Android: How can I Open a WebView in a Popup Window?

Question

I already have a WebView with content loaded and I need to select text that will open a new WebView in a popup window. The popup will contain a form which I will submit and when I hit enter it will save data and close the popup. At this stage, I need help in opening the WebView popup by selecting text or clicking button.

I have tried the answer from https://stackoverflow.com/a/9173368/2341601 but this crashes the app when I do

WebView wv = new WebView(this);

LogCat message:

final Dialog dialog = new Dialog(context);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.webview_layout);

WebView wv = (WebView) dialog
            .findViewById(R.id.webview);

wv.loadUrl("http:\\www.google.com");
wv.setWebViewClient(new WebViewClient() {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);

        return true;
    }
});

dialog.setOnKeyListener(new OnKeyListener() {

        @Override
        public boolean onKey(DialogInterface dialog, int keyCode,
                KeyEvent event) {
            if (keyCode == KeyEvent.KEYCODE_BACK) {

                dialog.dismiss();
            }

here , webview_layout is xml file and in that put one webview in it – Vaishali Sutariya Sep 25 '14 at 05:16
What's R.layout.webview_layout? Code does not compile if I use the WebView's layout. I also think it might be better to use a fragment instead of the Activity. – skzi Sep 25 '14 at 05:39
App still crashes at dialog.setContentView(R.layout.activity_webview); – skzi Sep 25 '14 at 06:01
I am aware of R.layout.webview_layout - I am just not sure if by "webview_layout", you are referring to the activity's layout or not. – skzi Sep 25 '14 at 06:03
this is simple layout file which is store in layout folder – Vaishali Sutariya Sep 25 '14 at 06:04

Avoid request future crash.

DialogFragment.java

public class DialogFragment extends android.support.v4.app.DialogFragment {

private boolean isModal = false;

public static DialogFragment newInstance()
{
    DialogFragment frag = new DialogFragment();
    frag.isModal = true; // WHEN FRAGMENT IS CALLED AS A DIALOG SET FLAG
    return frag;
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
{
    if(isModal) // AVOID REQUEST FEATURE CRASH
    {
    return super.onCreateView(inflater, container, savedInstanceState);
    }
    else
    {
    View view = inflater.inflate(R.layout.dialog_webview, container, false);
    setupUI(view);
    return view;
    }
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    // Get the layout inflater

    View view = getActivity().getLayoutInflater().inflate(R.layout.dialog_webview, null);

    builder.setView(view);
    WebView wv = (WebView) view.findViewById(R.id.webView);

    wv.loadUrl("http:\\www.google.com");
    wv.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);

            return true;
        }
    });
    return builder.create();
}
}

Thanks but the application is crashing in the last line - df.show(getSupportFragmentManager(), "dialog"); — skzi, Sep 25 '14 at 07:14
May be android-support-v7-appcompat.jar is missing from your libs folder(android.support.v4.app.FragmentActivity.getSupportFragmentManager()). post your logcat also.... — raja, Sep 25 '14 at 08:19
The support libraries are not in the libs folder, however, I have these defined in build.gradle file and the relevant xml files are also present in .idea\libraries folder. I checked the SDK manager and the support libraries are installed. — skzi, Sep 26 '14 at 01:14
