Android facebook how to use webview

Question

I am using the following code to load a facebook button, like inside a webview.

            likeWebView = (WebView)findViewById(R.id.webview);
            likeWebView.getSettings().setJavaScriptEnabled(true);

            url ="http://www.facebook.com/plugins/like.php?" +
            "href=" + URLEncoder.encode( "http://developers.facebook.com/docs/opengraph/" )
            + "&" +
            "layout=button_count&" +
            "show_faces=0&" +
            "width=90&" +
            "height=24&" +
            "locale=en_IN" +
            "colorscheme=light" ;

            likeWebView.loadUrl( url );

the problem is when the user signs the process, redirects it to a blank page, how to intercept this web view request and cancel this action / close the web view?

Answer 1

In this case, I would use the WebViewClient method shouldOverrideUrlLoading.

likeWebView = (WebView)findViewById(R.id.webview);
likeWebView.getSettings().setJavaScriptEnabled(true);

likeWebView.setWebViewClient(new WebViewClient() {
    public boolean shouldOverrideUrlLoading (WebView view, String url) {
        if(url.contains("something")) return true;
        return false; //Default is to not override unless our condition is met.
    }
});

Answer 2

public class WebViewPreLoad extends WebView{
public WebViewPreLoad(Context context) {
       super(context);
}
    public void loadUrl(String str){
    if(str.contains("something"))
            super.loadUrl(str);
        else 
                     hide this
    }
}

of course you will need to find the correct "if" for ur case

do the same with

 public void loadUrl(String url, Map<String,String> extraHeaders)

change the super statement to:

super.loadUrl(url, extraHeaders);
