Android WebView Onjsalert Considerations

Recently, after using the Onjsalert method of WebView, I found that the HTML page clicked did not respond, the code is as follows:

Mwebview.setwebchromeclient (New Webchromeclient () {

			@Override public
			boolean Onjsalert (WebView view, String URL, String message,
					jsresult result) {
				
				if (message!=null) {
					
					//todo
					//Pop-up dialog
					Toast.maketext ( Getapplicationcontext (), message, Toast.length_long). Show ();
								
				return true;
			}

			@Override Public
			Boolean onjsconfirm (webview view, string URL,
					string message, jsresult result) {
				//TODO Auto-generated method stubs return
				super.onjsconfirm (view, URL, message, result);
			}

			@Override Public
			Boolean onjsprompt (webview view, string URL, String message,
					string defaultvalue, Jspromptresult result) {
				//TODO auto-generated method stub return
				super.onjsprompt (view, URL, message, DefaultValue, result);
			}
			
		);

Baffled, finally found the answer on the StackOverflow

Mwebview.setwebchromeclient (New Webchromeclient () {

			@Override public
			boolean Onjsalert (WebView view, String URL, String message,
					jsresult result) {
				
				if (message!=null) {
					
					//todo
					//Pop-up dialog
					Toast.maketext ( Getapplicationcontext (), message, Toast.length_long). Show ();
				
				Result.cancel ();	Be sure to cancel, otherwise there will be a variety of strange problems return
				true;
			}

			@Override Public
			Boolean onjsconfirm (webview view, string URL,
					string message, jsresult result) {
				//TODO Auto-generated method stubs return
				super.onjsconfirm (view, URL, message, result);
			}

			@Override Public
			Boolean onjsprompt (webview view, string URL, String message,
					string defaultvalue, Jspromptresult result) {
				//TODO auto-generated method stub return
				super.onjsprompt (view, URL, message, DefaultValue, result);
			}
			
		);

Return True and Result.cancel (); One can not be less, otherwise there will be a variety of strange problems.
