here is adapter class..... public View getView(final int position, View convertView, ViewGroup parent) { ViewHolder holder=null; Student temp = (Student) getItem(position); if (convertView == null) { convertView = mInflator.inflate(R.layout.item_class_student, null); holder = new ViewHolder(); holder.nameTextView = (TextView) convertView.findViewById(R.id.row_student_name); holder.classTextView = (TextView) convertView.findViewById(R.id.row_student_class); holder.rollNumberTextView = (TextView) convertView.findViewById(R.id.row_student_roll_number); holder.image = (ImageView) convertView

Is there a way to set the selected index of a RadioGroup in android, other than looping through the child radiobuttons and selecting checking the radio button at the selected index? Note: I am populating the Radio Button Group at run time. jjm If your radio group is defined in a layout xml file, each button can be assigned an id. Then you just check a button like this radioGroup.check(R.id.myButtonId); If you created your radio group programmatically (I'm not even sure how you do this...), you might want to consider creating a special layout xml file just for the radio group so that you can

I am making a quiz app in which I have a viewPager which has 15 pages in it having 1 question each and a submit button at the last page.Now I want to get the Maximum number of option selected among 15 questions. Below is my code QuestionPagerFragment.java: public class QuestionPagerFragment extends Fragment { protected View mView; String pageData[]; //Stores the text to swipe. String optionData[];//Stores the option data. int rid; RadioGroup group; String ans; String ans1; String ans2; SharedPreferences prefs; public static final String MyPREFERENCES = "MyPrefs" ; @Nullable @Override public

I've created a radio button in radiogroup, but when I try running the apps all radio button can be selected all the time, and how to set only one radiobutton can be selected at one time? I'm using Fragment RadioGroup radioGroup = (RadioGroup) rootView.findViewById(R.id.RGroup); radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { @Override public void onCheckedChanged(RadioGroup group, int checkedId) { // find which radio button is selected if(checkedId == R.id.Abdominal) { Toast.makeText(getActivity().getApplicationContext(), "choice: A", Toast.LENGTH_SHORT).show()

I know this sound weird so here is the picture. It hold the correct value. The correct radiobutton is (partially) selected. All logic in the OnCheckedChangeListener is executed correctly. I'm completly stunned. Why is the radio button not fully checked? Only thing I can think of is that i'm using Rx2Firebase periodRetriever = FirebaseHelper.getInstance(getContext()).getPeriod() .defaultIfEmpty(0) .distinctUntilChanged() .subscribe(new Consumer<Integer>() { @Override public void accept(@NonNull Integer headerType) throws Exception { getRadioViewChecked(headerType).setChecked(true); } }); EDIT1

From my understanding, to determine if a checkbox is "clicked" and find if it's checked or not, code such as the following can be used: cb=(CheckBox)findViewById(R.id.chkBox1); cb.setOnCheckedChangeListener(this); public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { if (isChecked) { cb.setText("This checkbox is: checked"); } else { cb.setText("This checkbox is: unchecked"); } } However, I am unable to work out the logic on how to do the above for a radiogroup. Here is the xml for my RadioGroup: <RadioGroup android:id="@+id/radioGroup1" android:layout_width="wrap_content
