因?yàn)橛许?xiàng)目需要開(kāi)發(fā)一個(gè)淺色調(diào)背景的Activity且需要狀態(tài)欄沉浸式樣式，但目前Android4.4.4以上支持沉浸但在Android6.0以下不支持黑色內(nèi)容的狀態(tài)欄文字圖標(biāo)，所以寫(xiě)了一個(gè)單獨(dú)的Activity類做實(shí)現(xiàn)：

需注意，
使用方式是將自己工程中的Activity extends BaseActivity即可；
需要使用吐司和log產(chǎn)生提示和日志時(shí)非特殊需求可以使用BaseActivity自帶的toast()方法和log()方法來(lái)執(zhí)行；
BuildConfig以及R類需要根據(jù)工程單獨(dú)引用；
其次，在Activity的xml中需要一個(gè)LinearLayout來(lái)進(jìn)行狀態(tài)欄占位，Activity中的內(nèi)容可放在一個(gè)RelativeLayout并將RelativeLayout的android:layout_below設(shè)為"@+id/sys_statusBar"
的具體代碼如下：
<LinearLayout
android:id="@+id/sys_statusBar"
android:layout_width="fill_parent"
android:layout_height="0.1dp"
android:orientation="vertical"
android:visibility="gone">
</LinearLayout>
在Activity的onCreate方法中執(zhí)行setStatusBarHeight();即可完成工作。
