Android 访问收件箱消息

我想访问收件箱邮件。为此，我正在编写以下代码：

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

但我得到了以下错误：

如何解决此问题？

首先，您必须确认已在清单文件中添加了权限

以下权限适用于邮件

android.permission.RECEIVE_SMS

android.permission.SEND_SMS

如果是这样，那么您缺少一个条件，即如果您有多个联系人以及如何检索所有联系人的消息，那么您需要按照以下方式构建代码：

public List<Sms> getSms() {
    List<Sms> lstSms = new ArrayList<Sms>();
    Sms objSms = new Sms();
    Uri message = Uri.parse("content://sms/");
    ContentResolver cr = mActivity.getContentResolver();

    Cursor c = cr.query(message, null, null, null, null);
    mActivity.startManagingCursor(c);
    int totalSMS = c.getCount();

    if (c.moveToFirst()) {
        for (int i = 0; i < totalSMS; i++) {

            objSms = new Sms();
            objSms.setId(c.getString(c.getColumnIndexOrThrow("_id")));
            objSms.setAddress(c.getString(c
                    .getColumnIndexOrThrow("address")));
            objSms.setMsg(c.getString(c.getColumnIndexOrThrow("body")));
            objSms.setReadState(c.getString(c.getColumnIndex("read")));
            objSms.setTime(c.getString(c.getColumnIndexOrThrow("date")));
            if (c.getString(c.getColumnIndexOrThrow("type")).contains("1")) {
                objSms.setFolderName("inbox");
            } else {
                objSms.setFolderName("sent");
            }

            lstSms.add(objSms);
            c.moveToNext();
        }
    }
    // else {
    // throw new RuntimeException("You have no SMS");
    // }
    c.close();

    return lstSms;
}

公共列表getSms（）{
List lstSms=new ArrayList（）；
Sms objSms=新Sms（）；
Uri消息=Uri.parse（“content://sms/");
ContentResolver cr=mActivity.getContentResolver（）；
游标c=cr.query（消息，null，null，null，null）；
mActivity.startManagingCursor（c）；
int totalSMS=c.getCount（）；
if（c.moveToFirst（））{
对于（int i=0；i

更换此

  cur.moveToNext();

为此：

  cur.moveToFirst();

并将此权限设置为您的清单

  <uses-permission android:name="android.permission.READ_SMS" />

获取所有收件箱消息：

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();

body=新字符串[c.getCount（）]；
number=新字符串[c.getCount（）]；
if（c.moveToFirst（））{
对于（int i=0；我共享了logcat..plz chek.请正确缩进，我已经添加了答案.你能解释一下你做了什么吗？
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();
