Custom ListView
After creating simple ListView, android also provides facilities to customize our ListView.
As the simple ListView, custom ListView also uses Adapter classes which added the content from data source (such as string array, array, database etc). Adapter bridges data between an AdapterViews and other Views
Example of Custom ListView
In this custom listview example, we are adding image, text with title and its sub-title.
Structure of custom listview project
activity_main.xml
Create an activity_main.xml file in layout folder.
File: activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:paddingLeft="@dimen/activity_horizontal_margin"

Customize Our ListView
Create another java class MyListView.java which extends ArrayAdapter class. This class customizes our listview.
MyListView.java
package com.example.test.listviewwithimage;
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class MyListAdapter extends ArrayAdapter<String> {
private final Activity context;
private final String[] maintitle;
private final String[] subtitle;
private final Integer[] imgid;
public MyListAdapter(Activity context, String[] maintitle,String[] subtitle, Integer[] imgid) {
super(context, R.layout.mylist, maintitle);
// TODO Auto-generated constructor stub
this.context=context;
this.maintitle=maintitle;
this.subtitle=subtitle;
this.imgid=imgid;
}
public View getView(int position,View view,ViewGroup parent) {
LayoutInflater inflater=context.getLayoutInflater();
View rowView=inflater.inflate(R.layout.mylist, null,true);
TextView titleText = (TextView) rowView.findViewById(R.id.title);
ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
TextView subtitleText = (TextView) rowView.findViewById(R.id.subtitle);
titleText.setText(maintitle[position]);
imageView.setImageResource(imgid[position]);
subtitleText.setText(subtitle[position]);
return rowView;
};
}
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class MyListAdapter extends ArrayAdapter<String> {
private final Activity context;
private final String[] maintitle;
private final String[] subtitle;
private final Integer[] imgid;
public MyListAdapter(Activity context, String[] maintitle,String[] subtitle, Integer[] imgid) {
super(context, R.layout.mylist, maintitle);
// TODO Auto-generated constructor stub
this.context=context;
this.maintitle=maintitle;
this.subtitle=subtitle;
this.imgid=imgid;
}
public View getView(int position,View view,ViewGroup parent) {
LayoutInflater inflater=context.getLayoutInflater();
View rowView=inflater.inflate(R.layout.mylist, null,true);
TextView titleText = (TextView) rowView.findViewById(R.id.title);
ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
TextView subtitleText = (TextView) rowView.findViewById(R.id.subtitle);
titleText.setText(maintitle[position]);
imageView.setImageResource(imgid[position]);
subtitleText.setText(subtitle[position]);
return rowView;
};
}
