Q:

Can't get string value from custom dialog in my fragment

I have my fragment where user can send points to another user now I need to create custom dialog where user need to reenter his pin. I done it following few tutorials but value is always null;
    public void onViewCreated(View view, Bundle savedInstanceState) {
    LayoutInflater inflater = LayoutInflater.from(getContext());
    View confirmation=inflater.inflate(R.layout.confirmation,null);
    pin  = (EditText) confirmation.findViewById(R.id.PinChecker);

    }

    SendPointsButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            AlertDialog.Builder builder = new AlertDialog.Builder(getContext());

            builder.setView(R.layout.confirmation);

            builder.setPositiveButton("DA", new    DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    pinCheck= String.valueOf(pin.getText().toString());
                    Log.d("Pin",pinCheck);
} 

I want to assing value from pin(EditText) to string called pinCheck;

A:

I think you should pass the inflated layout (confirmation) to builder.setView() as below:
  final View confirmation=inflater.inflate(R.layout.confirmation,null);
  pin  = (EditText) confirmation.findViewById(R.id.PinChecker);

....

SendPointsButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        AlertDialog.Builder builder = new AlertDialog.Builder(getContext());

        builder.setView(confirmation);

        builder.setPositiveButton("DA", new    DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                pinCheck= String.valueOf(pin.getText().toString());
                Log.d("Pin",pinCheck);
} 

Hope this will help.
