前言
我们知道IOS上的应用,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,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:
实现这个效果有两个方法: 1.在xml中设置主题或自定义style;
theme.Holo.light.NoActionbar.TranslucentDecortheme.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; 这个情况下可创建一个BaseActivity,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.top_bg_color);//通知栏所需颜色 } setContentVIEw(R.layout.main_activity); } @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。

代码复制进你的项目即可,好了,这些工作完成之后我们来看下效果:
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:
这样就达到了咱们最开始的样式。
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); }
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! 状态栏高度算法:
/** * 状态栏高度算法 * @param activity * @return */ public static int getStatusHeight(Activity activity){ int statusHeight = 0; Rect localRect = new Rect(); activity.getwindow().getDecorVIEw().getwindowVisibledisplayFrame(localRect); statusHeight = localRect.top; if (0 == statusHeight){ Class<?> localClass; try { localClass = Class.forname("com.androID.internal.R$dimen"); Object localObject = localClass.newInstance(); int i5 = Integer.parseInt(localClass.getFIEld("status_bar_height").get(localObject).toString()); statusHeight = activity.getResources().getDimensionPixelSize(i5); } catch (ClassNotFoundException e) { e.printstacktrace(); } catch (illegalaccessexception e) { e.printstacktrace(); } catch (InstantiationException e) { e.printstacktrace(); } catch (NumberFormatException e) { e.printstacktrace(); } catch (IllegalArgumentException e) { e.printstacktrace(); } catch (SecurityException e) { e.printstacktrace(); } catch (NoSuchFIEldException e) { e.printstacktrace(); } } return statusHeight; }
