Android add image to webview from a drawable
I'd like something:
s="
<body>
<img src='"+R.drawable.picture+"'>
</body>";
How can I开发者_StackOverflow do this?
You can only do such a thing if our image is inside your /assets folder. Also, you must load your html with a baseUrl that's inside your assets folder.
You can use WebView.loadUrl() or WebView.loadDataWithBaseURL():
webView.loadUrl("file:///android_asset/file.html");
or
webView.loadDataWithBaseURL("file:///android_asset/", "<img src='file.jpg' />", "text/html", "utf-8", null);
(file.jpg should be inside your assets folder)
After some experimenting I found that the following HTML worked on Android 2.3.1 (but not on older versions):
<img src="file:///android_res/drawable/example.png"/>
The really cool part is that the image file was actually in the directory drawable-hdpi but the resource manager provides the image in the standard directory drawable.
Try this:
web_object.loadDataWithBaseURL("file:///android_res/drawable/", "<img src='test.jpg' />", "text/html", "utf-8", null);
no need to make seprate html file
Set Image Width 100%.
wv.loadDataWithBaseURL("file:///android_res/drawable/", "<img src='"+ url + "' style='width:100%' />", "text/html", "utf-8", null);
wv.getSettings().setBuiltInZoomControls(true);
wv.getSettings().setDisplayZoomControls(false);
加载中,请稍侯......
