我最近将手机更新为Android 5.0.2，我正在开发的应用程序中有一个闪烁的工具栏。工具栏被向上推，并被最顶部的状态栏部分隐藏。
会导致此问题的原因是什么？
以下是具有处理工具栏

工具栏的XML布局
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="56dp"
android:elevation="4dp"
android:background="@color/primary_blue"
app:popupTheme="@style/Theme.AppCompat.Light.DarkActionBar"
app:theme="@style/AppTheme.Title"/>
答案 0 :(得分：4)
删除android:fitsSystemWindows="true"或在DrawerLayout中的第一个元素内移动工具栏（添加LL，因为DrawerLayout可以处理2个视图）。
