我完全熟悉 ExpandableRecyclerview 或 ExpandableLayout 但我有一个有点独特的设计，我正在寻求帮助来实现这个实现。
我正在附加设计
当用户单击图像中显示的箭头时，CardView Recyclerview 应该在评论按钮和响应部分之间展开或膨胀一个 recyclerview。怎么做。我已经尝试过来自 ThoughtBot 的 ExpandableRecyclerview 和 ExpandableListView 所有这些组件都向父级添加了一个子级。
我正在使用 Thoughtbot 的 ExpandableRecyclerview，
com.thoughtbot.expandablerecyclerview
我的适配器如下所示。
public class ReviewRecyclerAdapter extends ExpandableRecyclerViewAdapter<ReviewViewHolder, CommentsViewHolder> {
private Context context;
public ReviewRecyclerAdapter(Context context,List<? extends ExpandableGroup> groups) {
super(groups);
this.context = context;
}
@Override
public ReviewViewHolder onCreateGroupViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.list_item_review, parent, false);
return new ReviewViewHolder(view);
}
@Override
public CommentsViewHolder onCreateChildViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.list_item_comments, parent, false);
return new CommentsViewHolder(view);
}
@Override
public void onBindChildViewHolder(CommentsViewHolder holder, int flatPosition, ExpandableGroup group, int childIndex) {
final CommentsModel comments = ((ReviewsModel) group).getItems().get(childIndex);
holder.setSubTitletName(comments.getComment());
}
@Override
public void onBindGroupViewHolder(ReviewViewHolder holder, int flatPosition, ExpandableGroup group) {
holder.setGenreTitle(context, group);
}
}
// 查看持有人
public class ReviewViewHolder extends GroupViewHolder {
private TextView titleName;
private ImageView arrow;
private ImageView icon;
public ReviewViewHolder(View itemView) {
super(itemView);
titleName = (TextView) itemView.findViewById(R.id.list_item_genre_name);
arrow = (ImageView) itemView.findViewById(R.id.list_item_genre_arrow);
}
public void setGenreTitle(Context context, ExpandableGroup title) {
if (title instanceof ReviewsModel) {
titleName.setText(title.getTitle());
if (((ReviewsModel) title).getReview()!= null && !((ReviewsModel) title).getReview().isEmpty()){
}
}
}
@Override
public void expand() {
animateExpand();
}
@Override
public void collapse() {
animateCollapse();
}
private void animateExpand() {
RotateAnimation rotate =
new RotateAnimation(360, 180, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
rotate.setDuration(300);
rotate.setFillAfter(true);
arrow.setAnimation(rotate);
}
private void animateCollapse() {
RotateAnimation rotate =
new RotateAnimation(180, 360, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
rotate.setDuration(300);
rotate.setFillAfter(true);
arrow.setAnimation(rotate);
}
}
public class CommentsViewHolder extends ChildViewHolder {
private TextView subTitleTextView;
public CommentsViewHolder(View itemView) {
super(itemView);
subTitleTextView = (TextView) itemView.findViewById(R.id.subtitle);
}
public void setSubTitletName(String name) {
subTitleTextView.setText(name);
}
}
