文章标签 应用 支持 沉浸

本文主要是介绍如何让自己的应用支持沉浸栏，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

安卓4.4以后，Google推出了沉浸栏效果的，如图所示：

这样的效果可谓是美如画啊，我非常期待应用都能有这样的效果，

这样我们的安卓的画面效果就有了大幅度的提高。 

然后令我失望的大多数的应用一直迟迟没有支持这种效果，这很令我

费解。除了系统自带的个别应用外，只有QQ空间和UC浏览器支持了

这种效果。越看越觉得好看，于是我决定在自己开发的项目中也能支

持这种效果。经过一天努力，总算做好了，现在分享自己的经验。


其实很简单，我们只需要主动暴露自己的ActionBar的配色或者背景图

给系统就好了。当然还有其他情况，和这个就非常类似了，我们就以

这种情况为例子。

在github上找到了一个开源的项目，叫ImmerseStatusBar

添加的方法如下：

首先封装一个manager类

然后在你的activity中封装一个打开沉浸效果的方法

    protected 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);}

在create方法中判断版本是否支持 支持就开启 并且进行设置

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {setTranslucentStatus(true);params.topMargin = 30;titleBarLayout.setLayoutParams(params);mTintManager = new SystemBarTintManager(this);mTintManager.setStatusBarTintEnabled(true);mTintManager.setStatusBarTintResource(R.drawable.title_bg);//加载你的actionbar的颜色或者背景图}


这样就可以了 大家有什么问题可以留言，有什么不妥的欢迎指出 希望大家多多支持一下，谢谢。
