How do I get all the selected list Items using Checkbox

Question

I am using Checkbox with each and every list item, and now i would like to get name of all the selected list items on button click.

I have posted code of Adapter and Activity class as well, because later i have to show selected list items into another activity into ListView.

But for now i just want to see all the selected list items on button click

Adapter:

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        // convert view = design
        ....................

        holder.tvName.setText(actorList.get(position).getName());           

        holder.checkBox.setOnCheckedChangeListener(null);

        holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if(isChecked){
                    // add into arraylist
                  selectedname.add(actorList.get(position).getName());
                }else{
                    // remove from arraylist
                    selectedname.remove(actorList.get(position).getName());
                }

            }
        });

        return v;

    }

The below code working fine for me so you can try this

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/select_btn"
    android:text="Select"/>

<ListView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/listview"/>

list_row.xml

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

This may helps you.

ArrayList<String> selectedname  = new ArrayList<String>();

@Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        // convert view = design
        View v = convertView;
        if (v == null) {
            holder = new ViewHolder();
            v = vi.inflate(Resource, null);

            holder.tvName = (TextView) v.findViewById(R.id.textView1);          
            holder.checkBox = (CheckBox) v.findViewById(R.id.cbBox);

            v.setTag(holder);
        } else {
            holder = (ViewHolder) v.getTag();
        }

        holder.tvName.setText(actorList.get(position).getName());  
       checkbox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if(isChecked){
                    // add into arraylist
                  selectedname.add(actorList.get(position).getName());
                }else{
                    // remove from arraylist
                    selectedname.remove(actorList.get(position).getName());
                }

            }
        });

        return v;

    }

    static class ViewHolder {

        public TextView tvName; 
        public CheckBox checkBox;

    }

pass this selected selectedname List to another activity. on Button Click pass List between Activity like

hey bro i am using your way, i just updated my code check above but still i don't know that how can i show all checked list of items on button click – Oreo Jul 09 '15 at 10:04
can you pls check line In Button click ArrayList mselectedname = adapterObject.selectedname; – Ankitkumar Makwana Jul 09 '15 at 10:08
you can get it from ServiceAdapter adapterObject = new ServiceAdapter(your needed data pass here); – Ankitkumar Makwana Jul 09 '15 at 10:09
bro sorry but still not getting how do i show all selected items (into another activity as well) using click on button – Oreo Jul 09 '15 at 10:11
See in your Button click first you need to get Selected List item name, then you need to pass that list to second Activity which you needed, according that selected list item names, you can display list. – Ankitkumar Makwana Jul 09 '15 at 10:14

I have used System.out.println(selectedname.size()); to know the size of list item, but i don't know how do i get name of selected list items on button click, can you just show me this thing ? – Oreo Jul 09 '15 at 10:16
ArrayList mselectedname = adapterObject.selectedname; – Ankitkumar Makwana Jul 09 '15 at 10:17

create new arraylist and insert checkbox item into it

ArrayList<String> checkedSelection = new ArrayList<String>();


    holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    if(isChecked){
                        // add into arraylist
                           checkedSelection.add(holder.checkBox.getText().toString());
                    }else{
                        // remove from arraylist
                         checkedSelection.remove(position);
                    }
                }
            });

and on button click send arraylist to another activity and load listview

below your this line holder.tvName.setText(actorList.get(position).getName()); – Abhijeet Jul 09 '15 at 09:36
check my updated code and let me know where i have to make changes – Oreo Jul 09 '15 at 09:53
Instead of holder.checkBox.setOnClickListener(new OnClickListener() { You have to use holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() { – Abhijeet Jul 09 '15 at 09:55
i have updated my code, and how do i show list of items on button click – Oreo Jul 09 '15 at 09:58
Either you can create a static Arraylist checkedSelection in MainActivity then add or remove items in checkbox selected item as MainActivity.checkedSelection.add() or MainActivity.checkedSelection.remove() and send to another activity in Intent as toOtherActivity.putStringArrayListExtra("selected_list", checkedSelection); or store it in shared preference and get that into another activity – Abhijeet Jul 09 '15 at 10:11

For this do as below

Im MyAdapter create class level variable

public boolean[] checked;

and write onCheckedChanged event

@Override
public void onCheckedChanged(CompoundButton buttonView,
   boolean isChecked) {
checked[position] = select.isChecked();
}

Now you can access boolean array as below

ListAdapter adapter = listView.getAdapter(); 
boolean[] check =((MyAdapter) adapter).checked;

Now you can extract checked items

Hope this is useful

Edit:

Below the line

holder.checkBox = (CheckBox) v.findViewById(R.id.cbBox);

Add listener like this

holder.checkBox.setOnCheckedChangeListener(new    CompoundButton.OnCheckedChangeListener() {
  @Override
  public void onCheckedChanged(CompoundButton buttonView,
      boolean isChecked) {
      checked[position] = select.isChecked();
  }
});

For this you have to maintain the Checkbox value in the Actor bean class

I have updated your getView() method of your adapter class.Have a look.

@Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        // convert view = design
        View v = convertView;
        ViewHolder holder;
        if (v == null) {
            holder = new ViewHolder();
            v = vi.inflate(Resource, null);
            holder.tvName = (TextView) v.findViewById(R.id.textView1);
            holder.checkBox = (CheckBox) v.findViewById(R.id.cbBox);
            v.setTag(holder);
        } else {
            holder = (ViewHolder) v.getTag();
        }
        holder.tvName.setText(actorList.get(position).getName());
        holder.checkBox.setOnCheckedChangeListener(null);
        holder.checkBox.setChecked(actorList.get(position).getStatus());
        holder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                actorList.get(position).setStatus(isChecked);
            }
        });
        return v;
    }

Make sure to add the getStatus() and setStatus(boolean) to your bean class.

Best way to do this is:

Make a Model with a Boolean isChecked as a property

public Class CheckModel{
    String name;
    Boolean isChecked;

    public CheckModel(String name,Boolean isChecked){
        this.name = name;
        this.isChecked = isChecked;
    }

    //setter and getter here

}

While adding the model into arraylist set isChecked to false as default

 arrayList.add(new CheckModel("title",false));

now in getView() function in Adapter change the isChecked property to true onChecked

arrayList.get(position).setChecked(true);

Lastly when you want name of all the Checked Items do this

for(int i = 0; i<arrayList.size;i++){
    if(arrayList.get(i).getisChecked()){
        //retreive the name
    }else{
        //ignore
    }
}

How do I get all the selected list Items using Checkbox
