Displaying a downloaded image in Webview

Inman · Apr 26, 2013

As the title says, I have an image that was downloaded with HttpClient (to DirInternal or External). Since I want to provide pinch-to-zoom gestures, I am thinking of displaying this image inside a webview. But I am not sure how to specify the path to this image.

Any idea?

Here is an example:

B4X:

Sub Activity_Create(FirstTime As Boolean)
   Dim wv As WebView
   wv.Initialize("")
   Activity.AddView(wv, 0, 0, 50%x, 50%y)
   wv.LoadHtml("<img src=""file://" & File.Combine(File.DirRootExternal, "1.jpg") & """/>") 
End Sub

Hi Erel

i tried your code , but if i try to show an large image , bigger than screen , the image doesn't been resized, is there a way to show all the image into the webview even though the image is bigger then the webview?

Thanks

You can call wv.Zoom until it returns False.
