Android中TextView实现部分文字可点击跳转

本文实例为大家分享了textview部分文字可点击跳转的具体代码，供大家参考，具体内容如下

效果图：

需求：每个item的文字都有两部分是连接可点击

当然需要用到spannablestring和clickablespan。

import android.text.textpaint;
import android.text.style.clickablespan;
import android.view.view;

import com.xuehu365.xuehu.app;
import com.xuehu365.xuehu.r;

/**

 */
public class recordclickspan extends clickablespan {
 @override
 public void onclick(view widget) {

 }

 @override
 public void updatedrawstate(textpaint ds) {
  ds.setcolor(app.getapplication().getresources().getcolor(r.color.c0066cc));
  ds.setunderlinetext(false);
 }
}

private void getrecordcontent(baseviewholder holder, final studylogmodel logmodel) {
 textview record = holder.getview(r.id.record);
 string coursename = !textutils.isempty(logmodel.getcoursetitle()) ? "《" + logmodel.getcoursetitle() + "》" : "";
 string lessonname = "：《" + (!textutils.isempty(logmodel.getsourcetitle()) ? logmodel.getsourcetitle() + "》" : logmodel.getlessontitle() + "》");
 spannablestring coursespannable = new spannablestring(coursename);
 spannablestring lessonspannable = new spannablestring(lessonname);
 recordclickspan coursespan = new recordclickspan() {
  @override
  public void onclick(view widget) {
   urlbus.dourl("http://www.baidu.com", "", context);
  }
 };
 recordclickspan lessonspan = new recordclickspan() {
  @override
  public void onclick(view widget) {
   urlbus.dourl("http://www.taobao.com", "", context);
  }
 };
 coursespannable.setspan(coursespan, 0, coursename.length(), spanned.span_inclusive_exclusive);
 lessonspannable.setspan(lessonspan, 0, lessonname.length(), spanned.span_inclusive_exclusive);
 switch (integer.parseint(logmodel.getsourcetype())) {
  case courseplanadapter.video_live:
  case courseplanadapter.video_recode:
   record.append("观看");
   record.append(coursespannable);
   record.append("的视频");
   record.append(lessonspannable);
   break;
  case courseplanadapter.voice_live:
  case courseplanadapter.voice_recode:
   record.append("收听");
   record.append(coursespannable);
   record.append("的语音");
   record.append(lessonspannable);
   break;
  case courseplanadapter.teach_face:
   record.append("在");
   record.append(coursespannable);
   record.append("的面授课时");
   record.append(lessonspannable);
   record.append("签到成功");
   break;
  case courseplanadapter.survey:
   record.append("完成");
   record.append(coursespannable);
   record.append("的调研");
   record.append(lessonspannable);
   break;
  case courseplanadapter.exam:
   record.append("完成");
   record.append(coursespannable);
   record.append("的考试");
   record.append(lessonspannable);
   break;
  case courseplanadapter.work:
   record.append("完成");
   record.append(coursespannable);
   record.append("的作业");
   record.append(lessonspannable);
   break;
  case courseplanadapter.article:
   record.append("阅读");
   record.append(coursespannable);
   record.append("的文章");
   record.append(lessonspannable);
   break;
  case courseplanadapter.file:
   record.append("下载");
   record.append(coursespannable);
   record.append("的文档");
   record.append(lessonspannable);
   break;
  default:
   record.append("完成");
   record.append(coursespannable);
   record.append("的");
   record.append(lessonspannable);
   break;
 }
 record.setmovementmethod(linkmovementmethod.getinstance());
}

注意：

1.继承clickablespan用来改链接颜色和去掉下划线

2.文字的每个部分的链接都要单独生成一个spannablestring和clickablespan，然后对应的setspan

3.特别特别要注意的是！textview最后append的时候一定要分别进行，不能一起append，这个坑花了我好些时间

比如：

-----------错误
record.append("观看"+coursespannable+"的视频"+lessonspannable);

-----------正确
record.append("观看");
record.append(coursespannable);
record.append("的视频");
record.append(lessonspannable);
