GoodView方法：

使用GoodView的Demo:

   public class MainActivity extends Activity {

        @Override        protected void onCreate(Bundle savedInstanceState) {            super.onCreate(savedInstanceState);            setContentView(R.layout.activity_main)            final GoodView goodView = new GoodView(this);            Button button = new Button(this);            button.setOnClickListener(new View.OnClickListener() {                @Override                public void onClick(View v) {                    goodView.setText("+1");                    goodView.show(v);                }            });        }    }
