Recyclerview doesn't show or scroll in fragment

I have found some questions regarding this issue here but none of them helped to solve my problem. Recycler view works fine but there is issue in lollipop version. It works perfectly in an activity but doesn't show or scroll when used inside fragment. My fragment screen appears blank but the tap listeners in recycler view's adapter is working. When I migrated my fragment code to an activity, it worked fine. I am using 28.0.0 Here is my xml code.

God Damn! After being stuck in this issue for 2 whole days, I finally found the solution. It was because I was using FragmentTransaction.TRANSIT_FRAGMENT_FADE when adding fragment inside activity. Removing the transition solved my problem

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;

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.

Use compile 'com.android.support:cardview-v7:25.0.0' to get the CardView.
this is the sample output.

use ListView or RecyclerView with your custom list item which will contain image buttons and custom adapter

Instead of px use dp it´s much better!
If you want a fixed list, your XML is correct, but if you want a dynamic list, you should use ListView or RecycleView , as the others users said.
The weight in your LinearLayout is wrong, weight should be used when you desires your screen to fit in every screen, no matter the size ( and you will need to "distribute" your weigth throught the children´s).
To make your screen similar to the first image, you need to set a background in your second LinearLayout

Okey this a recyclerview for what you want,
public class MainPageAdapter extends RecyclerView.Adapter<MainPageAdapter.ViewHolder> {
private #DrawableRes int[] iconDrawables;
private String[] texts;
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
final View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.item, parent, false);
return new ViewHolder(v);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.img_lockIcon.setImageResource(iconDrawables[position]);
holder.txt_whatever.setText(texts[position]);
}
#Override
public int getItemCount() {
return iconDrawables != null ? iconDrawables.length : 0;
}
public void setData(#DrawableRes int[] iconDrawables, String[] texts){
this.iconDrawables = iconDrawables;
this.texts = texts;
this.notifyDataSetChanged();
}
public static class ViewHolder extends RecyclerView.ViewHolder {
ImageView img_icon;
TextView txt_whatever;
ImageView img_lockIcon;
public ViewHolder(View itemView) {
super(itemView);
img_icon = itemView.findViewById(R.id.item_img_icon);
txt_whatever = itemView.findViewById(R.id.item_txt_whatever);
img_lockIcon = itemView.findViewById(R.id.item_img_lockIcon);
}
}
}
this is R.layout.item,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="8dp"

<ImageView
android:id="#+id/item_img_lockIcon"

android:layout_height="40dp"

</LinearLayout>
and below is MainActivity layout,
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardCornerRadius="0dp"
app:cardElevation="0dp"
app:cardBackgroundColor="#color/colorPrimary"
android:layout_margin="8dp">
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:listitem="#layout/item"/>
</android.support.v7.widget.CardView>
</FrameLayout>
and below is MainActivity,
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RecyclerView recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
MainPageAdapter adapter = new MainPageAdapter();
recyclerView.setAdapter(adapter);
//Set your data
//adapter.setData();
}
}
You can change color as you want and also notify that ı used two different arrays for adapter but you can use pojo classes also. Hope this helps you.

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

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);
