textview的颜色

一、使用html

Spanned text = Html.fromHtml(source);
tv.setText(text);
例如：

import android.text.Html;
TextView textview= (TextView) findViewById(R.id.text3);
textview.setText(
Html.fromHtml(
"<b>text:</b>Text with a " +
"<a href=/"http://www.google.com/">link</a> " +
"created in the Java source code using HTML."));

二、借用spannable string

Activity代码：

1. packagecom.zhou.activity;
3. importandroid.app.Activity;
4. importandroid.graphics.Color;
5. importandroid.os.Bundle;
6. importandroid.text.Spannable;
7. importandroid.text.SpannableString;
8. importandroid.text.Spanned;
9. importandroid.text.method.LinkMovementMethod;
10. importandroid.text.style.BackgroundColorSpan;
11. importandroid.text.style.ForegroundColorSpan;
12. importandroid.text.style.StyleSpan;
13. importandroid.text.style.URLSpan;
14. importandroid.widget.TextView;
16. publicclassTextViewLinkActivityextendsActivity{
17. TextViewmyTextView;
18. @Override
19. publicvoidonCreate(BundlesavedInstanceState){
20. super.onCreate(savedInstanceState);
21. setContentView(R.layout.main);
22. myTextView=(TextView)this.findViewById(R.id.myTextView);
24. //创建一个SpannableString对象
25. SpannableStringsp=newSpannableString("这句话中有百度超链接,有高亮显示，这样，或者这样，还有斜体.");
26. //设置超链接
27. sp.setSpan(newURLSpan("http://www.baidu.com"),5,7,
28. Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
29. //设置高亮样式一
30. sp.setSpan(newBackgroundColorSpan(Color.RED),17,19,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
31. //设置高亮样式二
32. sp.setSpan(newForegroundColorSpan(Color.YELLOW),20,24,Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
33. //设置斜体
34. sp.setSpan(newStyleSpan(android.graphics.Typeface.BOLD_ITALIC),27,29,Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
35. //SpannableString对象设置给TextView
36. myTextView.setText(sp);
37. //设置TextView可点击
38. myTextView.setMovementMethod(LinkMovementMethod.getInstance());
39. }
40. }
