通过（Thread+Handler)imgaeVide.setImageUri，但是报错 Only the original thread that created a view hierarchy can touch its views.
报错全部内容如下：
android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

Android的fragment类中可以通过handler更改ui界面嘛 如果不行那怎么办？
