访问收件箱的信息报错

我想访问收件箱信息,写了如下代码:

Uri uriSMSURI = Uri.parse("content://sms/inbox");
    Cursor cur = getContentResolver().query(uriSMSURI, null, null, null,null);
    String sms = "";
    cur.moveToNext();
    sms = cur.getString(0);

然后报出如下错误:

已采纳
Uri uri = Uri.parse("content://sms/inbox");
Cursor c= getContentResolver().query(uri, null, null ,null,null);
startManagingCursor(c);

得到全部信箱信息:

body = new String[c.getCount()];
number = new String[c.getCount()];

if(c.moveToFirst()){
        for(int i=0;i<c.getCount();i++){
                body[i]= c.getString(c.getColumnIndexOrThrow("body")).toString();
                number[i]=c.getString(c.getColumnIndexOrThrow("address")).toString();
                c.moveToNext();
       }
   }
   c.close();

你的cursor里面有数据? 都数组越界了啊,保护工作没做好呀。
