android – 如何将存储在字节数组中的图像加载到WebView？

WebView wv = (WebView)findViewById(R.id.WebView01);
wv.loadDataWithBaseURL(null,"<img src=\"abc.jpg\">","text/html","UTF-8",null);

据我所知,没有办法满足所有这三个要求.如果您不想将其写入存储,Base64对其进行编码并将其直接加载到图像标签中可能是您​​最好的选择,尽管您仍然可以将其写入内部存储并在webview中显示.

private static final String HTML_FORMAT = "<img src=\"data:image/jpeg;base64,%1$s\" />";

private static void openJpeg(WebView web,byte[] imagE)
{
    String b64Image = Base64.encode(image,Base64.DEFAULT);
    String html = String.format(HTML_FORMAT,b64ImagE);
    web.loadData(html,"utf-8");
}
