安卓之手机状态栏的设置和背景色的改变

qq实现了沉浸状态栏的效果，如下图： 

如图，好多应用如金山词霸等也实现了这样的效果。这样的效果很酷炫，其实设置很简单。 
不过要说明的是，这种效果只能在API19以及以上版本中才能够做到。 
如果想让界面Activity中实现这种效果，代码如下：

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">if(VERSION<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.SDK</span>_INT >= VERSION_CODES<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.KITKAT</span>) {            //透明状态栏            getWindow()<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.addFlags</span>(WindowManager<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.LayoutParams</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.FLAG</span>_TRANSLUCENT_STATUS)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span>            //透明导航栏            getWindow()<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.addFlags</span>(WindowManager<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.LayoutParams</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.FLAG</span>_TRANSLUCENT_NAVIGATION)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span>        }</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul>

VERSION_CODES.KITKAT就是API19的名称，只有手机系统版本大于19，才执行判断中的代码，才能显示沉浸状态栏的效果。 
同时，这几句代码要写在setContentView(R.layout.XX);方法之前执行。

以上代码复制到Activity中执行效果如图： 

这个界面的布局如下：

<code class="hljs xml has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px;

由于根节点中LinearLayout设置了背景颜色6699CC，所以上面的状态栏中设置成了6699CC这个颜色。

大家会问，上面有个标题栏，怎么去掉？很简单，使用requestWindowFeature(Window.FEATURE_NO_TITLE);就可以了，也是在setContentView(R.layout.XX);方法之前执行。 
效果图： 

这样是不是达到了整个界面同意的颜色的效果了。

上面的设置方法只是让一个Activity设置成沉浸状态栏的效果，如果想让整个应用中都想沉浸状态栏的效果，如何设置呢？有！！！确实有方法！！ 
 
如图所示，在res目录下面新建一个values-v19文件夹，下面新建一个styles.xml文件，内容如下：

<code class="hljs xml has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-tag" style="color: rgb(0, 102, 102); box-sizing: border-box;"><<span class="hljs-title" style="box-sizing: border-box; color: rgb(0, 0, 136);">resources</span>></span>    <span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;"><!--        Base application theme for API 19+.    --></span>    <span class="hljs-tag" style="color: rgb(0, 102, 102); box-sizing: border-box;"><<span class="hljs-title" style="box-sizing: border-box; color: rgb(0, 0, 136);">style</span> <span class="hljs-attribute" style="box-sizing: border-box; color: rgb(102, 0, 102);">name</span>=<span class="hljs-value" style="box-sizing: border-box; color: rgb(0, 136, 0);">"AppBaseTheme"</span> <span class="hljs-attribute" style="box-sizing: border-box; color: rgb(102, 0, 102);">parent</span>=<span class="hljs-value" style="box-sizing: border-box; color: rgb(0, 136, 0);">"android:Theme.Holo.Light.DarkActionBar"</span>></span><span class="css" style="box-sizing: border-box;">        <!<span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">--</span> <span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">API</span> 14 <span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">theme</span> <span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">customizations</span> <span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">can</span> <span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">go</span> <span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">here</span>. <span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">--</span>>        <<span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">item</span> <span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">name</span>="<span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">android</span><span class="hljs-pseudo" style="color: rgb(0, 0, 0); box-sizing: border-box;">:windowTranslucentStatus"</span>><span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">true</span></<span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">item</span>>        <<span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">item</span> <span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">name</span>="<span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">android</span><span class="hljs-pseudo" style="color: rgb(0, 0, 0); box-sizing: border-box;">:windowTranslucentNavigation"</span>><span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">true</span></<span class="hljs-tag" style="color: rgb(0, 0, 0); box-sizing: border-box;">item</span>>    </span><span class="hljs-tag" style="color: rgb(0, 102, 102); box-sizing: border-box;"></<span class="hljs-title" style="box-sizing: border-box; color: rgb(0, 0, 136);">style</span>></span><span class="hljs-tag" style="color: rgb(0, 102, 102); box-sizing: border-box;"></<span class="hljs-title" style="box-sizing: border-box; color: rgb(0, 0, 136);">resources</span>></span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li><li style="box-sizing: border-box; padding: 0px 5px;">10</li></ul>

这样安卓系统会根据这个目录中的配置，自动进行设置，自动会加载这个目录下边的设置。 
这样设置之后，代码中的判断语句就不需要了。运行之后，你会发现整个应用的界面都会是沉浸状态栏的形式了。

可能细心的人，可能发现了，经过上面的设置，状态栏中的字体和应用中的顶部挨得太近了。如图： 

上面图中箭头部分，靠的太近了，这个该怎么设置呢？

在该activity的布局文件中根元素下设置： 
android:clipToPadding=”true” 
android:fitsSystemWindows=”true” 
就可以了。 
效果图： 
 

设置之后，间距是不是达到了我们想要的距离了，是正常的距离。 
但是新问题出现了，状态栏颜色成了系统默认的颜色背景了。如何设置呢？简单！！！只要把上面的 
android:clipToPadding=”true” 
android:fitsSystemWindows=”true” 
这两句代码放在布局文件的根元素的第一个元素下面就可以了。例如我的上面的界面的根元素是RelativeLayout，他的第一个元素是标题栏，一个返回按钮 ，一个图片按钮，可以把上面的两句代码放在标题栏的布局中，例如：

<code class="hljs handlebars has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre;

最后要注意：状态栏透明可能导致布局向上便宜，所以需要设置根布局的android:fitsSystemWindows=”true”

上面可以设置状态栏和标题栏的字体颜色和背景颜色，方法有多种。状态栏字体颜色好像V6有两种，一个白色，一种黑色，不设置黑色的话，默认就是白色。不懂得可以留言，或者加我的扣扣1808012171.
