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

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：
|
1
2
3
4

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
colorAccent,colorPrimary,colorPrimaryDark的作用：
现在新建一个项目基本都会在 style.xml 设置基础的 AppTheme，但是系统的给提供的设置属性又比较多。
所以在此收集记录，以便之后查找方便。
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:colorPrimaryDark">@color/material_animations_primary_darkitem>
<item name="android:statusBarColor">@color/material_animations_primary_darkitem>
<item name="android:colorPrimary">@color/material_animations_primaryitem>
<item name="android:windowBackground">@color/light_greyitem>
<item name="android:navigationBarColor">@color/navigationColoritem>
<item name="android:textColorPrimary">@android:color/blackitem>
<item name="android:textColorPrimaryInverse">@color/text_lightitem>
<item name="android:colorForeground">@color/colorForegrounditem>
<item name="android:colorBackground">@color/colorForegrounditem>
<item name="android:colorControlNormal">@color/colorControlNormalitem>
