我的问题是试图弄清楚如何在迭代图像后停止可绘制动画(例如,它返回到葡萄图像)。我当然不能使用我实现的方法,.ACTION.DOWN所以任何人都可以帮助我。

    public boolean onTouchEvent (MotionEvent event){
        Drawable currentFrame, checkFrame;
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            if (fruitAnimation.isRunning()) {
                fruitAnimation.stop();
                //The variable that will guard the frame number
                int frameNumber = 0;
                //Get the frame of the animation
                //Drawable currentFrame, checkFrame;
                currentFrame = fruitAnimation.getCurrent();
                //checks the position of the frame.
                for (int i = 0; i < fruitAnimation.getNumberOfFrames(); i++) {
                    checkFrame = fruitAnimation.getFrame(i);
                    if (checkFrame == currentFrame) {
                        frameNumber = i;
                        break;
                    }

                }
                String fruit = "";

                switch (frameNumber) {
                    case 0:
                        fruit = "Grapes";
                        break;
                    case 1:
                        fruit = "Lemon";
                        break;
                    case 2:
                        fruit = "Orange";
                        break;
                    case 3:
                        fruit = "Pear";
                        break;
                    case 4:
                        fruit = "Strawberry";
                        break;


                }
                Toast.makeText(this, fruit, Toast.LENGTH_SHORT).show();

            }else {
                fruitAnimation.start();


            }
            return true;
        }

        return super.onTouchEvent(event);
    }

你很可能这样做是错误的。由于您可以使用动画侦听器来监视您的动画,因此我将动画设置为一次性运行,然后在我的侦听器中,onAnimationEnd()我会检查我是否达到了极限,如果没有,则再次启动动画。
