I've manged to use the following code for retrieving user's contacts into a list, and now I'm working on the next step (getting individual info of each contact):
package com.example.mycontacts;
import android.app.LoaderManager;
import android.content.Context;
import android.content.CursorLoader;
import android.content.Loader;
import android.database.Cursor;
import android.graphics.Color;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.support.v4.app.ListFragment;
import android.widget.CursorAdapter;
import android.widget.SimpleCursorAdapter;
/**

public class ContactListFragment extends ListFragment implements LoaderManager.LoaderCallbacks<Cursor> {
private CursorAdapter mAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// create adapter once
Context context = getActivity();
int layout = android.R.layout.simple_list_item_1;
Cursor c = null; // there is no cursor yet
int flags = 0; // no auto-requery! Loader requeries.
mAdapter = new SimpleCursorAdapter(context, layout, c, FROM, TO, flags);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// each time we are started use our listadapter
setListAdapter(mAdapter);
// and tell loader manager to start loading
getActivity().getLoaderManager().initLoader(0, null, (android.app.LoaderManager.LoaderCallbacks<Cursor>) this);
}
// columns requested from the database
private static final String[] PROJECTION = {
ContactsContract.Contacts._ID, // _ID is always required
ContactsContract.Contacts.DISPLAY_NAME_PRIMARY // that's what we want to display
};
// and name should be displayed in the text1 textview in item layout
private static final String[] FROM = { ContactsContract.Contacts.DISPLAY_NAME_PRIMARY };
private static final int[] TO = { android.R.id.text1 };
@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
// load from the "Contacts table"
Uri contentUri = ContactsContract.Contacts.CONTENT_URI;
// no sub-selection, no sort order, simply every row
// projection says we want just the _id and the name column
return new CursorLoader(getActivity(),
contentUri,
PROJECTION,
null,
null,
null);
}
@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
// Once cursor is loaded, give it to adapter
mAdapter.swapCursor(data);
}
@Override
public void onLoaderReset(Loader<Cursor> loader) {
// on reset take any old cursor away
mAdapter.swapCursor(null);
}
}
The problem is, I can't find a way to get the info from each contact, in the onItemClick() of the list. Any idea?
EDIT I actually added:
ListView newsList = new ListView(getActivity());
newsList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
but didn't know how to proceed and how interact with cursor.
EDIT2
I changed it from listfragment to dialogFragment with a listview, but still I don't get the contact's number by pressing on the item (in list). what am I misiing here?
