android自己定义状态栏!!1

1.首先去掉原先系统自带的actionBar,在api 11 后才出现actionBar的概念,在v11的value的style.xml的文件里改动,假设没有的话默认的value就是v11

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
        <item name="android:actionBarStyle">@style/myActvionBar</item>
    </style>

    <style name="myActvionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
        <!-- 去掉actionBar的左边图标 -->
        <item name="android:displayOptions">@null</item>
    </style>

2.在layout目录中写出actionBar的布局文件

3.在Java代码中载入布局

 /**
  * 设置ActionBar
  * @param context
  * @param layoutId
  */
 public static void setActonBarLayout(Context context,int layoutId) {
  ActionBar actionBar = ((Activity)context).getActionBar();
  if (actionBar != null) {
   actionBar.setDisplayShowHomeEnabled(false);
   actionBar.setDisplayShowCustomEnabled(true);
   LayoutInflater layoutInflater = (LayoutInflater) context
     .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
   View v = layoutInflater.inflate(layoutId, null);
   ActionBar.LayoutParams layoutParams = new ActionBar.LayoutParams(
     LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
   v.setLayoutParams(layoutParams);
   actionBar.setCustomView(v);
  }
 }

终于的效果:
