Answer 1

To get the url just use WebView.getUrl(), but first we need to change some things

Then put WebView as an accessible variable between methods, thus:

public class MainActivity extends Activity
{
    //Floating Button
    ImageButton floatButton;

    WebView wv; //sua variavel

Then change the onCreate for this:

You had called twice super.onCreate and setContentView, is not necessary

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);

    wv = (WebView) findViewById(R.id.webView);

And finally access the variable wv so:

shareIntent.putExtra(Intent.EXTRA_TEXT, wv.getUrl());

It would look something like:

private Intent createShareIntent() {
    Intent shareIntent = new Intent(Intent.ACTION_SEND);
    shareIntent.setType("text/plain");
    shareIntent.putExtra(Intent.EXTRA_TEXT, wv.getUrl());
    return shareIntent;
}
