Android:html在strings.xml中
我想显示例如这个HTML代码:
<body> <p><b>Hello World</b></p> <p>This is a test of the URL <a href="http://www.example.com"> Example</a></p> <p><b>This text is bold</b></p> <p><em>This text is emphasized</em></p> <p><code>This is computer output</code></p> <p>This is<sub> subscript</sub> and <sup>superscript</sup></p> </body>
我想通过在资源strings.xml
声明html来将其显示在对话框中。 我该怎么做?
在strings.xml中添加html源代码的最好方法是使用<![CDATA[html source code]]>
。 这里是一个例子:
<string name="html"><![CDATA[<p>Text<p>]]></string>
然后你可以在TextView中使用下面的方式显示这个html:
myTextView.setText(Html.fromHtml(getString(R.string.html)));
如果你在你的html中有链接,并且希望它们是可点击的,请使用下面的方法:
myTextView.setMovementMethod(LinkMovementMethod.getInstance());
这里是大部分的例子。 我不认为pre
标签是支持的。
这是strings.xml
文件:
<?xml version="1.0" encoding="utf-8"?> <resources> <string name="app_name">Formatting</string> <string name="link"><b>Hello World</b> This is a test of the URL <a href="http://www.example.com/">Example</a></string> <string name="bold"><b>This text is bold</b></string> <string name="emphasis"><em>This text is emphasized</em></string> <string name="sup">This is <sub>subscript</sub> and <sup>superscript</sup></string> </resources>
这是布局。 请注意,链接实际上是可点击的,还有一些额外的工作需要:
<?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical"> <TextView android:id="@+id/test1" android:linksClickable="true" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="12dp" android:text="" android:textAppearance="?android:attr/textAppearanceMedium"/> <TextView android:id="@+id/test2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="12dp" android:text="" android:textAppearance="?android:attr/textAppearanceMedium"/> <TextView android:id="@+id/test3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="12dp" android:text="" android:textAppearance="?android:attr/textAppearanceMedium"/> <TextView android:id="@+id/test4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="12dp" android:text="" android:textAppearance="?android:attr/textAppearanceMedium"/> </LinearLayout> </ScrollView>
最后,代码:
TextView test1 = (TextView)findViewById(R.id.test1); Spanned spanned = Html.fromHtml(getString(R.string.link)); test1.setMovementMethod(LinkMovementMethod.getInstance()); test1.setText(spanned); TextView test2 = (TextView)findViewById(R.id.test2); test2.setText(Html.fromHtml(getString(R.string.bold))); TextView test3 = (TextView)findViewById(R.id.test3); test3.setText(Html.fromHtml(getString(R.string.emphasis))); TextView test4 = (TextView)findViewById(R.id.test4); test4.setText(Html.fromHtml(getString(R.string.sup)));
String.xml可以包含HTML实体,如下所示:
<resources> <string name="hello_world"><span></string> </resources>
在你的代码中: getResources().getString(R.string.hello_world);
将评估为"<span>"
。 你可以像这样使用这个HTML格式的文本:
TextView helloWorld = (TextView)findViewById(R.id.hello_world); helloWorld.setText(Html.fromHtml(getString(R.string.hello_world)));
在Android文档中解释了XML资源系统支持的所有样式。
string资源:格式和样式
任何包含的东西都可以直接在TextView
上使用和设置。 如果您需要使用更多的HTML标记,则需要将原始HTML(包含<
, >
等的转义字符)放入资源中,并将整个东西加载到WebView
。
这为我工作:
