I have the function that display a RingTone list from User's phone as a RadioGroup inside RecyclerView
The RadioGroup's size increase dynamically as the size of user's phone
Everything work perfectly except when user select a ringtone, click save and then go back again, it doesn't show the Ringtone that has been selected
How can I get the index/id of the radio button from a dynamic RadioGroup?
on that radiobutton listener like oncheckedchangelistener get it's id and save it. After that when screen's oncreate fetch that id and set selected.
One more thing in model class set one boolean variable which define radio button checked or not.

I'm building an ExpandableListView in which there are groups of radio buttons.
Currently, I am able to handle the click event on each radio button and select the corresponding one and deselect the others. But there is just one more thing needed to make it perfect. That is displaying the value of the selected checkbox in the group view so the user can see what is selected without expanding it.
For that purpose, I have a TextView in the group view. Is it possible to update that TextView when a checkbox is selected in the child view?
Here is a screenshot of what I have right now:
Basically what I want to accomplish is to make it write the value of the selected checkbox instead of "Regular".
Thanks.
in your example, it seems perfectly reasonable to save a reference to your TextView inside a member variable when it is created. you can then easily update its value by calling setText() on it from within your checkbox's click handler.
it is neither necessary nor desirable to call notifyDataSetChanged().
I am working on an Android application where I want a user to select a RadioButton corresponding to one category, and add a spinner within the same layout, where the displayed spinner depends on the radio button that was selected. This means for each RadioButton I have a different spinner. I know how to add view to the layout but I was wondering how I might go about storing each of the individual spinners and requesting them when the corresponding category is selected. Is it possible to store them within a layout activity and select the correct one using findViewById?
Agree to Trushit
add all the spinners in the view & on performing the Radio Button event set the visibility of the spinners.
yourSpinner.setVisibility(View.VISIBLE);
&
yourSpinner.setVisibility(View.GONE);
I use onCheckedChangeListener to return the result back to MainActivity and finish the current activity. But if user decides to use the default selected value, he'd like to re-click the radiobutton to save result. How can I do that?
Thanks
Edit:
In short, how do I know if a user selects an already selected radiobutton?
If user selects the selected value then nothing changes and this method won't get called but you can check whenever you want that which radio button in a radio group is selected it should work.
If you want to check whether user has selected a different option just compare the current selection with default selection.
I have list which contain checkbox in each list and I want to define these checkbox for only one of check box can select (like radio button) anybody have any ideas?
Set clickable/focusable/focusableInTouchMode to false, and then the list item vill receive the click, then set the checkbox state manually.
If the checkbox is clickable, then the item will not receive any event, this is an old Android bug still not fixed. Even worse if you want to use EditTexts, but don't get me there
I have a static radiogroup in my XML layout, but I have created all of the radiobuttons dynamically as an effect of user input. Since none of these have ID's, is there a way I can call a method on a whole radiogroup to just return the text (or label) of the checked radio button? All the labels are URL's so if I can get the URL of the checked radio button then I can pass it to a method i created to open the web browser.
I can use ID's but then I would have to create a bunch of extra text for the radio button labels anyways, then a bunch of if statements with the labels written a second time.. [ if this ID is selected go to this URL, if this ID is open go to this URL...] Where as I just want to take the RadioButton's label and just put it right into the browser method.
I found this post: Android: How to get text of dynamically created radio button selected by the user?
but it wasn't answered correctly.
Thanks in advance.
If IDs are no good for you, maybe you should use the tag property that all Views have, i.e. call radioButton.setTag(url) when you create the button. Then call View.getTag() in your onClickListener and cast to a String to get your URL back.
