GoodView方法:
使用GoodView的Demo:
public class MainActivity extends Activity {
@Overrideprotected 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() {@Overridepublic void onClick(View v) {goodView.setText("+1");goodView.show(v);}});}}
