我有一个项目列表,我正在使用Firebase回收站视图UI库适配器加载,现在我想从客户端(而不是数据库)的其他活动更新/刷新这些项目中的单个元素?我怎么能这样做?
MyViewholder:
public class LessonViewHolder extends RecyclerView.ViewHolder {
public TextView title;
public TextView short_title;
public ImageView lessonIconView;
private FirebaseRecyclerAdapter<Lesson, LessonViewHolder> mAdapter;
public LessonViewHolder(View view) {
super(view);
title = (TextView) view.findViewById(R.id.cardTitle);
lessonIconView =(ImageView) view.findViewById(R.id.lesson_icon);
short_title = (TextView) view.findViewById(R.id.text_title);
}
public void bindToPost(Lesson post) {
// Log.d("Post", String.valueOf(post));
if(post.getTitle() !=null)
{
title.setText(Html.fromHtml(post.getTitle()));
}
if(post.getShort_title()!=null) {
short_title.setText(Html.fromHtml(post.getShort_title()));
}
if (post.getIcon() != null) {
if(post.getColor()!=null) {
TextDrawable drawableHindi = TextDrawable.builder()
.buildRound(String.valueOf(getLayoutPosition() + 1), Color.parseColor(post.getColor()));
lessonIconView.setImageDrawable(drawableHindi);
}
else {
Picasso.with(itemView.getContext()).load(post.getIcon()).into(lessonIconView);
}
}
}
}
我的片段:
LessonViewHolder.class, ref) {
@Override
protected void populateViewHolder(final LessonViewHolder viewHolder, final Lesson model, final int position) {
viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
AppEventsLogger logger = AppEventsLogger.newLogger(getActivity());
logger.logEvent("ClickedLessonItem;"+ Locale.getDefault()+";"+position);
}
}
详细说明:
我正在通过Firebase ui适配器从Firebase数据库加载项目,现在点击一个项目就打开了一个Web视图活动,在webview活动中{I}}事件之后,我需要更新项目中的一个特定项目在循环器视图中显示,请注意我需要更新客户端的项目而不是数据库。
我的网页浏览活动:
