How do I remove the extra space in this recyclerview element in Android? - android-layout

Question

I'm implementing a Recycler View in Android to create a list, but for some reason I see a space in between two elements, and I'm not able to pinpoint the error location. As to why is this happening, my guess is on the row element XML.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Answer 1

It is because of recycler view height. Try to change recyclerview height to wrap_content.And in cardview layout in linear-layout use height wrap_content.
try this code for your cardview:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:cardview1="http://schemas.android.com/apk/res-auto"
android:id="#+id/row_top_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.CardView
android:id="#+id/pos_cv"
android:layout_width="match_parent"
android:layout_height="72dp"
android:clickable="true"
android:layout_marginBottom="10dp"
cardview1:cardCornerRadius="6dp"
cardview1:cardElevation="4dp"
cardview1:cardMaxElevation="6dp">
<TextView
android:id="#+id/manager1"
android:layout_width="220dp"
android:layout_height="wrap_content"
android:layout_marginLeft="30dp"
android:layout_marginTop="15dp"
android:text="Store Manager/Branch"
android:textSize="14sp"
android:textStyle="bold" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="70dp"
android:orientation="horizontal">
<TextView
android:id="#+id/retail"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_marginLeft="30dp"
android:layout_marginTop="30dp"
android:text="Abc Retail"
android:textSize="10sp" />
<View
android:layout_width="170dp"
android:layout_height="match_parent" />
<TextView
android:id="#+id/amount"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="30dp"
android:text="25,000"
android:textColor="#color/colorDarkPink"
android:textSize="14sp"
android:textStyle="bold" />
</LinearLayout>
<TextView
android:id="#+id/address"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_marginLeft="30dp"
android:layout_marginTop="50dp"
android:text="Abc Retail"
android:textSize="10sp" />
</android.support.v7.widget.CardView>
</LinearLayout>

Try to decrease your values
android:layout_height="50dp"
if it will not work try to decrease values in other views
