Get String in list in adapter (gson) - json

Question

I have a problem with my adapter. I already succeeded to display some informations from my JSON (codeLieu and libelle) that looks like this:
[
{
"codeLieu": "OTAG",
"libelle": "50 Otages",
"distance": null,
"ligne": [
{
"numLigne": "2"
},
{
"numLigne": "C2"
},
{
"numLigne": "12"
},
{
"numLigne": "23"
}
]
},
...
]
Here is my model:
package material.romain.com.projentreprise.Adapter;
import com.google.gson.annotations.SerializedName;
import java.io.Serializable;
import java.util.List;
public class Response implements Serializable{
private String codeLieu;
private String libelle;
private String distance;
private List<LigneEntities> ligne;
public String getCode() {
return codeLieu;
}
public void setCode(String codeLieu) {
this.codeLieu = codeLieu;
}
public String getLibelle() {
return libelle;
}
public void setLibelle(String libelle) {
this.libelle = libelle;
}
public String getDistance() {
return distance;
}
public void setDistance(String distance) {
this.distance = distance;
}
public List<LigneEntities> getLigne() {return ligne;}
public void setLigne(List<LigneEntities> ligne) {
this.ligne = ligne;
}
public static class LigneEntities {
private String numLigne;
public String getLigne() {
return numLigne;
}
public void setLigne(String numLigne) {
this.numLigne = numLigne;
}
}
}
And finally this is my adapter :
package material.romain.com.projentreprise.Adapter;
import android.content.Context;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.graphics.drawable.Drawable;
import android.graphics.drawable.LayerDrawable;
import android.support.v4.content.ContextCompat;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Filter;
import android.widget.Filterable;
import android.widget.TextView;
import com.mikepenz.fontawesome_typeface_library.FontAwesome;
import com.mikepenz.iconics.IconicsDrawable;
import java.util.ArrayList;
import de.hdodenhof.circleimageview.CircleImageView;
import material.romain.com.projentreprise.R;
import material.romain.com.projentreprise.Util.CircularTextView;
import material.romain.com.projentreprise.Util.ColorLigne;
public class ListAdapter extends BaseAdapter implements Filterable {
private ArrayList<Response> arret;
private Context context;
private LayoutInflater inflater;
private MyFilter mFilter;
private ArrayList<Response> mSearchArret;
public ListAdapter(Context mContext, ArrayList<Response> mArretItem) {
this.context = mContext;
this.arret = mArretItem;
this.mSearchArret = mArretItem;
getFilter();
}
#Override
public int getCount() {
return mSearchArret.size();
}
#Override
public Object getItem(int position) {
return mSearchArret.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
Response item = (Response) getItem(position);
ColorLigne.ViewHolder holder = null;
if (convertView == null) {
holder = new ColorLigne.ViewHolder();
inflater = LayoutInflater.from(context);
convertView = inflater.inflate(R.layout.each_list_item, parent, false);
holder.circleImage = (CircleImageView) convertView.findViewById(R.id.circleView);
holder.textArret = (TextView) convertView.findViewById(R.id.tvListArret);
holder.circle = (CircularTextView) convertView.findViewById(R.id.tvArretColor);
convertView.setTag(holder);
} else {
holder = (ColorLigne.ViewHolder) convertView.getTag();
}
Drawable color = new ColorDrawable(ContextCompat.getColor(context, R.color.tanVert));
Drawable image = new IconicsDrawable(context).icon(FontAwesome.Icon.faw_bus).color(Color.WHITE).sizeDp(48).paddingDp(10);
LayerDrawable ld = new LayerDrawable(new Drawable[]{color, image});
holder.circleImage.setImageDrawable(ld);
holder.textArret.setText(item.getLibelle());
return convertView;
}
#Override
public Filter getFilter() {
if (mFilter == null) {
mFilter = new MyFilter();
}
return mFilter;
}
class MyFilter extends Filter {
#Override
protected FilterResults performFiltering(CharSequence prefix) {
FilterResults results = new FilterResults();
if (prefix != null && prefix.length() > 0) {
ArrayList<Response> tempList = new ArrayList<>();
for (Response value : arret) {
if (value.getLibelle().toLowerCase().contains(prefix.toString().toLowerCase())) {
tempList.add(value);
}
}
results.count = tempList.size();
results.values = tempList;
} else {
results.count = arret.size();
results.values = arret;
}
return results;
}
#Override
protected void publishResults(CharSequence constraint, FilterResults results) {
try {
mSearchArret = (ArrayList<Response>) results.values;
if (results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
And I would like to get strings from "ligne" but it's in a list and I don't know how to access it. My goal is to put the strings into a circleTextView.
Edit:
I tried this in getView method
Response item = getItem(position);
for(Response value: arret){
value = item;
String ligneItem = value.getLigne().toString();
ColorLigne.setColorLigne(ligneItem, holder, context);
holder.circle.setText(ligneItem);
holder.circle.setStrokeWidth(0);
}

Answer 1

Add below method to your Response.java
public String getItems() {
StringBuilder builder = new StringBuilder();
for (LigneEntities entity : getLigne()) { //loop through every item from the list
builder.append(entity.getLigne() + ","); //add to StringBuilder
}
builder.replace(builder.length() - 1, builder.length(), "");//remove last ,(semicolon)
return builder.toString();
}
setting to your CircleTextView
holder.circle.setText(item.getItems());
