PreferenceFragment在CollapsingToolbarLayout中没有滚动 [英] PreferenceFragment no scroll in CollapsingToolbarLayout

问题描述

我对PreferenceFragment和CollapsingToolbarLayout有问题.我有一个基本布局:

I have a problem with PreferenceFragment and CollapsingToolbarLayout. I have a base layout:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/mainLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".activities.base.BaseActivity">

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbarLayout"
    android:layout_width="match_parent"
    android:layout_height="@dimen/nav_header_height"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/ctlLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <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="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            android:minHeight="?attr/actionBarSize"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            app:layout_collapseMode="pin"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"></android.support.v7.widget.Toolbar>

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

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

<FrameLayout
    android:id="@+id/fragment_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:nestedScrollingEnabled="true"/>

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fabFav"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginRight="85dp"
    android:src="@android:drawable/ic_menu_save"
    app:layout_anchor="@id/appbarLayout"
    app:layout_anchorGravity="bottom|right|end"
    android:visibility="gone" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fabShare"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="@dimen/fab_margin"
    android:src="@android:drawable/ic_menu_share"
    app:borderWidth="0dp"
    app:layout_anchor="@id/appbarLayout"
    app:layout_anchorGravity="bottom|right|end"
    android:visibility="gone" />

<fragment
    android:id="@+id/search_fragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="com.eventum.raedictionary.fragments.SearchFragment"
    tools:layout="@layout/fragment_search"/>

问题是，当我使用PreferenceFragment向Framelayout充气时，滚动无法正常工作，但正常的Fragment可以正常工作.

The problem is when I inflate the Framelayout with a PreferenceFragment the scroll doesn't work but with a normal Fragment works properly.

        BaseSettingFragment settingsFragment = new BaseSettingFragment();

        fragmentTransaction = getFragmentManager().beginTransaction();

        fragmentTransaction.setCustomAnimations(R.transition.fade_in, R.transition.fade_out);

        fragmentTransaction.replace(R.id.fragment_container, settingsFragment);

        fragmentTransaction.commit();

我没有找到解决此问题的任何方法，有人可以帮助我吗?

I haven't found any solutions for this problem, can anyone help me?

谢谢.

PD:对不起，我的英语.

PD: Sorry for my English.

推荐答案

PreferenceFragment基于ListView，它不支持CollapsingToolbarLayout所需的嵌套滚动API.您可以改为使用首选项支持库和

PreferenceFragment is based on ListView, which does not support the nested scrolling APIs required for CollapsingToolbarLayout. You can instead use the Preference Support Library and PreferenceFragmentCompat, which is based on RecyclerView and does support the nested scrolling APIs required.
