Search a listview based on input in EditText

     public class MainActivity extends Activity {
private ListView lv,lv2;
private EditText et;
String listview_array[]={"01634 ABOHAR","080 Bangalore","011 Delhi","Dell Inspiron", "HTC One X", "HTC Wildfire S", "HTC Sense", "1234", "iPhone 4S", "Samsung Galaxy Note 800", "Samsung Galaxy S3", "MacBook Air", "Mac Mini", "MacBook Pro"};
private ArrayList array_sort = new ArrayList();
int textlength = 0;

public void onCreate(Bundle savedInstanceState)

{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    lv = (ListView) findViewById(R.id.ListView01);
    lv2 = (ListView) findViewById(R.id.ListView02);
    et = (EditText) findViewById(R.id.EditText01);
    lv.setAdapter(new ArrayAdapter(this,
    android.R.layout.simple_list_item_1, listview_array));
    int x= lv.getHeaderViewsCount ();
    System.out.println("x========"+x);
    lv.setAdapter(new ArrayAdapter
    (MainActivity.this,
    android.R.layout.simple_list_item_1, listview_array));

    et.addTextChangedListener(new TextWatcher()
    {
        public void afterTextChanged(Editable s)
        {
            // Abstract Method of TextWatcher Interface.

        }
        public void beforeTextChanged(CharSequence s,
        int start, int count, int after)
        {

            // Abstract Method of TextWatcher Interface.

        }
        public void onTextChanged(CharSequence s,
        int start, int before, int count)
        {
            textlength = et.getText().length();
            array_sort.clear();
            for (int i = 0; i < listview_array.length; i++)
            {
                if (textlength <= listview_array[i].length())
                {

                    String s2= et.getText().toString();
                    if(listview_array[i].toString().contains(et.getText().toString()))
                    {
                        array_sort.add(listview_array[i]);
                    }


                }
            }

            lv.setAdapter(new ArrayAdapter
            (MainActivity.this,
            android.R.layout.simple_list_item_1, array_sort));
        }
    });

}
 }
