Filterable ListView in Android

In this article, we are going to create a filterable listview application in Android. Filterable listview means that, whenever user types in some text, correspondingly the items in the listview will be filtered.

1. Create an Android project namely “ListViewFilterable”

Figure 1: Create new Android Project

2. Select a build target for this application

Figure 2: Select Android API Level

3. Enter the application details

Figure 3: Enter application details

4. Open and update the file /res/layout/main.xml with the given below code :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/listview"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
    />

</LinearLayout>

5. Open and update the file /src/in/wptrafficanalyzer/listviewfilterable with the given below code :

package in.wptrafficanalyzer.listviewfilterable;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MainActivity extends Activity {
    String[] countries = new String[] {
        "India",
        "Pakistan",
        "Sri Lanka",
        "China",
        "Bangladesh",
        "Nepal",
        "Afghanistan",
        "North Korea",
        "South Korea",
        "Japan"
    };

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // Creating an array adapter to host the list view items
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, countries);

        // Get the reference of listview from the main layout
        ListView listView = (ListView) findViewById(R.id.listview);
        listView.setAdapter(adapter);

        // This statement enables text filtering in the listview
        listView.setTextFilterEnabled(true);

    }
}
