(FAB) webview 应用程序上带有 (Share Provider ) 的浮动操作按钮

Question

我想在我的 webview 上使用 android 浮动操作按钮 (FAB) 作为分享操作按钮 >> 将当前 url 分享到 (facebook - whatsapp ....etc)

这里是代码

public class MainActivity extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener {

//initializing webview
private WebView mwebView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
        }
    });
