android – Cardview with dividers in it-ThrowExceptions

Exception or error:

I’ve seen those CardViews (I’m not sure they’re even CardViews) with dividers used in a lot of apps, so I’m guessing there is an easy way to create them.
I wanted to ask how is it exactly done? are those even CardViews?

I couldn’t find out more about them because I didn’t know the name of the View exactly, so If someone could direct me to an example with code I’d be grateful.

Image example:

How to solve:

You can use this code this may help

###

The shown screenshot shows a normal CardView with views as divider in-between.
There is no DividerView or something similar if you searching for something like this. Just use a simple View with a height and a background.

I’ve something similar in a library of mine. I use this to create the divider:

<View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@color/stroke"/>

card_library.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:orientation="vertical"
              android:paddingBottom="8dp">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="8dp"
        android:layout_marginRight="8dp"
        android:gravity="center_vertical"
        android:orientation="horizontal">

        <TextView
            android:id="@+id/libraryname"
            style="@style/CardTitle"
            android:fontFamily="sans-serif-condensed"
            android:textStyle="normal"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:maxLines="1"/>

        <TextView
            android:id="@+id/libraryversion"
            style="@style/CardTitle"
            android:fontFamily="sans-serif-condensed"
            android:textStyle="normal"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="4dp"
            android:layout_marginTop="4dp"
            android:gravity="left|bottom"
            android:maxLines="1"
            android:textSize="12sp"/>

        <TextView
            android:id="@+id/librarycreator"
            style="@style/CardTitle"
            android:fontFamily="sans-serif-condensed"
            android:textStyle="normal"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="2dp"
            android:gravity="right"
            android:maxLines="2"
            android:textSize="14sp"/>
    </LinearLayout>

    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:layout_marginTop="4dp"
        android:background="@color/stroke"/>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        android:padding="4dp">

        <TextView
            android:id="@+id/description"
            style="@style/CardText"
            android:fontFamily="sans-serif-condensed"
            android:textStyle="normal"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="8dp"
            android:maxLines="20">
        </TextView>
    </LinearLayout>

</LinearLayout>

It will then look like this:

Divider

Set app:cardElevation=”0dp” then use a View – see below

<android.support.v7.widget.CardView
android:id="@+id/cv"
xmlns:android="http://schemas.android.com/apk/res/android"
app:cardElevation="0dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto">

<!-- Insert UI elements -->

    <View
        android:layout_width="fill_parent"
        android:background="@android:color/darker_gray"
        android:layout_height="2dp"/>

</android.support.v7.widget.CardView>
