Answer 1

I am posting another answer. Please listen carefully.

1.) Create a global boolean variable :-

    boolean flag = false;

2.)in your getView, do this. This will not check all the checkboxes in your listview. I am assuming that you have only one checkbox in your listview.

    holder.checkBoxinyourListView.setChecked(flag);

3.) Now, in the listener of the checkbox which is NOT in your listview, add this code :-

checkBox not in listView.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            // TODO Auto-generated method stub
            flag = !flag;
            adapter.notifyDataSetChanged();
        }
    });

ScreenShot 1:- When not checked

ScreenShot 2:- When Checked

This Code Works 100%

Answer 3

In the getView(), Add all the position of the checkboxes

ArrayList<Integer> addIndex= new ArrayList<Integer>();//Global
checkedPositions.add(position);

This will contain all the checkboxes position

Use a ArrayList to maintain all the checkbox states in the ListView to keep track of which checkbox is checked with a boolean.

Then when you click on checkAll CheckBox you update all boolean in your list to true and do yourAdapter.notifyDataSetChanged();

ArrayList<Integer> checkedPositions = new ArrayList<Integer>();//Global

Scenario : When Checking individual Checkboxes, adding in array list. The code below is to be added in ListView.setOnItemClickListener()

    final Integer index = Integer.valueOf(position);

    if(!checkedPositions.contains(index))
        checkedPositions.add(index);
    else
        checkedPositions.remove(index);

    check.setChecked(checkedPositions.contains(index));

Scenario 2 : When you check the SelectAll Checkbox.

holder.selectAllCheckbox.setOnCheckedChangeListener() listener

//Write your code here. Write an if condition that matches for the indexes in both the array list i have created and set checked as per your need

Note :- i have used an integer array list. You can use a boolean and do the same steps and the code below:-

if(list.get(position).isChecked()){
    cellHolder.checkBox.setChecked(true);
}
else{
    cellHolder.checkBox.setChecked(false);
}

All the boolean are at true so all the checkBoxes will be checked (the same logic goes for uncheck)

Answer 4

public class Adapter extends ArrayAdapter<TripItem> {
    private final Context context;
    private final ArrayList<CommonExpenseItem> tripExpenseItems;

    public TripsAdapter(Context context, ArrayList<TripItem> values,
            ArrayList<CommonExpenseItem> tripExpenses) {
        super(context, R.layout.expense_list_row, values);
        this.context = context;
        this.tripExpenseItems = tripExpenses;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View rowView = inflater.inflate(R.layout.expense_list_row, parent,
                false);
        return rowView;
    }
}

The above is a simlple custom adapter ,here i am passing values in a arrayList u can pass hashmap simply,

1. Initially load all the string values in a separate hashmap or pojo obj with another value named as checkBox value as "disabled", and set the adapter ,
2. Then in the getView method set the name in the text view and get the checkbox string and check the checkbox if the value is enabled or uncheck if the value is disabled.
3. and also set tag the position to the checkbox, and create oncheckchange listener for the checkbox item inside the getView() and inside that method get the checkbox tag and get the respective hash map or the obj from the arrayList.
4. And Change the chekcbox value as enabled and notify the data set to be changed.
5. Finally for ur problem. once the checkbox in main layout is checked get the arraylist and in a for loop get the hash map or the objs and set the checkbox values to "enabled" and notify dataset changed or set a new adapter and populate in the list view. like wise u can get the solution as u required.
