android.util.AndroidRuntimeException: Animators may only be run on Looper threads-优快云博客

首先说说我自己的应用场景

我自定义了一个popupwindow，然后在show的时候提示了这个错，大致意思就是动画在子线程运行了

public void show() {
        Activity topActivity = ActivityUtils.getTopActivity();
        if (topActivity instanceof AppCompatActivity) {
            showAtLocation(topActivity.getWindow().getDecorView(), Gravity.CENTER, 0, 0);
        }
    }

既然已经提示的这么清楚了，那我就加个Looper.getMainLooper主线程操作，嗯就这样可以大致解决

new Handler(Looper.getMainLooper()).post(new Runnable() {
                    @Override
                    public void run() {
                        PopManager.get().show();
                    }
                });

重点重点：接下来我出发了另一个问题，场景是：我从activityA跳转到activityB，然后我activityB有个借口，我再借口请求的时候show，在请求结束后dismiss，然后就报了个错Unable to add window -- token null is not valid; is your activity running?
