Android TextView实现带链接文字事件监听的三种常用方式示例

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
 * @description：

 */
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
   *
   * @description：
   * @author ldm
   * @date 2016-4-21 下午4:24:13
   */
  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）。
