我有另一个问题,在HTML内容中有一个标记

在此图像中没有显示.

Answer 1

1. 使用web.loadDataWithBaseURL而不是web.loadData(并且不要忘记在需要的地方转义字符串)
2. 您需要添加Internet权限才能下载图像并在清单文件中查看它们.

这个例子对我有用:

public class SimpleMusicStream extends Activity {
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.main);

        WebView wv = (WebView) findViewById(R.id.WebView01);        

        final String mimeType = "text/html";
        final String encoding = "UTF-8";
        String html = "<br /><br />Read the handouts please for tomorrow.<br /><br /><!--homework help homework" +
                "help help with homework homework assignments elementary school high school middle school" +
                "// --><font color='#60c000' size='4'><strong>Please!</strong></font>" +
                "<img src='http://www.homeworknow.com/hwnow/upload/images/tn_star300.gif'  />";


        wv.loadDataWithBaseURL("", html, mimeType, encoding, "");
    }

}

别忘了添加:

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

在AndroidManifest.xml文件中

您可以按上述方式执行此操作,也可以将html文件放入资产文件夹中,然后使用它来显示它

view.loadUrl("file:///android_asset/FILENAME.html");
