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);
