Disable tooltipText in BottomNavigationView

Question

Im using

implementation 'com.google.android.material:material:1.1.0-alpha09'

this is my menu

 <item
    android:id="@+id/llHome"
    android:icon="@drawable/selector_menu_home"
    android:title="@string/navigation.bottom.home"
    app:tooltipText="@null" />

but as much as I write long click or disable it, the tooltip with the name of the menu continues to appear. Any idea how to disable the tooltip?

Answer 1

It will either show the tooltip text or the tab title. You might be able to clear out the text by iterating over all the BottomNavigationItemViews and calling TooltipCompat.setTooltipText(view, null)

This works! I call the following code inside my Fragment.onViewCreated() bottomNavigationView.menu.forEach { TooltipCompat.setTooltipText(activity!!.findViewById(it.itemId), null) } – Facia

Is there a XML solution? – Maitland

@DIRTYDAVE you can add a binding adapter using data-binding – Pressroom

Answer 2

This not works for me, bottomNavigationView.menu.forEach { TooltipCompat.setTooltipText(activity!!.findViewById(it.itemId), null) }is not working so below answer worked for me

bottomNavigationView.menu.forEach {
                val view = bottomNavigationView.findViewById<View>(it.itemId)
                view.setOnLongClickListener {
                    true
                }
            }

Actually

bottomNavigationView.menu.forEach {
    TooltipCompat.setTooltipText(activity!!.findViewById(it.itemId), null) 
}

is not working after pressing the bottom button.

Here is my solution:

fun BottomNavigationView.disableTooltipText() {
  try {
    val menuViewField = this.javaClass.getDeclaredField("menuView")
    menuViewField.isAccessible = true
    val menuView = menuViewField.get(this) as BottomNavigationMenuView
    menuView.forEach {
      it.setOnLongClickListener {
        true
      }
    }
  } catch (e: Exception) {
    Log.w(e)
  }
}

I don't like the idea of using reflection to do these things, but setting the long click listener part works for me. – Pressroom

We could create an extension with this answser: https://mcmap.net/q/1262488/-disable-tooltiptext-in-bottomnavigationview

fun BottomNavigationView.disableTooltipText() {
    val menuIterator = menu.iterator()
    while(menuIterator.hasNext()) {
        val menu = menuIterator.next()
        findViewById<View>(menu.itemId)?.let { view ->
            TooltipCompat.setTooltipText(view, null)
        }
    }
}

Answer 5

Nothing was working for me until I combined the above answers and did this:

for (int i = 0; i < bottomNavigationView.getMenu().size(); i++) {
        bottomNavigationView.findViewById(bottomNavigationView.getMenu().getItem(i).getItemId()).setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View view) {
                return true;
            }
        });

    }
