In Android, ListView let you arranges components in a vertical scrollable list.
In this tutorial, we will show you 2 ListView examples :
- Normal way to display components in
ListView. - Custom array adapter to customize the item display in
ListView.
P.S This project is developed in Eclipse 3.7, and tested with Android 2.3.3.
1. Normal ListView example
In this example, we show you how to display a list of fruit name via ListView, it should be easy and self-explanatory.
1.1 Android Layout file
File : res/layout/list_fruit.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:textSize="20sp" >
</TextView>
1.2 ListView
package com.mkyong.android;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
public class ListFruitActivity extends ListActivity {
static final String[] FRUITS = new String[] { "Apple", "Avocado", "Banana",
"Blueberry", "Coconut", "Durian", "Guava", "Kiwifruit",
"Jackfruit", "Mango", "Olive", "Pear", "Sugar-apple" };
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// no more this
// setContentView(R.layout.list_fruit);
setListAdapter(new ArrayAdapter<String>(this, R.layout.list_fruit,FRUITS));
ListView listView = getListView();
listView.setTextFilterEnabled(true);
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(),
((TextView) view).getText(), Toast.LENGTH_SHORT).show();
}
});
}
}
1.3 Demo
2. Custom ArrayAdapter example
In this example, we show you how to create 4 items in the ListView, and use a custom “ArrayAdapter” to display different images base on the “item name” in the list.
2.1 Images
Get 4 images for demonstration.
2.2 Android Layout file
File : res/layout/list_mobile.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dp" >
<ImageView
android:id="@+id/logo"
android:layout_width="50px"
android:layout_height="50px"
android:layout_marginLeft="5px"
android:layout_marginRight="20px"
android:layout_marginTop="5px"
android:src="@drawable/windowsmobile_logo" >
</ImageView>
<TextView
android:id="@+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@+id/label"
android:textSize="30px" >
</TextView>
</LinearLayout>
2.3 Custom ArrayAdapter
Create a class extends ArrayAdapter and customize the item display in the getView() method.
package com.mkyong.android.adaptor;
import com.mkyong.android.R;
import android.content.Context;
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 MobileArrayAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values;
public MobileArrayAdapter(Context context, String[] values) {
super(context, R.layout.list_mobile, values);
this.context = context;
this.values = values;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.list_mobile, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.label);
ImageView imageView = (ImageView) rowView.findViewById(R.id.logo);
textView.setText(values[position]);
// Change icon based on name
String s = values[position];
System.out.println(s);
if (s.equals("WindowsMobile")) {
imageView.setImageResource(R.drawable.windowsmobile_logo);
} else if (s.equals("iOS")) {
imageView.setImageResource(R.drawable.ios_logo);
} else if (s.equals("Blackberry")) {
imageView.setImageResource(R.drawable.blackberry_logo);
} else {
imageView.setImageResource(R.drawable.android_logo);
}
return rowView;
}
}
2.4 ListView
ListView, but use above custom adapter to display the list.
package com.mkyong.android;
import com.mkyong.android.adaptor.MobileArrayAdapter;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ListView;
import android.widget.Toast;
import android.view.View;
public class ListMobileActivity extends ListActivity {
static final String[] MOBILE_OS =
new String[] { "Android", "iOS", "WindowsMobile", "Blackberry"};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new MobileArrayAdapter(this, MOBILE_OS));
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
//get selected items
String selectedValue = (String) getListAdapter().getItem(position);
Toast.makeText(this, selectedValue, Toast.LENGTH_SHORT).show();
}
}

hey! nice job!
but you should check the convertView before making a new rowView.
Nima Ahmadi you’re right. Here is the modified code:
View rowView = convertView;
if (rowView == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView = inflater.inflate(R.layout.item_menu, parent, false);
}
where to insert this code exactly??

In the “res/layout/list_fruit.xml” file, the “TextView” widget has no “Layout” wrapper around it. Can someone explain why. It doesn’t work when I tried to add a “Layout” wrapper around it and try to add a button or other widgets.
I don’t understand how the “TextView” widget gets turned into a “ListView” widget by the “ListFruitActivity.JAVA” activity. Can someone explain how all these magic potions work together and how can I modify the XML to add another WIDGET without using “Adapter”? Still very confusing. Thank you.

