I am sending the string from my activity to the layout that is created as a common layout with data binding but it's not working. I have checked a lot of answers but nothing is working for me.
I want the same thing as the OP wants in following question, but the solution he accepted is not working for me.
Passing string to included layout via data binding not working
following is my layout resume_detail_heading.xml
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"

I have a layout which need to be scrollable.This is a fragment and the fragment hosted on a activity.The ScrollView has only one child which is relativeLayout and the relativeLayout has multiple child.But i still get the error.The error occured when i install and open the screen,after 5 or 6 second,the app is crashed.

I try to use NestedScrollView but problem not fix.I wrap the fragment layout scroll view with FrameLayout which is found from stack overflow answer.But this did not work.
I want the layout inside my fragment to scroll completely and place it above the softkeyboard whenever keyboard opens. But the problem is the layout is not even scrolling when i user click on keyboard. It covers up some part of the layout.
I have tried many SO threads already but none of them seems to be working.

I've been using the new Androidx libraries and have run into an issue I cannot fix. I am using RecyclerView and just cannot get the row to wrap. It is supposed to do it, and everything I read seems to be that it just works if I cannot get it right. I have used this previously and did not have this issue. I've tried adjusting every setting in both my main layout and the item layout, but nothing seems to affect it. Any help would be appreciated.

OK in my case , in item.xml, the height was given "match_parent". After I converted it into "wrap_content", the recycle view height was expanded according to the number of items. Note that I am using the androidx library as well.
The item.xml code was like this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="horizontal"
android:padding="#dimen/small_padding">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/tickred"
android:layout_marginStart="0dp"
android:layout_marginTop="1dp"
android:layout_gravity="top"
android:layout_marginEnd="#dimen/dimen_margin_between_text"/>
<androidx.appcompat.widget.AppCompatTextView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:id="#+id/serviceTv"
android:layout_gravity="top"
android:gravity="top"
app:fontFamily="#font/lato_regular"
android:textColor="#color/black"
android:textSize="#dimen/dimen_text_smallx"/>
</LinearLayout>
I changed the container height to wrap_content and the recycleview takes its height accordingly.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="horizontal"
android:padding="#dimen/small_padding">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/tickred"
android:layout_marginStart="0dp"
android:layout_marginTop="1dp"
android:layout_gravity="top"
android:layout_marginEnd="#dimen/dimen_margin_between_text"/>
<androidx.appcompat.widget.AppCompatTextView
android:layout_width="0dp"

android:layout_height="wrap_content"

This question already has an answer here:
A scroll view can have only one child Android XML file
(1 answer)
Closed 5 years ago.
Trying to get back coding in android. Why do my program crash when I add another TextView to my XML file?
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:layout_height="match_parent"
tools:context="com.example.oscarorellana.physicscalaculators.Math.CompAnalysis">
<TextView
android:layout_width="match_parent"
android:layout_height="50dp"
android:text="Enter a complex number below"
android:textSize="20dp"
android:textStyle="bold"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="TEST"
/>
</android.support.v4.widget.NestedScrollView>
The XML file is my content file in one of my Android Activities. Probably really basic, but I can't find the mistake.
NestedScrollView should have only one direct child. Add a new Linear/Relative layout as a container or TextViews.
Try this:
<NestedScrollView>
<LinearLayout>
<TextView>
<TextView>
<LinearLayout>
<NestedScrollView>
Update your XML as below:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
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"

<LinearLayout

<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="TEST" />

Try this code : You need to add child under the scroll view , Then only the scroll view will work:
