Swipe to refresh in webview

Hi guys,
My name's Harshith Royal and today I'm presenting you the code for SWIPE TO REFRESH IN WEBVIEW  so, let's start
In OnCreate, add this code by asd block

final android.support.v4.widget.SwipeRefreshLayout sr = new android.support.v4.widget.SwipeRefreshLayout(this);
sr.setLayoutParams(new LinearLayout.LayoutParams(android.widget.LinearLayout.LayoutParams.MATCH_PARENT, android.widget.LinearLayout.LayoutParams.MATCH_PARENT));
linear1.addView(sr);
final WebView wb = (WebView)findViewById(R.id.webview1);
wb.getSettings().setJavaScriptEnabled(true);
linear1.removeView(wb);
linear1.post(new Runnable() { @Override public void run() { sr.addView(wb); } });
wb.setWebViewClient(new WebViewClient() { public void onPageFinished(WebView view, String url) { sr.setRefreshing(false);
}});
wb.loadUrl("http://www.google.com");
sr.setOnRefreshListener( new android.support.v4.widget.SwipeRefreshLayout.OnRefreshListener() { @Override public void onRefresh() { wb.reload(); } } );

Here, wb is  your webview's ID

(LOL, MY FIRST POST 😅)
