How to prevent a CheckBox from being checked?

Question

I would like to be able to prevent a CheckBox from being selected (or to set it back to unselected), when the CheckBox is clicked

How can I achieve this?

I do not want to simply disable the checkbox. I want the user to think it is checkable, but when the user tries to check it... then I will (possibly) prevent the checkbox from being checked and display a message.

Answer 1

Just add the android:clickable="false" attribute in the layout xml.

So for me I have:

    <CheckBox         android:id="@+id/server_is_online"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:checked="true"         android:clickable="false"         android:text="@string/server_is_online"         android:textSize="23sp" /> 

and it works fine.

No that's probably not how you're supposed to use a checkbox, but I am using this as a dirty hack in the prototyping stage in lieu of having a nice icon with a green tick for all good, and an evil red cross for end of the world :)

Answer 2

you can do something like this:

cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){      @Override     public void onCheckedChanged(CompoundButton buttonView,     boolean isChecked) {     if(isChecked){         cb.setChecked(false);         // Code to display your message.         }     } });
