用法
1.普通效果
//清单文件中要设置主题为NoActionBarStatusBarUtils.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ActionBarStatusBarUtils.with(this).setIsActionBar(true).clearActionBarShadow().setDrawable(getResources().getDrawable(R.drawable.shape)).init();
自定义渐变shape
