RecyclerView Horizontal Scroll Data changes randomly

RecyclerView Horizontal Scroll Data changes randomly - android

I am facing a issue in a horizontal recyclerview adapter.My adapter contains a imageview in postion 0 and remainings postion are empty.
When I do scroll from left to right, my images reappear from position 1 to 4 and 7.If I keeps on scrolling from left to right my imageview appears in all postion here is my adapter class.I have placed this Horizontal Recyclerview Adapter in a Vertical Recyclerview Adapter.
HomeBannerAdapter.Java
public class HomeBannerAdapter extends RecyclerView.Adapter {
private List<HomePageList> mHomepageList;
private Context mContext;
public HomeBannerAdapter(Context context, List<HomePageList> mHomepageList) {
this.mHomepageList = mHomepageList;
this.mContext = context;
}
#Override
public SingleItemRowHolder onCreateViewHolder(ViewGroup viewGroup, int position) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_single_card, viewGroup, false);
SingleItemRowHolder mh = new SingleItemRowHolder(v);
return mh;
}
#Override
public void onBindViewHolder(final SingleItemRowHolder holder, final int position) {
final HomePageList singleItem = mHomepageList.get(position);
holder.mTitle.setText(singleItem.getTitle());
if (!singleItem.getBannerUrl().isEmpty()) {
Glide.with(mContext).load(singleItem.getBannerUrl().get(0)).placeholder(R.drawable.placeholder).dontAnimate().into(holder.itemImage);
Log.e("Homebanner not empty", "url" + singleItem.getBannerUrl().toString() + "position" + position);
} else {
Log.e("Homebanner url empty", "url" + singleItem.getBannerUrl().toString() + "position" + position);
}
}
#Override
public int getItemCount() {
return (null != mHomepageList ? mHomepageList.size() : 0);
}
public class SingleItemRowHolder extends RecyclerView.ViewHolder {
public ImageView itemImage;
//int position = getAdapterPosition();
public TextView mTitle;
public HomePageList mHomePageList;
public SingleItemRowHolder(View view) {
super(view);
this.itemImage = (ImageView) view.findViewById(R.id.itemImage);
this.mTitle = (TextView) view.findViewById(R.id.tvTitle);
// mHomePageList = albumList.get(getPosition());
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(v.getContext(), mTitle.getText().toString() + " position " + getPosition() + "getAdapterPosition" + getAdapterPosition(), Toast.LENGTH_SHORT).show();
}
});
}
}
}

I think some of your items bannerUrls is empty. So if they're empty you do not set a default empty image with Glide or manually. Here i modified your code a little. I think this'll help.
#Override
public void onBindViewHolder(final SingleItemRowHolder holder, final int position) {
final HomePageList singleItem = mHomepageList.get(position);
holder.mTitle.setText(singleItem.getTitle());
if (!TextUtils.isEmpty(singleItem.getBannerUrl())) {
Glide.with(mContext).load(singleItem.getBannerUrl().get(0)).placeholder(R.drawable.placeholder).dontAnimate().into(holder.itemImage);
Log.e("Homebanner not empty", "url" + singleItem.getBannerUrl().toString() + "position" + position);
} else {
holder.itemImage.setImageResource(R.drawable.your_place_holder_for_empty_url);
}
}
Note: Also it's a better choice to use TextUtils.isEmpty(string) to instead of string.isEmpty() to avoid Null Pointer Exception.
Edit:
Also you can let Glide to put placeholder to your ImageView by removing the if statement.
if (!TextUtils.isEmpty(singleItem.getBannerUrl()))
I think this solution'll work you for too. If you choose this way do not forget to set an empty image to Glide for your empty or null urls.

