開(kāi)源項(xiàng)目GoodView點(diǎn)贊效果代碼明細(xì)

點(diǎn)贊+1效果：

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);
????????????????}
????????????});

????????}
????}
