android: how to fetch data from sqlite and display in gridview

i have 150 records in sqlite database i want to display 1 row from database in grid view. user will enter a code in edit text and i want to select record on the basis of that code from the database and display in the gridview. I've used the following method to get data from database but i don't know how to insert values in grid view.

method for getting retrieving data from sqlite public String[][] SelectDocData( String drcode) { // TODO Auto-generated method stub try { String arrData[][] = null; SQLiteDatabase db; db = this.getReadableDatabase(); // Read Data String strSQL = "select * from crm_dr_view where dr_code = drcode" ; Cursor cursor = db.rawQuery(strSQL, null); if(cursor != null) {

  if (cursor.moveToFirst()) {
  arrData = new String[cursor.getCount()][cursor.getColumnCount()];

 int i= 0;
 do {               
 arrData[i][0] = cursor.getString(0);
 arrData[i][1] = cursor.getString(1);
 arrData[i][2] = cursor.getString(2);
 i++;

} while (cursor.moveToNext());                     
}}

cursor.close();
return arrData;

} catch (Exception e) {

return null;
}

}

public class Attendance_setup extends Activity {

 String drCode;
 Date currDate;
 EditText ed_shift, ed_drcode;
 String currentTime;
 Button btn_SaveAttendance;
 Db_sqlite sqlite;
 TextView tv;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.attendance); 

    sqlite = new Db_sqlite(Attendance_setup.this);

    ed_shift = (EditText) findViewById (R.id.shift);
    ed_drcode = (EditText)findViewById (R.id.drcode);

    btn_SaveAttendance =(Button)findViewById(R.id.button1);

    btn_SaveAttendance.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub


    drCode =    ed_drcode.getText().toString();
    Log.i("dr code", drCode);
    String[][] data = sqlite.SelectDocData(drCode);

    final GridView gView1 = (GridView)findViewById(R.id.gridView1);
    gView1.setAdapter(new DataAdapter(this));
    sqlite.close();

    }
});
