Android TextView實現帶連結文字事件監聽的三種常用方式示例

NO IMAGE

本文例項講述了Android TextView實現帶連結文字事件監聽的三種常用方式。分享給大家供大家參考,具體如下:


/**
* TextView實現文字連結跳轉功能

*/
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();
}
/**
* 通過不同方式實現TextView中文字點選連結跳轉功能

*/
private void setTextViewLink() {
// 以Html格式href連結方式實現跳轉
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());
// 通過SpannableString的setMovementMethod方法實現連結效果
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());
}
}

佈局檔案


<?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" >
<!-- 通過在佈局中autoLink屬性設定TextView的連結功能. -->
<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
[email protected] for an e-mail link. If you have a URI like
http://www.example.com/lala/[email protected] 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, [email protected],
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>

其中通過在而已程式碼中android:autoLink屬性的選專案有:none(無連結效果),web(網頁連結),email(發郵件),phone(打電話),map(定位)及all(預設全都自動連結)。
