标签: android-appbarlayout

我在CoordinatorLayout和RecyclerView内使用AppBarLayout，CollapsingToolbarLayout创建了折叠式透明搜索栏。让recyclerView出现在appBarLayout的后面而不是在它的下面是很多技巧。但正在工作。我的问题是，有时候，当我向下滚动时，应用程序栏不会重新进入。我只是在屏幕外不可见。这是我的布局：

<android.support.design.widget.CoordinatorLayout
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    app:expandedTitleMarginBottom="88dp">

<android.support.v7.widget.RecyclerView
    android:id="@+id/services_recycler_view"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    app:behavior_overlapTop="88dp">

</android.support.v7.widget.RecyclerView>

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fitsSystemWindows="true"
        android:background="@color/color_transparent"
        app:elevation="0dp">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_scrollFlags="scroll|enterAlways"
        android:fitsSystemWindows="false">

<Button
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Search Location or Service"
    android:id="@+id/button_search_bar"/>



    </android.support.design.widget.CollapsingToolbarLayout>

</android.support.design.widget.AppBarLayout>

</android.support.design.widget.CoordinatorLayout>

解决不重新进入问题的任何帮助将是巨大的。

另一个问题是，因为我使用的app:behavior_overlapTop="88dp"是使recyclerView出现在应用程序栏的后面，所以整个滚动有些奇怪：它首先滚动appBar，然后滚动回收器视图。任何更好的解决方案都是值得欢迎的。

编辑： 我意识到AppBar确实在向下滚动时重新输入，但是是不可见的（我可以单击它，我只是看不到它）。我想我会分享这个新线索=）

我有AppBarLayout，CollapsingToolbarLayout和工具栏活动。从代码设置标题和字幕。最初，我希望工具栏隐藏并在Appbar布局折叠时显示，使用我的代码可以正常工作（最初隐藏工具栏），但始终显示工具栏标题和副标题。仅在应用栏布局完全折叠时如何显示标题

<android.support.design.widget.AppBarLayout
    android:id="@+id/app_bar"
    android:layout_width="match_parent"
    android:layout_height="@dimen/app_bar_height"
    android:fitsSystemWindows="true"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/toolbar_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        app:titleEnabled="false"
        app:contentScrim="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_collapseMode="pin"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

    </android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>

设置标题和字幕

 Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowHomeEnabled(true);
    getSupportActionBar().setTitle("Title");
    getSupportActionBar().setSubtitle("sutitle");

CoordinatorLayout增加AppBarLayout和之间的空间RecyclerView.不知道是否它的Toolbar或AppBarLayout.

手机上呈现的布局的屏幕截图:

Studio上的设计渲染并不是这个空间的方式.

我在AppBarLayout中使用了CollapsingToolbarLayout,用户可以使用setExpanded(boolean)AppBarLayout中的方法展开或折叠它.

问题是动画很慢而且不流畅.

我正在搜索,似乎支持设计库存在问题(请阅读此问题).但我不能降级我的支持设计库因为Im使用BottomSheetBehavior,我得到这个错误:

Error:(88) No resource identifier found for attribute 'behavior_hideable' in package...
Error:(88) No resource identifier found for attribute 'behavior_peekHeight' in package...

有什么建议可以提高setExpand的速度吗？

我正在尝试在折叠AppbarLayout时对ImageView产生淡化效果,但图像仍然存在.我已经阅读了其他解决方案,但它不适用于我.我似乎无法找到代码的错误.

我们遇到的太多这些崩溃主要发生在Samsung 6.0.1设备上.我们甚至使用相同的操作系统版本获得相同的设备,但仍无法自行重现.我们得到的其他膨胀异常可能与他们有关.

这个问题有解决方法吗？

支持lib版本 - 24.2.1

所以我一直得到一个"java.lang.RuntimeException:这个图包含循环依赖"错误,我很确定是由我从AppBarLayout.ScrollingViewBehavior扩展的行为引起的.我有一个使用此行为的AppBarLayout布局,如果我删除行为,错误消失.这是行为的错误和代码

另外,appbar布局和折叠工具栏布局之间有什么区别？

非常感谢 :)

无法更改工具栏标题，我在中manifeast.xml也设置了标题setTitle("TITLE");

我将标题设置为“ 历史记录和报告”，但它显示不同的标题通知，这是另一个活动标题。

我检查了一下，manifeast.xml 但没有任何变化，任何人都可以帮忙。

这是我的代码

public class Nav_HistoryAndReports extends AppCompatActivity {

private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setTitle("History & Reports");
    setContentView(R.layout.nav_history_and_reports);

    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setToolbar(toolbar);

    viewPager = (ViewPager) findViewById(R.id.viewpager);
    setupViewPager(viewPager);

    tabLayout = (TabLayout) findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(viewPager);
}

public void setToolbar(Toolbar toolbar) {
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}

private void setupViewPager(ViewPager viewPager) {
    ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
    adapter.addFragment(new FragmentHistoryAndReports_Visits(), "VISITS");
    adapter.addFragment(new FragmentHistoryAndReports_Visitors(), "VISITORS");
    adapter.addFragment(new …

我在折叠工具栏上遇到了一些问题。我有以下布局结构

<CoordinatorLayout>
    <AppbarLayout>
        <CollapsingToolbar>
    <NestedScrollView>
        <HorizontalRecyclerView>
    </NestedScrollView>
</CoordinatorLayout>

仅当我尝试滚动NestedScrollView触摸时才会出现问题HorizontalRecyclerView。在那种情况下CollapsingToolbar不会崩溃。只需AppbarLayout停留在该位置并NestedScrollView在其下方滚动即可。我已附上一个视频，其中的所有内容都很清晰。谁能解释这个问题？谢谢。
