Ich habe eine Aktivität, die eine AppToolbar neben einer RecyclerView, die unter der Toolbar befindet angezeigt wird. Jede Reihe der RecyclerView ist eine CardView. Mein Problem ist, dass die RecyclerView überhaupt nicht scrollt. Es scheint, dass es keine Gestenrückrufe erhält.Android Recycler Ansicht scrollt nicht
Hier ist mein Haupt-Layout xml:
<?xml version="1.0" encoding="utf-8"?>
<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:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:background="@color/colorActivityBackground"
tools:context=".MainActivity">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/rv"
android:scrollbarAlwaysDrawVerticalTrack="true"
android:scrollbars="vertical"
android:fadeScrollbars="true"
app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
<include layout="@layout/tool_bar" />
<include layout="@layout/nav_drawer_layout" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="@dimen/fab_margin"
android:src="@drawable/ic_add"
app:layout_anchor="@id/rv"
app:layout_anchorGravity="bottom|end" />
</android.support.design.widget.CoordinatorLayout>
Edit: Hier ist das Werkzeug Strichcode:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.AppBarLayout android:id="@+id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="false"
android:theme="@style/AppTheme.AppBarOverlay"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="4dp"
android:theme="@style/AppTheme.AppBarOverlay"
app:layout_collapseMode="pin"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
Auch hier ist das Layout mein nav ist Schublade:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize">
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<android.support.v7.widget.RecyclerView
android:id="@+id/right_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#99ccff" />
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
Und Hier ist meine Hauptaktivität, in der ich meine Recycler-Ansicht bearbeite:

Von dem, was Sie gepostet haben, sieht alles so aus, als sollte es funktionieren. Posten Sie tool_bar, nav_drawer_layout und den Code, den Sie zum Füllen der Recycler-Ansicht verwenden. –
Ich habe diese Codes zum Beitrag hinzugefügt –
Wow, du hast da viel vor. Ich bin mit DrawerLayout nicht sehr vertraut, aber ich glaube nicht, dass Sie es wie beabsichtigt verwenden, und ich bin verwirrt, warum Sie zwei Recycler-Ansichten haben. Sehen Sie sich diese Antwort an, um zu erfahren, wie Coordinator-, AppBar- und Drawer-Layouts interagieren sollten: http://StackOverflow.com/a/33413334/1224186 –
