I have a tags_frame in the FoodCardFragment (whose layout can be found here) that is used for displaying a RecyclerView in the TagsFragment. The layout of TagsFragment is simply:
<android.support.v7.widget.RecyclerView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start" />
The RecyclerView uses either StaggeredGridLayoutManager or LinearLayoutManager. However, as you can see from the middle of my cardview, this RecyclerView (composed of round-corner rectangles) uses StaggeredGridLayoutManager and it is centered. And actually in another activity I used LinearLayoutManager it is also centered.
How can I align it to the left (start) of the card?
You can try this in your fragment_tags.xml:
<android.support.v7.widget.RecyclerView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/recycler_view"
android:layout_width="wrap_parent"
android:layout_height="match_parent"
android:layout_gravity="start" />
Use wrap_content for layout_width.
This happens because you are constraint your FrameLayout to parent on both sides and set width as match_parent. You have more options, One is to set gravity start to your framelayout or set width of the framelayout as wrap_content and constraint only to start.

I have no idea how this can happen, but I have a ConstraintLayout with a CardView inside. Inside said CardView is a LinearLayout. That LinearLayout overlaps the parent on the end. Check the screenshot for more info. If I remove the android:layout_margin from the cardView, the inner layout looks good again, but adding margin to start seems to just push the entire layout to and over the end of the parent. It doesnt matter what sort of layout is used inside the CardView. The issue affects them all.
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:animateLayoutChanges="true"
android:background="#color/colorWhite">
..
<androidx.cardview.widget.CardView
android:id="#+id/wakeuptimer_status_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="#dimen/md_keylines"
app:layout_constraintTop_toTopOf="parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
.....
You need to change the Linearlayout height to match-parent instead of wrap_content. With wrap_content you aren't restricting the size of the Linearlayout view to the size of the CardView.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
I have wrapped an activity in an scroll view like following.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
>
<include layout="#layout/content_form" />
</ScrollView>
I have around 15 fields in the content_form layout, the issues is that the last item in content_form layout is attached with bottom.
I need to add a margin below the scroll view, i have tried giving margin to scrollviewand the last item of content_form field, but nothing is working.
I need to know how to add margin at the bottom of page when using scroll view.
If you want the scrolling margin to be within the content, it would be best to add it to content_form. You should be able to accomplish this by either adding paddingBottom to your parent container in that layout, or layout_marginBottom on your last view aligned to the parent bottom.
This make padding under the last item in scroll view. may be good for you
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:paddingBottom="80dp"
android:clipToPadding="false"
android:layout_height="match_parent">
You can either use Space or View for the purpose like
<Space
android:layout_width="100dp"
android:layout_height="match_parent"/>
Or,
<View
android:layout_width="100dp"
android:layout_height="match_parent"
android:layout_weight="1"/>
Here, you need to give padding, not margin.
Try giving padding to the ScrollView.
I've had issues with ScrollView being ill-behaved when it's direct childview is not a LinearLayout. So please try LinearLayout as direct child of your scrollView and place <include> layout inside LinearLayout.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
... your layouts go here ...
</LinearLayout>
</ScrollView>
I want to implement two RecyclerView with different layout in single activity. The above RecyclerView should scroll vertical and the one below should scroll horizontal. But when I run the app, only either one RecyclerView is displayed. If first view is displayed then it works properly and scrolls vertical, while second RecyclerView is missing. And if second one is displayed then it scrolls vertical when it should do horizontal scroll and the first RecyclerView is missing.
Here is what i want. Source: Github,CardView-Recyclerview-Picasso
Here is my layout
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorBackgroundLight"
android:smoothScrollbar="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView
android:id="#+id/CategoriesRecyclerView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/videoRecyclerView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="130dp"
android:layout_below="#+id/CategoriesRecyclerView"/>
</RelativeLayout>
</android.support.v4.widget.NestedScrollView>
You may directly use the 2 Recycler Views without NestedScrollView.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView
android:id="#+id/CategoriesRecyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/videoRecyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="130dp"
android:layout_below="#+id/CategoriesRecyclerView"/>
</RelativeLayout>
And in your CategoriesRecyclerView whose height is wrap_content, use setAutoMeasureEnabled(true) on the Layout manager used for the recyler view.
If you want to scroll the horizontal scrollview full upside on page scroll then use scrollview otherwise you can do without scrollview. Also to achieve your layout just give the horizontal recyclerview fixed height and then you can see both recyclerview .
When I have my RecyclerView height as wrap_content, as below
<android.support.v7.widget.RecyclerView
android:id="#+id/myRecyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
The result as below.
The is because the resize happens before the animation.
It is described more clearly in
https://medium.com/#elye.project/recyclerview-supported-wrap-content-not-quite-f04a942ce624#.n7xivnrdr
Is there a way to force it to animate first then only resize?
I hava a layout below:
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
</android.support.v7.widget.RecyclerView>
the recyclerView using LinearLayoutManager, a item of recyclerView is another recyclerView which using GridLayoutManager, set the gridLayoutRecyclerView's height, but the gridLayoutRecyclerView can not scroll inner
try this code
<android.support.v7.widget.RecyclerView
android:id="#+id/my_recycler_view"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
and also refer about this http://developer.android.com/training/material/lists-cards.html
After checking implementation, the reason appears to be the following. If RecyclerView gets put into a ScrollView, then during measure step its height is unspecified (because ScrollView allows any height) and gets equal to minimum height (as per implementation) which is apparently zero.
You have couple of options for fixing this:
Set a certain height to RecyclerView
Set ScrollView.fillViewport to true
Or keep RecyclerView outside of ScrollView.
If RecyclerView height is not limited - which is the case when it's put into ScrollView - then all Adapter's views have enough place vertically and get created all at once.
This is my out recyclerView's layout
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
</android.support.v7.widget.RecyclerView>
then, a item of out recyclerView have another RecyclerView's which using GridLayoutManager, this is the code of the item below:
<android.support.v7.widget.RecyclerView
android:id="#+id/seatRecyclerView"
android:layout_width="match_parent"
android:layout_height="200dp"
/>
the seatRecyclerView can't not to scroll
