android - 如何检查用户在 EditText 中输入自己的电话号码？

Question

手机号码将由用户在我的 Android 应用程序的注册页面上的编辑文本中输入。我如何检查用户输入的是他/她的手机号码而不是其他人的？

我已经试过了:

TelephonyManager tMgr =(TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
  mPhoneNumber = tMgr.getLine1Number();

并将此变量与 edittext 的文本进行比较。但在我的例子中，mPhoneNumber 返回 NULL。还有其他选择吗？如何解决这个问题？

任何帮助都将不胜感激。

我试过这个:检查源代码:

     public class MainActivity extends Activity{    

    Button submit;
    EditText contact;
    String phNo;
    ProgressDialog progress;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        contact = (EditText)findViewById(R.id.mobileNumber);
        submit = (Button) findViewById(R.id.button1);

        submit.setOnClickListener(new OnClickListener()
        {
                public void onClick(View v)
                {
                    phNo = contact.getText().toString();
                    new CheckOwnMobileNumber().execute();
                    Toast.makeText(getApplicationContext(), phNo, Toast.LENGTH_LONG).show();
                }
        });



    }

    private class CheckOwnMobileNumber extends AsyncTask<String, Void, String>
    {
        @Override
        protected void onPostExecute(String result)
        {
            // TODO Auto-generated method stub
            if(progress.isShowing())
            {
                progress.dismiss();
                // Check SMS Received or not after that open dialog date
                /*if(SMSReceiver.str.equals(phNo))
                {
                    Toast.makeText(getApplicationContext(), "Thanks for providing your number.", Toast.LENGTH_LONG).show();
                }
                else
                {
                    Toast.makeText(getApplicationContext(), "Provide your own mobile number please.", Toast.LENGTH_LONG).show();
                    return;
                }*/

            }
        }

        @Override
        protected String doInBackground(String... params)
        {
            // TODO Auto-generated method stub
            String msg = phNo;
            try
            {
                sendSMS(phNo, msg);
            }
            catch(Exception ex)
            {
                Log.v("Exception :", ""+ex);
            }
            return null;
        }

        @Override
        protected void onPreExecute() {
            // TODO Auto-generated method stub
            progress = ProgressDialog.show(MainActivity.this, "","Checking Mobile Number...");
            progress.setIndeterminate(true);
            progress.getWindow().setLayout(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
            super.onPreExecute();
        }

}

    private void sendSMS(String phoneNumber, String message)
        {        
            //PendingIntent pi = PendingIntent.getActivity(getApplicationContext(), 0, new Intent(getApplicationContext(), MainActivity.class), 0);                
            SmsManager sms = SmsManager.getDefault();
            sms.sendTextMessage(phoneNumber, null, message, null, null);        
        }
}

接收者是否收听短信？

public class SMSReceiver extends BroadcastReceiver
{
private static final String ACTION_SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
Context mContext;
private Intent mIntent;
static String address, str = null;

// Retrieve SMS
public void onReceive(Context context, Intent intent) {
    mContext = context;
    mIntent = intent;

    String action = intent.getAction();

    if(action.equals(ACTION_SMS_RECEIVED))
    {
        SmsMessage[] msgs = getMessagesFromIntent(mIntent);
        if (msgs != null)
        {
            for (int i = 0; i < msgs.length; i++)
            {
                address = msgs[i].getOriginatingAddress();
                str = msgs[i].getMessageBody().toString();
            }
        }   

        // ---send a broadcast intent to update the SMS received in the
        // activity---
        Intent broadcastIntent = new Intent();
        broadcastIntent.setAction("SMS_RECEIVED_ACTION");
        broadcastIntent.putExtra("sms", str);
        context.sendBroadcast(broadcastIntent);
    }

}

public static SmsMessage[] getMessagesFromIntent(Intent intent)
{
    Object[] messages = (Object[]) intent.getSerializableExtra("pdus");
    byte[][] pduObjs = new byte[messages.length][];

    for (int i = 0; i < messages.length; i++)
    {
        pduObjs[i] = (byte[]) messages[i];
    }

    byte[][] pdus = new byte[pduObjs.length][];
    int pduCount = pdus.length;
    SmsMessage[] msgs = new SmsMessage[pduCount];
    for (int i = 0; i < pduCount; i++)
    {
        pdus[i] = pduObjs[i];
        msgs[i] = SmsMessage.createFromPdu(pdus[i]);
    }
    return msgs;
}
}

Answer 1

不能保证 tMgr.getLine1Number(); 将始终返回您的 SIM 卡号码。因为这取决于 SIM 卡中号码的可用性。就像我的情况一样，我的 Tre-Sweden SIM 卡不包含我的电话号码。

但是如果您将 SIM 卡放入旧的 SonyEricsson 或诺基亚手机中，那么您将可以选择编辑此号码(在 SIM 上)。完成后，Android 设备将识别该号码并显示给您。

此外，如果你确实是通过验证码获取到你的电话号码，那么比较两个号码的最佳方式是:

boolean isSame = PhoneNumberUtils.compare(num1, num2);

---

或者，您可以实现某种 PIN 码验证逻辑(例如 Viber、WhatsApp 或其他应用程序)，您可以在其中要求用户在注册期间输入他们的电话号码。稍后，该电话号码会被发送到服务器，并根据该号码生成一个 PIN 码，并通过 SMS 发送给用户。最后，用户必须输入该 PIN 码(通过短信收到)才能完成注册。

或者

只需从用户的设备(在征得同意的情况下)向您的服务器/设备发送一条短信，即可了解他们的电话号码。
