Add onClick Action Listener for dynamically created CheckBox

Question

I am creating CheckBoxes Dynamically in an Android Class (Not Activity). So I need to add onClick Action Listener to my checkboxes, how to implement this.

I am using following code.

public class DataBaseAdapter extends SQLiteOpenHelper
{
    ...//onCreate and onUpdate
    ...
    ...
    public TableLayout getAllAlarmList(Context con)
    {
            TableLayout tb = new TableLayout(con);
            TableRow[] tr = new TableRow[maxCount]; //maxCount is the number of rows 
            CheckBox[] check = new CheckBox[maxCount]; //maxCount is the number of rows in the database.
            for(int i=0;i<maxCount;i++)
            {
                tr[i]=new TableRow(con);
                check[i]= new CheckBox(con); //con is Context class passed as argument.
                check[i].setText(Integer.toString(i));
                check[i].setId(100+i);
                // I have to add onClick Action Listener here.
                tr[i].addView(check[i]);
                tb.addView(tr[i]);
            }
            return tb;
    }

}

For this I am also keeping a track of the ids of the checkboxes.

because it is not an Activity class so, unable to write check[i].setOnCheckedChangeListener(new onCheckedChangeListener) as the class do not extend View Class — Sharda Singh

you can also set any Listener to Views from non-activity class. try it as :

check[i].setId(100+i);
check[i].setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

   @Override
   public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {

      switch(buttonView.getId()) {
        case R.id.checkbox_meat:
         // do your code here...
          break;
        case R.id.checkbox_cheese:
         // do your code here...
          break;
       // TODO: Veggie sandwich
      }

   }
});

@ShardaSingh : ok first remove android:onClick="onCheckboxClicked" from all Checkbox xml .

Sharda Singh Over a year ago

checkboxes are there dynamically.. so no chance of onCheckboxClicked, in xml

Sharda Singh Over a year ago

The checkboxes are created dynamically so the previous checkbox has no record for the coming checkbox, and its id.
