推荐答案
您可以使用的WebView 此：
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setAllowFileAccess(true);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setBuiltInZoomControls(true);
String base = Environment.getExternalStorageDirectory().getAbsolutePath().toString();
String imagePath = "file:/"+ base + "/test.jpg";
String html = "<html><head></head><body><img src=\""+ imagePath + "\"></body></html>";
mWebView.loadData(html, "text/html","utf-8");
