Recyclerview not all data is displayed

Recyclerview not all data is displayed - android

hi I am trying to display data in a recyclerview in android by parsing a json from mysql database. But it keeps displaying just some of the data and I can't seem to find the problem.Any help will be greatly appreciated.
This is the adapter:
public class Adapter extends RecyclerView.Adapter<Adapter.MyViewHolder> {
List<Course> data;
private Context context;
public Adapter(Context context,List<Course> data){
this.data=data;
this.context=context;
}
#NonNull
#Override
public MyViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view=LayoutInflater.from(parent.getContext()).inflate(R.layout.course_list,parent,false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int position) {
DecimalFormat form = new DecimalFormat("0.00");
Course current=data.get(position);
holder.tCoursecode.setText(current.getmCoursecode());
holder.tCoursetitle.setText(current.getmCoursetitle());
holder.tCredit.setText(String.valueOf(current.getmCredit()));
holder.tMarks.setText(form.format (current.getmMarks()));
holder.tGrade.setText(current.getmGrade());
}
#Override
public int getItemCount() {
return data.size();
}
class MyViewHolder extends RecyclerView.ViewHolder {
TextView tCoursecode;
TextView tCoursetitle;
TextView tCredit;
TextView tMarks;
TextView tGrade;
public MyViewHolder(View itemView) {
super(itemView);
tCoursecode=itemView.findViewById(R.id.tcc);
tCoursetitle=itemView.findViewById(R.id.tct);
tCredit=itemView.findViewById(R.id.tc);
tMarks=itemView.findViewById(R.id.tm);
tGrade=itemView.findViewById(R.id.tg);
}
}
this the layout:
<LinearLayout

My code for RecyclerView Adapter:
package org.poolshot.poolshotacademy;
import android.content.Context;
import android.content.SharedPreferences;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import java.util.List;
public class My_DrillGraph_RecyclerView_Adapter extends RecyclerView.Adapter<My_DrillGraph_RecyclerView_Adapter.MyHolder> {
SharedPreferences defaultPreferencesSettings;
private Context myRCAContext;
private List<String> myDrillGraphDates;
private List<Integer> myDrillGraphSkill;
// constructor
public My_DrillGraph_RecyclerView_Adapter(Context applicationContext, List<String> mDrillGraphDates, List<Integer> mDrillGraphSkill) {
this.myRCAContext = applicationContext;
this.myDrillGraphDates = mDrillGraphDates;
this.myDrillGraphSkill = mDrillGraphSkill;
}
#NonNull
#Override
public MyHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int position) {
View layout = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.drill_graph_single_column,null);
MyHolder myHolder = new MyHolder(layout);
return myHolder;
}
#Override
public void onBindViewHolder(#NonNull final MyHolder viewHolder, final int position) {
String skill = myDrillGraphSkill.get(position).toString();
// set color for buttons
viewHolder.btnDate.setBackground(myRCAContext.getResources().getDrawable(R.drawable.custom_btn_grey));
viewHolder.btnSkill.setTextColor(myRCAContext.getResources().getColor(R.color.white));
// set text for buttons
viewHolder.btnDate.setText(myDrillGraphDates.get(position));
viewHolder.btnSkill.setText(skill);
}
#Override
public int getItemCount() {
return myDrillGraphDates.size();
}
public static class MyHolder extends RecyclerView.ViewHolder {
Button btnDate;
Button btnSkill;
public MyHolder(View itemView) {
super(itemView);
btnDate = itemView.findViewById(R.id.btnDate);
btnSkill = itemView.findViewById(R.id.btnSkill);
}
}
}

This is my solution :
I changed the code of the class MyHolder as :
public static class MyHolder extends RecyclerView.ViewHolder {
Button btnDate;
Button btnSkill;
public MyHolder(View itemView) {
super(itemView);
btnDate = itemView.findViewById(R.id.btnDate);
btnSkill = itemView.findViewById(R.id.btnSkill);
LinearLayout.LayoutParams layoutParams =
new LinearLayout.LayoutParams(android.view.ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.MATCH_PARENT);
layoutParams.gravity = Gravity.BOTTOM;
itemView.setLayoutParams(layoutParams);
}
}

recyclerview items not scrolling?

