- Use web.loadDataWithBaseURL instead of web.loadData (And don't forget to escape strings where it's needed)
- You need to add internet permission to download images and view them in your manifest file.
- 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）
- 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。
This example works for me:
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, "");
}
}
And don't forget to add:
并且不要忘记添加：
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
in your AndroidManifest.xml file
在您的 AndroidManifest.xml 文件中
