TranslucentStatusBar	SetStatusBarColor

This is a utils for status bar, And you do not need to change your style.xml file. The most feature is you can toggle setStatusBarColor and translucentStatusBar without recreate activity.

	//set color for status bar
	StatusBarCompat.setStatusBarColor(Activity activity, int color)
	//add alpha to color
	StatusBarCompat.setStatusBarColor(Activity activity, int statusColor, int alpha)
	
	//translucent status bar
	StatusBarCompat.translucentStatusBar(activity);
	//should hide status bar background (default black background) when SDK >= 21
	StatusBarCompat.translucentStatusBar(Activity activity, boolean hideStatusBarBackground);

	//set color for CollapsingToolbarLayout
	setStatusBarColorForCollapsingToolbar(Activity activity, AppBarLayout appBarLayout, CollapsingToolbarLayout collapsingToolbarLayout,
                                                                         Toolbar toolbar, int statusColor)

How to use

Use it after call setContentView
If use FullScreen Activity, must call StatusBarCompat.translucentStatusBar(activity);

About Demo:

Demo shows One Activity with four Fragments.

CommonFragment call setStatusBarColor method, SeekBar can change statusBar's alpha.
TranslucentFragment call translucentStatusBar method, when sdk >= 21, button can toggle hide/show statusBar's shadow.
DrawerFragment call setStatusBarColor method, show how to compat for DrawerLayout and CoordinatorLayout.
CollapsingFragment call setStatusBarColorForCollapsingToolbar method, compat for CollapsingToolbarLayout.

Issues:

These problem only show in SDK between 19 and 21:

If work with TabActivity, It will show a black line in contentView, so you can call StatusBarCompat.setStatusBarColor(Activity activity, int statusColor, int alpha) and the suggest alpha is 112.
If first view is DrawerLayout, let its child view set fitsSystemWindow to false.

透明状态栏只有在 SDK >= 19 (Android 4.4) 才会生效.

透明状态栏	设置状态栏的颜色
	)

这是一个为了兼容处理状态栏的工具类,可以不需要设置不同的style.xml文件,最重要的特性就是可以在**不重启 Activity 的情况下切换 setStatusBarColor 和 translucentStatusBar **. 提供以下 API :

	    //设置状态栏的颜色
    	StatusBarCompat.setStatusBarColor(Activity activity, int color)
    	//添加alpha值
    	StatusBarCompat.setStatusBarColor(Activity activity, int statusColor, int alpha)

        //透明状态栏
    	StatusBarCompat.translucentStatusBar(activity);
    	//SDK >= 21时, 取消状态栏的阴影
    	StatusBarCompat.translucentStatusBar(Activity activity, boolean hideStatusBarBackground);

    	//为 CollapsingToolbarLayout 设置颜色
    	setStatusBarColorForCollapsingToolbar(Activity activity, AppBarLayout appBarLayout, CollapsingToolbarLayout collapsingToolbarLayout,
                                                                     Toolbar toolbar, int statusColor)

怎么使用

在 setContentView 方法调用后再设置.
如果使用了全屏 Activity ,记得调用StatusBarCompat.translucentStatusBar(activity);

Demo 说明:

Demo 只有一个 Activity , 分四个 Tab.

CommonFragment 为正常布局, 可以通过 SeekBar 来调整状态栏颜色的 alpha 值. 调用方法为: setStatusBarColor.
TranslucentFragment 为图片布局, 展示透明状态栏效果, SDK >= 21时, 可以通过按钮显示\隐藏 statusBar 的 shadow, 调用方法为: translucentStatusBar.
DrawerFragment 展示 DrawerLayout + CoordinatorLayout, 调用方法为: setStatusBarColor.
CollapsingFragment 展示 CollapsingLayout 的适配效果, 调用方法为: setStatusBarColorForCollapsingToolbar.

已知问题

这些问题仅仅出现在 4.4 上

如果用在 TabActivity 上, 会有一条黑线在状态栏下面, 推荐使用 StatusBarCompat.setStatusBarColor(Activity activity, int statusColor, int alpha) 方法, 推荐的透明值为 112.
如果 layout 中第一个 View 为 DrawerLayout, 那么它的子 View 的 fitsSystemWindow 需要设置为 false.
