使用Hyphenator.js进行Android完全对齐和自动连字

标签: javascript android html android-webview hyphenation

我正在尝试使用自动连字功能完全证明Android中的文本。我按照here解释使用WebView实现了充分的理由。我已经在Android中阅读了几个关于自动连字的线程,但它们都没有应用于WebViews。我尝试过使用新的CSS3连字符:auto(包括-webkit-hyphens:auto),但Android WebKit还不支持它。

我发现了一篇博文here,其中提到了使用连字符JavaScript,但我不知道如何实现它(JavaScript和HTML是待办事项列表中的下一个)。由于.js文件的大小,我不想简单地使用webView.loadUrl("javascript:someFunction()");

以下是我目前使用的代码:

public class TestWebView extends Activity {
@Override
public void onCreate (Bundle savedState) {
    WebView webView;
    super.onCreate(savedState);
    webView = new WebView(this);
    setContentView(webView);
    WebSettings webSettings = webView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webView.loadUrl("file:///android_asset/WorkingExample.html");
    }
}

这是HTML:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html lang="en">
    <head>
        <title>Hyphenator.js</title>
        <meta http-equiv="content-type" content="text/html; charset=UTF-8">
        <style type="text/css">
            body {
                width:30%;
                margin-left:35%;
                margin-right:35%;
            }
            .text {
                text-align:justify;
            }
    </style>
    <script src="Hyphenator.js" type="text/javascript"></script>
    <script type="text/javascript">
        Hyphenator.config({
            displaytogglebox : true,
            minwordlength : 4
        });
        Hyphenator.run();
        </script>
    </head>
    <body>
        <h1>Example of using Hyphenator.js</h1>
        <h2>Deutsch</h2>
        <p class="hyphenate text" lang="de">Deutschsprachige Beispieltexte haben natürlicherweise längere Wortzusammensetzungen als englischsprachige. Aber auch <span lang="en">“hyphenation”</span> ist ein ziemlich langes Kompositum.</p>
        <p class="hyphenate text" lang="de">Verändern Sie die Fenstergrösse um den Effekt der Silbentrennung zu sehen.</p>
        <h2>English</h2>
        <p class="hyphenate text" lang="en">English words are shorter in the average then german words. <span lang="de">«Silbentrennungsalgorithmus»</span> for example is quite long.</p>
        <p class="hyphenate text" lang="en">Resize the window to see hyphenation in effect.</p>
        <h2>Links</h2>
        <p class="hyphenate text" lang="en">Not only words but also links like <a href="http://code.google.com/p/hyphenator/">http://code.google.com/p/hyphenator/</a> are processed. But in a special manner (using zero width space).</p>
    </body>
</html>

与html文件一起存储的是Hyphenator.js文件。在我的计算机浏览器中打开HTML文件按预期工作,但在手机上我没有运气:Computer browser (FF) vs WebView 最终,我希望动态生成文本,但只是让它工作将是一个巨大的帮助。感谢。

WorkingExample.html中有Hyphenator.jsfile:///android_asset/吗?我想您忘了下载“模式”文件夹(在您需要de.js下需要en-us.jsfile:///android_asset/patterns/)。你可以得到他们here

MainActivity:

public class MainActivity extends Activity {

    WebView mWebView;
    String mText;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mText = "English words are shorter in the average then german words. <span lang=\"de\">Silbentrennungsalgorithmus</span> for example is quite long.";

        mWebView = (WebView) findViewById(R.id.mWebView);
        mWebView.getSettings().setJavaScriptEnabled(true);
        mWebView.loadUrl("file:///android_asset/WorkingExample.html");
        mWebView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(WebView view, String url) {
                mWebView.loadUrl("javascript:(function() { "
                        + "document.getElementById('text').innerHTML='" + mText
                        + "';" + "Hyphenator.run();" + "})()");
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

activity_main:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

以下库支持连字符。它为您执行所有类型的文本对齐(左/右/中心/对齐)和连字符。并非所有语言都已添加,但可以根据需要添加。此库使用 NO WEBVIEWS SUPPORTS SPANNABLES ,并允许 LONG TEXT

LIBRARY https://github.com/bluejamesbond/TextJustify-Android

ANDROID :2.2到5.X

<强> SETUP

DocumentView documentView = addDocumentView(new StringBuilder("Your long text content"), DocumentView.PLAIN_TEXT);
documentView.getDocumentLayoutParams().setTextAlignment(TextAlignment.JUSTIFIED);
documentView.getDocumentLayoutParams().setHyphenator(new Hyphenator(HyphenPattern.PT));
documentView.getDocumentLayoutParams().setHyphenated(true);
