android4.4通话记录修改

修改android 4.4通话记录显示方式，使其相同的号码不再出现原生代码如下 com.android.dialer.calllog.CallLogGroupBuilder
public void addGroups(Cursor cursor) {        final int count = cursor.getCount();
        if (count == 0) {
            return;
        }

        int currentGroupSize = 1;
        cursor.moveToFirst();
        // The number of the first entry in the group.
        String firstNumber = cursor.getString(CallLogQuery.NUMBER);
        // This is the type of the first call in the group.
        int firstCallType = cursor.getInt(CallLogQuery.CALL_TYPE);
        while (cursor.moveToNext()) {
            // The number of the current row in the cursor.
            final String currentNumber = cursor.getString(CallLogQuery.NUMBER);
            final int callType = cursor.getInt(CallLogQuery.CALL_TYPE);
            final boolean sameNumber = equalNumbers(firstNumber, currentNumber);
            final boolean shouldGroup;

            if (!sameNumber) {
                // Should only group with calls from the same number.
                shouldGroup = false;
            } else if (firstCallType == Calls.VOICEMAIL_TYPE) {
                // never group voicemail.
                shouldGroup = false;
            } else {
                // Incoming, outgoing, and missed calls group together.
                shouldGroup = callType != Calls.VOICEMAIL_TYPE;
            }

            if (shouldGroup) {
                // Increment the size of the group to include the current call, but do not create
                // the group until we find a call that does not match.
                currentGroupSize++;
            } else {
                // Create a group for the previous set of calls, excluding the current one, but do
                // not create a group for a single call.
                if (currentGroupSize > 1) {
                    addGroup(cursor.getPosition() - currentGroupSize, currentGroupSize);
                }
                // Start a new group; it will include at least the current call.
                currentGroupSize = 1;
                // The current entry is now the first in the group.
                firstNumber = currentNumber;
                firstCallType = callType;
            }
        }
        // If the last set of calls at the end of the call log was itself a group, create it now.
        if (currentGroupSize > 1) {
            addGroup(count - currentGroupSize, currentGroupSize);
        }
    }


修改后如下
public void addGroups(Cursor cursor) {
        final int count = cursor.getCount();
        if (count == 0) {
            return;
        }
        int currentGroupSize = 1;
        cursor.moveToFirst();

        String firstNumber = cursor.getString(CallLogQuery.NUMBER);
  ArrayList previousNumbers = new ArrayList();
  previousNumbers.add(firstNumber);

        while (cursor.moveToNext()) {
            final String currentNumber = cursor.getString(CallLogQuery.NUMBER);
   final boolean isNewNumber = !previousNumbers.contains(currentNumber);
   if(isNewNumber){
    previousNumbers.add(currentNumber);
   }

   if(isNewNumber){
       if (currentGroupSize > 1) {
                    addGroup(cursor.getPosition() - currentGroupSize, currentGroupSize);
                }
                currentGroupSize = 1;
   }else{
       currentGroupSize++;
   }
        }

        if (currentGroupSize > 1) {
            addGroup(count - currentGroupSize, currentGroupSize);
        }
    }
