Android WebView, Scaling Image to fit the screen
What I have: I'm loading image from a URL. I simply do (WebView).loadUrl(imageurl, extraheaders)
What I get: Image is not showing at full width of the WebView, it has blank space all around (like if you open a little iamge in your desktop browser)
What i tried: Setting LayoutAlgorithm to SINGLE_COLUMN. Works perfect, but zooming doesn't work. (I have it enabled in the WebView.getSettings() Dont know why. Setting setUseWideViewPort(true); load image without any blanks space, but it is fully zoomed in.
Answer
You could also do something like this.
Add CSS style for img at the beginning (depends on your web data format) of your data string.
<style>img{display: inline; height: auto; max-width: 100%;}</style>
To quickly do it to data in WebView i did this.
WebView content = (WebView) findViewById(R.id.webView1);
content.loadDataWithBaseURL(null, "<style>img{display: inline;height: auto;max-width: 100%;}</style>" + post.getContent(), "text/html", "UTF-8", null);
It's pretty much like what bansal21ankit said, but instead it will work on every image in your HTML without extra work.
Edit (clarification on post content):
You can have any text/html value instead of post.getContent() from the example.
Post content here is just an example of a text/html content which is loaded from some data source and then concatenated with the style part which makes any image in given content to fit the screen.
