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="<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)。
