Android旋转/连续旋转图像，直到我命令它停止 [英] android spin / continuously rotate an image untill I command it to stop

问题描述

我想制作一个新图标。

I want to make a little fresh icon.

当我单击它时，我希望它像进度对话框一样旋转，直到刷新完成，然后它必须停止旋转。

When I click on it, I want it to spin like a progress dialog, until my refresh is completed, then it must stop spinning.

如何实现？

我尝试了如下动画：

RotateAnimation rotateAnimation = new RotateAnimation(30, 90,
                    Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);                
            refreshBtn.startAnimation(rotateAnimation);

但这只会旋转一次或两次然后停止。

but that only rotates once or twice and then stops.

推荐答案

尝试一下：

RotateAnimation rotateAnimation = new RotateAnimation(30, 90,
                        Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
rotateAnimation.setRepeatCount(Animation.INFINITE);
rotateAnimation.setRepeatMode(Animation.RESTART);
refreshBtn.startAnimation(rotateAnimation);
