radio-group

Is there any way of getting an array (or a collection) of the RadioButton s in an Android RadioGroup ? I would like to add individual listeners to radio buttons but I don't see any obvious way of iterating over them. this should do the trick: int count = radioGroup.getChildCount(); ArrayList<RadioButton> listOfRadioButtons = new ArrayList<RadioButton>(); for (int i=0;i<count;i++) { View o = radioGroup.getChildAt(i); if (o instanceof RadioButton) { listOfRadioButtons.add((RadioButton)o); } } Log.d(TAG,"you have "+listOfRadioButtons.size()+" radio buttons"); Why do you need to query the

I have a radio group which I do not want to user to be able to select any of the buttons until a particular checkbox is selected within my app. If the checkbox is unticked then this disables the radio-group. How do I go about doing this. The real trick is to loop through all children view (in this case: CheckBox ) and call it's setEnabled(boolean) Something like this should do the trick: //initialize the controls final RadioGroup rg1 = (RadioGroup)findViewById(R.id.radioGroup1); CheckBox ck1 = (CheckBox)findViewById(R.id.checkBox1); //set setOnCheckedChangeListener() ck1

I have a model returning in the storeLocations object with a isDefault value. if isDefault returns true, I wan't to set that radio button in the group as checked. Not sure if I need to do a $each(data, function(index,value) and iterate through each object returned or if there's an easier way to do this using angular constructs. Object: storeLocations = [ { ... more values, isDefault: true } ] Markup: <tr ng-repeat="location in merchant.storeLocations"> <td>{{location.name}}</td> <td>{{location.address.address1}}</td> <td>{{location.address.address2}}</td> <td>{{location.address.city}}</td> <td

I need to set validation that user must fill / select all details in a page. If any fields are empty wanna show Toast message to fill. Now I need set validation for RadioButton in the RadioGroup. I tried this code but didn't work properly. Suggest me correct way. Thankyou. // get selected radio button from radioGroup int selectedId = gender.getCheckedRadioButtonId(); // find the radiobutton by returned id selectedRadioButton = (RadioButton)findViewById(selectedId); // do what you want with radioButtonText (save it to database in your case) radioButtonText = selectedRadioButton.getText()

I need to have multiple radio button groups in my form like this: I know it's simply done by specifying the same " name " html attribute for each group. HOWEVER MVC doesn't let you specify your own name attribute when using html helper like this: @Html.RadioButtonFor(i => item.id, item.SelectedID, new { Name = item.OptServiceCatId }) Because it looks at each tag's " name " attribute (not " id ") to map/bind the form to the model which the controller receives, etc. Some said that specifying each with the same "GroupName" attribute will solve the problem, but it didn't work either. So, is there
