另外一种设置沉浸式标题栏的方式

今天又看到了另外一种设置沉浸式标题栏的方式,比上次写的那个使用主题,设置主题背景色的要好很多了。尤其是设置主题背景色后,程序从后台到前台ui界面没加载出来会显示出短暂的标题栏的颜色,因此设置主题背景颜色的方式还是有些缺陷。
废话不多说,我介绍的这个方法使用了小米的一个类:SystemBarTintManager

经过测试在其他的手机上一样适用,只是那个设置标题栏字体颜色为黑色不能用而已。
使用起来也很简单,在你的activity或者baseactivity的oncreate方法中加入以下代码:
setTranslucentStatus方法
然后需要在你的布局文件最外层添加以下代码
android:fitsSystemWindows="true"
android:clipToPadding="false" 这个在设置主题的那里是设置为true的,注意区分
如果你只用了普通的activity,那么一切事情都已经结束了。但我做的司信项目,在主界面上用的是一个activitygroup,然后用tabhost添加了4个activity,这样的话会有一些出入,需要在activitygroup的方法上写上以上代码,activity继承了baseactivity,因此也加入了这些属性,会造成自定义的导航栏文字显示不全。
这个时候就再调用一下

使用起来也很简单,在你的activity或者baseactivity的oncreate方法中加入以下代码:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { setTranslucentStatus(true); } mTintManager = new SystemBarTintManager(this); mTintManager.setStatusBarTintEnabled(true); //使StatusBarTintView 和 actionbar的颜色保持一致,风格统一。 mTintManager.setStatusBarTintResource(R.color.navbar); // 设置状态栏的文字颜色 mTintManager.setStatusBarDarkMode(false, this);
setTranslucentStatus方法
@TargetApi(19) 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); }
然后需要在你的布局文件最外层添加以下代码
android:fitsSystemWindows="true"
android:clipToPadding="false" 这个在设置主题的那里是设置为true的,注意区分
如果你只用了普通的activity,那么一切事情都已经结束了。但我做的司信项目,在主界面上用的是一个activitygroup,然后用tabhost添加了4个activity,这样的话会有一些出入,需要在activitygroup的方法上写上以上代码,activity继承了baseactivity,因此也加入了这些属性,会造成自定义的导航栏文字显示不全。
这个时候就再调用一下
mTintManager.setStatusBarTintEnabled(false);//把自定义的titlebar设置不显示 这样就可以了,效果是与之前的一样的,因此不再贴图。好处就是不会忽然闪一下之前的红色背景了。
