[Update the style]

<style name="TextAppearance.App.TextInputLayout" parent="@android:style/TextAppearance">

</style>

Answer 1

Use setError(CharSequence error, Drawable icon) method. Set the drawable as null:

editText.setError("Pls provide email", null);

Answer 2

TextInputLayout is now part of the new material package. Here is an update on how I got a password field with validation working:

Layout:

<com.google.android.material.textfield.TextInputLayout
    android:id="@+id/loginPasswordInputLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="@dimen/grid"
    android:hint="@string/onboarding_hint_password"
    app:errorEnabled="true"
    app:passwordToggleContentDescription="@string/onboarding_toggle_description_password"
    app:passwordToggleEnabled="true"
    app:passwordToggleTint="?colorAccent">

    <com.google.android.material.textfield.TextInputEditText
        android:id="@+id/loginPasswordInputText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="start|center"
        android:inputType="textPassword"
        android:lines="1"
        tools:text="@string/onboarding_hint_password" />
</com.google.android.material.textfield.TextInputLayout>

Setting the error message and hiding the icon in code can then be achieved with the following:

loginPasswordInputLayout.error = errorMessage
// Error icon overlaps with password visibility toggle, so remove it:
loginPasswordInputLayout.setErrorIconDrawable(0)

This way you get the red (or colour of your choice) text and underline, but the password visibility toggle icon stays fully accessible.
