How to manage onclick on dyanamically generated checkbox in android

I have created multiple checkboxes via applying looping.

for(int l=0;l<len;l++)
{
chkBox = dynamicUiComponents.myCheckBox(context, new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT), 100+i, "Unchecked", opts[l]);
myLayout.addView(chkBox);
}

All the check boxes are showing. But when I am applying setOnCheckedChangeListener(l) on that check box, then only last added check box text is printer. Its because every time in loop, I provide a new object reference to the chkBox variable. So here how to identify that which chechbox is clicked.

You can set a different tag for each Checkbox and set the listener on THIS, you activity should implement the listener and then do whatever you want when the event is trigger.

Try the following

for(int l=0;l<5;l++) 
{ 
    chkBox = new CheckBox(context); 
    myLayout.addView(chkBox); 
    chkBox.setTag(""+l);
    chkBox.setOnCheckChangeListener(new ...(){   
        int x = Integer.ValueOf(chkBox.getTag());
        //do whatever you want to do here
    });
}

In your code, you did not create an array of CheckBoxes, you only created one. So, using setOnCheckChangedListener(I) will not refer to the checkBox. Either you set the listener inside the loop, or give each a unique ID to refer to it later and set the listener:

for(int l=0;l<5;l++) { chkBox = new CheckBox(context); 
chkBox.setOnCheckChangedListener(
//your implementation
);
myLayout.addView(chkBox); }

you can add id to tag:

for(int id=0;id<5;id++) { 
 chkBox = new CheckBox(context);
 chkBox.setTag(id); 
 myLayout.addView(chkBox); 
}

and you may use:

Integer i = (Integer) chkBox.getTag();
