Android survey app with multiple viewholders and viewpager

in my app I'm creating a survey with multiple question types like radio button, checkboxes, dropdown, photo, stars, textbox. Survey has a number of pages and for this case I'm using a viewpager.
Radio buttons and checkboxes are generated dynamically, questions can have a comment field and some them can have optional fields.
In each page I have a recyclerview where I display types of questions. The problem is when I want to save the data, it is not working. Now I have an adapter for ViewPager and another one for recyclerview. In each view holder of recyclerview I have to save the data to Sqlite database when I click finish button in the viewpager. I'm trying to use an interface to communicate but the data are not saved correctly.
Here what I have on my viewpager adapter:
public class SurveyPagerAdapter extends PagerAdapter {
private final List<RecyclerView> mViews;
private final List<Page> mPages;
private final Context mContext;
private final AppCompatActivity mActivity;
private final ViewPager viewPager;
// ArrayList<SurveyListLines> surveyLinesList;

I'm looking to find a right way how to implement the survey, I'm doing some research which of design patterns can fit for this kind of application. The only problem is to manage the send button from ViewPager, the user interface is fine. If anyone have some suggestions about this I would be glad to hear.
Thanks in advance.

How to manage multiple positions in RecyclerView OnClickListener

I want to know how I can get access to other elements of the array in this onclicklistener for a Recycler view. Specifically, I want to be able to change the enabled state of a position other than the current Listener position, but within the click event.
I'm trying to make it such that if three colors are checked (those are check boxes) every box not checked will be disabled until the number of boxes checked is < 3.
The for-loops I have I wrote make sense, but I can't programmatically change the enabled state within the onClickListener for some reason.
private void buildRecyclerView() {
mRecyclerView = findViewById(R.id.recyclerView);
mRecyclerView.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(this);
mAdapter = new ExampleAdapter(mExampleList);
mRecyclerView.setLayoutManager(mLayoutManager);
mRecyclerView.setAdapter(mAdapter);
mAdapter.setOnItemClickListener(new ExampleAdapter.OnItemClickListener() {
#Override
public void onItemClick(int position) {
boolean checkedState;
if (mExampleList.get(position).getChecked1() == false) {
checkedState = true;
} else {
checkedState = false;
}
changeItem(position, checkedState);
int sum = 0;
for (int i = 0; i < stringArray.length; i++) {
Boolean checked = mExampleList.get(i).getChecked1();
if (checked == true) {
sum = sum + 1;
}
}
for (int i = 0; i < stringArray.length; i++) {
Boolean checked = mExampleList.get(i).getChecked1();
if (!checked && sum == 3) {
mExampleList.get(i).setEnabled1(false);
} else {
mExampleList.get(i).setEnabled1(true);
}
}
}
});
}
adapter
public class ExampleAdapter extends RecyclerView.Adapter<ExampleAdapter.ExampleViewHolder> {
private ArrayList<ExampleItem> mExampleList;
private OnItemClickListener mListener;
public interface OnItemClickListener {
void onItemClick(int position);
}
public void setOnItemClickListener(OnItemClickListener listener) {
mListener = listener;
}
public static class ExampleViewHolder extends RecyclerView.ViewHolder {
public CheckBox mCheckBox;
public ExampleViewHolder(#NonNull View itemView, final OnItemClickListener listener) {
super(itemView);
mCheckBox = itemView.findViewById(R.id.checkBox);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (listener != null){
int position = getAdapterPosition();
if (position != RecyclerView.NO_POSITION);
listener.onItemClick(position);
}
}
});
}
}
public ExampleAdapter(ArrayList<ExampleItem> exampleList) {
mExampleList = exampleList;
}
#NonNull
#Override
public ExampleViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.example_item, parent, false);
ExampleViewHolder evh = new ExampleViewHolder(v, mListener);
return evh;
}
#Override
public void onBindViewHolder(#NonNull ExampleViewHolder holder, int position) {
ExampleItem currentItem = mExampleList.get(position);
holder.mCheckBox.setText(currentItem.getCheckText());
holder.mCheckBox.setEnabled(currentItem.getEnabled1());
holder.mCheckBox.setChecked(currentItem.getChecked1());
}
#Override
public int getItemCount() {
return mExampleList.size();
}
}
Item Class
public class ExampleItem {
public String mCheckText;
public Boolean mEnabled;
public Boolean mChecked;
public ExampleItem(String mCheckText, Boolean mEnabled, Boolean mChecked) {
this.mCheckText = mCheckText;
this.mEnabled = mEnabled;
this.mChecked = mChecked;
}
public ExampleItem(String mCheckText) {
this.mCheckText = mCheckText;
}
public String getCheckText() {
return mCheckText;
}
public void setCheckText(String mCheckText) {
this.mCheckText = mCheckText;
}
public Boolean getEnabled1() {
return mEnabled;
}
public void setEnabled1(Boolean mEnabled) {
this.mEnabled = mEnabled;
}
public Boolean getChecked1() {
return mChecked;
}
public void setChecked1(Boolean mChecked) {
this.mChecked = mChecked;
}
}
In other words, I am trying to make everything below blue disabled until I uncheck Red, Green, or Blue!

