Android 如何将呼叫按钮更改为链接按钮

我只是个android新手， 如何将呼叫按钮更改为twitter/facebook或链接网站的链接按钮

 // ------------ Call button---------------------
        private void call() {
            try {
                Intent callIntent = new Intent(Intent.ACTION_CALL);
                callIntent.setData(Uri.parse("tel:"+Info.phoneNumber+""));
                startActivity(callIntent);
            } catch (ActivityNotFoundException activityException) {

            }
        }

        public void btnPhone(View v) {

            try {

                call();

            } catch (Exception e) {
                // TODO: handle exception
            }

        }

你需要像这样更新

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);

public static String phoneNumber = "+xxxxxx";

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);
