Это хороший учебник о том, как получить контактный номер с помощью контент-провайдера в Android

и

и может выбрать контактный номер, как это
добавить событие нажатия кнопки, например
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
i = new Intent(Intent.ACTION_PICK,
ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(i, PICK_CONTACT);
}
});
//outside button click
public void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
switch (reqCode) {
case (PICK_CONTACT):
if (resultCode == Activity.RESULT_OK) {
getContactInfo(data);
}
}
}
// onActivityResult
private void getContactInfo(Intent data) {
// TODO Auto-generated method stub
ContentResolver cr = getContentResolver();
Cursor cursor = managedQuery(data.getData(), null, null, null, null);
while (cursor.moveToNext()) {
String contactId = cursor.getString(cursor
.getColumnIndex(ContactsContract.Contacts._ID));
Name = cursor
.getString(cursor
.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
String hasPhone = cursor
.getString(cursor
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
Cursor emailCur = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{contactId}, null);
emailCur.close();
if (hasPhone.equalsIgnoreCase("1"))
hasPhone = "true";
else
hasPhone = "false";
if (Boolean.parseBoolean(hasPhone)) {
Cursor phones = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = " + contactId, null, null);
while (phones.moveToNext()) {
phoneNo = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
}
pname.setText(Name);
//
phno.setText(phoneNo);
Toast.makeText(this, Name + " " + phoneNo, Toast.LENGTH_SHORT).show();
}
}
