Android中多层Fragment嵌套，调用相册返回Uri无法显示图片的问题解决方法

imageView.setOnClickListener(new View.OnClickListener() {    @Override    public void onClick(View v) {       Intent intent = new Intent("android.intent.action.GET_CONTENT");       intent.setType("image/*");       getRootFragment().startActivityForResult(intent, 1);    }});

private Fragment getRootFragment() {    Fragment fragment = getParentFragment();    while (fragment.getParentFragment() != null) {        fragment = fragment.getParentFragment();    }    return fragment;}

@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {    if (requestCode == 1) {        Uri uri = data.getData();       //  注意此处不要直接调用 Glide.with(mCtx).load(path).into(imageView);否则，会无效       //  而是通过handler进行发送消息显示图片        if (uri != null) {            Message message = Message.obtain();            message.obj = uri;            handler.sendMessage(message);        }    }    super.onActivityResult(requestCode, resultCode, data);}

Handler handler = new Handler() {    @Override    public void handleMessage(Message msg) {        Uri path = (Uri) msg.obj;        Glide.with(mCtx)                .load(path)                .into(imageView);        super.handleMessage(msg);    }};
