Recycler view showing single item

Question

I am facing a strange error where recyclerview is showing only a single item. Below is code for my recyclerview adapter :

public class ChatAdapter extends Re         


        

Answer 1

content_main.xml as follows

android:layout_width="match_parent"
android:layout_height="match_parent"

IN row_list.xml file make following changes

android:layout_width="match_parent"
android:layout_height="wrap_content"

I make above changes it runs.

Answer 2

Don't use match_parent for height for your item view. One item fills whole screen vertically so you don't see another.

Answer 3

My mistake was I accidentally used:

LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false)

instead of:

LinearLayoutManager(context, LinearLayoutManager.VERTICAL, false)

Answer 4

Try changing the layout used in your item view to FrameLayout. Here is an example.

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/item"
    android:layout_width="match_parent"
    android:layout_height="?listPreferredItemHeight"
    android:clickable="true"
    android:focusable="true"
    android:foreground="?selectableItemBackground">

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginBottom="8dp"/>
</FrameLayout>

Answer 5

when you are creating row.xml for recyclerview should follow these things:

1. Always use "wrap_content" for the height of the row otherwise in "match_parent" it will occupy the whole screen for a single row.

2. You can also take the height in dp.

Answer 6

1) if your recyclerview is vertical then set height of recyclerview match_parent and row_item.xml height also match_parent

2) if your recyclerview is horizontal then set Width of recyclerview match_parent and row_item.xml Width also match_parent

for ex:- Horizontal RecyclerView

<android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="60dp"
        android:layout_marginRight="60dp" />

row_item.xml

<TextView
android:layout_width="match_parent"
android:layout_height="180dp"
android:layout_marginBottom="5dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="5dp"
android:background="@drawable/rect"
android:gravity="center"
android:maxLines="2"
android:padding="10dp"
android:textColor="@color/white"
android:textSize="25sp" />
