本文实例讲述了android textview实现带链接文字事件监听的三种常用方式。分享给大家供大家参考,具体如下:

/**
 * textview实现文字链接跳转功能

 */
public class textviewlinkact extends activity {
  private textview tv_3;
  private textview tv_4;
  @override
  protected void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
    setcontentview(r.layout.link);
    settextviewlink();
  }
  /**
   * 通过不同方式实现textview中文字点击链接跳转功能
   *

   */
  private void settextviewlink() {
    // 以html格式href链接方式实现跳转
    tv_3 = (textview) findviewbyid(r.id.text3);
    tv_3.settext(html
        .fromhtml("<b>text3: constructed from html programmatically.</b> text with a "
            + "<a href=\"http://www.google.com\">link</a> "
            + "created in the java source code using html."));
    tv_3.setmovementmethod(linkmovementmethod.getinstance());
    // 通过spannablestring的setmovementmethod方法实现链接效果
    spannablestring ss = new spannablestring(
        "text4: manually created spans. click here to dial the phone.");
    ss.setspan(new stylespan(typeface.bold), 0, 30,
        spanned.span_exclusive_exclusive);
    ss.setspan(new urlspan("tel:4155551212"), 31 + 6, 31 + 10,
        spanned.span_exclusive_exclusive);
    tv_4 = (textview) findviewbyid(r.id.text4);
    tv_4.settext(ss);
    tv_4.setmovementmethod(linkmovementmethod.getinstance());
  }
}

布局文件

<?xml version="1.0" encoding="utf-8"?>
<scrollview xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="wrap_content" >
  <linearlayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:divider="?android:attr/listdivider"
    android:orientation="vertical"
    android:showdividers="middle" >
    <!-- 通过在布局中autolink属性设置textview的链接功能. -->
    <textview
      android:id="@+id/text1"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:autolink="all"
      android:paddingbottom="8dp"
      android:text="<b>text1: various kinds
   of data that will be auto-linked.</b> in
   this text are some things that are actionable. for instance,
   you can click on http://www.google.com and it will launch the
   web browser. you can click on google.com too. if you
   click on (415) 555-1212 it should dial the phone. or just write
   foobar@example.com for an e-mail link. if you have a uri like
   http://www.example.com/lala/foobar@example.com you should get the
   full link not the e-mail address. or you can put a location
   like 1600 amphitheatre parkway, mountain view, ca 94043. to summarize:
   https://www.google.com, or 650-253-0000, somebody@example.com,
   or 9606 north mopac expressway, suite 400, austin, tx 78759."
      android:textappearance="?android:attr/textappearancemedium" />
    <textview
      android:id="@+id/text3"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:paddingbottom="8dp"
      android:paddingtop="8dp"
      android:textappearance="?android:attr/textappearancemedium" />
    <textview
      android:id="@+id/text4"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:paddingtop="8dp"
      android:textappearance="?android:attr/textappearancemedium" />
  </linearlayout>
</scrollview>

其中通过在而已代码中android:autolink属性的选项目有:none(无链接效果),web(网页链接),email(发邮件),phone(打电话),map(定位)及all(默认全都自动链接)。
