想要從聯系人列表“ android”中選擇電話號碼

Question

我想從聯系人列表中選擇電話號碼，我編寫此代碼以選擇電話號碼，但這會引發異常

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            switch (requestCode) {
            case CONTACT_PICKER_RESULT:
                Bundle extras = data.getExtras();
                Set<String> keys = extras.keySet();
                Iterator<String> iterate = keys.iterator();
                while (iterate.hasNext()) {
                    String key = iterate.next();
                    Log.v("R", key + "[" + extras.get(key) + "]");
                }
                Uri result = data.getData();
                Cursor c = getContentResolver().query(result,null,null,null,null);
                try {
                    c.moveToFirst();
                    String name = c

                    phones.close();

                    if (contactNumbers.length > 1 ) {
                        AlertDialog.Builder builder = new AlertDialog.Builder(this);
                        builder.setTitle("Call Number");
                        builder.setItems(contactNumbers, new OnClickListener() {
                            public void onClick(DialogInterface dialog, int which) {
                                ContactActivity.roamNumber
                                        .setText(contactNumbers[which]);

                            }

                        builder.create().show();

                    } else {
                        ContactActivity.roamNumber

                }

                break;
            }

        } else {
            // gracefully handle failure
            Log.i("", "Warning: activity result not ok");
        }


    }

注意：當選擇任何Facebook聯系人為我提供號碼拋出異常時，我的手機與Facebook同步：

我解決問題使用此代碼：

Uri result = data.getData();

                Cursor c = getContentResolver().query(result, null, null, null,
                        null);
                Log.d("Row Count c", c.getCount() +"");
                Log.d("result", result +"");

                try {
                    c.moveToFirst();
                    String name = c
                            .getString(c
                                    .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                    Log.i("name", name);

                    String contactId = c.getString(c
                            .getColumnIndex(ContactsContract.Contacts._ID));
                    Log.i("Contact Id : ", contactId);
                    Cursor phoness = getContentResolver().query(
                            ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                            new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},
                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID
                                    + " = " + contactId, null, null);
                    Cursor phones = managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                            new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER}, 
                            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME  +

                        builder.create().show();

                    } else {

                        .setText(contactNumbers[0]);
                     }


                } finally {

                      }
