Android：strings.xml中的html

Question 1

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>

我想通过在资源中声明html在对话框上显示它strings.xml。我该怎么做？

Question 2

在strings.xml中添加html源代码的最佳方法是使用<![CDATA[html source code]]>。这是一个例子：

<string name="html"><![CDATA[<p>Text</p>]]></string>

然后，您可以使用以下方法在TextView中显示此html：

myTextView.setText(Html.fromHtml(getString(R.string.html)));

如果您的html中包含链接，并且希望它们可被单击，请使用以下方法：

myTextView.setMovementMethod(LinkMovementMethod.getInstance());

Question 3

这是大多数示例。我认为该pre标签不受支持。

在此处输入图片说明

这是strings.xml文件：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">Formatting</string>
    <string name="link">&lt;b&gt;Hello World&lt;/b&gt; This is a test of the URL &lt;a href="http://www.example.com/"&gt;Example&lt;/a&gt;</string>
    <string name="bold">&lt;b&gt;This text is bold&lt;/b&gt;</string>
    <string name="emphasis">&lt;em&gt;This text is emphasized&lt;/em&gt;</string>
    <string name="sup">This is &lt;sub&gt;subscript&lt;/sub&gt; and &lt;sup&gt;superscript&lt;/sup&gt;</string>
</resources>

这是布局。请注意，要使链接实际上是可点击的，还需要做一些额外的工作：

<?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)));

Question 4

String.xml可以包含HTML实体，如下所示：

<resources>
    <string name="hello_world">&lt;span&gt;</string>
</resources>

在您的代码中：getResources().getString(R.string.hello_world);将计算为"<span>"。您可以使用以下HTML格式的文本：

TextView helloWorld = (TextView)findViewById(R.id.hello_world);
helloWorld.setText(Html.fromHtml(getString(R.string.hello_world)));

Question 5

Android文档中介绍了XML资源系统支持的所有样式。

字符串资源：格式和样式

此处包含的所有内容都可以使用并直接设置在上TextView。如果你需要使用另外的HTML标记，你将需要把原始的HTML（与转义字符<，>并且这样的）到资源和负载在整个事情WebView。

Question 6

这为我工作：

<?xml version="1.0" encoding="utf-8"?>

<string name="app_name">Sangamner College</string>
<string name="about_desc"><![CDATA[In order to make higher education available in the rural environment such as of Sangamner, Shikshan Prasarak Sanstha was established in 1960.
