Adding * and # key to the soft keyboard

1) PROBLEM:
I have an EditText in which the user has to enter USSD code.
Problem is, for entering USSD code the user has to switch to symbol keyboard (two to three times) which creates a very bad user experience.
USSD Code Examples: *345*77#, *333*25#, *123*678# etc.
<EditText
android:id="#+id/field_code"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:imeActionId="#integer/imo_action_search"
android:imeOptions="actionSearch"
android:inputType="phone" />
2) What I need:
How can I replace the highlighted buttons (below image) with * and # buttons without using a custom keyboard?
3) What I have tried!!!
1) All InputTypes for EditText.
2) Google the issue, the only solution I have found is a custom keyboard but I want to know is there any simple solution.

Each keyboard app has its own layout and you can't change it. For example android:inputType="phone" has different layouts on Gboard and SwiftKey.
Solution:
You should implement a custom InAppKeyboard and show it to the user instead of the system keyboard."Creating an In-App Keyboard for your Android Apps" is a good tutorial that describes how to develop a custom InAppKeyboard like this but you can design your desired layout and use it in your app easily.
Update:
For Using InAppKeyboard with dialog, I have an idea. I developed a custom DialogFragment which has 2 parts: 1. The dialog content part2. The custom keyboard part named CustomKeyboardDialog.
You can extend this class and create your custom dialog. Both setContentView and findViewById methods are available and you can use them to manage your dialog UI. You must override onCreate method in your custom dialog implementation and call setContentView there. Then override onCreateView method, call findViewById there and find your EditText and attach it custom keyboard by calling attachToCustomKeyboard method.
CustomKeyboardDialog.java
public abstract class CustomKeyboardDialog extends DialogFragment {
private View mRootView;
private int mContentLayoutResID;
private View mContentView;
private CustomKeyboardView mCustomKeyboardView;
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {

Dialog dialog = getDialog();
if (dialog != null) {
dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
}
}

Two checkbox in recyclerview changing state when scrolling

Edit
Solved issue by removing two lines
holder.checkbox.setChecked(mListenerList.get(position).isSelected());
holder.checkbox.setChecked(mListenerList.get(position).isSelected2());
And By Adding
#Override
public long getItemId(int position) {
return position;
}
#Override
public int getItemViewType(int position) {
return position;
}
I am not editing my original code for future developers.
Main Question before Edit Start from Here
I am working on fantasy cricket app where I am selecting the captain and vice captain from a list of 11 player.
I am using a checkbox for selecting the captain and vice captain.
The selection of checkbox is working fine with my code, but the issue is when I select 1st player as a captain(C) and 2nd player as Vice-Captain(VC) and then scroll the list the checkbox state is changing and showing other player selected.
So is there any right way to do that thing?
I have tried many way they are working when there is single checkbox but in my case there is two and only one can be select from the list.
Please refer to the attached screenshots on the bottom for clarity.

Selecting C and VC
After scrolling top to bottom and bottom to top
Please ignore Radio group. My code is working fine with checkbox, it's only creating issues when scrolling.

For checkbox you need to use checkbox.OnCheckedChangeListener() instead of checkbox.setOnClickListener()
Follow this steps
add a new Boolean variable in your BeanDBTeam class
public class BeanDBTeam
{
boolean isChecked;
public boolean getisChecked() {
return isChecked;
}
public void setIsChecked(boolean flag) {
isChecked= flag;
}
}
Now inside you onBindViewHolder() add below code
#Override
public void onBindViewHolder(#NonNull ViewHolder viewHolder, int position) {
BeanDBTeam bean = mListenerList.get(position).getisChecked()
// check here the flag and status of checkbox based on flag
holder.checkbox2.setChecked(bean.getisChecked());
holder.checkbox2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
// set flag of checkbox status in your list when user check or uncheck the checkbox
bean.setIsChecked(isChecked);

}
});
}

This is what recycling behaviour is, You can use other answer that are also correct but as you are having limited entries in your list you can actually disable recycling your recyclerview. Use below code in your adapter:
#Override
public void onBindViewHolder(final CommentViewHolder viewHolder, final int position) {
viewHolder.setIsRecyclable(false);
}

As #Nilesh suggested you , to use the Bean class for checkbox state remember functionality like below:
/**
* CheckType ==>>1 For the first checkbox
* CheckType ==>>2 For the second checkbox
* CheckType ==>>0 For the None
*/
public class BeanDBTeam
{
int checkType;
public int getCheckType() {
return checkType;
}
public void setCheckType(int checkType) {
this.checkType = checkType;
}
}
Inside the MyViewHolder you need to apply the setOnCheckedChangeListener listener and get position from the getAdapterPosition() like below
public class MyViewHolder extends RecyclerView.ViewHolder {
TextView tv_PlayerName, tv_SelectCaptain, tv_SelectViceCaptain, tv_PlayerTeamName, tv_PlayerPoints, tv_TeamNumber;
ImageView im_PlayerImage, im_onetwox;
CheckBox checkbox, checkbox2;
RadioGroup radiogroup;
RadioButton radio, radio2;
public MyViewHolder(View view) {
super(view);
tv_PlayerName = view.findViewById(R.id.tv_PlayerName);
tv_PlayerTeamName = view.findViewById(R.id.tv_PlayerTeamName);
tv_PlayerPoints = view.findViewById(R.id.tv_PlayerPoints);
im_PlayerImage = view.findViewById(R.id.im_PlayerImage);
im_onetwox = view.findViewById(R.id.im_onetwox);
tv_TeamNumber = view.findViewById(R.id.tv_TeamNumber);
tv_SelectViceCaptain = view.findViewById(R.id.tv_SelectViceCaptain);
tv_SelectCaptain = view.findViewById(R.id.tv_SelectCaptain);
checkbox = view.findViewById(R.id.checkbox);
checkbox2 = view.findViewById(R.id.checkbox2);
radiogroup = view.findViewById(R.id.radiogroup);
radio = view.findViewById(R.id.radio);
radio2 = view.findViewById(R.id.radio2);
/**
* NOW WE APPLY THE setOnCheckedChangeListener functionality for the checkboxlistener
*/
checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// set flag of checkbox status in your list when user check or uncheck the checkbox
if (checkbox) {
YOUR_ARRAYLIST.get(getAdapterPosition()).setCheckType(1);
}
else {
YOUR_ARRAYLIST.get(getAdapterPosition()).setCheckType(0);
}
notifyDataChanged();
}
});
checkbox2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// set flag of checkbox status in your list when user check or uncheck the checkbox
if (checkbox) {
YOUR_ARRAYLIST.get(getAdapterPosition()).setCheckType(2);
}
else {
YOUR_ARRAYLIST.get(getAdapterPosition()).setCheckType(0);
}
notifyDataChanged();
}
});
}
}
And inside the onBindViewHolder we need to set the Checkbox according to the selection like below
#Override
public void onBindViewHolder(#NonNull ViewHolder viewHolder, int position) {
BeanDBTeam bean = mListenerList.get(position).getisChecked()
// check here the flag and status of checkbox based on flag
if(bean.getCheckType()==0) {
holder.checkbox.setChecked(false);
holder.checkbox2.setChecked(false);
}
else if(bean.getCheckType()==1) {
holder.checkbox.setChecked(true);
holder.checkbox2.setChecked(false);
}
else if(bean.getCheckType()==2) {
holder.checkbox.setChecked(false);
holder.checkbox2.setChecked(true);
}
}

RadioButton state and Button validation

I am facing two issues.
Radio buttons in radiogroup loosing state: when I click yes or no and scroll down the list view it looses the radiobutton value which is checked. I tried many ways to fix it but unable to achieve.
Submit button validation(Please refer image four): list of questions user should select either yes or no before clicking on submit button, if user click on submit button without selecting either yes or no it should them a toast message. all the questions should be selected with either yes or no. More specific each radiogroup should give me yes or no, not empty string.
Thanks in advance.

Try this.
Use ViewHolder so it does not lose the data set
Custom Adapter class
#Override
public View getView(final int i, View view, ViewGroup viewGroup) {
ViewHolder viewHolder;
if(view == null){
view = inflter.inflate(R.layout.list_items, null);
viewHolder = new ViewHolder();
ViewHoldwe.question = (TextView) view.findViewById(R.id.question);
viewHolder.yes = (RadioButton) view.findViewById(R.id.yes);
viewHolder.no = (RadioButton) view.findViewById(R.id.no);
viewHolder.rg = (RadioGroup) view.findViewById(R.id.radio_group);
view.setTag(viewHolder)
}else{
viewHolder = (ViewHolder) view.getTag();
viewHolder.rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (viewHolder.yes.isChecked()) {
viewHolder.yes.setBackgroundColor(Color.GREEN);
viewHolder.no.setBackgroundColor(Color.BLACK);
}
if (viewHolder.no.isChecked()){
viewHolder.no.setBackgroundColor(Color.rgb(255,165,0));
viewHolder.yes.setBackgroundColor(Color.BLACK);
}
}
});
viewHolder.yes.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked)
selectedAnswers.set(i, "1");
}
});
viewHolder.no.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked)
selectedAnswers.set(i, "2");
}
});
question.setText(questionsList[i]);
}
return view;
}
Make a private inner class
private class ViewHolder{
RadioButton yes;
TextView question;
RadioButton no ;
RadioGroup rg;
}

RadioGroup listener dont work

I have a Fragment that displays a Dialog.
Inside that Dialog there is a RadioGroup.
I tried to create a listener to this RadioGroup, but i didn't successed.
Fragment --> Dialog --> RadioGroup
I tried four ways:
OnCheckedChangeListener on RadioGroup.
OnClickListener on RadioGroup.
OnCheckedChangeListener on RadioButton.
OnClickListener on RadioButton
No one worked.
Here is my code:

How to get value of all selected radio buttons from all the views in sliding Fragment

I have three views in sliding Fragment with Survey Questions having dynamic radiobuttons (the layout for all views are same, i am just repeating). I can get the data of selected radiobuttons from one screen, but how can i get the data of all selected radiobuttons from all screens ? Below is my working code
