fragment的onActivityResult沒有調用的解決方法

1.不要用getActivity().startActivityForResult，直接在fragment中startActivityForResult
2.Fragment中重寫onActivityResult方法，在Fragment所屬的Activity中，也重寫onActivityResult方法。然後調用這個fragment中的onActivityResult()。

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        //this.getSupportFragmentManager().findFragmentByTag(DemoFragment.class.getSimpleName()).onActivityResult(requestCode, resultCode, data);
        fragmentSettings.onActivityResult(requestCode, resultCode, data);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);;
    }
