Optimize the code

[lbx2015]

change the method addIconFontDescriptor in Iconify.java to the following and used directly:

/**
 * Add support for a new icon font.
 *
 * @param iconFontDescriptorArray The IconDescriptors holding the ttf file reference and their mappings.
 */
public static void addIconFontDescriptors(IconFontDescriptor... iconFontDescriptorArray) {

    if (iconFontDescriptorArray != null && iconFontDescriptorArray.length > 0) {
        for (IconFontDescriptor iconFontDescriptor : iconFontDescriptorArray) {
            // Prevent duplicates
            for (IconFontDescriptorWrapper wrapper : iconFontDescriptors) {
                if (wrapper.getIconFontDescriptor().ttfFileName()
                        .equals(iconFontDescriptor.ttfFileName())) {
                    break;
                }
            }

            // Add to the list
            iconFontDescriptors.add(new IconFontDescriptorWrapper(iconFontDescriptor));
        }
    }
}

and using like this will be better, I delete the unnecessary class IconifyInitializer
now using like following which I think better:
Iconify.addIconFontDescriptors(
new FontAwesomeModule(),
new EntypoModule(),
new MaterialModule(),
new MaterialCommunityModule());

I also change another place in ParsingUtil to following, and I create the TypefaceSpanCache.java

text.setSpan(TypefaceSpanCache.getFaceSpan(icon,
iconFontDescriptor.getTypeface(context),
iconSizePx, iconSizeRatio, iconColor, spin, baselineAligned),
startIndex, startIndex + 1,
Spanned.SPAN_INCLUSIVE_EXCLUSIVE);

This can prevent many duplicate new CustomTypefaceSpan instance, as I debug when I screen down the screen it will duplicatedly new CustomTypefaceSpan, It's better to store faceSpan in memery.

package com.joanzapata.iconify.internal;

import android.graphics.Typeface;

import com.joanzapata.iconify.Icon;

import java.util.HashMap;

/**

• Created by zhangziwei on 1/7/16.

• This class is used to store the same icon TypefaceSpanCache instance in memory,

• otherwise the instance will be renew many times when we scroll the screen
  */
  public class TypefaceSpanCache {

  private static HashMap<String, CustomTypefaceSpan> faceSpans = new HashMap<String, CustomTypefaceSpan>();

  public static CustomTypefaceSpan getFaceSpan(Icon icon, Typeface type,
  float iconSizePx, float iconSizeRatio, int iconColor,
  boolean rotate, boolean baselineAligned) {

  String key = icon.key() + type.hashCode() + iconSizePx + iconSizeRatio + iconColor + rotate + baselineAligned;
  
  CustomTypefaceSpan customTypefaceSpan = faceSpans.get(key);
  
  if (customTypefaceSpan == null) {
      customTypefaceSpan = new CustomTypefaceSpan(icon,type,iconSizePx, iconSizeRatio, iconColor, rotate, baselineAligned);
      faceSpans.put(key, customTypefaceSpan);
  }
  
  return customTypefaceSpan;
  

  }
  }
