Android password hint font problem

If you working with password EditText and you enable input password by

edtPassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);

you will face font problem in some device (list at the end of my answer)

For example,

If I use android:inputType="textPassword", this problem don't happened

To fix this problem, there are some ways

  1. Use setTransformationMethod instead inputType

=> Font will working well however the keyboard display not very well (it only display text, don't display number on top of text)

  1. Use Typeface.DEFAULT

=> Keyboard display well, font may working not well. Example sans-serif-light is a default font for all View in my application => after setTypeface(Typeface.DEFAULT), the EditText font still look different

  1. Use android:fontFamily="sans-serif"
    For some device, it will CRASH, check my answer here And also font still look different


cache the typeface before setInputType then reuse it

Typeface cache = edtPassword.getTypeface();
edtPassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
