ListView with Custom Adapter

The Android Development Tutorials blog contains Basic as well as Advanced android tutorials.Go to Android Development Tutorials to get list of all Android Topics.

Populate ListView with Custom Adapter

ListView can be populated by ArrayAdapter, Database, ArrayList etc
In this post I will describe how to populate ListView using a Custom Adapter.

Have a look at my previous post
Populating ListView with Database
Populating ListView with ArrayList

ListView with Custom Adapter Example

In this example I have created a listView  and populated it with Custom Adapter.
Each of the ListView item contain two views
TextView SMS Sender : to show SMS Sender Number
TextView SMSBody : to show the SMS Body/content

Here the ListView shows the all the SMSes with Sender Number and SMSBody.

What we need to do ..
Create a Custom Adapter
and add/set  the adapter to ListView.

Add the following permission in your manifest file to read the SMS..
   <uses-permission android:name="android.permission.READ_SMS"/>
   <uses-permission android:name="android.permission.WRITE_SMS"/>

listview_activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#D1FFFF"

        android:dividerHeight="0.1dp"
        android:divider="#0000CC"
        >
    </ListView>
   
  </LinearLayout>

listview_each_item.xml
