可绘制围绕其中心机器人 [英] Drawable Rotating around its center Android

问题描述

我正奇怪的结果有以下code：

I am getting strange results with the following code:

iv = (ImageView) findViewById(R.id.iv);
        iv.setImageResource(R.drawable.spinner_white_76);

        Animation a = new RotateAnimation(0.0f, 360.0f,
                Animation.RELATIVE_TO_SELF, iv.getDrawable()
                        .getIntrinsicWidth() / 2, Animation.RELATIVE_TO_SELF,
                iv.getDrawable().getIntrinsicHeight() / 2);
        a.setRepeatCount(-1);
        a.setDuration(1000);

        iv.startAnimation(a);

请告诉我正确的方式来指定轴点（绘制中心）？

Whats the right way to specify the axis point (center of the drawable)?

推荐答案

觉得自己很蠢！心动不如花一些时间仔细阅读文档后工作：

Feel stupid! Got it to work after spending some time closely reading the documentation:

Animation a = new RotateAnimation(0.0f, 360.0f,
                Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,
                0.5f);
        a.setRepeatCount(-1);
        a.setDuration(1000);
