I am attempting to add spacing between views in the RecyclerView. Using the RecyclerView I have a repeating list of constraint views using a view adapter. On each constraint view I have set the layout margin to equal 15dp like so android:layout_margin="15dp"
. When previewing the layout in design view I can see that the margin is being applied however when the app is compiled the RecyclerView.
The XML for the view being used inside the RecyclerView is as follows:
<android.support.constraint.ConstraintLayout 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="wrap_content"
android:layout_margin="15dp"
android:background="@drawable/gradient"
android:clipToPadding="true"
android:minHeight="0dp">
<TextView
android:id="@+id/moment_timestamp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="20dp"
android:layout_marginTop="16dp"
android:text="28 MAR @ 2:45pm"
android:textColor="@android:color/white"
app:layout_constraintEnd_toStartOf="@+id/moment_text"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="@+id/moment_text"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"
android:layout_marginEnd="20dp"
android:layout_marginStart="20dp"
android:layout_marginTop="40dp"
android:background="@android:color/transparent"
android:includeFontPadding="false"
android:paddingVertical="0dp"
android:text="A kind man held the door open for me today"
android:textAlignment="viewStart"
android:textColor="@android:color/white"
android:textSize="25sp"
android:textStyle="bold"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/moment_timestamp" />
</android.support.constraint.ConstraintLayout>
In design view, the component I am designing looks like this:
However, when compiled and being used in the RecyclerView, the margins are not applied:
This is my code where I inflate the layout. Originally the width of the view was not being applied so as shown in this answer I changed my code.
View view = inflater.inflate(R.layout.text_moment, null, false);
RecyclerView.LayoutParams lp = new
RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
view.setLayoutParams(lp);
return new MomentViewHolder(view);
Searched around quite extensively now and can't seem to find a solution.
Try to to this:
<android.support.constraint.ConstraintLayout 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="wrap_content"
android:layout_marginBottom="15dp" //This line is the important one
android:background="@drawable/gradient"
android:clipToPadding="true"
android:minHeight="0dp">
Or what i always do:
<android.support.constraint.ConstraintLayout 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="wrap_content"
android:padding="16dp" //This line is the important one
android:background="@drawable/gradient"
android:clipToPadding="true"
android:minHeight="0dp">
I've managed to figure out the solution. It turns out the answer that I followed to try and resolve the width issue was causing the margin issue. Instead of setting null as the ViewGroup parameter on the inflate function, I have now passed ViewGroup into the inflate function like so:
View view = inflater.inflate(R.layout.text_moment, viewGroup, false);
