[Tabs] Useless tooltip on tab with text

Description: Tooltip is shown even when the tab has text, and tooltip has identical text. Probably caused by https://github.com/material-components/material-components-android/commit/fd3639092e1ffef9dc11bcedf79f32801d85e898, although there is “if tab is icon only” in description, but I don’t see how it could make it “icon only”. 🤷‍♂️

Expected behavior: Tooltip is not shown on tabs which have text, if there’s no contentDescription specified.

Source code:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <com.google.android.material.tabs.TabLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <com.google.android.material.tabs.TabItem
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Tab 1" />

        <com.google.android.material.tabs.TabItem
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Tab 2" />

    </com.google.android.material.tabs.TabLayout>

</LinearLayout>

Looking through the guidelines there is a section about not showing tooltips when they simply restate visible UI text - https://material.io/components/tooltips#placement

I’ll talk bring this up with the team.

Confirmed with the team. So the behavior is working as intended because tabs has limited displaying space. When users enlarge the text scale, we cannot enlarge tabs’ text scale. Instead tooltips can provide larger text for the accessibility purpose. Closing the issue…
