android - Change the style of ActionBar -

-

im working on actionbar , i'm trying change style, want background white , text color blue, im doing following style.xml:

<resources>  <!-- base application theme. --> <style name="apptheme" parent="theme.appcompat.light">     <!-- customize theme here. -->     <item name="colorprimary">@color/action_bar</item>     <item name="coloraccent">@color/top_bar</item>     <item name="colorprimarydark">@color/cyan_500</item>     <item name="android:windowcontentoverlay">@null</item>     <item name="android:actionbarstyle">@style/myactionbar</item> </style>  <style name="myactionbar"                   parent="@style/widget.appcompat.light.actionbar">     <item name="android:actionbarsize">20dp</item>     <item name="android:background">@color/white</item>     <item name="android:titletextstyle">@style/mytitletextbarstyle</item> </style>  <style name="mytitletextbarstyle" parent="@style/textappearance.appcompat.widget.actionbar.title">     <item name="android:textcolor">@color/colorrb</item> </style>  </resources>

and nothing happening, api 15 22. have managed change background code doing this:

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_reasonlocation);     android.support.v7.app.actionbar mab = getsupportactionbar();     mab.settitle(getstring(r.string.reasonandlocation));     mcd.setcolor(getresources().getcolor(r.color.white));     mab.setbackgrounddrawable(mcd);     ... }

if know how can solve this, either style.xml or code, appreciate.

you can define color of actionbar (and other stuff) by creating custom style:

simply edit the res/values/styles.xmlfile of android project.

for example this:

        <resources>  <style name="mycustomtheme"      parent="@android:style/theme.holo.light">      <item name="android:actionbarstyle">@style/myactionbartheme</item>  </style>  <style name="myactionbartheme" parent="@android:style/widget.holo.light.actionbar">  <item name="android:background">any_hex_color_code</item> </style>  </resources>

then set "mycustomtheme" theme of activity contains actionbar.

you can set color actionbar this:

  actionbar actionbar = getactionbar();  actionbar.setbackgrounddrawable(new colordrawable(color.red)); // set desired color
