str.setTypeface(notoKyfiBold);
str.setText("دوس هنا للكتابه");
str.setTextColor(Color.BLACK);
str.setGravity(Gravity.CENTER);
str.setFocusable(false);
str.setFocusableInTouchMode(false);
str.setCursorVisible(false);
str.setClickable(false);
str.setMaxLines(15);
str.setEnabled(false);
str.setActivated(false);
str.setSingleLine(false);
str.setMaxTextSize(50);
str.setKeyListener(null);
str.setMinTextSize(0);
str.setHintTextColor(Color.TRANSPARENT);
str.setBackground(null);
str.setBackgroundColor(Color.TRANSPARENT);
str.setSizeToFit(true);
str.setPadding(10,0,10,0);
str.endBatchEdit();
str.setDrawingCacheBackgroundColor(Color.TRANSPARENT);
str.getPaint().setStrokeWidth(4);
str.setHighlightColor(Color.TRANSPARENT);
str.getPaint().setStyle(Paint.Style.STROKE);

the line is the one directly below the text, not that bottom border:

If you want to do it programmatically, then you can use the following code.

//assume an EditText object with name myEditText
myEditText.setInputType(myEditText.getInputType() | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS does not seem to work as expected on all keyboards whereas InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD has the drawback that it also disables toggling the language in the keyboard and the swipe gesture to add the text.
