@Override

ContentResolver resolver = context.getContentResolver();
Cursor cursor = null;// 光标
// 读取收件箱中指定号码的短信
cursor = resolver.query(Uri.parse("content://sms/"), new String[] {
"_id", "address", "body", "read" }, "address=?",
new String[] { "+86" + number }, "date desc");
if (cursor.getCount() == 0) {
cursor = resolver.query(Uri.parse("content://sms/"),
new String[] { "_id", "address", "body", "read" },
"address=?", new String[] { number }, "date desc");
}
if (cursor != null) {//这个手机号有短信 //去出短信中所有数字
// int count = cursor.getCount();
// cursor.moveToFirst();
if (cursor.moveToFirst()) {
String smsbody = cursor.getString(cursor
.getColumnIndex("body"));
String regEx = "[^0-9]";
Pattern p = Pattern.compile(regEx);
Matcher m = p.matcher(smsbody.toString());
smsContent = m.replaceAll("").trim().toString();
verifyText.setText(smsContent);
}
}
}
}
}

如果没有成功,打印一下 里面数据库里存的address .这里只判断了 正常手机号码, 和+86手机号码.小米手机已通过测试.

自动获取短信验证码,两种方式,

内容提供者:获取短信数据库,查询指定号码.(就是以上代码)

广播接收者, 广播接收者,接收收到短信广播,取出当前短信内容, 容易被其他三方软件和系统自带软件提前拦截到.

有的软件是在开机就启动服务,进行拦截. 谁先接收到 可以取消广播,自己的软件就接收不到了.
