Show the password with EditText

Question

I use an EditText to enter password. And a CheckBox to show password or not. Below function is the part:

public void ShowPassword() {
    if (cb.isChecked()) {
          


        

Answer 1

okay:

To show readeable text:

setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD)

To "star" the password:

setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD)

But why? The Type_Text_Variation_Password set it to stars, but why does only adding Type_Claas_Text revive the visibel password?
I would have thought that Type_Text_Variation_VISIBLE_Password comes into play ...
