Android Api - get mobile number from contacts

I tried so much tutorials, and read a lot here at SO, but i cant solve my problem:

When a button is clicked, the user can choose the mobile number of a contact. Actual I can get the name of the selected contact, but i can't find a way, to get/chose the mobile nu开发者_C百科mber..

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    /** Layouting */
    this.mGetMobileNumberButton = (Button)findViewById(R.id.getMobileNumberButton);
    this.mNameTextView = (TextView)findViewById(R.id.nameTextView);
    this.mMobileNumberTextView = (TextView)findViewById(R.id.mobileNumberTextView);


    /** onClick getContactInfos*/
   this.mGetMobileNumberButton.setOnClickListener(new OnClickListener() {
      public void onClick(View v){ 
          Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
          startActivityForResult(intent, 1);        
      } 
    });
}

@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
    super.onActivityResult(reqCode, resultCode, data);
    if (resultCode == Activity.RESULT_OK) {
        Uri contactData = data.getData();
        Cursor c = managedQuery(contactData, null, null, null, null);
        if (c.moveToFirst()) {
            String name = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
            mNameTextView.setText(name);
        }
    }
}

Hope anyone can help :)

This will get the cursor holding base contact data, and will loop through the phone numbers the contact has, can have multiple.

    Uri uri = data.getData();
Cursor cursor=ctx.getContentResolver().query(uri, null, null, null, null);

   while (cursor.moveToNext()) { 
   String contactId = cursor.getString(cursor.getColumnIndex( 
     ContactsContract.Contacts._ID)); 
   String hasPhone = cursor.getString(cursor.getColumnIndex( 
     ContactsContract.Contacts.HAS_PHONE_NUMBER)); 
   if (Boolean.parseBoolean(hasPhone)) { 
                // You know have the number so now query it like this
Cursor phones = getContentResolver().query( 
  ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
  null, 
  ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, 
      null, null); 
    while (phones.moveToNext()) { 
     String phoneNumber = phones.getString( 
       phones.getColumnIndex( 
         ContactsContract.CommonDataKinds.Phone.NUMBER));                 
    } 
    phones.close(); 
   } 
 }

Is unless when you get all contact from phone and after that you test the result by one to one if has has number or not. You can set condition into query function.

Uri uri = data.getData();
Cursor cursor=ctx.getContentResolver().query(uri, null, ContactsContract.Contacts.HAS_PHONE_NUMBER + " = 1", null, null);

The rest of code will be the same without this test:

   String hasPhone = cursor.getString(cursor.getColumnIndex( 
     ContactsContract.Contacts.HAS_PHONE_NUMBER)); 
   if (Boolean.parseBoolean(hasPhone)) {
