尝试这样

String base = Environment.getExternalStorageDirectory().getAbsolutePath().toString();
String imagePath = "file://"+ base + "/image_name.jpg";
String html = "<html><head></head><body> <img src=\""+ imagePath + "\"> </body></html>";
webView.loadDataWithBaseURL("", html, "text/html","utf-8", "");
