I am sure this is too late but adding the method which worked for me in case somebody else comes here looking for solution.
Once the page finishes loading, I am injecting a javascript method to callback me JS hook. And in this method I am passing the size of .
private void setupWebView() {
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
webView.loadUrl("javascript:MyApp.resize(document.body.getBoundingClientRect().height)");
super.onPageFinished(view, url);
}
});
webView.addJavascriptInterface(this, "MyApp");
}
@JavascriptInterface
public void resize(final float height) {
MyActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
webView.setLayoutParams(new LinearLayout.LayoutParams(getResources().getDisplayMetrics().widthPixels, (int) (height * getResources().getDisplayMetrics().density)));
}
});
}
The same solution can also be seen here.
