Android RadioButton not able to unset using setChecked(false) method

Question

If I set a radio button to be selected on the first time, it works fine. But if I unselect it by calling ((RadioButton) findViewById(R.id.ID)).setChecked(false); then, later even if I try to make it selected by calling setChecked(true) will not work unless the user select it from the screen.

Have any one come across this? or is it only me?

        if(Val != null){
        if( ((RadioButton) findViewById(R.id.ID1)).getText().toString().trim().equals(Val))
        ((RadioButton) findViewById(R.id.ID1)).setChecked(true);
        else if(((RadioButton) findViewById(R.id.ID2)).getText().toString().trim().equals(Val))
        ((RadioButton) findViewById(R.id.ID2)).setChecked(true);
        }
        else {
            ((RadioButton) findViewById(R.id.ID1)).setChecked(false);
            ((RadioButton) findViewById(R.id.ID2)).setChecked(false);
        }

If the else part is executed atleast once then everything gets mess up. When I step thro my debugger, I can see the execution goes in the correct path and setting it to true. It is getting executed only once, I checked that. And I am not resetting it back to false in any other part of the code.

Could we see your sourcecode ? – Clothesline

I tried this android:saveEnabled="false", after going thro groups.google.com/group/android-developers/browse_thread/thread/… , but that didnt help me. Wow atleast I am not alone... – Mantellone

Have the same Problem and while my layout is Image - Text - Check Image - Text - Check i can not make only one RadioGroup ... i found that it is a 'bug' when i can not set the Radio with setChecked(false) what the android-developer must do unfix. Thanks for your info, will try it ... – Egg

Your Welcome. Did that work for you? – Mantellone

Answer 1

I found the solution.

It is not possible to uncheck a particular radio button. You can only set the other item to true.

So to clear all the checked items, you should call the clearcheck() method on the RadioGroup.

So my else part is

        else {
            ((RadioGroup) findViewById(R.id.ID0)).clearCheck();
        }

Exactly what I needed! It gets really messy with radio buttons sometimes. Thanks! – Arin

Or in my case it got clearer when I took off RadioGroup and played with two RadioButtons. – Terrellterrena

This solved my issue. I was trying to recheck the already checked radio button which shwoing it as unchecked in UI. – Tsana

Answer 2

Take one invisible radio button and check it. All other radio buttons of group will be unchecked automatically..
