字符串资源中的HTML?

您也可以将HTML包围在一个CDATA块中,getString将返回实际的HTML。就像这样:

<string name="foo"><![CDATA[Foo Bar <a href="foo?id=%s">baz</a> is cool]]></string>

现在,当您执行getstring(r.string.foo)时,字符串将是html。如果需要通过可点击的文本视图呈现HTML(链接如图所示),则需要执行html.fromhtml(…)调用以获取可点击的文本。

看起来 getString() 就这样——得到一个 一串 . 要使用这个,你必须使用 getText() (不再是了 Html.fromHtml() ,即:

mTextView.setText(getText(R.string.my_styled_text));

然而,似乎 android:text 属性执行相同的操作,以下是等效的:

<TextView android:text="@string/my_styled_text" />

而在 strings.xml :

<string name="my_styled_text">Hello, <b>World</b>!</string>

最好的解决方案是以某种方式使用资源:

<string name="htmlsource"><![CDATA[<p>Adults are spotted gold and black on the crown, back and wings. Their face and neck are black with a white border; they have a black breast and a dark rump. The legs are black.</p><p>It is similar to two other golden plovers, Eurasian and Pacific. <h1>The American Golden Plover</h1> is smaller, slimmer and relatively longer-legged than Eurasian Golden Plover (<i>Pluvialis apricaria</i>) which also has white axillary (armpit) feathers. It is more similar to Pacific Golden Plover (<i>Pluvialis fulva</i>) with which it was once <b>considered</b> conspecific under the name \"Lesser Golden Plover\". The Pacific Golden Plover is slimmer than the American species, has a shorter primary projection, and longer legs, and is usually yellower on the back.</p><p>These birds forage for food on tundra, fields, beaches and tidal flats, usually by sight. They eat insects and crustaceans, also berries.</p>]]></string>

并用以下方式显示:

Spanned sp = Html.fromHtml( getString(R.string.htmlsource));
tv.setText(sp);

尝试在不使用和使用tv.settext(gettex(r.string.htmlsource))的情况下使用该资源,您将看到不同之处。

想法:将HTML放在JSON格式的文件中,并将其存储在/res/raw中。(JSON不那么挑剔)

将这样的数据记录存储在数组对象中:

[
    {
        "Field1": "String data",
        "Field2": 12345,
        "Field3": "more Strings",
        "Field4": true
    },
    {
        "Field1": "String data",
        "Field2": 12345,
        "Field3": "more Strings",
        "Field4": true
    },
    {
        "Field1": "String data",
        "Field2": 12345,
        "Field3": "more Strings",
        "Field4": true
    }
]

要读取应用程序中的数据:

private ArrayList<Data> getData(String filename) {
    ArrayList<Data> dataArray = new ArrayList<Data>();

    try {
        int id = getResources().getIdentifier(filename, "raw", getPackageName());
        InputStream input = getResources().openRawResource(id);
        int size = input.available();
        byte[] buffer = new byte[size];
        input.read(buffer);
        String text = new String(buffer);

        Gson gson = new Gson();
        Type dataType = new TypeToken<List<Map<String, Object>>>() {}.getType();
        List<Map<String, Object>> natural = gson.fromJson(text, dataType);

        // now cycle through each object and gather the data from each field
        for(Map<String, Object> json : natural) {
            final Data ad = new Data(json.get("Field1"), json.get("Field2"),  json.get("Field3"), json.get("Field4"));
            dataArray.add(ad);
        }

    } catch (Exception e) {
        e.printStackTrace();
    }

    return dataArray;
}

最后, Data 类只是一个公共变量容器,便于访问…

public class Data {

    public String string;
    public Integer number;
    public String somestring;
    public Integer site;
    public boolean logical;


    public Data(String string, Integer number, String somestring, boolean logical)
    {
        this.string = string;
        this.number = number;
        this.somestring = somestring;
        this.logical = logical;
    }
}

它对我来说没有CDATA块。

<string name="menu_item_purchase" translatable="false"><font color="red">P</font><font color="orange">r</font><font color="yellow">e</font><font color="green">m</font><font color="white">i</font><font color="blue">u</font><font color="purple">m</font></string>`enter code here`

我在布局中使用它。

<item
    android:id="@+id/nav_premium"
    android:icon="@drawable/coins"
    android:title="@string/menu_item_purchase"
    />
