ListView with multiple choice

Hi Guys!!

Today i am sharing the code of the multiple choice option select in list view.

ListView is a view group that displays a list of scrollable items. The list items are automatically inserted to the list using an Adapter that pulls content from a source such as an array or database query and converts each item result into a view that's placed into the list. 

For more details about the List View visit the Android Developer site List View.

Lets Start the coding now.

activty_main.xml

MainActivity.java

package com.sunil.listview;

 import android.app.Activity;
import android.os.Bundle;
import android.util.SparseBooleanArray; 
import android.view.View;
import android.widget.ArrayAdapter; 
import android.widget.Button;
import android.widget.ListView;
 import android.widget.Toast;
 
public class MainActivity extends Activity {
 
    ListView myList;
    Button getChoice;
 
   String[] listContent = {
 
            "January",
            "February",
            "March",
            "April",
            "May",
            "June",
            "July",
            "August",
            "September",
            "October",
            "November",
            "December"
 
    };
 
    /** Called when the activity is first created. */
 
    @Override
 
    public void onCreate(Bundle savedInstanceState) {
 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        myList = (ListView)findViewById(R.id.list);
        getChoice = (Button)findViewById(R.id.getchoice);
 
        ArrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_multiple_choice, listContent);
        myList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
 
        myList.setAdapter(adapter);
        getChoice.setOnClickListener(new Button.OnClickListener(){
 

            @Override
            public void onClick(View v) {
             
                String selected = "";
                int cntChoice = myList.getCount();
 
                SparseBooleanArray sparseBooleanArray = myList.getCheckedItemPositions();
                for(int i = 0; i < cntChoice; i++){ 
                    if(sparseBooleanArray.get(i)) { 
                        selected += myList.getItemAtPosition(i).toString() + "\n";
 
                    }
 
                }
 
                Toast.makeText(MainActivity.this, selected, Toast.LENGTH_LONG).show();
 
            }});
 
    }
 
}
