Android 富文本框实现 RichEditText
Android系统自带控件没有富文本框控件，如果想写一封带格式的邮件基本上不可能，EdtiText只有默认一种格式，显示不能滿足要求,！！正好项目需要研究了一下，开发了此控件，现将一些源代码开放一下，希望对有需要此功能开发者们能提供点帮助，见效果图：
做了五个常用输写功能，UI不太好看，没关系这些可以利用图片素材喧染一下，在这里注重的是功能实现哈！
实现功能：
1、选中文本实现粗体、斜体、下划线效果
2、选中文本实现字体颜色、大小效果
3、选中文本上述效果可以叠加
4、使用html标记实现，以邮件发送出去，对方在PC或手机上同样可以看到编辑效果
对于html标记实现，很容易想到利用 sdk包下有个Html类，可以操作它来生成html标记文本，这是对的，后边要把显示的效果变成html标记和显示全依赖于它，主要利用其这个方法 Html.fromHtml("<b>test</b>"); 此方法返回Spanned对象，设置给EditText，就可显示效果。
虽然有了上述思想但是解决不了我们的需求问题，首先我们不可能在每个选中的文本上都手动插入html标记进行显示，你想想看，假如用户同时在选中的文本加上粗体、斜体、颜色或者在已加上效果的文本上只选取部分文本添加下划线效果等此类种种复杂场合依次手动地靠记录选中文本开始位置和结束位置的索引来添加html标记显示对应的效果，那将是一件可怕的事情，可想而知程序在写在后边时，逻辑上肯定得把开发者自己绕晕，所以靠记录添加html标记的索引方式来实现效果是不可取的，我们得寻找简便方法，在oschina上，我发现有一个开源项目引导了我的开发思想，项目名是RichEditText : http://www.oschina.net/p/cwac-richedit, 可以下载下来运行看看，不过需要一些第三方库的支持，这里不细说了，好了，现在讲述一下它的实现。
通过查看开源代码，你会发现在sdk下，text.style 包里面包含了所有我们需要的样式，像粗体、斜体等等这类效果都对应封装了相关的类，我们只要操作类里实现的方法就可能轻轻松松给选中的文本添加html标记，像添加标记、移除标记、获得标记都有其对应的方法，不再详述，下面我介绍一下需要用到的几个类
AbsoluteSizeSpan 控制字体大小类， ForegroundColorSpan 控制字体颜色类，StyleSapn 控制字体样式类(精体、斜体、下划线等)，其中还有一个选中文本类 Selection，这是我们需要用到的几个类，弄清楚之后，我们就可以沿着这个思路来编码了，建立 StyleEffect .java 请看源码
import android.text.Spannable;
import android.text.style.StyleSpan; public class StyleEffect extends Effect<Boolean> {
private int style; StyleEffect(int style) {
this.style=style;
} @Override
boolean existsInSelection(MyEditText editor) {
Selection selection=new Selection(editor);
Spannable str=editor.getText();
boolean result=false; if (selection.start != selection.end) {
for (StyleSpan span : getStyleSpans(str, selection)) {
if (span.getStyle() == style) {
result=true;
break;
}
}
}
else {
StyleSpan[] spansBefore=
str.getSpans(selection.start - 1, selection.end,
StyleSpan.class);
StyleSpan[] spansAfter=
str.getSpans(selection.start, selection.end + 1,
StyleSpan.class); for (StyleSpan span : spansBefore) {
if (span.getStyle() == style) {
result=true;
break;
}
} if (result) {
result=false; for (StyleSpan span : spansAfter) {
if (span.getStyle() == style) {
result=true;
break;
}
}
}
} return(result);
} @Override
Boolean valueInSelection(MyEditText editor) {
return(existsInSelection(editor));
} @Override
void applyToSelection(MyEditText editor, Boolean add) {
applyToSpannable(editor.getText(), new Selection(editor), add);
} void applyToSpannable(Spannable str, Selection selection, Boolean add) {
int prologueStart=Integer.MAX_VALUE;
int epilogueEnd=-1; for (StyleSpan span : getStyleSpans(str, selection)) {
if (span.getStyle() == style) {
int spanStart=str.getSpanStart(span); if (spanStart < selection.start) {
prologueStart=Math.min(prologueStart, spanStart);
} int spanEnd=str.getSpanEnd(span); if (spanEnd > selection.end) {
epilogueEnd=Math.max(epilogueEnd, spanEnd);
} str.removeSpan(span);
}
} if (add) {
str.setSpan(new StyleSpan(style), selection.start, selection.end,
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}
else {
if (prologueStart < Integer.MAX_VALUE) {
str.setSpan(new StyleSpan(style), prologueStart,
selection.start, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
} if (epilogueEnd > -1) {
str.setSpan(new StyleSpan(style), selection.end, epilogueEnd,
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}
}
} private StyleSpan[] getStyleSpans(Spannable str, Selection selection) {
return(str.getSpans(selection.start, selection.end, StyleSpan.class));
}
}
existsInSelection 方法，检查选中文本的 EditText 是否已经存在字体效果
applyToSelection 方法，给选中的文本申请实现字体效果，得点在于
str.setSpan(new StyleSpan(style), selection.end, epilogueEnd,
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
str 选中的文本，new StyelSpan（style） 输入参数是所设置的字体效果，粗体: Typeface.BOLD 斜体：Typeface.ITALIC
