How to switch between hide and view password

It is really easy to achieve since the Support Library v24.2.0.

What you need to do is just:

1. Add the design library to your dependencies

    dependencies {
         compile "com.android.support:design:24.2.0"
    }
   

2. Use TextInputEditText in conjunction with TextInputLayout

    <android.support.design.widget.TextInputLayout
        android:id="@+id/etPasswordLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:passwordToggleEnabled="true"
        android:layout_marginBottom="@dimen/login_spacing_bottom">
   
        <android.support.design.widget.TextInputEditText
            android:id="@+id/etPassword"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/fragment_login_password_hint"
            android:inputType="textPassword"/>
    </android.support.design.widget.TextInputLayout>
   

The passwordToggleEnabled attribute will do the job!

3. In your root layout don’t forget to add xmlns:app="http://schemas.android.com/apk/res-auto"

4. You can customize your password toggle by using:

app:passwordToggleDrawable – Drawable to use as the password input visibility toggle icon.
app:passwordToggleTint – Icon to use for the password input visibility toggle.
app:passwordToggleTintMode – Blending mode used to apply the background tint.
