I have a RelativeLayout
with WebView
. I am loading some generated html text into that WebView
. After loading the data WebView
height exceeding the screen. Now I need the height of the entire WebView
. Till now I tried WebView#getHeight()
, WebView#getBottom()
but I'm getting the height of visible content.
Finally I got the answer for my question. Here is the answer.
After loading WebView
we will get call in WebViewClient#onPageFinished
there we need to call javascript to get the height of full content of WebView
WebViewClient
class
/**
* Custom web client to perform operations on WebView
*/
class WebClient extends WebViewClient {
@Override
public void onPageFinished(WebView view, String url) {
view.loadUrl("javascript:AndroidFunction.resize(document.body.scrollHeight)");
}
}
}
After that we will get callback with height in WebInterface
class which is Registered as JavascriptInterface
/**
* WebView interface to communicate with Javascript
*/
public class WebAppInterface {
@JavascriptInterface
public void resize(final float height) {
float webViewHeight = (height * getResources().getDisplayMetrics().density);
//webViewHeight is the actual height of the WebView in pixels as per device screen density
}
}
