Question

我需要这个布局文件的帮助。问题是在Android Studio预览中显示它应该显示，图像底部有一个标题，FAB下的ScrollView中有文本。我很抱歉这个冗长的xml。

            android:layout_alignParentRight="true"
            android:layout_alignParentEnd="true" />

    </RelativeLayout>

</LinearLayout>

这是初始化代码

ImageView headerImage = (ImageView) linearLayout.findViewById(R.id.detailed_image_view);
        TextView title = (TextView) linearLayout.findViewById(R.id.detailed_title);
        TextView date = (TextView) linearLayout.findViewById(R.id.detailed_date);
        TextView location = (TextView) linearLayout.findViewById(R.id.detailed_location);
        TextView price = (TextView) linearLayout.findViewById(R.id.detailed_price);
        TextView text = (TextView) linearLayout.findViewById(R.id.detailed_text);
        FloatingActionButton fab = (FloatingActionButton) linearLayout.findViewById(R.id.fab);

        EventModel eventModel = bundle.getParcelable("event");

        Glide.with(context)
                .load(eventModel.getImage())
                .diskCacheStrategy(DiskCacheStrategy.ALL)
                .into(headerImage);

        title.setText(eventModel.getTitle());
        date.setText(eventModel.getDateString());
        price.setText("Free");
        location.setText(eventModel.getHost());
        text.setText(eventModel.getText());

这是它应该看起来的样子，但我在手机上得到的不是＆＃34; [PLACEHOLDER]＆＃34;和lorem ipsum文本

Android TextViews没有出现
