}

For release notes see releases.

Integration

There is no setup needed because Tooltip Hints are embedded into the android.widget.TextView class.

Start using android:tooltipText attribute in your layouts, or if using it already you can skip this section. See more about Tooltips Designs, Tooltips and TooltipsCompat.

 <AutoCompleteTextView
    android:tooltipText="@string/tooltip_email"
    android:id="@+id/email"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textEmailAddress"
    />

To reveal a tooltip hint call View's showTooltipHint() method:

AutoCompleteTextView view = findViewById(R.id.email);
view.showTooltipHint()

Or just as well you might want to do it for the whole layout:

LinearLayout layout = findViewById(R.id.parent);
layout.showTooltipHint()

Customization

When customizing Tooltip Hint style, you need to override the "TooltipHint" (case sensitive) style definition. Also, if you inherit style from "parent = _TooltipHint" that will ensure all defaults are set.

Supported customization items:

• android:drawable - tooltip hint icon
• anchor - position of the icon
• android:drawablePadding - padding around the icon

A custom style would look like this:

<style name="TooltipHint" parent="_TooltipHint">
    <item name="android:drawable">@drawable/ic_tooltip_hint</item>
    <item name="tooltipAnchor">right</item>
    <item name="android:drawablePadding">4dp</item>
</style>
