Change Status Bar color when entering Contextual Action Mode

Question

I have an application that uses theme attribute (colorPrimaryDark) to color the Status Bar on Android v21+:

Answer 1

    private int statusBarColor;

    @Override
    public boolean onCreateActionMode(ActionMode mode, Menu menu) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            //hold current color of status bar
            statusBarColor = getWindow().getStatusBarColor();
            //set your gray color
            getWindow().setStatusBarColor(0xFF555555);
        }
        ...
    }

    ...

    @Override
    public void onDestroyActionMode(ActionMode mode) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            //return to "old" color of status bar
            getWindow().setStatusBarColor(statusBarColor); 
        }
        ...
    }
});

Answer 2

Place it on your Application theme(both style.xml and v21 style.xml) or create custom theme for where you want to change.

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light">
        <item name="colorPrimary">@color/color_primary</item>
        <item name="colorPrimaryDark">@color/color_secondary</item>
        <item name="colorAccent">@color/color_accent</item>
        **<item name="android:statusBarColor">@color/**YOUR_COLOR**</item>**
    </style>
</resources>
