给textview加链接（4种方式）

使用android:autoLink属性

<TextView            android:id="@+id/text1"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:autoLink="all"            android:paddingBottom="8dp"            android:text="@string/link_text_auto"            android:textAppearance="?android:attr/textAppearanceMedium" />

字符串中的URL与phonenumber等会自动链接到

通过在字符串资源文件中加标记，这样链接就会出现，为了激活链接，需要调用textview的setMovementMethod()方法

<TextView            android:id="@+id/text2"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:paddingBottom="8dp"            android:paddingTop="8dp"            android:text="@string/link_text_manual"            android:textAppearance="?android:attr/textAppearanceMedium" /><string name="link_text_manual"><b>text2: Explicit links using &lt;a&gt; markup.</b>This has markup for a <a href="http://www.google.com">link</a> specified      via an &lt;a&gt; tag.  Use a \"tel:\" URL      to <a href="tel:4155551212">dial a phone number</a>.</string>    TextView t2 = (TextView) findViewById(R.id.text2);t2.setMovementMethod(LinkMovementMethod.getInstance());

通过代码添加链接

TextView t3 = (TextView) findViewById(R.id.text3);t3.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."));t3.setMovementMethod(LinkMovementMethod.getInstance());

不使用HTML进行编码

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);TextView t4 = (TextView) findViewById(R.id.text4);t4.setText(ss);t4.setMovementMethod(LinkMovementMethod.getInstance());
