我正在尝试通过启动打开联系人选择器的意图来访问电话号码。一切都很好，直到我尝试制作光标。我可以获取联系人的 ID，但在光标初始化的那一行，应用程序停止工作。

编码 ：

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        Uri result = null ;
        switch (requestCode) {
        case 1001:
            Bundle extras = data.getExtras();
            Set<String> keys = extras.keySet();
            Iterator<String> iterate = keys.iterator();
            while (iterate.hasNext()) {
                String key = iterate.next();
                l(key + "[" + extras.get(key) + "]");
            }
            result = data.getData();
            l( "Got a result: "+ result.toString());

            break;
        }
            String id = result.getLastPathSegment();  
            l("key:" + id) ; 
//Line with the problems  , here the app stops


            Cursor cur = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, new String[]{id}, null);

            if(cur.getCount() > 0) {
                while (cur.moveToNext()) {
                    String idst = cur.getString(
                                cur.getColumnIndex(ContactsContract.Contacts._ID));
                String name = cur.getString(
                                cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                    //Query phone here.  Covered next
                    }
                    }
            }
    } else {

        l( "A problem occured");
    }
}

}

错误 ：

只需使用

cur.moveToFirst()

在while循环之前。
