recyclerview items not scrolling?
Question
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.
