I use StickyGridHeader library with a custom header view like image below. The problem is this header only work when it's sticky on the top. On normal state, it show width size incorrectly, I think it caused by measuring header size from StickyGridHeadersGridView
Here is my header layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="10dp"
android:paddingTop="10dp" >
<TextView
android:id="#+id/tvHeaderName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_toLeftOf="#+id/tvHeaderDate"
android:minWidth="250dp"
android:paddingLeft="10dp"
android:text="aaa"
android:textColor="#color/white"/>
<TextView
android:id="#+id/tvHeaderDate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:paddingRight="10dp"
android:text="aaa"
android:textColor="#color/white" />
<!--gray line-->
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_below="#+id/tvHeaderDate"
android:layout_marginTop="10dp"
android:background="#color/gray_line" />
</RelativeLayout>
And my adapter:
public class GalleryAdapter extends BaseAdapter implements StickyGridHeadersBaseAdapter {
// initialize image item ...
#Override
public int getCountForHeader(int position) {
return getHeaderItem(position).getImages().size();
}
public GalleryItem getHeaderItem(int position) {
return parents.get(position);
}
#Override
public View getHeaderView(int position, View view, ViewGroup parent) {
HeaderViewHolder viewHolder;
if (view == null) {
view = mInflater.inflate(R.layout.item_header_gallery, parent, false);
viewHolder = new HeaderViewHolder();
viewHolder.tvHeaderName = (TextView) view.findViewById(R.id.tvHeaderName);
viewHolder.tvHeaderDate = (TextView) view.findViewById(R.id.tvHeaderDate);
view.setTag(viewHolder);
} else {
viewHolder = (HeaderViewHolder) view.getTag();
}
viewHolder.tvHeaderName.setText(getHeaderItem(position).getGroupName());
viewHolder.tvHeaderDate.setText(getHeaderItem(position).getTime());
return view;
}
#Override
public int getNumHeaders() {
return parents.size();
}
private static class HeaderViewHolder {
public TextView tvHeaderName;
public TextView tvHeaderDate;
}
Does anyone know how to solve this?
I think you should try what I say in this other question.
Basically, you have to replace your stickygridheaders.jar or your dependency in gradle with this other jar stickygridheaders.jar

You should try to use RecyclerView instead of ListView: https://developer.android.com/guide/topics/ui/layout/recyclerview
I have a recycler inside fragment in view pager.
The problem that it put likes on user accounts in UI randomly but in DB everything is fine.
In logs, I see that random is not influence on BD. So the bug is only in UI part. After the refresh of the list, it can appear again and after that disappear.
I would like to share code but I already don't have an I idea where the problem could be. It might be in adapter/refresh list listener / XML or any other places. Please let me know what part of the code you need and I will provide it. Maybe it is a bug of recycler as itself and I can't fix it.

I have to implement Horizontal scroll view for Child elements of ExpandableListView, now the child elements are shown in Vertical orientation.

