Question

I m new to Android. I m developing an app which blocks unwanted calls. Now I m stuck here when I try to compare the incoming number with the numbers in contact. Here is the code. Please help. Here while checking a Checkbox I need to block all calls from strangers (not in the contact)

Bundle extra=intent.getExtras();//new
telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
if(extra!=null)//new=== getting the blocked number {
    state=extra.getString(telephonyManager.EXTRA_STATE);
    if(state.equals(telephonyManager.EXTRA_STATE_RINGING)) {
        number=extra.getString(telephonyManager.EXTRA_INCOMING_NUMBER);
        Log.w("INCOMMING NUMBER",number);
    }
}
if(noStrangers_cb.isChecked()){
    Cursor phones1 = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
    while (phones1.moveToNext()){
        String phoneNumber = phones1.getString(phones1.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
        Log.d("NUMBER IN CONTACT",phoneNumber );

        //boolean val= number== phoneNumber;
        //String no=number;
        //Log.d("ASSIGNING NUMBER TO NO = ", no);
        //Collator c=Collator.getInstance();
        if(!phoneNumber.equals(number))
            {
            Log.d("IF ", "STRANGERS"+number);
            //Log.d("NUMBER CHECKING", "NUMBER = "+number+"CONTACT = "+phoneNumber);
            try {
                telephonyService.endCall();
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            }
    }
    phones1.close();
}//end if Strangers

LOGCAT: enter image description here

最新代码如下:

if(allContacts_cb.isChecked())
                     {
                      Log.d("BLOCK ALL CONTACTS","blocking contacts.........." );
                      Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
                       while (phones.moveToNext())
                       {
                        String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        Log.d("NUMBER IN CONTACT ",phoneNumber );
                        String num=phoneNumber.replace("-","");
                        String incom=incomingNumber;
                        String s1="0"+num;
                        String s2="+91"+num;
if((num.equals(incomingNumber))||((s1).equals(incomingNumber))||(s2).equals(incomingNumber))//if(phoneNumber.compareTo(no)==0)//&&(checking==true))
                        { 
                          Log.d("IF ", "INSIDE IF OF BLOCKING CONTACTS");//+cn+"num"+n);
                          Log.d("NUMBER CHECKING", "NUMBER = "+number+"CONTACT = "+phoneNumber);
                          try {
                            ending1=telephonyService.endCall();
                            if(ending1)
                             {  
                             for(int i=1;i<=1;i++)
                             {
                              android.telephony.SmsManager sms = android.telephony.SmsManager.getDefault();
                              sms.sendTextMessage(incom, null, SMS, null, null);
                              break;
                             }
                              }
                              } catch (Exception e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();
                                }

                          } 
                        else
                        {
                            if(noStrangers_cb.isChecked())
                            {
                                try {
                                    telephonyService.endCall();
                                } catch (RemoteException e) {
                                    // TODO Auto-generated catch block
                                    e.printStackTrace();
                                }
                            }
                        }
                          }//end of while
                          phones.close();
                         }//end if allContacts

任何人都可以帮助我.. 求你了..

从您的号码中替换字符不是最后的解决办法。您应该读到 < a href=" http:// developmenter. android. com/ reference/ android/ telephony/ Phone NumberUtils. html" rel= “ nofol” > Phone InnumberUtils , 或者这里是 < a href=> http://code.google. com/ p/libone序号/" rel="nofollown" > 图书馆最好的libphone序号 , 可用于与电话号码有关的各种操作。

阅读详情,“http://code.google.com/p/libianphonenumber/"rel=“no follow”关于libphonenumber 。

下面是代码剪切,可以用于你的目的。

public boolean isCallerInDatabase(String caller, String phoneNumberFromDb) {
        phoneUtil = PhoneNumberUtil.getInstance();
        if(phoneUtil.isNumberMatch(caller, phoneNumberFromDb) != PhoneNumberUtil.MatchType.NO_MATCH) {
            //Number matched 
            Log.i("TEST", "NUMBER MATCHED");
            return true;
        }
        Log.i("TEST", "NUMBER NOT MATCHED");
        return false;       
    }

更新: Android 添加该库为实用类。

Android 本身已被添加到 andref="http:// developtrader.android.com/ reference/android/croid/telephony/PhoneNemberUtils.html" rel="nofollow" >PhoneNemberUtils 类,用于电话相关辅助器的方法。要比较两个电话号码,您应该使用 < a href=""http://developtrader.android.android.com/android/telephony/PhoneNationUtils.html#compare%28java.lang.String,%20java.lang.string%29" rel="nofolpol>>Phone InternUtils.compare 方法。

快乐编码 :)

您可以在您的电话号码中将字符串“ -” 替换为“ ”, 然后用该字符串比较。

string no= Phonecontactno.StringReplace("-","");

现在使用此字符串来比较输入的否。

尝试以下条件也许对您有帮助

if(!(phoneNumber.toString().equals(number.toString)))
