如何在Android中显示TextInputLayout中的上标提示？我好像搞不懂，这是我的代码

<com.google.android.material.textfield.TextInputLayout
    android:id="@+id/textInputLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="Enter your name">

    <com.google.android.material.textfield.TextInputEditText
        android:id="@+id/editText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</com.google.android.material.textfield.TextInputLayout>

TextInputLayout textInputLayout = findViewById(R.id.textInputLayout);
textInputLayout.setError("Invalid name");

textInputLayout.setErrorEnabled(true);

textInputLayout.setErrorTextColor(ColorStateList.valueOf(Color.RED));

textInputLayout.setErrorTextAppearance(R.style.CustomErrorText);

<style name="CustomErrorText" parent="TextAppearance.Design.Error">
    <item name="android:textSize">12sp</item>
</style>
