android - 旋转二维图像onclick android

Question

我想旋转 imageView 的图像，我已经使用矩阵缩放图像但旋转有问题，我正在使用代码...

int previousDegrees = 0;
        int degrees = 90;
        RotateAnimation animation = new RotateAnimation(previousDegrees,degrees,160,160);
        ImageView imageView = (ImageView)findViewById(R.id.imageView);
        animation.setDuration(1000);//Set the duration of the animation to 1 sec.
        imageView.startAnimation(animation);

它旋转图像一秒钟然后退回到原来的位置..有什么方法可以让图像连续旋转onclick..就像在(0,90.180.270,360)度... 请任何帮助!

Answer 1

像这样设置这些参数:

    animation.setFillEnabled(true);
    animation.setFillAfter(true);

来自 Android Developers Reference :

If fillAfter is true, the transformation that this animation performed will persist when it is finished.
