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：
* @author ldm
* @date 2016-4-21 下午4:34:05
*/
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="&lt;b>text1: Various kinds
  of data that will be auto-linked.&lt;/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）。

希望本文所述对大家Android程序设计有所帮助。
