How to change the background color of Action Bar&#

问题:

I\'d like to change the background color of the option (overflow) menu in Android 4.2. I have tried all the methods but it is still showing the default color set by the theme. I used the following code & XML configs.

MainActivity.java

public class MainActivity extends Activity {

@SuppressLint(\"NewApi\")
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    getActionBar().setIcon(R.drawable.ic_launcher);     
    getActionBar().setTitle(\"Sample Menu\");
    getActionBar().setBackgroundDrawable(new 
               ColorDrawable(Color.parseColor(\"#33B5E5\"))); 

    int titleId = Resources.getSystem().getIdentifier(\"action_bar_title\", \"id\", \"android\");
    TextView titleText = (TextView)findViewById(titleId);
    titleText.setTextColor(Color.parseColor(\"#ffffff\"));

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    setMenuBackground();
    return true;
}

protected void setMenuBackground(){                     
    // Log.d(TAG, \"Enterting setMenuBackGround\");  
    getLayoutInflater().setFactory( new Factory() { 

        @Override
        public View onCreateView(String name, Context context,
                AttributeSet attrs) {
            if ( name.equalsIgnoreCase( \"com.android.internal.view.menu.IconMenuItemView\" ) ) {
                try { // Ask our inflater to create the view  
                    LayoutInflater f = getLayoutInflater();  
                    final View view = f.createView( name, null, attrs );  
                    /* The background gets refreshed each time a new item is added the options menu.  
                    * So each time Android applies the default background we need to set our own  
                    * background. This is done using a thread giving the background change as runnable 
                    * object */
                    new Handler().post( new Runnable() {  
                        public void run () {  
                            // sets the background color   
                            view.setBackgroundResource( R.color.menubg);
                            // sets the text color              
                            ((TextView) view).setTextColor(Color.WHITE);
                            // sets the text size              
                            ((TextView) view).setTextSize(18);
            }
                    } );  
                return view;
            }
        catch ( InflateException e ) {}
        catch ( ClassNotFoundException e ) {}  
    } 
            return null;
        }});
}

}

Menu.xml

<menu xmlns:android=\"http://schemas.android.com/apk/res/android\" >

<item
    android:id=\"@+id/action_settings\"
    android:icon=\"@drawable/menu\"
    android:showAsAction=\"always\"
    android:title=\"@string/action_settings\">
    <menu>
        <item
            android:id=\"@+id/item1\"             
            android:showAsAction=\"always\"
            android:title=\"@string/item1\" />
        <item
            android:id=\"@+id/item2\"             
            android:showAsAction=\"always\"
            android:title=\"@string/item2\" />
        <item
            android:id=\"@+id/item3\"
            android:showAsAction=\"always\"
            android:title=\"@string/item3\" />
        <item
            android:id=\"@+id/item4\"
            android:showAsAction=\"always\"
            android:title=\"@string/item4\" />
    </menu>
</item>

</menu>

color.xml

<color name=\"menubg\">#33B5E5</color>

The above setMenuBackground is not taking any effect:

In the above picture, I want to change the menu background from black to the blue color in the Action Bar. How can I achieve this, and what I did do wrong?

回答1:

There is an easy way to change the colors in Actionbar Use ActionBar Generator and copy paste all file in your res folder and change your theme in Android.manifest file.

回答2:

The Action Bar Style Generator, suggested by Sunny, is very useful, but it generates a lot of files, most of which are irrelevant if you only want to change the background colour.

So, I dug deeper into the zip it generates, and tried to narrow down what are the parts that matter, so I can make the minimum amount of changes to my app. Below is what I found out.

---

In the style generator, the relevant setting is Popup color, which affects \"Overflow menu, submenu and spinner panel background\".

Go on and generate the zip, but out of all the files generated, you only really need one image, menu_dropdown_panel_example.9.png, which looks something like this:

So, add the different resolution versions of it to res/drawable-*. (And perhaps rename them to menu_dropdown_panel.9.png.)

Then, as an example, in res/values/themes.xml you would have the following, with android:popupMenuStyle and android:popupBackground being the key settings.

