Java 无法调用子片段的onActivityResult

我已经使用sharelockfragment实现了抽屉。我试图从gallery中选取图像，但该函数是在ChildFragment（

FragmentTab1.java

）中实现的。调用

startActivityForResult

时，该方法被重定向到Drawer.java类的

onActivityResult

方法。在这之后，它被重定向到

Fragment1.java

（父片段），但是我无法访问子片段（

FragmentTab1

）

onActivityResult

。我什么都试过了，在stackoverflow里到处都找过了，但运气不好。提前谢谢

Drawer.java（主要活动）

片段tab1.java（子片段）
