package com.manish.checkboxdemo;

import java.util.Iterator;
import java.util.LinkedHashMap;
import java.util.Map;
import java.util.Set;

import android.app.Activity;
import android.os.Bundle;

import android.widget.CheckBox;
import android.widget.LinearLayout;

public class MainActivity extends Activity {
 LinearLayout linearMain;
 CheckBox checkBox;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  linearMain = (LinearLayout) findViewById(R.id.linearMain);
  /**
   * create linked hash map for store item you can get value from database
   * or server also
   */
  LinkedHashMap<String, String> alphabet = new LinkedHashMap<String, String>();
  alphabet.put("1", "Apple");
  alphabet.put("2", "Boy");
  alphabet.put("3", "Cat");
  alphabet.put("4", "Dog");
  alphabet.put("5", "Eet");
  alphabet.put("6", "Fat");
  alphabet.put("7", "Goat");
  alphabet.put("8", "Hen");
  alphabet.put("9", "I am");
  alphabet.put("10", "Jug");

  Set<?> set = alphabet.entrySet();
  // Get an iterator
  Iterator<?> i = set.iterator();
  // Display elements
  while (i.hasNext()) {
   @SuppressWarnings("rawtypes")
   Map.Entry me = (Map.Entry) i.next();
   System.out.print(me.getKey() + ": ");
   System.out.println(me.getValue());

   checkBox = new CheckBox(this);
   checkBox.setId(Integer.parseInt(me.getKey().toString()));
   checkBox.setText(me.getValue().toString());
   checkBox.setOnClickListener(getOnClickDoSomething(checkBox));
   linearMain.addView(checkBox);
  }

 }

 View.OnClickListener getOnClickDoSomething(final Button button) {
  return new View.OnClickListener() {
   public void onClick(View v) {
    System.out.println("*************id******" + button.getId());
    System.out.println("and text***" + button.getText().toString());
   }
  };
 }

    1. Hi Viral,
      I think if you want remove any item on check then use delete button instead of checkbox. because checkbox use is perform task on selected items not for single item.Anyway its all your logic, do as your requirement.

      1)Add a delete button any where on your layout.
      2)set id for all of your checkbox.
      3)on delete button press get all selected id and remove that row from your list.
      4)if you are using webservice update your server with that deleted item and if local sqlite or any other collection framework just update that.
      5)refill your adapter on notifychange.

      you can check my this post-

  3. Hmmm so very ease just remove arrayList item on check-box clicked. and for getting that potion you can get easily using my multi click demo..
    In your adapter get position and that delete that item from list and update your UI again.

    Thanks!

    1. Why should we answer? You are not a good developer? you can't do it by yourself? Are you paying to us? we are here for helping people who really need help not like you claiming challenges. This is a free web site and I am owner of this web site, if you find anything helpful from here that's good and if not go and find some where else but think ones if someone help you in your code means he is consuming his/her time from their schedule and someone writing blog or answering on stack-overflow you must respect to him/her. If no one share their knowledge you will struggle. Hope you can understand now. Best of luck and your comment is not an issue for me i can delete in a minute but i don't care what you are writing and why.

      And still you have any doubt let us do have a deal pay $250 for my time I will give your solution. And if not I will pay you $500.

    1. Please check here-

      View.OnClickListener getOnClickDoSomething(final Button button) {
      return new View.OnClickListener() {
      public void onClick(View v) {
      System.out.println("*************id******" + button.getId());
      System.out.println("and text***" + button.getText().toString());
      }
      };
      }


      OnCheckBox selected you will get a ID in logcat. It is not last one.
