話不多說，首先看下效果
fragment沉浸式.gif
背景
在開發(fā)中搀矫，我們可能會(huì)遇到這樣的需求，首頁有多個(gè)fragment刻肄，有的fragment需要實(shí)現(xiàn)沉浸式瓤球，其余不需要實(shí)現(xiàn)，如上圖所示敏弃，實(shí)現(xiàn)方式有很多種卦羡，下面介紹其一種
思路（其實(shí)很簡(jiǎn)單，思路明確了很好理解）
1麦到、假如MainActivity中有多個(gè)fragment绿饵，沉浸式透明效果在MainActivity實(shí)現(xiàn)
2、測(cè)量出狀態(tài)欄高度瓶颠，單獨(dú)給需要實(shí)現(xiàn)沉浸式的fragment布局設(shè)置高度
實(shí)現(xiàn)步驟
或許大多數(shù)人都會(huì)用這個(gè)庫 StatusBarUtil
注：個(gè)人習(xí)慣把工具拷貝到項(xiàng)目中拟赊，以減少apk體積，文章最后貼一下此工具代碼
1粹淋、在MainAcitivity實(shí)現(xiàn)沉浸式：
/**
* 可放到onCreate或者BaseActivity
*/
protected void setStatusBar() {
StatusBarUtil.setTranslucentForImageViewInFragment(this, 0, null);
}
2要门、為需要實(shí)現(xiàn)沉浸式fragment XML布局中新增一個(gè)View
<View
android:id="@+id/view_status_bar"
android:layout_width="match_parent"
android:layout_height="0dp" />
3虏肾、在需要實(shí)現(xiàn)沉浸式fragment onCreateView中設(shè)置2步驟ID的高度
@BindView(R.id.view_status_bar)
View mViewStatusBar;
protected void initData() {
StatusBarUtil.setStatusViewAttr(mViewStatusBar, getActivity());
}
4、注：setStatusViewAttr此方法在第三方庫中沒有欢搜，是我自己添加的
打完收工封豪，就如此簡(jiǎn)單，下面貼一下所需工具