I am making android cv app and I have implemented RecyclerView but items not scrolling even though, I have used RecyclerViewLayout Manager.
below my SkillsAdapter.class
public class SkillsAdapter extends RecyclerView.Adapter {
public List skillList;
public Context context;
public SkillsAdapter(List<Skill> skillList, Context context) {
this.skillList = skillList;
this.context = context;
}
#NonNull
#Override
public SkillsAdapter.ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(context)
.inflate(R.layout.skills_item, parent, false); // change
return new SkillsAdapter.ViewHolder(itemView);
}
#Override
public void onBindViewHolder(#NonNull SkillsAdapter.ViewHolder holder, int position) {
Skill skill = skillList.get(position);
holder.programming.setText(skill.getProgramming());
holder.framework.setText(skill.getFrameworkLibraries());
holder.architecture.setText(skill.getAndroidArchitectureComponents());
holder.software.setText(skill.getSoftwareMethodologies());
holder.ide.setText(skill.getIDES());
}
#Override
public int getItemCount() {
return skillList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView programming, framework, architecture, software, ide;
public ViewHolder(View view) {
super(view);
programming= (TextView) view.findViewById(R.id.programming);
framework = (TextView) view.findViewById(R.id.framework);
architecture = (TextView) view.findViewById(R.id.architecture);
software = (TextView) view.findViewById(R.id.software);
ide = (TextView)view.findViewById(R.id.ide);
}
}
}
below my SkillsItem.java class
public class SkillItem extends AppCompatActivity {
private SkillsAdapter skillsAdapter;
public List<Skill> skillList;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.skills);
KitabInterface kitabInterface = ApiClient.getApiService();
Call<KitabSawti> call = kitabInterface.getSkills();
call.enqueue(new Callback<KitabSawti>() {
#Override
public void onResponse(Call<KitabSawti> call, Response<KitabSawti> response) {
skillList= response.body().getSkills();
RecyclerView recyclerView = findViewById(R.id.recyclerView);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getApplicationContext(), LinearLayoutManager.VERTICAL, false);
recyclerView.setLayoutManager(linearLayoutManager);
skillsAdapter = new SkillsAdapter( skillList, SkillItem.this); // changes
recyclerView.setAdapter(skillsAdapter);
}
#Override
public void onFailure(Call<KitabSawti> call, Throwable t) {
}
});

The problem is, that the root layout of your item (the root LinearLayout at skills_items.xml) has height of match_parent. This messes up the way RecyclerView does the scrolling event calculations.
Also, it is generally advised against using wrap_content for height or width of the root layout for an activity and for wrap_content for height (if scroll is vertical) or width (if scroll is horizontal) of RecyclerView or ListView.

you have to add this functionality in your adapter,
#Override
public View getView(int position, View convertView, ViewGroup parent) {
//ur other codes.....
//
//
if(crossButtonPress){
holder.imageView.setImageResource(R.drawable.cross);
}else{
holder.imageView.setImageResource(R.drawable.default_ic);
}
}
In addition, in you actual button's onClick,
crossButtonPress = true;
adapter.notifyDatasetChanged();

ListView Items changed automatically in Fragment android

when I scroll the listview the items changed automatically, in other word an item override other item's view like : when I click on favorite button other items has been changed like this
example:
the item that I clicked
I didn't click on this item
here is my code :
CustomListAdapter.java :
public class CustomListAdapter extends BaseAdapter {
private Context context;
LayoutInflater inflater;
boolean isVoter;
public CustomListAdapter(Context c ) {
this.context = c;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null){
LayoutInflater layoutInflater = (LayoutInflater)context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(R.layout.date_view,null);
viewHolder = new ViewHolder();
viewHolder.vote = (ImageButton) convertView.findViewById(R.id.vote);
}else {
viewHolder = (ViewHolder)convertView.getTag();
}
isVoter = newsItemArray.get(position).isVoter();
viewHolder.vote.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (!Utility.isNetworkAvailable(context))
Toast.makeText(context, R.string.no_network, Toast.LENGTH_LONG).show();
else
voteBtn( position);
}});
return convertView;
}
public void voteBtn(int position){
if ( !isVoter ) {
viewHolder.vote.setImageResource(R.drawable.button_pressed);
}
else{
viewHolder.vote.setImageResource(R.drawable.button_normal);
}
isVoter = !isVoter;
}
}
private class ViewHolder{
ImageButton vote ;
}
#Override
public int getCount() {
return newsItemArray.size();
}
#Override
public Object getItem(int position) {
return newsItemArray.get(position).getTitle();
}
#Override
public long getItemId(int position) {
return position;
}
}

isVoter and viewHolder should not be global variables within the Adapter. Meaning, you are not actually changing whatever member is returned by newsItemArray.get(position).isVoter()
Try adding the position to the ViewHolder object. Then pass the ViewHolder object into the constructor of the viewHolder.vote.setOnClickListener. Within the OnClickListener you can then call
isVoter = newsItemArray.get(viewHolder.position).isVoter();
newsItemArray.get(viewHolder.position).setVoter(!isVoter);

You need to create your onitemclick because RecyclerView does not have a OnItemClick like Listview, i have an example in Github check it.
