My adapter list is refreshing on broadcast receiver .
Everything is working fine if adapter list size is greater than 1 , means if my recyclerview has already one row shwoing then list refreshing just fine . But if list size goes from 0 to 1 then my adapter notify dataset Changed stop working . No data shows on recyclerview. I don't know why it is not working .
Recyclerview Class:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
v = inflater.inflate(R.layout.job_recyclerview, container, false);
getActivity());
initialise(v);
init();
showNoTaskMessage();
new loadListTask().executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
mMyBroadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// Here you can refresh your listview or other UI
SlidingTab.slidingTab.getTabAt(0).setText("New (" + SingleTon.getInstance().getNewjob() + ")");
SlidingTab.slidingTab.getTabAt(1).setText("In Progress (" + SingleTon.getInstance().getInprogressjob() + ")");;
SlidingTab.slidingTab.getTabAt(2).setText("Completed (" + SingleTon.getInstance().getCompletedjob() + ")");
}
};
try {
IntentFilter filter = new IntentFilter("newJob");
LocalBroadcastManager.getInstance(context).registerReceiver(mMyBroadcastReceiver,
filter);
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return v;
}
Adapter class :
public JobAdapter(ArrayList<Info> myDataset, Context context) {
this.mDataset = myDataset;
this.mAct = context;
}
public void addApplications(ArrayList<Info> candidates) {
if (this.filterList == null) {
filterList = new ArrayList<>();
}
this.mDataset.clear();
this.mDataset.addAll(candidates);
this.filterList.addAll(mDataset);
this.notifyItemRangeInserted(0, candidates.size() - 1);
}
public void clearApplications() {
int size = this.mDataset.size();
if (size > 0) {
for (int i = 0; i < size; i++) {
mDataset.remove(0);
filterList.remove(0);
}
this.notifyItemRangeRemoved(0, size);
}
}
@Override
public int getItemViewType(int position) {
return VIEW_NORMAL;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.single_job_card, parent, false);
ViewHolder fh = new ViewHolder(v);
return fh;
}
@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
// holder.jobPhone.setText(mDataset.get(position).mobileNo);
holder.jobNumber.setText(mDataset.get(position).jobNumber);
holder.jobTime.setText(mDataset.get(position).time);
holder.jobAddress.setText(mDataset.get(position).address);
// holder.jobInstructionText.setText(mDataset.get(position).spclInstruction);
if (mDataset.get(position).jobStatus != null && mDataset.get(position).jobStatus.equalsIgnoreCase("Completed")) {
holder.endsat.setText("Submitted at");
holder.jobTime.setText(mDataset.get(position).completedOnString);
holder.jobTimeLeft.setVisibility(View.INVISIBLE);
holder.timerImage.setVisibility(View.INVISIBLE);
} else {
if (mDataset.get(position).status.equalsIgnoreCase("Active")) {
holder.jobTimeLeft.setText(mDataset.get(position).appointmentTime);
} else {
holder.jobTimeLeft.setText("-" + mDataset.get(position).appointmentTime);
}
}
holder.jobLayout1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
SingleTon.getInstance().setWorkDescHolder(mDataset.get(position).descHolder);
FragmentManager fragmentManager = ((FragmentActivity) mAct).getSupportFragmentManager();
FragmentTransaction ft = ((FragmentActivity) mAct).getSupportFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.glide_fragment_horizontal_in, R.anim.glide_fragment_horizontal_out);
ft.replace(R.id.content_frame1, new DetailsFragment(), "persondetails");
ft.addToBackStack("persondetails");
// Start the animated transition.
ft.commit();
}
});
}
@Override
public int getItemCount() {
return mDataset.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
private TextView jobNumber, jobTimeLeft, jobStatus, jobAddress, jobEmail, jobPhone, timeTimer, jobInstructionText, jobTime, endsat;
private ImageView timerImage;
private FrameLayout frameLayout;
private CardView cardView;
private LayoutRipple jobLayout1;
public ViewHolder(View v) {
super(v);
this.jobNumber = (TextView) v.findViewById(R.id.job_number);
this.jobTime = (TextView) v.findViewById(R.id.job_time);
this.jobTimeLeft = (TextView) v.findViewById(R.id.job_timertext);
this.timerImage = (ImageView) v.findViewById(R.id.timerimage);
this.cardView = (CardView) v.findViewById(R.id.card_view);
// this.jobStatus = (TextView) v.findViewById(R.id.job_status);
this.jobAddress = (TextView) v.findViewById(R.id.job_addresstext);
// this.jobInstructionText = (TextView) v.findViewById(R.id.instruction_text);

this.jobLayout1 = (LayoutRipple) v.findViewById(R.id.cardLayout1);
this.endsat = (AppCompatTextView) v.findViewById(R.id.endsat);
this.jobNumber.setTypeface(Utils.RegularTypeface(mAct));
this.jobAddress.setTypeface(Utils.RegularTypeface(mAct));
this.jobTimeLeft.setTypeface(Utils.RegularTypeface(mAct));
this.jobTime.setTypeface(Utils.RegularTypeface(mAct));
}
}
}
Please help me finding the bug or some other approach . Thanks
Call the data loading task inside the onReceive() of BroadcastReceiver
mMyBroadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// Here you can refresh your listview or other UI
new loadListTask().executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
SlidingTab.slidingTab.getTabAt(0).setText("New (" + SingleTon.getInstance().getNewjob() + ")");
SlidingTab.slidingTab.getTabAt(1).setText("In Progress (" + SingleTon.getInstance().getInprogressjob() + ")");;
SlidingTab.slidingTab.getTabAt(2).setText("Completed (" + SingleTon.getInstance().getCompletedjob() + ")");
}
};
And also do following changes in your Adapter class.
public void addApplications(ArrayList<Info> candidates) {
if (this.filterList == null) {
filterList = new ArrayList<>();
}
this.mDataset.clear();
this.mDataset.addAll(candidates);
this.filterList.addAll(mDataset);
this.notifyItemRangeInserted(0, candidates.size());
}
public void clearApplications() {
int size = this.mDataset.size();
if (size > 0) {
for (int i = 0; i < size; i++) {
mDataset.remove(i);
filterList.remove(i);
}
this.notifyItemRangeRemoved(0, size);
}
}
Hope that works!