Hi, how i put a multiple listviews in one activity(layout) Example:
—————————–(Inicio pantalla)
| List1
| DATA1
| DATA2
|……
| List2
| DATA1
| DATA2
|……
| List3
| DATA1
————————(Fin de pantalla)
| DATA2
|……
| List4
| DATA1
|……
Use a Hashmap or custom Bean Class instead of a String[]
etc.
also, try filling images a cleaner way, little example:
Note
To post source code in comment, uses
tag, for examples :

thank you very much , can you tell me where I can get tutorial to start new activity from list view?
hi i just want to know what is epub reader could u explain it briefly if possible for u is it done on androi or ios aplication could u provide solution for my problem
Where is your software getting your list titles? I can’t find “List of Fruits” or “List of Mobile OS” anywhere.
Android Manifest
thanks, it`s is very helpful at all
Great!
Although I’m not using images, but rather two different pieces of text for each item in my list (which need to have different formatting), this cleared a lot! It also taught me a fair bit about what an Adapter does and how it goes about doing that. It’s my first Android application ever, and following your example I had it working in just under half an hour (including my own modifications).
Thank you very much!
Can’t get it to work… it keeps crashing and sending this Error: “content must have a listview whose id attribute is ‘android.r.id.list'” any idea why?
Really a nice tutorial. It cleared my concepts.
If I am not wrong list_mobile is called everytime list_view is invoked. My problem is how to add a button on the bottom of list screen? When I gave try it creates the number of buttons.
Great article, to the point and clear.
I think I love you… I mean, Thank you very much!
u prove this, easy does it; nice one dude..thanx.
It really worked thanks a lot!!!

I want to add one footer in this listview (custom adapter e.g. mobileList) , how can i do this?
how I can agree two buttons in botom of the list , XML list_mobile
where I declare events onclick … findViewById ?
I really like this example, but i have a question, what of if i had an explorer binded with listview items of images on sd card, how do i show the thumbnail/preview or icon of those images.
Thanks
hi, you’re example is really explicit and helpful thx for posting such a tutorial!! I have a question though, what happens if i get the images using a web service so i can’t have them stored in a local folder??
Hey there,
I have one question in my mind:
protected void onListItemClick(ListView l, View v, int position, long id) { //get selected items String selectedValue = (String) getListAdapter().getItem(position); Toast.makeText(this, selectedValue, Toast.LENGTH_SHORT).show();In this method i want to use switch case. So need to know can i do that? Cos i’m trying and not getting any result.
e.g switch(position) or switch(v.getId())
Most of examples/tutorials found on internet using if else and use the same code.
Thanks,

i hope you can help
thank you
Hi mkyong,
I like this tutorial and I took your code as basis for my very first android app.
Going on with my app I would like to add a header view (a linear layout of a text field and a button). I stressed google for a solution, but I could not find the right place to inflate the additional view. Would you extend your tutorial or point me to the proper solution?
Thanks,
khan

import com.mkyong.android.R;
import com.mkyong.android.adaptor.MobileArrayAdapter;
thank you.
Hi sora,
Don’t import the project in eclipse or which your using.Try to do it.because some projects cant be import. Or you may try this deleted the import statements like
“import com.mkyong.android.R;
import com.mkyong.android.adaptor.MobileArrayAdapter;”
and then try I think it will works for you.
I have parsed a xml and set the value to list using custom adapter.now how to get the value of particular row after clicking on it.
Awesome! This is the best, cleanest implementation I’ve seen yet and I’ve been searching for awhile for this. Thanks!!

Deepak,
In the listView object call the method setBackgroundColor and pass the color you want to set for the view.
If you want to set color for ever click onItemClick method use below code :
parent.getChildAt(position).setBackgroundColor(Color.BLUE); if (save != -1 && save != position) { parent.getChildAt(save).setBackgroundColor(Color.CYAN); } save = position;Thanks,
Gubs
