Question

I have a textbox in my application and as the picture below shows,

by clicking on show-checkbox the pin edittext type must be changed to password
and any existing character in the box must be transformed to *.

I know we can use xml to define password edittext but as I explained, I need to changed the edittext type programmatically.

I couldn’t find any keyword for textbox to change its type to password, any advice.

Answer 1

Store the text of EditText in some temporary variable using

String temporary_stored_text = mEditText.getText().toString.trim();

and then on selection of the Show checkbox change the input type of EditText from Normal to password type using

mEditText.setTransformationMethod(PasswordTransformationMethod.getInstance());

and refill the EditText with the temporary stored value of EditText using

mEditText.setText(temporary_stored_text);

To get it back to normal do nothing,

mEditText.setTransformationMode(null);

and get the Text.