<resources>

    <style name=\"MyAppActionBarTheme\" parent=\"android:Theme.Holo.Light\">
        <item name=\"android:popupMenuStyle\">@style/MyApp.PopupMenu</item>
        <item name=\"android:actionBarStyle\">@style/MyApp.ActionBar</item>
    </style>

    <!-- The beef: background color for Action Bar overflow menu -->
    <style name=\"MyApp.PopupMenu\" parent=\"android:Widget.Holo.Light.ListPopupWindow\">
        <item name=\"android:popupBackground\">@drawable/menu_dropdown_panel</item>
    </style>

    <!-- Bonus: if you want to style whole Action Bar, not just the menu -->
    <style name=\"MyApp.ActionBar\" parent=\"android:Widget.Holo.Light.ActionBar.Solid\">
        <!-- Blue background color & black bottom border -->
        <item name=\"android:background\">@drawable/blue_action_bar_background</item>
    </style>   

</resources>

And, of course, in AndroidManifest.xml:

<application
    android:theme=\"@style/MyAppActionBarTheme\" 
    ... >

What you get with this setup:

Note that I\'m using Theme.Holo.Light as the base theme. If you use Theme.Holo (Holo Dark), there\'s an additional step needed as this answer describes!

Also, if you (like me) wanted to style the whole Action Bar, not just the menu, put something like this in res/drawable/blue_action_bar_background.xml:

<!-- Bonus: if you want to style whole Action Bar, not just the menu -->
<layer-list xmlns:android=\"http://schemas.android.com/apk/res/android\" >

    <item>
        <shape android:shape=\"rectangle\">
            <stroke android:width=\"2dp\" android:color=\"#FF000000\" />
            <solid android:color=\"#FF2070B0\" />                   
        </shape>
    </item>

    <item android:bottom=\"2dp\">
        <shape android:shape=\"rectangle\">
            <stroke android:width=\"2dp\" android:color=\"#FF2070B0\" />
            <solid android:color=\"#00000000\" />
            <padding android:bottom=\"2dp\" />
        </shape>
    </item>

</layer-list>

Works great at least on Android 4.0+ (API level 14+).

In case people are still visiting for a working solution, here is what worked for me:-- This is for Appcompat support library. This is in continuation to ActionBar styling explained here

Following is the styles.xml file.

<resources>
    <!-- Base application theme. -->
    <style name=\"AppTheme\" parent=\"Theme.AppCompat.Light\">
        <!-- This is the styling for action bar -->
        <item name=\"actionBarStyle\">@style/MyActionBar</item>
        <!--To change the text styling of options menu items</item>-->
        <item name=\"android:itemTextAppearance\">@style/MyActionBar.MenuTextStyle</item>
        <!--To change the background of options menu-->
        <item name=\"android:itemBackground\">@color/skyBlue</item>
    </style>

    <style name=\"MyActionBar\" parent=\"@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse\">
        <item name=\"background\">@color/red</item>
        <item name=\"titleTextStyle\">@style/MyActionBarTitle</item>
    </style>

    <style name=\"MyActionBarTitle\" parent=\"@style/TextAppearance.AppCompat.Widget.ActionBar.Title\">
        <item name=\"android:textColor\">@color/white</item>
    </style>

    <style name=\"MyActionBar.MenuTextStyle\"
        parent=\"style/TextAppearance.AppCompat.Widget.ActionBar.Title\">
        <item name=\"android:textColor\">@color/red</item>
        <item name=\"android:textStyle\">bold</item>
        <item name=\"android:textSize\">25sp</item>
    </style>
</resources>

and this is how it looks--MenuItem background color is skyblue and MenuItem text color is pink with textsize as 25sp:--

If you read this, it\'s probably because all the previous answers didn\'t work for your Holo Dark based theme.