Try the following:
In adapter, add below codes:
private int selectedCount = 0;
public int getSelectedCount() {
return selectedCount;
}
public void setSelectedCount(int selectedCount) {
this.selectedCount = selectedCount;
notifyDataSetChanged();
}
and change onBindViewHolder() to:
#Override
public void onBindViewHolder(#NonNull ExampleViewHolder holder, int position) {
ExampleItem currentItem = mExampleList.get(position);
holder.mCheckBox.setText(currentItem.getCheckText());
holder.mCheckBox.setChecked(currentItem.getChecked1());
if ((selectedCount == 3)) holder.mCheckBox.setEnabled(currentItem.getChecked1());
else holder.mCheckBox.setEnabled(true);
}
Then in Activity/Fragment, change mAdapter.setOnItemClickListener(new ExampleAdapter.OnItemClickListener()... to:
mAdapter.setOnItemClickListener(new ExampleAdapter.OnItemClickListener() {
#Override
public void onItemClick(int position) {
boolean checkedState;
int selectedCount = mAdapter.getSelectedCount();
if ((selectedCount != 3) || (mExampleList.get(position).getChecked1())) {
if (mExampleList.get(position).getChecked1() == false) {
checkedState = true;
selectedCount++;
} else {
checkedState = false;
selectedCount--;
}
changeItem(position, checkedState);
mAdapter.setSelectedCount(selectedCount);
}
}
});
Pls note that no need to have mEnabled field in the ExampleItem class. Hope that helps!
Explanantion:
About the onClick:- This is because CheckBox totally covered the layout, so itemView cannot recieve the click event. About RecyclerView:- The idea is simple, after modified the data set [not list, here I refer to the mExampleList and also the selectedCount], then call notifyDataSetChanged() which will redraw all recycler item views.

You would need to create a setter function for your 'mExampleList' in your Adpater class, to update the dataset that the adapter is using. It obviously does not change anything, if you make changes to 'mExampleList' in your activity, without updating the list used by the Adapter.
So at the end of your click listener you would have something like that:
mAdapter.setExampleList(mExampleList)
mAdapter.notifyDataSetChanged()

Multiple selected items are not staying highlighted

When i choose an item from listview, it turns gray but when I select another item in the listview then the previous highlighted item turns to default color and the new item turns to gray. What I want is to stay both of them to be highlighted, and when a click on the highlighted items they should turn back to normal as well.
My code:
listView = (ListView) findViewById(R.id.conversationList);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
listView.setMultiChoiceModeListener(new conversationsMultipleChoiceListener());
listView.setAdapter(conversationsAdapter);
((ConversationsAdapter) conversationsAdapter).updateConversations(conversationsList);
listView.setLongClickable(true);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Conversation item = (Conversation) conversationsAdapter.getItem(position);
startChat(item, false);
}
});

#Override

Listview xml:
<ListView

android:layout_marginRight="10dp"
android:divider="#android:color/transparent"
android:dividerHeight="7.0sp"
android:scrollbars="none"
android:listSelector="#drawable/conversations_selector"></ListView>
How can i achive that functionality?

First, add a field conversationSelected in the Conversation class.
You should useRecyclerView instead of ListView.
You can refer to the official documentation to get started with RecyclerView.
When you have your RecyclerView, you can define the Adapter in this way:
public class ConversationAdapter extends RecyclerView.Adapter<ConversationAdapter.ViewHolder> {
List<Conversation> conversations;
public ConversationAdapter(List<Conversation> conversations) {
this.conversations = conversations;
}
public ConversationAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
// create a new view
TextView v = (TextView) LayoutInflater.from(parent.getContext())
.inflate(R.layout.item_view, parent, false);
...
MyViewHolder vh = new MyViewHolder(v);
return vh;
}
// Replace the contents of a view (invoked by the layout manager)
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Conversation conversation = conversations.get(position);
holder.mTextView.setText(conversation.getConversationText());
}
// Return the size of your dataset (invoked by the layout manager)
#Override
public int getItemCount() {
return conversations.size();
}
public static class MyViewHolder extends RecyclerView.ViewHolder {
// each data item is just a string in this case
public TextView mTextView;
public MyViewHolder(TextView v) {
super(v);
mTextView = v;
}
}
Next step: add item click listener to the RecyclerView: I struggled a little bit before see this answer which helps me to solve the problem: RecyclerView click Listener
In the clickListener you have to change the state conversationSelected of the Conversation in the conversations list (not inside the ViewHolder) to true.Then when you need to retrieve the selected conversation you have only to check this value.

