Add an extra attribute to that EditText
programmatically and you are done:
password.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
For numeric password (pin):
password.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD);
Also, make sure that the cursor is at the end of the text in the EditText
because when you change the input type the cursor will be automatically set to the starting point. So I suggest using the following code:
et_password.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
et_password.setSelection(et_password.getText().length());
When using Data Binding, you can make use of the following code:
<data>
<import type="android.text.InputType"/>
.
.
.
<EditText
android:inputType="@{someViewModel.isMasked ?
(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD) :
InputType.TYPE_CLASS_TEXT }"
If using Kotlin:
password.inputType = InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_VARIATION_PASSWORD