RecyclerView with different layouts

when i use this
#Override
public int getItemViewType(int position) {
return position;
}
my RecyclerView work without problem
now i want to use multi layout on it i use this
#Override
public int getItemViewType(int position) {
int type = -1;
if(mMessages.get(position).getDir().equals("left")) type = 1;
else if(mMessages.get(position).getDir().equals("right")) type = 0;
else if(mMessages.get(position).getDir().equals("typing")) type = 2;
return type;
//return position;
}
the problem when i used it's and scroll to top and back to bottom or just scrolling
its reorder item in RecyclerView like make the first item on it the last one or on middle or every where not i the correct position
just if i back to the first code of getItemViewType its work without
problem but i cant use multi layout
my full code
public class MessageAdapter1 extends RecyclerView.Adapter<MessageAdapter1.ViewHolder> {
private List<MessageList> mMessages;
private int[] mUsernameColors;
private Context context;
public MessageAdapter1(Context context, List<MessageList> messages) {
mMessages = messages;
this.context = context;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
int layout = -1;
switch (viewType) {
case 0:
layout = R.layout.right_message;
break;
case 1:
layout = R.layout.left_message;
break;
case 2:
layout = R.layout.message_left;
break;
}
View v = LayoutInflater.from(parent.getContext()).inflate(layout , parent, false);
return new ViewHolder(v);
}
#Override
public void onBindViewHolder(ViewHolder viewHolder, int position) {
MessageList message = mMessages.get(position);
//viewHolder.setMessage(message.getMessage());
//viewHolder.setUsername(message.getUsername());
viewHolder.setGroupMessage(message);
}
#Override
public int getItemCount() {
return mMessages.size();
}
#Override
public int getItemViewType(int position) {
int type = -1;
if(mMessages.get(position).getDir().equals("left")) type = 1;
else if(mMessages.get(position).getDir().equals("right")) type = 0;
else if(mMessages.get(position).getDir().equals("typing")) type = 2;
return type;
//return position;
}
public class ViewHolder extends RecyclerView.ViewHolder {
private LinearLayout groupMessage;
//private ImageView typing;
public ViewHolder(View itemView) {
super(itemView);
groupMessage = (LinearLayout)itemView.findViewById(R.id.messages);
}
public void setGroupMessage(MessageList m) {
if (null == groupMessage) return;
int i = 0;
if(m.getMessageStatus() == false){
m.setMessageStatus(true);
for (String message : m.getMessageList()) {
//TextView text = new TextView(activity);
TextView text = new MyTextView(context);
LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
p.setMargins(0, 0, 0, 2);
if (m.getDir().equals("left")) {
text.setTextColor(Color.BLACK);
p.gravity = Gravity.LEFT;
if(m.getMessageList().size() == 1){
text.setBackgroundResource(R.drawable.message_left_default);
}
else if (i == 0) {
text.setBackgroundResource(R.drawable.message_left_first);
} else if (i + 1 == m.getMessageList().size()) {
text.setBackgroundResource(R.drawable.message_left_last);
} else {
text.setBackgroundResource(R.drawable.message_left);
}
} else{
p.gravity = Gravity.RIGHT;
text.setTextColor(Color.WHITE);
if(m.getMessageList().size() == 1){
text.setBackgroundResource(R.drawable.message_right_default);
}
else if (i == 0) {
text.setBackgroundResource(R.drawable.message_right_first);
} else if (i + 1 == m.getMessageList().size()) {
text.setBackgroundResource(R.drawable.message_right_last);
} else {
text.setBackgroundResource(R.drawable.message_right);
}
}
text.setLayoutParams(p);
text.setText(message);
text.setPadding(8, 8, 8, 8);
text.setTextSize(18f);
//text.setTextAppearance(context, android.R.style.TextAppearance_Large);
groupMessage.addView(text);
i++;
}
}
}
}
}

