Checking Multiple Checkboxes in Android

Question

CheckBox checkOne = (CheckBox) findViewById(R.id.checkOne);
checkOne.setSelected(true);

CheckBox checkTwo = (CheckBox) findViewById(R.id.checkTwo);
checkTwo.setSele         


        

Answer 1

If the parent LinearLayout contains only the checkboxes, you can do this:

//ll is the LinearLayout holding the children
for(int i = 0; i < ll.getChildCount(); i++) {
    ((CheckBox)ll.getChildAt(i)).setChecked(true);
}

if you have more views in the LinearLayout you could add a check like this:

for(int i = 0; i < ll.getChildCount(); i++) {
    View v = ll.getChildAt(i);
    if(v instanceof CheckBox) {
        ((CheckBox)v).setChecked(true);
    }
}