Holo Dark uses an additional wrapper for the PopupMenus, so after doing what Jonik suggested you have to add the following style to your \'xml\' file:

<style name=\"PopupWrapper\" parent=\"@android:style/Theme.Holo\">
    <item name=\"android:popupMenuStyle\">@style/YourPopupMenu</item>
</style>

Then reference it in your theme block:

<style name=\"Your.cool.Theme\" parent=\"@android:style/Theme.Holo\">
    .
    .
    .
    <item name=\"android:actionBarWidgetTheme\">@style/PopupWrapper</item>
</style>

That\'s it!

My simple trick to change background color and color of the text in Popup Menu / Option Menu

<style name=\"CustomActionBarTheme\"
       parent=\"@android:style/Theme.Holo\">
    <item name=\"android:popupMenuStyle\">@style/MyPopupMenu</item>
    <item name=\"android:itemTextAppearance\">@style/TextAppearance</item>
</style>
<!-- Popup Menu Background Color styles -->
<style name=\"MyPopupMenu\" 
       parent=\"@android:style/Widget.Holo.ListPopupWindow\">
    <item name=\"android:popupBackground\">@color/Your_color_for_background</item> 
</style>
<!-- Popup Menu Text Color styles -->
<style name=\"TextAppearance\">
    <item name=\"android:textColor\">@color/Your_color_for_text</item>
</style>

You can apply styles and Themes in Overflow MenuItem as per below. OverFlow Menu is ListView so, we can apply theme as per listview.

Apply below code in styles.xml

<style name=\"AppTheme\" parent=\"@android:style/Theme.Holo.Light\">
<item name=\"android:dropDownListViewStyle\">@style/PopupMenuListView</item>
        <item name=\"android:actionBarWidgetTheme\">@style/PopupMenuTextView</item>
        <item name=\"android:popupMenuStyle\">@style/PopupMenu</item>
        <item name=\"android:listPreferredItemHeightSmall\">40dp</item>
</style>

<!-- Change Overflow Menu ListView Divider Property -->
    <style name=\"PopupMenuListView\" parent=\"@android:style/Widget.Holo.ListView.DropDown\">
        <item name=\"android:divider\">@color/app_navigation_divider</item>
        <item name=\"android:dividerHeight\">1sp</item>
        <item name=\"android:listSelector\">@drawable/list_selector</item>
    </style>

    <!-- Change Overflow Menu ListView Text Size and Text Size -->
    <style name=\"PopupMenuTextView\" parent=\"@android:style/Widget.Holo.Light.TextView\">
        <item name=\"android:textColor\">@color/app_white</item>
        <item name=\"android:textStyle\">normal</item>
        <item name=\"android:textSize\">18sp</item>
        <item name=\"android:drawablePadding\">25dp</item>
        <item name=\"android:drawableRight\">@drawable/navigation_arrow_selector</item>
    </style>

    <!-- Change Overflow Menu Background -->
    <style name=\"PopupMenu\" parent=\"android:Widget.Holo.Light.ListPopupWindow\">
        <item name=\"android:popupBackground\">@drawable/menu_overflow_bg</item>
    </style>

In case you are working in the latest toolbar in android studio then here is the smallest solution To change the toolbar options menu color, add this to your toolbar element

 app:popupTheme=\"@style/MyDarkToolbarStyle\"

Then in your styles.xml define the popup menu style

<style name=\"MyDarkToolbarStyle\" parent=\"ThemeOverlay.AppCompat.Light\"> <item name=\"android:colorBackground\">@color/mtrl_white_100</item> <item name=\"android:textColor\">@color/mtrl_light_blue_900</item> </style>

Note that you need to use colorBackground not background. The latter would be applied to everything (the menu itself and each menu item), the former applies only to the popup menu.

I\'m also struck with this same problem, finally i got simple solution. just added one line to action bar style.

