Android: html di strings.xml

Question 1

Saya ingin menampilkan misalnya kode html ini:

<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>

Saya ingin menampilkannya di Dialog dengan mendeklarasikan html di resource strings.xml. Bagaimana saya bisa melakukannya?

Question 2

Cara terbaik untuk menambahkan kode sumber html di strings.xml adalah dengan menggunakan <![CDATA[html source code]]>. Berikut ini contohnya:

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

Kemudian Anda dapat menampilkan html ini di TextView menggunakan:

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

Jika Anda memiliki link di html Anda dan ingin agar dapat diklik, gunakan metode ini:

myTextView.setMovementMethod(LinkMovementMethod.getInstance());

Question 3

Berikut sebagian besar contohnya. Saya rasa pretag tersebut tidak didukung.

masukkan deskripsi gambar di sini

Ini adalah strings.xmlfilenya:

<?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>

Berikut tata letaknya. Perhatikan agar tautan benar-benar dapat diklik, ada sedikit pekerjaan tambahan yang diperlukan:

<?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>

Terakhir, kode:

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 dapat berisi entitas HTML, seperti:

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

Dalam kode Anda: getResources().getString(R.string.hello_world);akan mengevaluasi ke "<span>". Anda dapat menggunakan teks berformat HTML ini seperti ini:

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

Question 5

Semua gaya yang didukung oleh sistem sumber daya XML dijelaskan dalam dokumentasi Android.

Sumber Daya String: Pemformatan dan Gaya

Apa pun yang disertakan di sana dapat digunakan dan disetel langsung TextView. Jika Anda perlu menggunakan markup HTML lebih lanjut, Anda perlu menempatkan HTML mentah (dengan karakter yang di-escape untuk <, >dan semacamnya) ke dalam sumber daya dan memuat semuanya di file WebView.

Question 6

Ini Berhasil untuk saya:
