I am implementing an application where I show information from a database in a RecyclerView and in the use CardView (This RecyclerView is in a fragment), my problem is that the CardView does not respect the property "match_parent" as shown in the image
My CardView code is this:
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="@+id/cardView"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:clickable="true"
android:focusable="true"
android:foreground="?android:attr/selectableItemBackground"
card_view:cardBackgroundColor="#e2e2e2"
card_view:layout_constraintEnd_toEndOf="parent"
card_view:layout_constraintStart_toStartOf="parent"
card_view:layout_constraintTop_toTopOf="parent">
</android.support.v7.widget.CardView>
Searching the forum I found some related questions where they said that I would add a parent to the CardView, by doing it solves the problem but that does not have onclick every element of the ReciclerView and I do not understand why.
Another solution I found was adding:
WindowManager windowManager = (WindowManager)v.getContext().getSystemService(Context.WINDOW_SERVICE);
int width = windowManager.getDefaultDisplay().getWidth();
v.setLayoutParams(new RecyclerView.LayoutParams(width, RecyclerView.LayoutParams.MATCH_PARENT));
This also solved me halfway since I remove the margin of the CardView as shown in the image
After that I tried to add margin to the RecyclerView by inflating the view but it was a failure.
I would really appreciate it if someone could help me out, thanks ...
