[android] Calling activity function from separate class
Views 1320 Comment 0
Javascript를 통해 Activity의 함수를 호출할 때,
예제는 finish();를 호출해서 현재 창을 닫는다.
Using the linked page as an example, you should be able to do something like this:
WebAppInterface class
public class WebAppInterface { Activity mActivity; /** Instantiate the interface and set the activity */ WebAppInterface(Activity activity) { mActivity = activity; } /** Finish activity from the web page */ @JavascriptInterface public void finishActivity() { mActivity.finish(); } }
Now, in your activity you add the JS interface like this:
WebViewActivity
WebView webView = (WebView) findViewById(R.id.webview); webView.addJavascriptInterface(new WebAppInterface(this), "Android");
And in your webpage, you can finish the activity by clicking a button, like this:
HTML Contents
<input type="button" value="Finish the activity now" onClick="finishActivity()" /> <script type="text/javascript"> function finishActivity() { Android.finishActivity(); } </script>
