Partially visible Action Mode Icons android

Question

I have just update android support library from com.android.support:appcompat-v7:25.3.1 to com.android.support:appcompat-v7:26.0.1. It changed the appearance of action mode icons. Now they are half-visible/pressed as shown in the picture.

Is it a bug in the support library or I am doing something wrong?

Here is how I set the icons of action mode.

  @Override
            public boolean onCreateActionMode(android.view.ActionMode mode, Menu menu) {

                menu.add("Delete").setIcon(R.drawable.ic_action_discard);
                menu.add("Copy").setIcon(R.drawable.ic_action_copy);
                return true;
            }

Update

I have verified this is a bug in android support library.

here is the link https://issuetracker.google.com/issues/64207386

Update

Google updated the new release. From Recent Support Library Revisions page.

Bug fixes

Menu icons are flattened on Support Library 26.0.0

Answer 1

Chances are there that it's becuase of less height than the icons require.

You can try this.

1. Add these two lines in values -> styles.xml -> Apptheme (style name must be only AppTheme).

   <item name="android:actionButtonStyle">@style/actionButtonSize</item>
   <item name="actionButtonStyle">@style/actionButtonSize</item>
   

2. And copy this style (in same styles.xml).

   <style name="actionButtonSize" parent="Widget.AppCompat.ActionButton">
       <item name="android:minWidth">30dp</item>
       <item name="android:maxWidth">48dp</item>
       <item name="android:width">38dp</item>
       <item name="android:minHeight">30dp</item>
       <item name="android:maxHeight">48dp</item>
       <item name="android:height">38dp</item>
   </style>
   

Also, sizes given here can be small or large as I've not tested them so set/adjust them according to your requirement.
And yes, if this doesn't work, please let me know, I'll provide more help.
