I bind ListView with multiple rows select function. I bind the list view with custom adapter. But problem while I want to get the list from Adapter an error is shown - "Could not execute method of the activity". I also set the getter property in the adapter. But while I call the getter method it throw error.
Please suggest some solution so that I can solve it.
Adapter:
public class CityAdapter extends BaseAdapter {
private Context context;
public List<CityModle.City> citys;
LayoutInflater inflater;
private CitySelectInterface listener;
private ArrayList<CityModle.City> arraylist;
public List<CityModle.City> getCitys() {
return citys;
}
public CityAdapter(Context context, List<CityModle.City> citys, CitySelectInterface listener) {
this.context = context;
this.citys = citys;
this.listener = listener;
inflater = LayoutInflater.from(this.context);
this.arraylist = new ArrayList<CityModle.City>();
this.arraylist.addAll(citys);
}
@Override
public int getCount() {
Log.v("getCountJit",this.citys.size()+"") ;
return this.citys.size();
}
@Override
public CityModle.City getItem(int i) {
return this.citys.get(i);
}
@Override
public long getItemId(int i) {
return 0;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
final MyViewHolder mViewHolder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.cityrowlayout, parent, false);
mViewHolder = new MyViewHolder(convertView);
convertView.setTag(mViewHolder);
} else {
mViewHolder = (MyViewHolder) convertView.getTag();
}
mViewHolder.tvTitle.setText(this.citys.get(position).getName());
if(this.citys.get(position).isCheckBox() == true)
{
mViewHolder.imageCheck.setVisibility(View.VISIBLE);
} else {
mViewHolder.imageCheck.setVisibility(View.GONE);
}
convertView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mViewHolder.imageCheck.setVisibility(View.GONE);
Toast.makeText(context, "testClick"+position, Toast.LENGTH_SHORT).show();
listener.cityTableRowClick(String.valueOf(position));
int setView = 0;boolean setchk=false;
if(mViewHolder.imageCheck.getVisibility()== View.GONE) {
Toast.makeText(context, "GONE", Toast.LENGTH_SHORT).show();
mViewHolder.imageCheck.setVisibility(View.VISIBLE);
setchk = true;
} else {
Toast.makeText(context, "VISIBLE", Toast.LENGTH_SHORT).show();
mViewHolder.imageCheck.setVisibility(View.GONE);
setchk = false;
}
citys.get(position).setCheckBox(setchk);
}
});
return convertView;
}
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
citys.clear();
if (charText.length() == 0) {
citys.addAll(arraylist);
} else {
for (CityModle.City wp : arraylist) {
if (wp.getName().toLowerCase(Locale.getDefault())
.contains(charText)) {
citys.add(wp);
}
}
}
notifyDataSetChanged();
}
private class MyViewHolder {
TextView tvTitle;
ImageView imageCheck;
public MyViewHolder(View item) {
tvTitle = (TextView) item.findViewById(R.id.nameOfCountry);
imageCheck = (ImageView) item.findViewById(R.id.imageCheck);
}
}
}
In Activity:
public void closerlviewpopup(View view) {
List<CityModle.City> cts = cityAdapter.getCitys();
Toast.makeText(this, cts.size(), Toast.LENGTH_SHORT).show();
//cts.size() throws an error Could not execute method of the activity
}

Indicates problem with some String resource which you did not provide. cts.size() is returning int where the Toast.makeText function requires a String. You need to change the line as follows.
Toast.makeText(this, cts.size().toString(), Toast.LENGTH_SHORT).show();
