我正在开发一款卡罗姆游戏。我试图通过在队列中添加动画来动画大约20个ImageViews（硬币）......单个视图（硬币）的动画很好但是当我完全动画时它变得非常慢。我希望所有的硬币同时没有问题。这是我写的代码。

switch (ID) {
case 1: // 43 float values

try {
FileWriter fstream = new FileWriter("/sdcard/carromjava.txt");
BufferedWriter out = new BufferedWriter(fstream);
out.write(Long.toString(timeinmill));
out.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//Close the output stream

请帮我如何做所有的动画顺利一起。我知道去OpenGL，但没有任何方法可以做到这一点。
答案 0 :(得分：0)
如果您使用UI类为每个对象设置动画并拥有许多具有同步动画的对象，则始终建议使用OpenGL等低级API。或者，如果您对学习OpenGL不满意，可以使用Cocoas 2D或其他优秀的API，这些API只能在低级API上创建强大的框架。
