    // Add a digit view for each digit

    inputValue.setBackgroundColor(getResources().getColor(android.R.color.transparent));
    inputValue.setTextColor(getResources().getColor(android.R.color.transparent));
    inputValue.setCursorVisible(false);


    inputValue.setFilters(new InputFilter[]{new InputFilter.LengthFilter(mDigits)});
    inputValue.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD);

    inputValue.setImeOptions(EditorInfo.IME_FLAG_NO_EXTRACT_UI);
    inputValue.setOnFocusChangeListener(new OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            // Update the selected state of the views
            int length = inputValue.getText().length();
            for (int i = 0; i < mDigits; i++) {
                childView.getChildAt(i).setSelected(hasFocus && (mAccentType == ACCENT_ALL ||
                        (mAccentType == ACCENT_CHARACTER && (i == length ||
                                (i == mDigits - 1 && length == mDigits)))));
            }

            if (mOnFocusChangeListener != null) {
                mOnFocusChangeListener.onFocusChange(CustomPinConfirmView.this, hasFocus);
            }
        }
    });

    for (int i = 0; i < mDigits; i++) {
        DigitView digitView = new DigitView(getContext());
        digitView.setLayoutParams(new LinearLayout.LayoutParams(valueInPixels, valueInPixels));
        wapContainer = new LinearLayout(mContext);
        wapContainer.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, 5f / mDigits));
        wapContainer.setGravity(Gravity.CENTER);
        digitView.setTextColor(Color.WHITE);
        digitView.setTextSize(pxFromDp(14, mContext));

        digitView.setGravity(Gravity.CENTER);
        mWidgets.add(digitView);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            digitView.setElevation(mDigitElevation);
        }
        wapContainer.addView(digitView);
        childView.addView(wapContainer);
    }




    inputValue.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void afterTextChanged(Editable s) {

            int length = s.length();
            for (int i = 0; i < mDigits; i++) {
                if (s.length() > i) {
                    String mask = mMask == null || mMask.length() == 0 ?
                            String.valueOf(s.charAt(i)) : mMask;

                    if(childView.getChildAt(i) instanceof  LinearLayout)
                    {
                        Log.e("Taggggggggggg",childView.getChildCount() +"");
                        Log.e("Taggggggggggg",childView.getClass().getSimpleName() + " " + childView.getClass().getSimpleName().length());
                        //((TextView) childView.getChildAt(i)).setText(mask);
                    }
                }
                else {

                }

            }

        }
    });
}

As you can See i can Log my wapContainer witch i created programmatically but i can't(i don't know) how to get wapContainer 's childView(my textviews) if anyone knows solution please help me thanks everyone

Usual way to do this is to set an ID to your textView.

Then use findViewById() to get the reference to it.

Hope this helps.
