How to Develop Auto Complete Search Using Code in Android Application

Hello everyone,

When you use a Search Engine Website, like Google or Bing, you type one or two character, the engine will give you some completed keywords or results. I will help you to find exactly what you want to find. So in Android Application, you can also do that, and it is very simple. Not, let’s start it.

For Example:

To do this demo, you have to know about TextWatcher and AutoCompleteTextView

1 – Create new project: File -> New -> Android Application ProjectDemoAutoSearch.

 

2 – Open main_activity.xml in res/layout and type following code:

P/S: android:completionThreshold=”1″ means that the complete result will be displayed when user inputs 1 character in search field. If you want the complete result is displayed when you input 2 characters, change android:completionThreshold to 2.

3 – Open MainActivity.java in res/com.devandroidtips.demoautosearch/src and type following code

4 – OK, now use your Autocomplete search application.
