I create webview in code. In this webview I show pictures. Now I have two questions. How I can show image in full size, because my pictures has resolution 1381×1829 and I see only part of this picture. And second. As you can see in code I load pictures from assets, but I want to load pictures from sd card. How I can do that?

This is code:

    WebView web = new WebView(getContext());
web.getSettings().setJavaScriptEnabled(true);
web.getSettings().setBuiltInZoomControls(true);
web.loadUrl("file:///android_asset/lj.png");


addView(web);

    This method webview.getSettings().setBuiltInZoomControls(true) will let you implement build in zoom control for non-multitletouch screen

    You can load image from anywhere from sdcard to webview using this code.
    That is if u want to load multiple image from multiple location.

    String base = Environment.getExternalStorageDirectory().getAbsolutePath().toString() + "/Your/Folder";
String imagePath = "file:/"+ base + "/test.jpg";
String html = "<html><head></head><body><img src=\""+ imagePath + "\"></body></html>";
mWebView.loadData(html, "text/html","utf-8");

    But if u want to load images exist under the same parent folder, this will do the trick

    String imagePath = "test.jpg";
String html = "<html><head></head><body><img src=\""+ imagePath + "\"></body></html>";
mWebView.loadDataWithBaseURL("file:///mnt/sdcard/Your/Folder/", html, "text/html","utf-8",null);

    BE WARN, if u try to load hi-res image like 1600×1840 to webview, webview WILL reduced image res to maintain memory usage, which result in BAD looking image
