i want to make a questionnaire with Android Studio. Each question can be answered with yes or no. The problem is, that i have some follow-up questions (f.e. if question 1 answered with yes, then i have 3 follow-up questions to answer). Maybe it is important to know, that there are only follow-up questions if the user is clicking on the yes Button for some questions (there are never follow-up questions if he is clicking no)
I am an absolute beginner, so tell me if you have other ideas to solve this problem.
My idea is to make a custom listview and if the user is clicking on the first answer, i want to update the list and add questions if they are needed now (would be ok if the new questions are getting to the end of the list).
That's my Code till now:
questions_activity.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/questionsListView"
android:layout_alignParentEnd="true"
android:layout_alignParentTop="true"
android:descendantFocusability="blocksDescendants"/>
</RelativeLayout>
itemView.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Medium Text"
android:id="@+id/question"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<RadioGroup
android:orientation="horizontal"
android:id="@+id/radioGroup"
android:layout_width="match_parent"
android:layout_height="20dp"
android:layout_alignParentEnd="true"
android:layout_below="@+id/question">
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Yes"
android:id="@+id/yesButton"
android:layout_marginLeft="135dp" />
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="No"
android:id="@+id/noButton"
android:layout_marginRight="50dp"/>
</RadioGroup>
</RelativeLayout>
LoggedInActivity.java:
public class LoggedInActivity extends Activity {
public List<Questions> myquestions = new ArrayList<Questions>();
public List<Integer> answerList = new ArrayList<Integer>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.questions_activity);
populateQuestions();
populateListView();
registerClickCallback();
}
private void registerClickCallback(){
ListView list = (ListView) findViewById(R.id.questionsListView);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View viewClicked, int position, long id) {
boolean clickedQuestion = myquestions.get(position).getAnswer();
}
});
}
private void populateQuestions() {
myquestions.add(new Questions("Question1"));
myquestions.add(new Questions("Question2"));
myquestions.add(new Questions("Question3"));
}
private void populateListView() {
ArrayAdapter<Questions> adapter = new MyListAdapter();
ListView list = (ListView) findViewById(R.id.questionsListView);
list.setAdapter(adapter);
}
private class MyListAdapter extends ArrayAdapter<Questions> {
public MyListAdapter() {
super(LoggedInActivity.this, R.layout.item_view, myquestions);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View itemView = convertView;
if (itemView == null) {
itemView = getLayoutInflater().inflate(R.layout.item_view, parent, false);
}
Questions currentQuestion = myquestions.get(position);
TextView question = (TextView) itemView.findViewById(R.id.question);
question.setText(currentQuestion.getQuestion());
RadioGroup answers = (RadioGroup) itemView.findViewById(R.id.radioGroup);
return itemView;
}
}
The OnClickListener doesn't work at all. I know, i need to do something with the RadioGroup in getView, but i don't know how (already tried to progress with solutions from here(Customized ListView with TextView, TextView, RadioGroup in Android) but it doesn't worked.
Is it even possible to add new questions and delete them if he is changing his opinion or are there better solutions?
