Java 如何在“回收器”视图中滚动图像

Java 如何在“回收器”视图中滚动图像,java,android,Java,Android,我是android编程新手,我正在尝试在图像上滚动我的回收器视图 <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/rootRL" android:orientation="vertical" android:layout_width="fill_parent" an

我是android编程新手,我正在尝试在图像上滚动我的回收器视图

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/rootRL"
 android:orientation="vertical"
 android:layout_width="fill_parent"
 android:layout_height="160dp"
 android:background="@drawable/mydrawable">

<android.support.v7.widget.RecyclerView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="160dp"
    android:id="@+id/rv"/>
</FrameLayout>

当我滚动时,recycler视图会滚动到图像下方而不是上方。我如何才能实现此效果?

尝试以下操作:-

通过设置背景图像使用框架布局:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp"
        android:background="@drawable/tips"
        android:orientation="vertical">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </FrameLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp"
        android:background="@drawable/tips"
        android:orientation="vertical">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </LinearLayout>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp"
        android:background="@drawable/tips">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </RelativeLayout>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp">

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/tips" />

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </RelativeLayout>

通过设置背景图像使用线性布局:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp"
        android:background="@drawable/tips"
        android:orientation="vertical">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </FrameLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp"
        android:background="@drawable/tips"
        android:orientation="vertical">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </LinearLayout>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp"
        android:background="@drawable/tips">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </RelativeLayout>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp">

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/tips" />

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </RelativeLayout>

通过设置背景图像使用RelativeLayout:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp"
        android:background="@drawable/tips"
        android:orientation="vertical">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </FrameLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp"
        android:background="@drawable/tips"
        android:orientation="vertical">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </LinearLayout>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp"
        android:background="@drawable/tips">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </RelativeLayout>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp">

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/tips" />

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </RelativeLayout>

将RelativeLayout与ImageView一起使用:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp"
        android:background="@drawable/tips"
        android:orientation="vertical">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </FrameLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp"
        android:background="@drawable/tips"
        android:orientation="vertical">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </LinearLayout>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp"
        android:background="@drawable/tips">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </RelativeLayout>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/rootRL"
        android:layout_width="match_parent"
        android:layout_height="160dp"
        android:layout_marginTop="160dp">

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/tips" />

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </RelativeLayout>


从recyclerview中删除“android:layout_marginTop=“160dp”,然后重试。@Sabari我想从该点开始滚动如果您正在将图像设置为framelayout的背景图像,您想在该点上滚动recyckerview,我说的对吗?是的,这正是我想要做的。这里,您将framelayout高度设置为160dp,并将recyckerview的margintop设置为160dp。我认为可以将framelayout的margintop设置为160dp,而不是recyckerview。我已经发布了示例代码(4种方法)来实现您的目标。我希望这对你有帮助。
