用法

1.普通效果

 //清单文件中要设置主题为NoActionBar StatusBarUtils.with(this)                .setColor(getResources().getColor(R.color.blue))                .init();

2.图片背景效果

 //清单文件中要设置主题为NoActionBar//在布局文件中设置的第一个view的背景图片则为当前状态栏背景图片 StatusBarUtils.with(this)                .init();

3.侧滑页面状态栏效果

 //清单文件中要设置主题为NoActionBar//R.id.rl_content为主页面布局//代码中设置的为主页面状态栏//在侧滑页面布局文件中设置的第一个view的背景图片则为侧滑状态栏背景图片      StatusBarUtils.with(this)                .setDrawerLayoutContentId(true, R.id.rl_content)                .setColor(getResources().getColor(R.color.blue))                .init();

4.自定义渐变状态栏

 //当前案例含ActionBar    StatusBarUtils.with(this)                .setIsActionBar(true)                .clearActionBarShadow()                .setDrawable(getResources().getDrawable(R.drawable.shape))                .init();

自定义渐变shape
