I'm doing a search in a Listiview where I rescue the phone contacts. After many attempts I have not succeeded in this and I do not understand very well what could be the error. I'd appreciate your help. Here I attach my code.
MainActivity with BaseAdapter:
public class Contactos extends AppCompatActivity{
private ListView listView;
Toolbar toolbar;
private MyAppAdapter myAppAdapter;
private ArrayList<Item_contactos> postArrayList;
public static final int REQUEST_READ_CONTACTS = 79;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.contactos);
listView = (ListView) findViewById(R.id.lista_contactos);
listView.setEmptyView(findViewById(R.id.mensajevacio));
postArrayList = new ArrayList<>();
getSupportActionBar().hide();
toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.inflateMenu(R.menu.menu_contactos);
Cursor c = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" ASC");
CargarLista(c);
}
protected void CargarLista(Cursor c) {
if (c != null && c.getCount() > 0) {
try {
HashSet<String> normalizedNumbersAlReady = new HashSet<>();
int normalizedNumber = c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER);
int DisplayName = c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
int DisplayNumber = c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
int DisplayType = c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE);
while (c.moveToNext()){
String normalized = c.getString(normalizedNumber);
if (normalizedNumbersAlReady.add(normalized)) {
String nombre = c.getString(DisplayName);
String telefono = c.getString(DisplayNumber);
String tipo = c.getString(DisplayType);
String sType = "";
switch (tipo) {
case "0":
sType = "Otro";
break;
case "1":
sType = "Casa";
break;
case "2":
sType = "Movil";
break;
case "3":
sType = "Trabajo";
}
postArrayList.add(new Item_contactos(nombre, telefono, sType));
