Android：如何检查 BroadcastReceiver 中的联系人 phone 中是否存在传入的 SMS 号码并且阻止号码不存在

Question

我想当有来信的号码不在联系人的短信时，然后块中的文本，通过检查是否有号码不在 phone 书中来确定。我有一个代码检查号码存在，但错误时间我代码移动 class BroadcastReceiver？，以及如何在 onReceive 中调用方法 contactExists？

 public boolean contactExists(Context context, String number, ContentResolver contentResolver) {
            Cursor phones = contentResolver.query(ContactsContract.CommonDataKinds.Phone.
                    CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
            while (phones.moveToNext()){
                String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                if(PhoneNumberUtils.compare(number, phoneNumber)){
                    return true;
                }
            }
            return false;
        }

我使用 AsyncTask，但我对调用方法 contactExists 感到困惑，以及如何将号码输入 contactExists，以便识别现有号码

public class SmsReceiver extends BroadcastReceiver {

    public static int MSG_TPE = 0;
    private String number;

    @Override

            if (bundle != null) {
                Object[] pdus = (Object[]) bundle.get("pdus");
                msgs = new SmsMessage[pdus.length];
                for (int i = 0; i < msgs.length; i++) {
                    msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                    number = msgs[i].getOriginatingAddress();
                    message += msgs[i].getMessageBody().toString();
                    message += "\n";

不要在主线程中查询内容提供程序，运行新线程或使用 AsyncTask。

private class Checkcontact extends AsyncTask<String, Void, Boolean> {

    private Context context;

    public Checkcontact(Context context) {
        // TODO Auto-generated constructor stub
        this.context = context;
    }

    @Override
    protected Boolean doInBackground(String... strings) {
        try {
            return contactExists(context, strings[0]);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return false;
    }

    // The argument result is return by method doInBackground
    @Override
    protected void onPostExecute(Boolean result) {
        // TODO Auto-generated method stub
        super.onPostExecute(result);

        // You can handle the result here
    }

    public boolean contactExists(Context context, String number) throws Exception {
        Uri lookupUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));

        String[] mPhoneNumberProjection = { ContactsContract.PhoneLookup._ID, ContactsContract.PhoneLookup.NUMBER,
                ContactsContract.PhoneLookup.DISPLAY_NAME };

        Cursor cur = context.getContentResolver().query(lookupUri, mPhoneNumberProjection, null, null, null);
        try {
            if (cur.moveToFirst()) {
                // if contact are in contact list it will return true
                return true;
            }
        } finally {
            if (cur != null)
                cur.close();
        }
        // if contact are not match that means contact are not added
        return false;
    }
}

开始任务：

new Checkcontact(context).execute("123456789");
