What is this webview popup dialog?

what is this kind of window that pops up referred to as?

and is there a way to apply it to my webvie开发者_Python百科w for popups? (I can ask this in a separate question if needed)

I suppose you want to show a popup windows which contain a webview from a webview in your application.

Two steps needed. First you need to Override the onJSAlert() method in the WebChromeClient class to enable popup window in webview:

public class MyWebChromeClient extends WebChromeClient {
        @Override
        public boolean onJsAlert(WebView view, String url, String message, JsResult jsResult) {
            final JsResult finalJsResult = jsResult;
            new AlertDialog.Builder(view.getContext()).setMessage(message).setPositiveButton(android.R.string.ok, new AlertDialog.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    finalJsResult.confirm();
                }
            }).setCancelable(false).create().show();
            return true;
        }
    }

and add this to your webview:

MyWebChromeClient myWebChromeClient = new MyWebChromeClient();
webView.setWebChromeClient(myWebChromeClient);

Then you can add custom webview in your AlertDialog (to replace the AlertDialog above):

public OnClickListener imageButtonViewOnClickListener = new OnClickListener() {
        public void onClick(View v) {

            LayoutInflater inflater = LayoutInflater.from(MyActivity.this);             
            View alertDialogView = inflater.inflate(R.layout.alert_dialog_layout, null);
            WebView myWebView = (WebView) findViewById(R.id.DialogWebView);
            myWebView.loadData(webContent, "text/html", "utf-8");
            AlertDialog.Builder builder = new AlertDialog.Builder(MyActivity.this);
            builder.setView(alertDialogView);
            builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    dialog.cancel();
                }
            }).show();
        }
    };

The xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:orientation="vertical">
<webView android:id="@+id/DialogWebView" android:layout_height="wrap_content"
    android:layout_width="fill_parent" android:layout_marginLeft="20dip"
    android:layout_marginRight="20dip" android:textAppearance="?android:attr/textAppearanceMedium" />
