[英]Recycler view not scrolling
當我在內部和回收站視圖中使用選項卡布局時,我有一個片段視圖,問題是回收站視圖根本不滾動,為什么有什么主意?
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
app:elevation="0dp"
tools:context="com.carmen.carmen.fragment.dashboard">
<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.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_below="@+id/toolbar"
android:background="#FFFFFF"
android:layout_gravity="center_horizontal"
app:tabSelectedTextColor="#000000"
app:tabTextColor="#000000"
app:elevation="0dp"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<android.support.v7.widget.RecyclerView
android:id="@+id/serviceView"
android:layout_width="match_parent"
app:layout_anchor="@+id/tab_layout"
app:layout_anchorGravity="bottom"
android:layout_gravity="bottom"
android:layout_height="wrap_content"
android:scrollbars="vertical"
/>
<include layout="@layout/active_service_sheet" />
</android.support.design.widget.CoordinatorLayout>
</FrameLayout>
當我將填充物添加到回收站視圖時,它可以工作,但是它在選項卡布局中占用了空間
您可以嘗試在NestedScrollView
粘貼RecyclerView
NestedScrollView
<android.support.v4.widget.NestedScrollView
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:layout_gravity="fill_vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<android.support.v7.widget.RecyclerView
android:id="@+id/serviceView"
android:layout_width="match_parent"
app:layout_anchor="@+id/tab_layout"
app:layout_anchorGravity="bottom"
android:layout_gravity="bottom"
android:layout_height="wrap_content"
android:scrollbars="vertical"
/>
</android.support.v4.widget.NestedScrollView>
將此屬性添加到您的CoordinatorLayout
app:layout_behavior="@string/appbar_scrolling_view_behavior"
或做這樣的事情:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
app:elevation="0dp"
tools:context="com.carmen.carmen.fragment.dashboard">
<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.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_below="@+id/toolbar"
android:background="#FFFFFF"
android:layout_gravity="center_horizontal"
app:tabSelectedTextColor="#000000"
app:tabTextColor="#000000"
app:elevation="0dp"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<LinearLayout 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:orientation="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
>
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical" />
</LinearLayout>
<include layout="@layout/active_service_sheet" />
</android.support.design.widget.CoordinatorLayout>
</FrameLayout>
在必須在CoordinatorLayout
滾動的視圖中,您必須編寫以下參數: app:layout_behavior=""@string/appbar_scrolling_view_behavior""
將以下行添加到您的coordinatorlayout
app:layout_behavior="@string/appbar_scrolling_view_behavior"
或者您創建如下相同的內容。
main_activity.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
android:id="@+id/main_layout"
android:orientation="vertical"
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"
tools:context=".MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- our toolbar -->
<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="60sp"
android:background="@color/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:popupTheme="@style/ThemeOverlay.AppCompat.Light"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_scrollFlags="scroll|enterAlways">
<TextView
android:id="@+id/side_toolbar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=""
android:textSize="20sp"
android:textStyle="bold" />
</android.support.v7.widget.Toolbar>
<!-- our tablayout to display tabs -->
<android.support.design.widget.TabLayout
android:id="@+id/tabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
</android.support.design.widget.AppBarLayout>
<!-- View pager to swipe views -->
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
並在片段布局中創建Recyclerview,如下面的代碼
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
android:id="@+id/main_layout"
android:orientation="vertical"
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"
tools:context=".MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- our toolbar -->
<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="60sp"
android:background="@color/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:popupTheme="@style/ThemeOverlay.AppCompat.Light"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_scrollFlags="scroll|enterAlways">
<TextView
android:id="@+id/side_toolbar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=""
android:textSize="20sp"
android:textStyle="bold" />
</android.support.v7.widget.Toolbar>
<!-- our tablayout to display tabs -->
<android.support.design.widget.TabLayout
android:id="@+id/tabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
</android.support.design.widget.AppBarLayout>
<!-- View pager to swipe views -->
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
並創建一個布局以將其附加到recyclerview。 像下面的代碼
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="220dp"
android:layout_height="150dp"
android:layout_margin="5dp">
<ImageView
android:id="@+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/img4"
android:scaleType="fitXY"
android:text="Category"
android:gravity="center"
tools:ignore="DuplicateIds" />
<TextView
android:id="@+id/id"
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="@drawable/transparent_strip"
android:text="Today's Deals"
android:paddingTop="12dp"
android:paddingBottom="12dp"
android:textSize="18dp"
android:textColor="#FFFFFF"
android:gravity="center"
android:layout_centerInParent="true"/>
</RelativeLayout>
