how to scroll over image in recycler view - java

I am new to android programming and I am trying to scroll my recycler view over image
<?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>
When I scroll ,the recycler view scrolls under the image not over it.How can i achieve this effect ?


Try this:-
Using FrameLayout by setting backgroundImage:
<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>
Using LinearLayout by setting backgroundImage:
<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>
Using RelativeLayout by setting backgroundImage:
<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>
Using RelativeLayout with ImageView:
<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>

RecyclerView Item doesn't fit when using CollapsingToolbarLayout

In RecyclerView in xml design
How do I fully display the last text?
When you see the image, you will notice that the last text (TextView)
Only a small part of it is visible and the rest of the text is hidden on the screen
Here is my list_item xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingLeft="72dp"

android:paddingRight="16dp"
android:paddingBottom="16dp">
<TextView
android:id="#android:id/text1"
android:layout_width="match_parent"

<TextView
android:id="#android:id/text2"
android:layout_width="match_parent"
android:layout_height="wrap_content"

Why did this problem happen?
This is my layout code.
<?xml version="1.0" encoding="utf-8"?>

</layout>

Solution
You can add either android:focusableInTouchMode="true" or android:descendantFocusability="blocksDescendants" to the child layout in NestedScrollView
Try below code in your layout:
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
...... >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusableInTouchMode="true" >
...........

Finally, According to https://stackoverflow.com/users/6891563/khemraj comment, I Find
Mey solution ...
Just add android:focusableInTouchMode="true" to ImageView Like this :
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:bind="http://schemas.android.com/apk/res/android" >
<data>
<variable
name="aboutMbti"
type="mbtitest.kiars.me.mbti.model.AboutMbti"/>
</data>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:cardBackgroundColor="#android:color/white"
app:cardCornerRadius="2dp"
app:cardElevation="5dp" >
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:fitsSystemWindows="true"
android:scrollbarSize="1dp"
android:scrollbarThumbVertical="#android:color/white">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">

Prevent FAB from going down when scrolling in RecyclerView in fragment

I'm new to android development and recently learning about fragments.
I have a recyclerview inside fragment, and I want it to be attached to the toolbar, I tried put app:layout_behavior="#string/appbar_scrolling_view_behavior"
inside the container layout but whenever the toolbar shows the FAB moves down below the navigation bar as you can see here.

Thanks.

I think you must specify your layout target,
in this way:
<android.support.design.widget.FloatingActionButton
...
android:layout_gravity="bottom|end|right"
app:layout_anchor="#id/notes"
app:layout_anchorGravity="bottom|right|end"
/>

Recycler View Position Bottom of ImageView

I'm learning Android Material from Slidenerd's video on Youtube. I got a problem when learn to make Recycler View on Drawer. But the position of Recycler View can't bottom of Image View. I want to throw that after the ImageView like another Material Design app. Let see the screenshot.
This is my code:
fragment_navigation_drawer.xml
<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"

android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- TODO: Update blank fragment layout -->
<ImageView
android:layout_width="280dp"
android:layout_height="140dp"
android:layout_marginBottom="18dp"
android:src="#drawable/bg_galungan"
/>
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/drawer_list"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.support.v7.widget.RecyclerView>
</FrameLayout>
custom_row.xml
<?xml version="1.0" encoding="utf-8"?>

android:id="#+id/listIcon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_bookmark1"
android:layout_gravity="center_vertical"
/>
<TextView
android:id="#+id/listText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Doa Sehari-hari"
android:layout_gravity="center_vertical"

tools:layout="#layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>
Let's share if you also has same problem. Thanks for advance !

If it really not necessary to user FrameLayout as your parent, you can use RelativeLayout like I used.
<?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="match_parent"
android:layout_height="match_parent"
android:background="#EEE"
tools:context="com.balinez.wdharmana.doahindu.NavigationDrawerFragment">
<LinearLayout
android:id="#+id/containerDrawerImage"
android:background="#F88C00"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<!-- TODO: Update blank fragment layout -->
<ImageView
android:layout_width="280dp"
android:layout_height="140dp"
android:layout_marginBottom="18dp"
android:src="#drawable/beach"
/>
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/drawer_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/containerDrawerImage"
>
</android.support.v7.widget.RecyclerView>
</RelativeLayout>

Drop shadow on fragments with a listview and scrollview

I'm having an issue with a ListView and a ScrollView and adding a drop shadow between the listview and the ScrollView.
I had made a shape, which works great with a ListView and a relative layout, but does not work with the ScrollView.
I have done the following - Dashboard List
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="8dp"
android:paddingRight="8dp">
<ListView
android:id="#id/android:list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:choiceMode = "singleChoice"
android:listSelector="#31ABD4"
android:drawSelectorOnTop="false"/>
<TextView android:id="#id/android:empty"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="No data"/>
</RelativeLayout>
Dashboard with scroll view
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/white" >
<View
android:layout_width="10dp"
android:layout_height="fill_parent"
android:background="#drawable/shadow_left" />
</RelativeLayout>
</ScrollView>
View
<?xml version ="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:angle="180"
android:width="10dp"
android:centerX="0.1"
android:gravity="right"
android:startColor="#00000000"
android:endColor="#55000000"
android:type = "linear"
/>
</shape>
Edit - Attached Screenshots
Thank you all,
James

seems that you are missing the paddings on "Dashboard with scroll view"
try this instead
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="8dp"
android:paddingRight="8dp" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/white" >
<View
android:layout_width="10dp"
android:layout_height="fill_parent"
android:background="#drawable/shadow_left" />
</RelativeLayout>
</ScrollView>
