Android Adding Search Functionality to ListView
Adding search functionality to listview will filters the list data with a matching string, hence provides user an easy way to find the information he needs. In this tutorial i am discussing how to enable search filter to android ListView.
1. Create a new project in Eclipse File New ⇒ Android ⇒ Application Project and fill the required details.
2. Create required files needed to generate a listview. I am using my default activity_main.xml as listview and created a new xml file for single listitem named list_item.xml. Also make sure that you have created a EditText above the listview which will be used to search the listview.
activity_main.xml
list_item.xml
3. Now open your MainActivity.java and paste the following code to create a simple ListView. In the following code i stored all the list data in an array called products[] and attached to listview using simple ArrayAdapter.
Enabling Search Functionality
4. Search functionality can be enabled by writing simple lines of code. All you need to do is adding addTextChangedListener to EditText. Once user enters a new data in EditText we need to get the text from it and passing it to array adapter filter. All the following code in your MainActivity.java
5. Finally add the following property in your AndroidManifest.xml file to hide the keyboard on loading Activity.
AndroidManifest.xml
Final Code:

Nice, Great Tut. but i was wondering how i can put another page in each item, example: when i click Dell Inspiron, it will go to dell inspiron page that has its definitions/descriptions
Thanks for your help
It is very simple, put switch cases in the listadapter ‘s onitemclick listener and in each switch cases, start an activity of your choice 😉
Edit :
Try this, worked for me:
@Override
public void onItemClick(AdapterView parent, View view,int position, long _id) <
String values = adapter.getItem(position);
// TODO Auto-generated method stub
Intent i =null;
if (values==”1,000 Hours”) <
i=new Intent(Allsongs.this, Thousandhours.class);
startActivity(i);>
if (values==”16″) <
i=new Intent(Allsongs.this, Sixteen.class);
startActivity(i);>
if (values==”2000 Light Years Away”) <
i=new Intent(Allsongs.this, Lightyears.class);
startActivity(i);>
if (values==”21 Guns”) <
i=new Intent(Allsongs.this, Guns.class);
startActivity(i);

How to get a video attached with a hashtag into a search bar for the user to serarch the video from there?
This is great. However, there is one thing that I don’t understand. The full search capability (letters that start in the middle), works sometimes and not others. For example, type s and you’ll see it properly finding all listitems that have s. Type e, and you don’t see the same result.
I assume you normally use
String product = products[position];
to determine which product was selected ?
If that’s the case just replace it by:
String product = adapter.getItem(position);

Hello, I have a Question. Can I implement this code using an andorid Fragment in spite of Activity? Problem is the line ” MainActivity.this.adapter.getFilter().filter(cs); ” give me an error: NullPointerException.
I use all the code you have in my fragment activity, including
// ArrayList for Listview>
inputSearch = (EditText) view.findViewById(R.id.inputSearch);
public void onTextChanged(CharSequence cs, int start, int before, int count) <
// When user changed the Text
how to add details of that device so that if we click on that we should get details
woh! that reminds me again to check the documentation before going deeply in implementing anything. I was working on this from scratch unaware of the existence of such filtering API. yet this solution not retrieving the whole list that contains the ‘keyword’, instead it retrieves a list of the strings that start by the ‘keyword’. thank you so much!
I have a problem
Example:
String[] products = < “One”, “Two”,
“Three”, “Four”, “Five”, “Six”,
“Seven”,
Now I search for f
Then Four and five will come in list view
So position is changed. But I need position before list
view change. Because I will pass this position another activity. Then that activity
access a database by this position.
What Can I don now?
Send me code I will check out your issues than I vil rectify and provide you solution.
get an long ID instead of position
