Question

I am getting the following two errors located in my code below (CheckBox) v.isChecked();:

Type mismatch: cannot convert from CheckBox to boolean

The method isChecked() is undefined for the type View

for(final int i = 0; i < setOfCheckBoxes.length; i++){

                                                setOfCheckBoxes[i].setOnClickListener(new View.OnClickListener(){    
      public void onClick(View v) {      
     selected[i] = (CheckBox) v.isChecked();
     }
   });
 }

Not sure what I am doing wrong and if anyone has any ideas please let me know.

Thanks!

Answer 1

Method calls bind tighter in order of operations than casts. Try this:

selected[i] = ((CheckBox) v).isChecked();

Edit: Regarding the use of ‘i’ in the inner class, use a separate variable for the captured index and the loop iteration. Try this:

for (int i = 0; i < setOfCheckBoxes.length; i++) {
    final int index = i;
    setOfCheckBoxes[i].setOnClickListener(new View.OnClickListener(){    
        public void onClick(View v) {      
            selected[index] = ((CheckBox) v).isChecked();
        }
    });
}
