android - 在手机屏幕中移动 Pg

Question

嗨，我尝试只为 Android 做一个视频游戏，但我不能使用 c 或其他环境。我不明白如何使用路径来移动我的图像，因为 pathinterpolator 请求从 (0,0) 开始并在 (1,1) 结束，但是如果我想在 (x,y) 中移动 al 我该怎么做? 我已经写了 onTouchEvent 的一部分，但我不理解文档。请帮助我和所有人。

这是我的方法 @Override public boolean onTouchEvent(MotionEvent event) {

    int action = event.getActionMasked();
    float newX = event.getX();
    float newY = event.getY();

    switch (action) {
        case (MotionEvent.ACTION_DOWN):
            Log.d(DEBUG_TAG, "Action was DOWN");
            Path path = new Path();
            path.moveTo(newX,newY);
            PathInterpolator pathInterpolator = new PathInterpolator(path);
            

            ObjectAnimator animation = ObjectAnimator.ofFloat(PG, "translationX", 100f);
            animation.setInterpolator(pathInterpolator);
            animation.start();

            break;
        case (MotionEvent.ACTION_MOVE):
            Log.d(DEBUG_TAG, "Action was MOVE");
            break;
        case (MotionEvent.ACTION_UP):
            Log.d(DEBUG_TAG, "Action was UP");
            break;
        case (MotionEvent.ACTION_CANCEL):
            Log.d(DEBUG_TAG, "Action was CANCEL");
            break;
        case (MotionEvent.ACTION_OUTSIDE):
            Log.d(DEBUG_TAG, "Movement occurred outside bounds " +
                    "of current screen element");
            break;
    }
    return true;
}
