我想问问，如何实现Android textview的部分字体变色并且整个段落左右对齐，你们有没有类似的demo？我搞了好几天都没实现，现在参照网上的代码，实现了段落对齐，然后分开使用Android HTML解析实现了部分文字变色，但是最后把它们两融在一起的时候，颜色就失效了，这个怎么破？
代码如下
= ;;TextPaint ;String = ;Pattern ;Matcher ;String[] = String[];String[] = String[];JustifyTextView(Context context) { (context); init();}JustifyTextView(Context context, AttributeSet attrs) { (context, attrs); init();}JustifyTextView(Context context, AttributeSet attrs, defStyleAttr) { (context, attrs, defStyleAttr); init();}init() { = getPaint(); .setColor(getCurrentTextColor()); .= getDrawableState();}onDraw(Canvas canvas) { = ; = getMeasuredWidth();+= getTextSize(); String text = getText().toString(); Layout layout = getLayout(); lineCount = layout.getLineCount(); (i = ; i < lineCount; i++) {lineStart = layout.getLineStart(i); lineEnd = layout.getLineEnd(i); String lineText = text.substring(lineStart, lineEnd);(needScale(lineText)) { (i == lineCount - ) {(lineText.indexOf() != -||lineText.indexOf() != -) .setColor(Color.); .setColor(Color.); canvas.drawText(lineText, , , ); } { (lineText.indexOf() != -||lineText.indexOf() != -) .setColor(Color.); .setColor(Color.); width = StaticLayout.(text, lineStart, lineEnd, ); drawScaleText(canvas, lineText, width); } } { canvas.drawText(lineText, , , ); } += getLineHeight();}}drawScaleText(Canvas canvas, String lineText, lineWidth) { x = ; (isFirstLineOfParagraph(lineText)) { String blanks = ; canvas.drawText(blanks, x, , ); width = StaticLayout.(blanks, ); x += width; lineText = lineText.substring(); } interval = (- lineWidth) / (lineText.length() - ); (i = ; i < lineText.length(); i++) { String character = String.(lineText.charAt(i)); cw = StaticLayout.(character, ); canvas.drawText(character, x, , ); x += (cw + interval); }}isFirstLineOfParagraph(String lineText) { lineText.length() > && lineText.charAt() == && lineText.charAt() == ;}needScale(String lineText) { (lineText.length() == ) { ; } { lineText.charAt(lineText.length() - ) != ; }}//使用正则表达式提取关键字setText(CharSequence text, BufferType type) { = Pattern.(); = .matcher(text); String s = text.toString(); (i = ; .find(); i++) { = .group().replaceAll(, ); s = s.replaceAll(, ).replace(, ); } text =text.toString().replaceAll(, ); .setText(text, type);} |
