在错误行中,我有以下代码：

button_my.setonClickListener(new View.OnClickListener() {

                public void onClick(View v) {

                    objectAnimator = ObjectAnimator.ofFloat(miscrol, "scrollY", 0, 480).setDuration(3000);
                    objectAnimator.start();

                }
            });

和我的代码：

public void onClick(View v) {

                    ObjectAnimator objectAnimator= ObjectAnimator.ofInt(miscrol, "scrollY", 0, 480).setDuration(3000);
                    objectAnimator.start();

                }

解决方法:

检查您的进口.

您正在使用Android的ObjectAnimator,该API在您的API级别上不可用. NineOldAndroids具有自己的(com.nineoldandroids.animation.ObjectAnimator).
