i am retriving mobile contact data to my app using ListView but data display two time in the List. help me how to Control of displaying contact two times.
I Refered and many solution through web , yet i am not able to sove.
i attached code below:
public class MainActivity extends AppCompatActivity implements AdapterView.OnItemClickListener {
private static final int PERMISSIONS_REQUEST_READ_CONTACTS = 100;
List<String> name1 = new ArrayList<String>();
List<String> phno1 = new ArrayList<String>();
MyAdapter ma ;
Button select;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.display);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && checkSelfPermission(Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.READ_CONTACTS}, PERMISSIONS_REQUEST_READ_CONTACTS);
getAllContacts(this.getContentResolver());
ListView lv = (ListView) findViewById(R.id.lv);
ma = new MyAdapter();
lv.setAdapter(ma);
lv.setOnItemClickListener(this);
lv.setItemsCanFocus(false);
lv.setTextFilterEnabled(true);
}else {
getAllContacts(this.getContentResolver());
ListView lv = (ListView) findViewById(R.id.lv);
ma = new MyAdapter();
lv.setAdapter(ma);
lv.setOnItemClickListener(this);
lv.setItemsCanFocus(false);
lv.setTextFilterEnabled(true);
}
select = (Button) findViewById(R.id.button1);
select.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v) {
StringBuilder checkedcontacts= new StringBuilder();
System.out.println(".............."+ma.mCheckStates.size());
for(int i = 0; i < name1.size(); i++)
{
if(ma.mCheckStates.get(i)==true)
{
checkedcontacts.append(name1.get(i).toString());
checkedcontacts.append("\n");
}
else
{
System.out.println("Not Checked......"+name1.get(i).toString());
}
}
Toast.makeText(MainActivity.this, checkedcontacts,Toast.LENGTH_SHORT).show();
}

}
#Override

}
}}
my output :
It is because storage is returning the contacts twice ,they'll be duplicated because of google contacts,so when you retrieve just put a condition to exclude contacts which are already in.
public void getAllContacts(ContentResolver cr) {
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.SORT_KEY_PRIMARY);
while (phones.moveToNext())
{
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
if(!phno1.contains(phoneNumber)) { // check wether contact already exists
name1.add(name);
phno1.add(phoneNumber);
}
}
phones.close();

You can do that in two steps:
Build a filterable list - How to make a nice looking ListView filter on Android
And create a search interface.
I create a listview get all contact from address book of Android. I try to update listview by onResume() but It's not working.
Here is my code:
public class Display extends Activity implements OnItemClickListener{
List<String> name1 = new ArrayList<String>();
List<String> phno1 = new ArrayList<String>();
List<String> email1 = new ArrayList<String>();
MyAdapter ma ;
ListView lv;
int countContact;
TextView textViewManyCount;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.display);
getAllContacts(this.getContentResolver());
lv= (ListView) findViewById(R.id.lv);
ma = new MyAdapter();
lv.setAdapter(ma);
lv.setOnItemClickListener(this);
lv.setItemsCanFocus(false);
lv.setTextFilterEnabled(true);
textViewManyCount = (TextView) findViewById(R.id.textViewManyCount);
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
}
public void getAllContacts(ContentResolver cr) {
Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
countContact = phones.getCount();
while (phones.moveToNext())
{
String name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String email = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
System.out.println(".................."+phoneNumber);
name1.add(name);
phno1.add(phoneNumber);
email1.add(email);
}
phones.close();
}
class MyAdapter extends BaseAdapter implements CompoundButton.OnCheckedChangeListener
{ private SparseBooleanArray mCheckStates;
LayoutInflater mInflater;
TextView textViewName,textViewPhone,textViewEmail;
MyAdapter()
{
mCheckStates = new SparseBooleanArray(name1.size());
mInflater = (LayoutInflater)Display.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return name1.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
#Override

}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View vi=convertView;
if(convertView==null)
vi = mInflater.inflate(R.layout.list_user, null);
textViewName = (TextView) vi.findViewById(R.id.textViewName);
textViewPhone = (TextView) vi.findViewById(R.id.textViewPhone);
textViewEmail = (TextView) vi.findViewById(R.id.textViewEmail);
textViewName.setText("Name :"+ name1.get(position));
textViewPhone.setText("Phone No :"+ phno1.get(position));
textViewEmail.setText("Email :"+ email1.get(position));
textViewManyCount.setText("Contacts: "+countContact);
return vi;
}
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
// TODO Auto-generated method stub
}
}
When I running app, It's load all contact but when I click button Home and change some information in Address book then click icon app to open app again. And onResume() method not working.
Here my onResume()
#Override
protected void onResume()
{
super.onResume();
if (lv != null)
{
updateData();
}
}
private void updateData()
{
getAllContacts(this.getContentResolver());
ma = new MyAdapter();
lv.setAdapter(ma);
ma.notifyDataSetChanged();
}
So some body help me! Plz!
Try by Replacing your updateData():
private void updateData()
{
getAllContacts(this.getContentResolver());
ma.notifyDataSetChanged();
}
You may be referencing an old ListView (lv) that is not the new ListView you see when you resume your Activity. Try getting the reference to lv again using Activity.findViewById(R.id.xxxx) in onResume().
You could also try reusing the old adapter instead of creating a brand new one (by clearing it and updating it's content). If you're reusing the old adapter, just make sure you give the old adapter to the new ListView using ListView.setAdapter(ma).
You should also have MyAdapter.getItemId(int position) return position instead of 0.

Now in ArrayList name1 I am having list of all name of my device..
and in name2 i am having Arraylist of some selcected person..Now i want to match both of this array list and display name in list that is present....
I am working on this since last week..stuck here .. Please help me...
Thanks ...:)
Don't panic, just match both list and take one temp arraylist and when any name match then add in that temp arraylist and then show that list view according to that temp arraylist. :)
Here I give you code and hint:
ArrayList<String> matchname = new ArrayList<String>();
for(int k =0;k<name1;k++)
{
for(int l =0;l<name2.size();l++)
{
String keyname = name1[k];
if((keyname.trim().equals(name2[l].trim())))
{
matchname.add(keyname);
}
}
}
I am trying to create a application for android. in which at one point i need to open a activity i need to display all the contacts on user's phone in a listview with checkbox, so that multiple contacts can be selected. I have written a code which currently shows the list of all the contacts but without checkbox as you can see in the image attached. Next, when the user selects the required contacts using checkbox and clicks on DONE button the result should be derived in main activity and all the contacts which the user selected should be displayed in the EditText like this Frank <+911234567890>, John <+913456789012>, Ashley <+911237890456>,. How can i achieve what i want? And also the dashes(-) which are currently getting displayed should also disappear.
Use the following to add checkboxes on all the items:
listView.setChoiceMode(CHOICE_MODE_MULTIPLE);
Not only will this add checkboxes to all the items, but it will handle all the check states for you. You have several methods you can use to get the state of the items:
getCheckedItemCount()
getCheckedItemIds()
getCheckedItemPositions()
And you can use setItemChecked() to set any item's checked state programmatically. Take a look at this tutorial for a guide how to make a multiple selection list.
split the string on each '-' using function split("-") and then concatenate it.
use the code snippet below to retrieve all contacts from the phonebook,append them in a ListView containing checkboxes to enable multiple selection,,it is clear and straight to the point.
