TextInputLayout passwordToggle with rounded corners

Question

I'm using TextInputLayout from android design library version 25.1.1. With the following code:

<android.support.design.widget.TextInputLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:local="http://schemas.android.com/apk/res-auto"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  local:passwordToggleEnabled="true"
  local:hintEnabled="false">
  <android.support.design.widget.TextInputEditText
    android:id="@+id/confirmationEditText"
    android:singleLine="true" />
</android.support.design.widget.TextInputLayout>

But when password toggle icon is pressed, its ripple effect is drawn above the background of TextInput:

How can I set rounded corners radius for passwordToggle? Can I reference its existing background and "wrap" it with needed properties (how to find Path for default drawable that is used by toggle)?

Answer 1

Just use the Material Components library and the standard TextInputLayout component.

Add the app:boxCornerRadiusBottomEnd="xxdp", app:boxCornerRadiusTopEnd="xxdp", app:boxCornerRadiusBottomStart="xxdp", app:boxCornerRadiusTopStart="xxdp" attributes.

Something like:

    <com.google.android.material.textfield.TextInputLayout
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
        app:endIconMode="password_toggle"
        app:boxCornerRadiusBottomEnd="8dp"
        app:boxCornerRadiusTopEnd="8dp"
        app:boxCornerRadiusBottomStart="8dp"
        app:boxCornerRadiusTopStart="8dp"
        ...>

Otherwise you can define a custom style and use the shapeAppearanceOverlay attribute:

    <com.google.android.material.textfield.TextInputLayout
        android:id="@+id/custom_end_icon"
        android:hint="Hint text"
        style="@style/OutlinedRoundedBox"
        ...>

with:

  <style name="OutlinedRoundedBox" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox">
    <item name="shapeAppearanceOverlay">@style/ShapeAppearanceOverlay.MyApp.TextInputLayout.Rounded</item>
  </style>

  <style name="ShapeAppearanceOverlay.MyApp.TextInputLayout.Rounded" parent="">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">8dp</item>
  </style>
