  1. SpannableStringBuilderbuilder=newSpannableStringBuilder();
    2.             
    3.             
  3. Stringred="thisisred";
    4.             
  4. SpannableStringredSpannable=newSpannableString(red);
    5.             
  5. redSpannable.setSpan(newForegroundColorSpan(Color.RED),0,red.length(),0);
    6.             
  6. builder.append(redSpannable);
    7.             
    8.             
  8. Stringwhite="thisiswhite";
    9.             
  9. SpannableStringwhiteSpannable=newSpannableString(white);
    10.             
  10. whiteSpannable.setSpan(newForegroundColorSpan(Color.WHITE),0,white.length(),0);
    11.             
  11. builder.append(whiteSpannable);
    12.             
    13.             
  13. Stringblue="thisisblue";
    14.             
  14. SpannableStringblueSpannable=newSpannableString(blue);
    15.             
  15. blueSpannable.setSpan(newForegroundColorSpan(Color.BLUE),0,blue.length(),0);
    16.             
  16. builder.append(blueSpannable);
    17.             
    18.             
  18. mTextView.setText(builder,BufferType.SPANNABLE);
    19.

or

        
                
  1. yourTextView.setText(Html.fromHtml("<FONTCOLOR=\"#80776b\">Firstcolor</Font>"+"<FONTCOLOR=\"#80776b\">Secondcolor</Font>"));
    2.

or

        
                
  1. Stringtext="Thistextiswhite.<fontcolor=\"blue\">Thistextisblue.</font>";
    2.             
  2. textView.setText(Html.fromHtml(text),BufferType.SPANNABLE);
    3.

还有人封装了一下API:

I created a class like this:

        
                
  1. importandroid.text.SpannableStringBuilder;
    2.             
  2. importandroid.text.style.CharacterStyle;
    3.             
    4.             
  4. publicclassStyleableSpannableStringBuilderextendsSpannableStringBuilder{
    5.             
  5. publicStyleableSpannableStringBuilderappendWithStyle(CharacterStylec,CharSequencetext){
    6.             
  6. super.append(text);
    7.             
  7. intstartPos=length()-text.length();
    8.             
  8. setSpan(c,startPos,length(),0);
    9.             
  9. returnthis;
    10.             
  10. }
    11.             
    12.             
  12. publicStyleableSpannableStringBuilderappendWithStyle(CharacterStyle[]c,CharSequencetext){
    13.             
  13. super.append(text);
    14.             
  14. intstartPos=length()-text.length();
    15.             
  15. for(CharacterStylec1:c)
    16.             
  16. setSpan(c1,startPos,length(),0);
    17.             
  17. returnthis;
    18.             
  18. }
    19.             
  19. }
    20.

This allows me to do things like this:

        
                
  1. privatevoidbuildTickerItem(DelayedQuoteServiceObjecto)
    2.             
  2. {
    3.             
  3. DoublelastPrice=Double.parseDouble(o.getValue("LastPrice"));
    4.             
  4. DoubledayChange=Double.parseDouble(o.getValue("DayChange"));
    5.             
  5. DoublepercentChange=Double.parseDouble(o.getValue("PercentDayChange"))/100;
    6.             
    7.             
  7. if(o.isIndex()==true)
    8.             
  8. {
    9.             
    10.             
  10. tickerTapeData.appendWithStyle(newStyleSpan(Typeface.BOLD),o.getDisplayName());
    11.             
  11. tickerTapeData.append(""+indexFormat.format(lastPrice)+"(");
    12.             
    13.             
  13. if(dayChange>=0)
    14.             
  14. tickerTapeData.appendWithStyle(newForegroundColorSpan(Colours.getTickerPositive()),indexFormat.format(dayChange));
    15.             
  15. else
    16.             
  16. tickerTapeData.appendWithStyle(newForegroundColorSpan(Color.RED),indexFormat.format(dayChange));
    17.             
  17. }
    18.             
  18. else
    19.             
  19. {
    20.             
  20. tickerTapeData.appendWithStyle(newStyleSpan(Typeface.BOLD),o.ticker);
    21.             
    22.             
  22. tickerTapeData.append("@"+dollarFormat.format(lastPrice)+"(");
    23.             
    24.             
  24. if(dayChange>=0)
    25.             
  25. tickerTapeData.appendWithStyle(newForegroundColorSpan(Colours.getTickerPositive()),dollarFormat.format(dayChange));
    26.             
  26. else
    27.             
  27. tickerTapeData.appendWithStyle(newForegroundColorSpan(Color.RED),dollarFormat.format(dayChange));
    28.             
    29.             
    30.             
  30. }
    31.             
    32.             
  32. tickerTapeData.append("/");
    33.             
    34.             
    35.             
  35. if(dayChange>=0)
    36.             
  36. tickerTapeData.appendWithStyle(newForegroundColorSpan(Colours.getTickerPositive()),percentFormat.format(percentChange));
    37.             
  37. else
    38.             
  38. tickerTapeData.appendWithStyle(newForegroundColorSpan(Color.RED),percentFormat.format(percentChange));
    39.             
    40.             
  40. tickerTapeData.append(")");
    41.             
  41. }
    42.
