search filter using edittext from sqlite listview

my listview is happening correctly its fetching from sqlite database. but my problem is i have added edittext to filter by name . so if i enter any letter in my edittext it should filter accordingly. but its not happening . Below is my code.

MainActivity.java
 public void afterTextChanged(Editable arg0) {
                    // TODO Auto-generated method stub
                    ArrayList<StudentEntity> listentity = new ArrayList<StudentEntity>();
                    String texto="";
                    texto=inputSearch.getText().toString();

                     String DB_PATH = "/data/data/com.naman.namrathasrinivas.choultriesbangalore" + "/databases/";
                     String DB_NAME = "Marriage.sqlite";
                    String mypath = DB_PATH + DB_NAME;
                    db = SQLiteDatabase.openDatabase(mypath, null,
                            SQLiteDatabase.OPEN_READWRITE);
                    String selectQuery = "SELECT * FROM hall WHERE name LIKE '%\" + texto + \"%' ";
                     Cursor cursor = db.rawQuery(selectQuery, null);
                    if (cursor.moveToFirst()) {
                        do {
                            StudentEntity sentity = new StudentEntity();
                            sentity.setName(cursor.getString(1));
                            sentity.setLocality(cursor.getString(12));


                            listentity.add(sentity);
                        } while (cursor.moveToNext());
                    }




                }
