android image button tooltip
Solution 1
With api level 26 you can use the built-in TooltipText: Via XML:
android:toolTipText="yourText"
If your minSdk is below 26, use ToolTipCompat, for example:
TooltipCompat.setTooltipText(yourView, "your String");
Unfortunately, there's is no way to do this in your XML-File.
Solution 2
This is the code that Support Library v7 uses to show "cheat sheet"s for action menu items:
public boolean onLongClick(View v) {
if (hasText()) {
// Don't show the cheat sheet for items that already show text.
return false;
}
final int[] screenPos = new int[2];
final Rect displayFrame = new Rect();
getLocationOnScreen(screenPos);
getWindowVisibleDisplayFrame(displayFrame);
final Context context = getContext();
final int width = getWidth();
final int height = getHeight();
final int midy = screenPos[1] + height / 2;
int referenceX = screenPos[0] + width / 2;
if (ViewCompat.getLayoutDirection(v) == ViewCompat.LAYOUT_DIRECTION_LTR) {
final int screenWidth = context.getResources().getDisplayMetrics().widthPixels;
referenceX = screenWidth - referenceX; // mirror
}
Toast cheatSheet = Toast.makeText(context, mItemData.getTitle(), Toast.LENGTH_SHORT);
if (midy < displayFrame.height()) {
// Show along the top; follow action buttons
cheatSheet.setGravity(Gravity.TOP | GravityCompat.END, referenceX, height);
} else {
// Show along the bottom center
cheatSheet.setGravity(Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0, height);
}
cheatSheet.show();
return true;
}

Solution that works in xml and supports minSdk less than 26
@BindingAdapter("tooltipTextCompat")
fun bindTooltipText(view: View, tooltipText: String) {
TooltipCompat.setTooltipText(view, tooltipText)
}
and usage in layout.xml
app:tooltipTextCompat="@{@string/add_for_all_tooltip}"

Not exactly what you are looking for but it does something very similar.
1) Insure your view is android:longClickable="true"
(should be by default) and has a defined content description android:contentDescription="@string/myText"
:
<ImageButton android:id="@+id/button_edit"
android:contentDescription="@string/myText"
android:src="@drawable/ic_action_edit"
android:onClick="onEdit"
android:longClickable="true"/>
2) Register a callback to be invoked when the view is long pressed. Handler will display the content description as a toast message.
findViewById(R.id.button_edit).setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View view) {
Toast.makeText(context,view.getContentDescription(), Toast.LENGTH_SHORT).show();
return true;
}
});

I'm trying to build an app with image buttons that work like the action bar but i can't get them to show a tooltip on long press.
<ImageButton android:id="@+id/editUrgent" style="?android:attr/borderlessButtonStyle" android:layout_width="48dp" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_toLeftOf="@+id/editImportant" android:hint="@string/hint_urgent" android:contentDescription="@string/hint_urgent" android:text="@string/hint_urgent" android:src="@drawable/clock_light" />
android:contentDescription works for hovering(s-pen) but long press still does nothing.

ban-geoengineering over 9 yearsThis isn't ideal as it won't show the tooltip where the long-click was made, but will show it in the standard Toast message location(??).

Slion almost 4 yearsandroidx understands app:tooltipText="@string/mystring" but at runtime it just won't work. Do I need both XML and code?
-
krishnakumarp almost 4 yearsYes. both are required.
-
Slion almost 4 yearsSo that kotlin function scope is global? It is then being picked up by the binding framework thanks to that @BindingAdapter annotation? I may as well just bind "contentDescription" and save myself more work and redundancy in the XML right?
-
Slion almost 4 yearsGot it working eventually was missing that base layout element in my XML and the call to the generated MyLayoutBinding.inflate function. See youtu.be/W7uujFrljW0
