【问题描述】:
我创建了一个应用程序,我可以在其中从设备获取联系人。 但我想从结果中删除重复的联系人。
我该怎么做?
MainActivity
public class MainActivity extends Activity implements OnItemClickListener {
EditText searchText;
ArrayList<String> phno0 = new ArrayList<String>();
List<String> arrayListNames;
public List<ProfileBean> list;
public SearchableAdapter adapter;
//ProfileBean bean;
String[] cellArray = null;
String contacts;
ListView lv;
String phoneNumber, name;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActionBar actionBar = getActionBar();
lv = (ListView) findViewById(R.id.listview);
list = new ArrayList<ProfileBean>();
getAllCallLogs(this.getContentResolver());
adapter = new SearchableAdapter(getApplication(), list);
lv.setAdapter(adapter);
lv.setItemsCanFocus(false);
lv.setOnItemClickListener(this);
lv.setTextFilterEnabled(true);
}
@Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
}
public void getAllCallLogs(ContentResolver cr) {
Cursor phones = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,
null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME
+ " ASC");
while (phones.moveToNext()) {
phoneNumber = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
name = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
list.add(new ProfileBean(name, phoneNumber));
}
phones.close();
}
}
