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);
}
});

}
}