I tried to change the item_group_child.xml LinearLayout orientation into horizontal, but no luck.
item_group.xml should be displayed in vertical way, it works, item_group_child.xml should be horizontal way, so the user can scroll child items horizontally. Is there any way to achieve this?
Not with a stock ExpandableListView. ExpandableListView is just a regular vertical ListView where the ExpandableListAdapter handles adding/removing the list items based on the group expand/collapse events.
If you want horizontally scrolling children, then you need to set up your ExpandableListAdapter so that each group has just one possible child view, and when that child view is created, it has a horizontal scrolling view that will contain all the group's children.
Yes, You can achieve this with CustomHorizontalListView. see this link. Just Implement it on your getChildView(). I am just customize my horizontalListView from above link. see following code:
This is your group_child_item.xml
<com.customlayout.HorizontalListView
android:id="#+id/horizontalListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/gray_d7"
android:padding="20dp"
xmlns:android="http://schemas.android.com/apk/res/android">
</com.customlayout.HorizontalListView>
Now inflate above xml into your getChildView():
#Override
public View getChildView(int groupPosition, int childPosition, boolean isLastchild, View convertView, ViewGroup parent)
{
ChildHolder childHolder = null;
if (convertView == null)
{
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.group_child_item, null, false);
childHolder = new ChildHolder();
childHolder.horizontalListView = (HorizontalListView) convertView.findViewById(R.id.horizontalListView);
convertView.setTag(childHolder);
}
else
{
childHolder = (ChildHolder) convertView.getTag();
}
HorizontalListViewAdapter horizontalListAdapter = new ModuleRoomHorizontalListAdapter(context, groupList, groupPosition);
ChildHolder.horizontalListView.setAdapter(horizontalListAdapter);
return convertView;
}
private static class ChildHolder
{
HorizontalListView horizontalListView;
}
Now implement your item_group_child.xml file for horizontalListViewChild and inflate in getView of HorizontalListAdapter
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/sharedCardImage"
android:layout_width="#dimen/image_card_xsmall_width"
android:layout_height="#dimen/image_card_xsmall_height"/>
<TextView
android:id="#+id/sharedBalAmount"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/sharedCardImage"
android:text="TextView"
android:textSize="#dimen/text_size_small"
android:textColor="#color/primary"
android:textAlignment="center"
android:gravity="center" />
</LinearLayout>
HorizontalListAdapter:
public class HorizontalListAdapter extends BaseAdapter
{
private Context mContext;
private ArrayList<Groups> mGroupListList;
private int mGroupPosition;
public HorizontalListAdapter(Context context, ArrayList<Groups> mGroupListList, int mGroupPosition)
{
this.mContext = context;
this.mGroupListList = mGroupListList;
this.mGroupPosition = mGroupPosition;
}
#Override
public int getCount()
{
return mGroupListList.get(mGroupPosition).getChildList().size();
}
#Override
public Object getItem(int position)
{
return mGroupListList.get(mGroupPosition).getChildList().get(position);
}
#Override
public long getItemId(int position)
{
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent)
{
ViewHolder viewHolder;
if (convertView == null)
{
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.item_group_child, null, false);
viewHolder = new ViewHolder();
convertView.setTag(viewHolder);
}
else
{
viewHolder = (ViewHolder) convertView.getTag();
}
// Implement Your code here what functionality you need.
return convertView;
}
private static class ViewHolder
{
TextView txtName;
}
}
Hope it helps you. If you have any issues let me know

Unfortunately, in this code only the original tweet shows up and the RecyclerView remains hidden for some reason. Could someone help me out how to position them in such a way that the RecyclerView is hidden above the screen and is visible only if you scroll up?
Decided to expand on my comment above with code. You can have multiple ViewHolders in one RecyclerView.Adapter, each can have different layouts (R.layout.original_tweet and R.layout.other_tweets here). getItemViewType() sets which viewholder to show. I didn't test or run the code so there might be a few bugs, but it should give you an idea at least.
public class MyAdapter
extends RecyclerView.Adapter {
private static final int ORIGINAL_TWEET = 0;
private static final int OTHER_TWEETS = 1;
private List<String> mTweets;
public MyAdapter(List<String> tweets) {
mTweets = tweets;
}
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view;
if (ORIGINAL_TWEET == viewType) {
view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.original_tweet, parent, false);
return new OriginalTweetViewHolder(view);
} else {
view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.other_tweets, parent, false);
return new OtherTweetsViewHolder(view);
}
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
if (holder instanceof OriginalTweetViewHolder) {
// populate with tweet data
} else if (holder instanceof OtherTweetsViewHolder) {
// populate with tweet data
}
}
#Override
public int getItemCount() {
return mTweets.size();
}
#Override
public int getItemViewType(int position) {
if (position == mTweets.size() - 1) {
// At bottom position
return ORIGINAL_TWEET;
} else {
return OTHER_TWEETS;
}
}
}
public static class OriginalTweetViewHolder extends RecyclerView.ViewHolder {
// ViewHolder fields
public OriginalTweetViewHolder(View view) {
super(view);
}
}
public static class OtherTweetsViewHolder extends RecyclerView.ViewHolder {
// ViewHolder fields
public OtherTweetsViewHolder(View view) {
super(view);
}
}

I will add something else if necessary. may have a library ready?
Change your ImageView by click gridview item:
gridView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
ViewHolder holder = (ViewHolder)view.getTag();
//set your new image here
holder.imageview.setImageResource(R.id.yourImage);
... ...
//maybe also update items content in 'position' if need
}
});
Hope this help!
