Radio Button Selection in Android

Question

Thank you!!!

Answer 1

Its too simple. Earlier you mentioned that first time your first radio button is selected then at that time you have to just set visibility for checkboxes visible. Like

 ch1.setVisibility(View.VISIBLE); // same for other checkboxes

And when you select second radio button at that time set visibility for that check boxes GONE. Like

 ch1.setVisibility(View.GONE);   // same for other checkboxes

UPDATE:

 radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {

    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {
        // TODO Auto-generated method stub
        if(checkedId == R.id.urfirstR1)
          {
                ch1.setVisibility(View.VISIBLE);

       else if(checkedId == R.id.ursecondr2)
          {
                ch1.setVisibility(View.GONE); 
          }
    }
});

Try this

radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {

@Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {

      if(checkedId == R.id.firstradiobutton)
               {
                 // visible all checkbox here
              }

       else if(checkedId == R.id.secondradiobutton)
              {
                  // invisible all checkbox here
              }
        }
    });

Try below solution.

By default you don't have to do anything. and onCheckchangelistener use below code.

radiobutton2.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            ch1.setVisibility(View.INVISIBLE); 
           ch2.setVisibility(View.INVISIBLE); 
          ch3.setVisibility(View.INVISIBLE); 
        ch4.setVisibility(View.INVISIBLE); 
        }
    });

Put this inside your onCreate method. and replace ID name of checkboxes and radio button's as per your ID names.
