLayout>

</android.support.v7.widget.CardView>

Step 5:

<resources>

    <style name="AppTheme" parent="AppTheme.Base" />

    <style name="AppTheme.Base" parent="Theme.AppCompat.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
