TextView的autoLink属性

最近看到一篇文章，讲了TextView的属性，今天我就讲讲它的autoLink属性
首先看效果图：
这里写图片描述

这种链接方式是如何实现的呢？
1.布局文件

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.mag.administrator.textviewdemo.MainActivity">    <TextView        android:id="@+id/text1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:autoLink="all"        android:text="@string/text_one" />    <TextView        android:id="@+id/text2"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@id/text1"        android:autoLink="all" /></RelativeLayout>

其中@string/text_one 所引用的

 <string name="text_one">        <b>text_auto_linkify: 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.    </string>

2.java代码中

public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        SpannableString ss = new SpannableString(                "text_spannable: Manually created spans. Click here to dial the phone:4155551212");        ss.setSpan(new StyleSpan(Typeface.BOLD), 0, 39,                Spanned.SPAN_INCLUSIVE_INCLUSIVE);        TextView textViewSpan = (TextView) findViewById(R.id.text2);        textViewSpan.setText(ss);        textViewSpan.setMovementMethod(LinkMovementMethod.getInstance());    }}

好了，分析下：布局文件中是设置了两段文字的，第一个TextView的实现方式就是使用了autoLink属性，然后在string.xml文件中写上所引用字符串就行了。 < b > 在html代码中是加粗的标签

第二个TextView也使用了autoLink属性，但是没有设置text，而是在Java代码中设置的，这样的使用场景可以是在动态加载，从网络中加载数据。
