Uncheck all RadioButton in a RadioButtonGroup

Question

What I wanted to achieve is this: Right after the activity starts, I want that no RadioButton is selected/checked.

My problem is this: When the activity starts, the first RadioButton is always selected/checked.

I tried radioButton1.setChecked(false) right after initialization of the radiobutton(inside onCreate), but when the activity starts, I can't manually check/select the first radiobutton. Till I select the 2nd or 3rd radio button, I can now select/check the first radio button.

Solution 1

RadioGroup radioGroup = (RadioGroup)findViewById(R.id.radiogroup);
radioGroup.clearCheck();

Solution 2

use clearCheck() for clearing all checked radiobutton when acticity is started or resumed

 @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
 RadioGroup rg=(RadioGroup)findViewById(R.id.RG);
rg.clearCheck();
}
@Override
protected void onResume() {  
RadioGroup rg=(RadioGroup)findViewById(R.id.RG);
rg.clearCheck();  
super.onResume();  
    }  

Solution 3

use this

RadioButton spec1=findViewById(yourRadioGroup.getCheckedRadioButtonId());
        if (spec1.isChecked())
        {
            spec1.setChecked(false);
        }

As far I know, there is no class named "RadioButtonGroup". Instead of this, the appropriate class name is "RadioGroup". Beyond this tiny fact, the above codes are precisely workable!.

what if we want to do that in OnCheckedChangeListener ?? for future question why do you do that i have different type views in radio grp in addition to radio btn !

Is there a way to do that without the wacky unchecking animation?
