Android自定义状态栏颜色与应用标题栏颜色一致

每次看ios上的应用，应用中状态栏的颜色总能与应用标题栏颜色保持一致，用户体验很不错，对于这种效果，像我这种好奇心强的人就会去看看那安卓是否可以呢？若是在安卓4.4之前，答案是否定的，但在4.4之后，谷歌允许开发者自定义状态栏背景颜色啦，这是个不错的体验！若你手机上安装有最新版的qq，并且你的安卓sdk版本是4.4及以上，你可以看下它的效果：

实现此功能有两种方法：

1.在xml中设置主题或自定义style；

theme.holo.light.noactionbar.translucentdecor

theme.holo.noactionbar.translucentdecor

<style name="apptheme" parent="appbasetheme">
<!-- status bar -->
<item name="android:windowtranslucentstatus">true</item>
<!-- navigation bar -->
<item name="android:windowtranslucentnavigation">true</item>
</style>

鉴于市面上各种手机的sdk的各种版本，不建议采用这种方法；

2.在代码中控制；

首先创建一个activity，在oncreate方法中进行处理：

@override 
protected void oncreate(bundle savedinstancestate) { 
super.oncreate(savedinstancestate); 
if (build.version.sdk_int >= build.version_codes.kitkat) { 
settranslucentstatus(true); 
systembartintmanager tintmanager = new systembartintmanager(this); 
tintmanager.setstatusbartintenabled(true); 
tintmanager.setstatusbartintresource(r.color.barcolor);//通知栏所需颜色 
} 
setcontentview(r.layout.activity_main); 
} 
@targetapi(19) 
private void settranslucentstatus(boolean on) { 
window win = getwindow(); 
windowmanager.layoutparams winparams = win.getattributes(); 
final int bits = windowmanager.layoutparams.flag_translucent_status; 
if (on) { 
winparams.flags |= bits; 
} else { 
winparams.flags &= ~bits; 
} 
win.setattributes(winparams); 
}

需注意的是， tintmanager.setstatusbartintresource(r.color.top_bg_color);这一步的颜色值（即把你的状态栏颜色与你的标题栏颜色保持一致）要写在color.xml中去，如果用color.prasecolor则会报错。

接下来我们看看效果图（前一个图是没有设置颜色的效果图，后一个是设置颜色的效果图）：

貌似已经达到效果了，但仔细观察，好像标题栏被提上去了，就是说app界面全屏了，状态了盖在了app上，恩，这并非我们想要的效果，那如何将界面从状态栏下部开始呢，只需要在activity的布局文件最外层控件加上一个属性：

android:fitssystemwindows="true"就可以啦！看下效果：

大功告成！

ps：在使用过程中发现了一些问题，使用以上方法对单个activity有效，但是对继承了tabactivity的导航页怎么办呢？假如mainactivity继承了tabactivity，tab1activity、tab2activity、tab3activity是三个子项，那么设置状态栏的代码需写在mainactivity中，而 android:fitssystemwindows="true"需写在三个子activity的xml布局文件中，这样设置后仍然有问题，就是进入应用后首页也就是tab1activity没有问题，而tab2activity、tab3activity却没达到效果，它们的效果相当于未加android:fitssystemwindows="true"时的效果，期初我怀疑是activity不同的原因，因此我把tab1activity和tab3activity调了下位置，结果tab3activity成为首页后正常，而tab1activity又不正常了，百思不得姐，最后实在没办法，就在tab2activity、tab3activity的oncreate方法中加了几句代码：

if (build.version.sdk_int >= build.version_codes.kitkat) {
((linearlayout)findviewbyid(r.id.ll)).setpadding(0, 
sysutils.getstatusheight(this), 0,0);
}

意思是，先求出状态栏高度，然后设置最外层控件的paddingtop值为状态栏高度，结果正好达到效果，至于为什么只有首页activity可以达到效果，而后面的子项无法达到效果，本人也在郁闷中，有知道的朋友可以分享下！

伴随着android5.0的发布也更新了support-v7-appcompat 到v21，其中增加了toolbar，recyclerview，cardview等控件。
android5.0对改变app样式下了不小的功夫，写法也和以前不一样了，这里也简单介绍一下

这样是不是清晰很多了，继续加油吧，编程的路还很长，我们慢慢走
