MultiChoice ListView with Custom Adapter

I am writing code for multiple choice list. User easily select multiple item from list after that they can see how many item selected or not. When user will tap on Show Selected Android version easily can get the data in activity.




MainActivity.java

package com.multiplechoicelistview.example;

import android.content.Context;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.Toast;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    private String[] androidVersions = {"Cupcake 1.5", "Donut 1.6 ", "Eclair 2.0", "Froyo 2.2",
            "Gingerbread  2.3", "Honeycomb 3.0", "Ice Cream Sandwich 4.0", "Jelly Bean 4.1",
            "KitKat 4.4", "Lollipop 5.0", "Marshmallow 6.0"};
private  VersionCustomAdapter mVersionCustomAdapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        displayListView();
    }

    /*
    *show ListView
    * */
    private void displayListView() {
        View footerView = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_layout, null, false);
        ArrayList<AndroidVersionName> versionNameArrayList = new ArrayList<>();
        int versionSize= androidVersions.length;
        for (int versionCount = 0; versionCount <versionSize ; versionCount++) {
            AndroidVersionName androidVersionName = new AndroidVersionName();
            androidVersionName.setVersionName(androidVersions[versionCount]);
            versionNameArrayList.add(androidVersionName);
        }
         mVersionCustomAdapter = new VersionCustomAdapter(this, R.layout.version_row_layout, versionNameArrayList);
        ListView listView = (ListView) findViewById(R.id.lvVersionList);
        listView.setAdapter(mVersionCustomAdapter);
        listView.addFooterView(footerView);

        listView.setOnItemClickListener(new OnItemClickListener() {

            public void onItemClick(AdapterView<?> parent, View view,
                                    int position, long id) {
                AndroidVersionName androidVersionName = (AndroidVersionName) parent.getItemAtPosition(position);
                Toast.makeText(getApplicationContext(),
                        "Clicked on Row: " + androidVersionName.getVersionName(), Toast.LENGTH_LONG)
                        .show();
            }
        });
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.btnSelectedList:
                StringBuffer responseText = new StringBuffer();
                responseText.append("Selected Text...\n");

                ArrayList<AndroidVersionName> selectedVersionNameList= mVersionCustomAdapter.getSelectedList();
                int selectedListSize=selectedVersionNameList.size();
                for (int selectedCount = 0; selectedCount < selectedListSize; selectedCount++) {
                    AndroidVersionName androidVersionName = selectedVersionNameList.get(selectedCount);
                    if (androidVersionName.isSelected()) {
                        responseText.append("\n" + androidVersionName.getVersionName());
                    }
                }

                Toast.makeText(getApplicationContext(), responseText,
                        Toast.LENGTH_LONG).show();
                break;
