Question

I got a program that has 50+ checkboxes on one page.
And I need to check which boxes are selected.

I know I can do somehting like this:

CheckBox cb1 = (CheckBox) findViewById(R.id.checkBox1);
CheckBox cb2 = (CheckBox) findViewById(R.id.checkBox2);

if (cb1.isChecked){
//get Checkbox name
}
if (cb2.isChecked){
//get Checkbox name
}

But if I have to do this with more then 50 checkboxes, that would take some time.
Is their a faster way to check which on is selected? Something like:

int i;

for (i = 0; i<checkBox.length; i++){
  CheckBox cb+i = (CheckBox) findViewById (R.id.checkBox+i);

     if (cb+i.isChecked){
     //get Checkbox name
     }
}

Maybe also good to say: you can select more then 1 checkbox.
I hope you know what I mean.

Thanks already,

Another workaround may be:

Suppose you have added CheckBox in LinearLayout and you can get the LinearLayout reference in Java and get the child Views like this:

LinearLayout layout= (LinearLayout)findViewById(R.id.checkbox_container);
ArrayList values = new ArrayList();
for(int i=0; i<layout.getChildCount(); i++)
{
    View v = layout.getChildAt(i);
    if(v instanceof CheckBox)
    {
        CheckBox cb = (CheckBox)v;
        if(cb.isChecked())
        values.add(cb.getText().toString());
    }
}