I solve it by remove
int type = -1;
if(mMessages.get(position).getDir().equals("left")) type = 1;
else if(mMessages.get(position).getDir().equals("right")) type = 0;
else if(mMessages.get(position).getDir().equals("typing")) type = 2;
return type;
from
getItemViewType
and return position
and put the first code
int type = -1;
if(mMessages.get(position).getDir().equals("left")) type = 1;
else if(mMessages.get(position).getDir().equals("right")) type = 0;
else if(mMessages.get(position).getDir().equals("typing")) type = 2;
return type;
in onCreateViewHolder and use viewType as the current position

AdapterView of Gridview is not refreshing, it is showing weird response (Some times it is refreshing some times not)

I am setting the adapter of gridview on a fragment. this fragment is attached on the layout of view pager and viewpager is attached in an activity.
I have checked my arraylist data is refreshed but view is not refreshing.
My code is:
Setting the adapter in the onCreate of Activity::
for(ArrayList<Item> newLst : updateList){
newPropertySubList.add(newLst);
}
Log.e("newPropertySubList","newPropertySubList"+newPropertySubList.size());
adapter = new PropertyPagerAdapetr(getSupportFragmentManager());
//propertyViewPager.setAdapter(adapter);
adapter.notifyChangeInPosition(1);
propertyViewPager.setAdapter(adapter);
adapter.notifyDataSetChanged();
mIndicator.setViewPager(propertyViewPager);
PropertyPagerAdapetr is: in this code section GridviewFragment new instance is created when adapter is setting.
public class PropertyPagerAdapetr extends FragmentPagerAdapter {
private long baseId = 0;
public PropertyPagerAdapetr(FragmentManager fm) {
super(fm);

Could be you're mixing GridLayout and GridView. They are different entities.
In setUpGridLayout() you are inflating a grid_view_imageviewitem and adding it to a GridLayout, not GridView.

i have solve the issue using
Handler disconnectHandler = new Handler() {
public void handleMessage(Message msg) {
}
};
Runnable disconnectCallback = new Runnable() {
#Override
public void run() {
/////////// load data from here ////
}
}
};
disconnectHandler.postDelayed(disconnectCallback, 1000);*

I don't know what's causing the problem. I can use the same method on my fragments but in this adapter it's not working.

Change
adapter = new AdapterPOI(getApplicationContext(), ....)
to
adapter = new AdapterPOI(this, ....)
in the code where you call the adapter's constructor. You get the error because getApplicationContext() cannot be casted to an ActivityCategorySelected. That's an Application context; whereas the adapter is expecting an Activity's context.

change color of listview row

Let me explain in brief.
I have 2 Fragments:
1) Fragment A where user enters some text. here i have also defined 5 buttons each of different colors. From here, the entered text is added to database.
2) Fragment B which has a listview which populates data from that database using customadapter when user click the "Save" button in Fragment A.
Everything is working fine. Data is being saved, loaded into Listview and all. Now remember those 5 buttons with 5 different colors?
What I Want is that suppose while adding data in Fragment A, user selected button with color "Orange" suppose, then the row that will be inflated in getView() method of adapter should also have its background orange.
(Something ike Google Keep)
Is that possible?

It is possible.
Pass that selected color to Fragment B on button click.
Pass that color as an argument to the adapter constructor from fragment B.
Now you know the color inside the adapter.
In getView() function of the adapter, based on the color, change the background color of the inflated view. using : view.setBackgroundColor(color);
See the sample here : https://github.com/vishalvijay/SampleColorListView

As far as I think all you have to do is to save color hex code also in your database alongwith your text. It is more simple and scaleable. when you fetch text from database, you should also fetch the color in the same ArrayList of custom objects and then in getView method of your adapter, just apply the corresponding Hex color code to your convertView.

Android AlphabetIndexer English and Hebrew(Unicode) togather

Following is my listview adapter classes using AlphabetIndexer.
It does not work when I add unicode chars (for hebrew) togather with the english.
I get exception in: getSectionForPosition. getting to index -1....
Tries it with 2 entries in the DB - 1 starting with hebrew char (unicode) and one with english. The first char for AlphabetIndexer was the unicode char.
Really really need help in this one....
