textView文本不同颜色

// 文本样式   
        EditText et = (EditText) findViewById(R.id.tv);   
        et.setText("Styling the content of an editText dynamically");   
        Spannable sp = et.getText();   
        sp.setSpan(new BackgroundColorSpan(Color.RED), 3, 8,   
                Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);   ／／３代表从第几个字符开始变颜色，注意第一个字符序号是０．
／／８代表变色到第几个字符．

        sp.setSpan(new StyleSpan(android.graphics.Typeface.BOLD_ITALIC), 0, 7,   
                Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);  
       textview.setText(sp);　　

java程序中动态改变TextView特定内容的Style或者实现更为复杂的效果，下边将使用Spannable介绍具体的实现方法，请参照以下代码设置：
01.// Get our EditText object.
02.EditText vw = (EditText)findViewById(R.id.text);
03.

04.// Set the EditText's text.
05.vw.setText("Italic, highlighted, bold.");
06.

07.// If this were just a TextView, we could do:
08.// vw.setText("Italic, highlighted, bold.", TextView.BufferType.SPANNABLE);
09.// to force it to use Spannable storage so styles can be attached.
10.// Or we could specify that in the XML.
11.

12.// Get the EditText's internal text storage
13.Spannable str = vw.getText();
14.

15.// Create our span sections, and assign a format to each.
16.str.setSpan(new StyleSpan(android.graphics.Typeface.ITALIC), 0, 7, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
17.str.setSpan(new BackgroundColorSpan(0xFFFFFF00), 8, 19, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
18.str.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), 21, str.length() - 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

和大家分享一下：
TextView tv;
tv.setText("Test");
Spannable span = (Spannable)tv.getText();
spn.setSpan(new BackgroundColor(#ffffffff), start, end,   Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
ps：start和end表示你要高亮显示的子串在Test中的起始和结束位置。

忘了一项，setText的时候要用setText("Text", TextView.BufferType.SPANNABLE);