<style name=\"AppTheme.AppBarOverlay\" parent=\"ThemeOverlay.AppCompat.Dark.ActionBar\">
    <item name=\"android:textColorPrimary\">@color/colorAccent</item>
    <item name=\"android:colorBackground\">@color/colorAppWhite</item>
</style>

\"android:colorBackground\" is enough to change option menu background

回答9:

I was able to change colour of action overflow by just putting hex value at:

    <!-- The beef: background color for Action Bar overflow menu -->
<style name=\"MyApp.PopupMenu\" parent=\"android:Widget.Holo.Light.ListPopupWindow\">
    <item name=\"android:popupBackground\">HEX VALUE OF COLOR</item>
</style>

回答10:

FAST way!

styles.xml

<style name=\"popupTheme\" parent=\"Theme.AppCompat.Light\">

    <item name=\"android:background\">@color/colorBackground</item>
    <item name=\"android:textColor\">@color/colorItem</item>

</style>

Then add this specific styles to your AppTheme styles

<style name=\"AppTheme\" parent=\"Theme.AppCompat.Light.NoActionBar\">
    ...
    <item name=\"popupTheme\">@style/popupTheme</item>
</style>

DONE!

Try this code. Add this snippet to your res>values>styles.xml

<style name=\"AppTheme\" parent=\"AppBaseTheme\">
    <item name=\"android:actionBarWidgetTheme\">@style/Theme.stylingactionbar.widget</item>
</style>
<style name=\"PopupMenu\" parent=\"@android:style/Widget.Holo.ListPopupWindow\">
    <item name=\"android:popupBackground\">@color/DarkSlateBlue</item>
 <!-- for @color you have to create a color.xml in res > values -->
</style>
<style name=\"Theme.stylingactionbar.widget\" parent=\"@android:style/Theme.Holo\">
    <item name=\"android:popupMenuStyle\">@style/PopupMenu</item>
</style>

And in Manifest.xml add below snippet under application

 <application
    android:allowBackup=\"true\"
    android:icon=\"@drawable/ic_launcher\"
    android:label=\"@string/app_name\"

     android:theme=\"@style/AppTheme\"  >

回答12:

Add following to your Styles.xml

<style name=\"Custom_Theme\" parent=\"Theme.AppCompat.Light.DarkActionBar\">

    <item name=\"android:itemBackground\">@color/white</item>
    <item name=\"android:textColor\">@color/colorPrimaryDark</item>

</style>

Change theme in activity_main.xml only.

android:theme=\"@style/Custom_Theme\"

回答13:

Following are the changes required in your theme for changing action bar & overflow menu background color. You need to configure \"android:background\" of actionBarStyle & popupMenuStyle

<application
            android:name=\"....\"
            android:theme=\"@style/AppLightTheme\">

<style name=\"AppLightTheme\" parent=\"android:Theme.Holo.Light\">      
        <item name=\"android:actionBarStyle\">@style/ActionBarLight</item>
        <item name=\"android:popupMenuStyle\">@style/ListPopupWindowLight</item>
</style>

<style name=\"ActionBarLight\" parent=\"android:style/Widget.Holo.Light.ActionBar\">
        <item name=\"android:background\">@color/white</item>
</style>


<style name=\"ListPopupWindowLight\"parent=\"@android:style/Widget.Holo.Light.ListPopupWindow\">
        <item name=\"android:background\">@color/white</item>
</style>

回答14:

<style name=\"customTheme\" parent=\"any_parent_theme\">
    <item name=\"android:itemBackground\">#424242</item>
    <item name=\"android:itemTextAppearance\">@style/TextAppearance</item>
</style>

<style name=\"TextAppearance\">
    <item name=\"android:textColor\">#E9E2BF</item>
</style>

回答15:

Within your app theme you can set the android:itemBackground property to change the color of the action menu.

For example:

<style name=\"AppThemeDark\" parent=\"Theme.AppCompat.Light.DarkActionBar\">
        <item name=\"colorPrimary\">@color/drk_colorPrimary</item>
        <item name=\"colorPrimaryDark\">@color/drk_colorPrimaryDark</item>
        <item name=\"colorAccent\">@color/drk_colorAccent</item>
        <item name=\"actionBarStyle\">@style/NoTitle</item>
        <item name=\"windowNoTitle\">true</item>
        <item name=\"android:textColor\">@color/white</item>

        <!-- THIS IS WHERE YOU CHANGE THE COLOR -->
        <item name=\"android:itemBackground\">@color/drk_colorPrimary</item>
</style>
