Save Radiobuttom after selection

Question

Hello, someone could help me in this matter, I have a list with questions in them there are 3 Radiosbuttom for responses, what I want is when the user click the save button, he lists the selected radios and save in a list, the way I managed to do it takes the Radios at the user’s click generating a problem, if the user clicks on another radio of the same position of the list he is saving the two radios that were clicked and keeping in the list that I later picked up and saved in Sqlite.

Follow the layout image.

Follow the Adapter code.

First excuse anything, but I’m typing from the cell phone

From what I understand, your problem is at the moment of adding the Radio you identified that was pressed in your lists (listId, listIDRadio, etc).

Note that you are adding the elements referring to Radiobuttons in the lists within the onCheckedChanged Eventlistener, that is, the code within that method is called every time the Radio that is selected is changed!

To solve this you can set aside the Eventlistener and simply use the method mRadioGroup.getCheckedRadioButtonId(), that returns -1 if no Radio is selected or then returns the Id of the selected button (int)

Also note that if you have ids for each of your Radiobuttons in your layout, you can take this id returned by the function and check if Radio was pressed by its name in the layout:

if(myRadioId == R.id.nome_do_radio){

//Executa algo
}

Again I ask you to excuse me if there is something wrong! I am at 4:40 of a night of insomnia typing in cell phone hehe