SetExpandAdapter in RecycleViewAdapter

I have RecycleView List with an ExpandableLinearLayout ( i use a third party library). In my ExpandableLinearLayout I have a ListView, with an custom ArrayAdapter.
I set my Adapter in the RecycleViewAdapter and submit one ArrayList that contains 4 ArrayLists and the position from the onBindViewHolder() method , too fill the different sections in the RecycleView.
I pass the data in the correct section but i get only the first element of each ArrayList. I Log some stuff and the problem is the position from the getView method in my ArrayAdapter is always 0..
I search and played around a bit but i didnt found a solution.. I hope somebody can help..

Set Radiobutton true onItemclick on listview

final RadioButton itemcheck = (RadioButton) item_view
.findViewById(R.id.listview_radiobutton);
if (itemcheck.isChecked()) {
itemcheck.setChecked(true);
} else {
itemcheck.setChecked(false);
}
itemcheck.setChecked(true);
}

}
public interface OnCheckedRadioButon {
void onCheckedButton(Details pr);
}
class ViewHolder {
RadioButton radiobutton;
TextView listview_name;
}
}
It is working but if I click on another position of the listview then the previous radiobutton position is not unchecked.I want to uncheck all the previous ones and mark only one at a time.
Any help will be appreciated.

Use POJO classes (Setter or Getter) to manage this type of condition. Use boolean variable in that class and change its values according to the position true or false.
POJO Class Like :
public class CheckListSource {
public boolean isSelected;
public boolean isSelected() {
return isSelected;
}
public void setSelected(boolean selected) {
isSelected = selected;
}
}
In your adapter :
private ArrayList<CheckListSource > itemsData;
public ChildListAdapter(Activity activity, ArrayList<ChildListResponse> baseResponse) {
this.itemsData = baseResponse;
this.activity = activity;
}
In BindViewHolder Like :
viewHolder.checkParentView.setTag(itemsData.get(position));
viewHolder.checkParentView.setOnClickListener(checkedListener);
private View.OnClickListener checkedListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
CheckListSource childListResponse = (CheckListSource ) v.getTag();
if (childListResponse.isSelected())
childListResponse.setSelected(false);
else
childListResponse.setSelected(true);
notifyDataSetChanged();
}
};

Use a boolean array in your Activity. Each boolean value corresponds to a RadioButton.
If a RadioButton is checked, set its boolean value to true, and set all other boolean values in the array to false.
In the getView() of your Adapter, call your_radio_button.setChecked(your_boolean_array[position]).
Once the boolean array is modified, call your_adapter.notifyDataSetChanged().

Checkout this it works for me..
public class ProgramAdapter extends ArrayAdapter<KeyInformation> {
private final String TAG = "ProgramAdapter";
private List<KeyInformation> mList;
private Context mContext;
private LayoutInflater mInflater;
private int mSelectedPosition = -1;
private RadioButton mSelectedRB;
private String mUserApllication = "";
public ProgramAdapter(Context context, List<KeyInformation> objects) {
super(context, R.layout.program_item, objects);
mContext = context;
mList = objects;
mInflater = ( LayoutInflater ) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mUserApllication = Settings.System.getString(mContext.getContentResolver(),
Settings.System.PROGRAMMABLE_KEY_ACTION);
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {

if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.program_item, parent, false);
holder.mImageView = (ImageView) convertView.findViewById(R.id.icon);
holder.mTextView = (TextView) convertView.findViewById(R.id.text);
holder.mSeparator = (TextView) convertView.findViewById(R.id.title_separator);
holder.mRadioButton = (RadioButton) convertView.findViewById(R.id.radioBtn);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.mRadioButton.setOnClickListener( new View.OnClickListener() {
#Override
public void onClick(View view) {
if(position != mSelectedPosition && mSelectedRB != null){
mSelectedRB.setChecked(false);
}
mUserApllication ="";
mSelectedPosition = position;
mSelectedRB = (RadioButton) view;
}
});
String userApp = mList.get(position).packageName;
if(mUserApllication.equals(userApp)) {
mSelectedPosition = position;
}
if (mSelectedPosition != position) {
holder.mRadioButton.setChecked(false);
} else {
holder.mRadioButton.setChecked(true);
mSelectedRB = holder.mRadioButton;
}
holder.mImageView.setImageDrawable(mList.get(position).icon);
holder.mTextView.setText(mList.get(position).lable);
if (position == 5) {
holder.mSeparator.setVisibility(View.VISIBLE);
} else {
holder.mSeparator.setVisibility(View.GONE);
}
return convertView;
}
public int getmSelectedPosition () {
return mSelectedPosition;
}
private static class ViewHolder {
