我在 NestedScrollView 中使用 webview,它允许我在滚动时隐藏和显示工具栏,但存在问题。工具栏和汉堡包的标题可见 Image< >
这是主视图代码
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="0dp"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<ProgressBar
android:id="@+id/progressbar_Horizontal"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="10dp"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:indeterminate="true"
android:indeterminateTint="@color/header_back_ground"
android:max="100" />
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipe_refresh"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/progressbar_Horizontal">
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/nested_scroll_view"
android:fitsSystemWindows="true"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<WebView
android:id="@+id/web"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true" />
</android.support.v4.widget.NestedScrollView>
</android.support.v4.widget.SwipeRefreshLayout>
</RelativeLayout>
这是来自 app_bar_main 的代码