调用方式:
public static final Effect<Boolean> BOLD = new StyleEffect(Typeface.BOLD);
public static final Effect<Boolean> ITALIC = new StyleEffect(Typeface.ITALIC);
public static final Effect<Boolean> UNDERLINE=new UnderlineEffect();
BOLD.applyToSelection(editText, !effect.valueInSelection(editText));
ITALIC.applyToSelection(editText, !effect.valueInSelection(editText));
UNDRLINE.applyToSelection(editText, !effect.valueInSelection(editText));
建立 AbsoluteSizeEffect.java 来控制字体大小 , 请看源码:
import android.text.Spannable;
import android.text.style.AbsoluteSizeSpan; public class AbsoluteSizeEffect extends Effect<Integer> {
@Override
boolean existsInSelection(MyEditText editor) {
Selection selection=new Selection(editor);
Spannable str=editor.getText(); return(getAbsoluteSizeSpans(str, selection).length > 0);
} @Override
Integer valueInSelection(MyEditText editor) {
Selection selection=new Selection(editor);
Spannable str=editor.getText();
int max=0;
AbsoluteSizeSpan[] spans=getAbsoluteSizeSpans(str, selection); if (spans.length > 0) {
for (AbsoluteSizeSpan span : spans) {
max=(max < span.getSize() ? span.getSize() : max);
} return(max);
} return(null);
} @Override
void applyToSelection(MyEditText editor, Integer proportion) {
Selection selection=new Selection(editor);
Spannable str=editor.getText(); for (AbsoluteSizeSpan span : getAbsoluteSizeSpans(str, selection)) {
str.removeSpan(span);
} if (proportion != null) {
str.setSpan(new AbsoluteSizeSpan(proportion), selection.start,
selection.end, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}
} private AbsoluteSizeSpan[] getAbsoluteSizeSpans(Spannable str,
Selection selection) {
return(str.getSpans(selection.start, selection.end,
AbsoluteSizeSpan.class));
}
代码思想与StyelEffect.java 一样，不再详述，调用方式：
public static final Effect<Integer> AbsoluteSize=new AbsoluteSizeEffect();
AbsoluteSize.applyToSelection(editText, progress);
建立 ForegroundColorEffect.java 控制字体效果，请看源码：
import android.text.Spannable;
import android.text.style.ForegroundColorSpan; public class ForegroundColorEffect extends Effect<Integer> {
@Override
boolean existsInSelection(MyEditText editor) {
Selection selection=new Selection(editor);
Spannable str=editor.getText(); return(getForegroundColorSpans(str, selection).length > 0);
} @Override
Integer valueInSelection(MyEditText editor) {
Selection selection=new Selection(editor);
Spannable str=editor.getText();
int max=0;
ForegroundColorSpan[] spans=getForegroundColorSpans(str, selection); if (spans.length > 0) {
for (ForegroundColorSpan span : spans) {
max=(max < span.getForegroundColor() ? span.getForegroundColor() : max);
} return(max);
} return(null);
} @Override
void applyToSelection(MyEditText editor, Integer proportion) {
Selection selection=new Selection(editor);
Spannable str=editor.getText(); for (ForegroundColorSpan span : getForegroundColorSpans(str, selection)) {
str.removeSpan(span);
} if (proportion != null) {
str.setSpan(new ForegroundColorSpan(proportion), selection.start,
selection.end, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}
} private ForegroundColorSpan[] getForegroundColorSpans(Spannable str,
Selection selection) {
return(str.getSpans(selection.start, selection.end,
ForegroundColorSpan.class));
}
调用方式：
public static final Effect<Integer> ForcegroundColor=new ForegroundColorEffect();
ForcegroundColor.applyToSelection(editText, color);
最后通过调用 Html.toHtml(editText.getText()) ; 可以获得设置的html标记字符串，然后发送出去，对方即可以看到相同效果。
在这里注意一下，如果文本框输入的是中文，调用toHtml方法得到字符将是html编码的字符串，需要解码，才能得到明文，我顺便也把解码类贴出来
HTMLDecoder.java ,源码：
import java.util.HashMap;
public class HTMLDecoder {

}
break;
}
}
}
}
} else if (isLetter(d)) {
