Android在Fragment中不调用onActivityResult()的解决办法

将Activity继承这个BaseFragmentActivity

解决办法就是，将你出问题的Fragment所在的Activity，来继承这个FragmentActivity，重写onActivityResult(),即可。

/**
 *  让子activity继承这个activity，Fragment去调用startActivityForResult，也可以收到onActivityResult

public class MyBaseFragmentActivity extends FragmentActivity {

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        //获取Fragment管理类
        FragmentManager manager=getSupportFragmentManager();
        //遍历Fragments
        for(int i=0;i<manager.getFragments().size();i++) {
            Fragment fragment=manager.getFragments().get(i);
            //fragment不为空就去调用onActivityResult()
            if(fragment!=null)
                callActivityResult(fragment,requestCode,resultCode,data);
        }
    }
    /**
     * 对所有子Fragment执行onActivityResult()
     */
    private void callActivityResult(Fragment fragment,int requestCode,int resultCode,Intent data) {
        //调用每个Fragment的onActivityResult()
        fragment.onActivityResult(requestCode, resultCode, data);
        //获取子Fragment
        List<Fragment> childFragment = fragment.getChildFragmentManager().getFragments(); 
        if(childFragment!=null)
            for(Fragment f:childFragment)
                if(f!=null)
                    callActivityResult(f, requestCode, resultCode, data);
    }
