### ChangeLog

### Usage

1. Add the dependencies to your build.gradle file, StatusBarUtil is avaiable in JCenter:

   ```groovy
   compile 'com.jaeger.statusbarutil:library:1.5.1'
   ```

   I fixed typo, change "statusbaruitl" to "statusbarutil", please notice this.

2. Call method you need after `setContentView()`,  such as :

   ```java
   setContentView(R.layout.main_activity);
   ...
   StatusBarUtil.setColor(MainActivity.this, mColor);
   ```

3. If you use this util in a page which containing a `DrawerLayout`, you need add `android:fitsSystemWindows="true"` for `DrawerLayout` in your layout XML:

   ```xml
   <android.support.v4.widget.DrawerLayout
       xmlns:android="http://schemas.android.com/apk/res/android"
       xmlns:app="http://schemas.android.com/apk/res-auto"
       android:id="@+id/drawer_layout"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:fitsSystemWindows="true">

       ...

   </android.support.v4.widget.DrawerLayout>
   ```

4. Set color for swipe back page

   Recommend using  with [bingoogolapple/BGASwipeBackLayout\-Android: Android Activity 滑动返回](https://github.com/bingoogolapple/BGASwipeBackLayout-Android)

   ```java
   StatusBarUtil.setColorForSwipeBack(Activity activity, @ColorInt int color, int statusBarAlpha)
   ```

5. All `statusBarAlpha` value you set should between 0 ~ 255

6. How to use in Fragment, please read [UseInFragmentActivity.java](https://github.com/laobie/StatusBarUtil/blob/master/sample/src/main/java/com/jaeger/statusbarutil/UseInFragmentActivity.java) 

   Handle all Fragments in ViewPager as ImageViewFragment, add a fake View in your Fragment layout as StatusBar :

   ```xml
   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:orientation="vertical">

       <View
           android:id="@+id/fake_statusbar_view"
           android:layout_width="match_parent"
           android:layout_height="@dimen/statusbar_view_height"
           android:background="@color/colorPrimary"/>

       <TextView
           android:id="@+id/tv_title"
           android:layout_width="match_parent"
           android:layout_height="56dp"
           android:background="@color/colorPrimary"
           android:gravity="center"
           android:text="@string/app_name"
           android:textColor="@color/white"
           android:textSize="24sp"/>   
   </LinearLayout>
   ```

   The fake StatusBar View height value ` statusbar_view_height`  defined in `dimens.xml`

   ```xml
   ~ values-v19/dimens.xml

   <dimen name="statusbar_view_height">25dp</dimen>

   ~ values/dimens.xml

   <dimen name="statusbar_view_height">0dp</dimen>
   ```

   When you change StatusBarColor :

   ```java
   mFakeStatusBar.setBackgroundColor(color);
   ```

   Then in the Activity which contains ViewPage, just invoke

   ```java
   StatusBarUtil.setTranslucentForImageViewInFragment(UseInFragmentActivity.this, null);
   ```

   Please read [UseInFragmentActivity.java](https://github.com/laobie/StatusBarUtil/blob/master/sample/src/main/java/com/jaeger/statusbarutil/UseInFragmentActivity.java)
