Android实现修改状态栏背景、字体和图标颜色的方法

前言:

Android开发,对于状态栏的修改,实在是不友好,没什么api可以用,不像ios那么方便.但是ui又喜欢只搞ios一套.没办法.各种翻源码,写反射.真的蛋疼.

需求场景:

当toolbar及状态栏需要为白色或浅色时(如简书),状态栏由于用的Light风格Theme,字体,图标也都是白色,会看不清.如果改变成黑色就很和谐了.

一.修改状态栏颜色:

改变状态栏颜色,可以看看这篇文章.传送门:实现状态栏(statusbar)渐变效果其实很简单

传送门实现的效果:

这种方法实现的状态栏变色,没有黑色背景.

使用全屏模式实现的效果如下(QQ的效果):

很明显的黑色背景.

我用的手机是华为,系统7.0

二.修改状态栏字体:

通用工具类:

activity中使用:

?

1

StatusBarUtil.setStatusBarLightMode(getWindow());

效果:

出现的问题:

1.statusbar背景色变成了colorPrimaryDark默认颜色,但是我的配置是白色背景(具体配置代码见最后).

分析原因:

setSystemUiVisibility()会刷新view的属性配置.由于statusbar默认使用colorPrimaryDark属性.所以颜色会变回默认颜色

此时步骤一设置背景的方法就会失效.

private void initStatusBar() {

  }

  if (statusBarView != null) {

    statusBarView.setBackgroundResource(MVPConfig.statusDrawable);

  }

}

原因:当传入的resid相同时,就不会再次去设置背景色.

    return MVPConfig.isStatusBar();

  }

//子类通过复写该方法,控制是否需要改变statusbar字体颜色

  protected boolean isStatusBarLight() {

    return MVPConfig.isStatusBarLight;

  }

四.补充:

6.0以下,5.0原生系统无法修改字体颜色,用了个比较取巧的办法,设置成半透明灰色.

   }

 }

由于是直接修改window中的statusbarview的背景,而frgament依赖于activity,所以在activity与fragment直接跳转时,状态栏不是很适用.比如:activity是蓝色,fragment需要是白色,fragment需要通过window修改状态栏颜色.有点麻烦.
