I am trying to get database from SQLite database and trying to populate the ListView and also adding data in ArrayList . The ListView is populated nicely but problem is ArrayList is not populated nicely.
Suppose I have data in database like: A B C D E F G H I J K L M N ........ My ListView Showing data in this way. But ArrayList add the data this way: A B C D E F A B C D E F G H ......
That means my ArrayList takes first 6 value then repeat it and then it takes next 6 value then again repeat it ..... . That means When I click item "H" from list view the ArrayList shows me "B". I don't know why it is happening?
My Code, CustomList which extends CursorAdapter
import java.util.ArrayList;
import android.content.Context;
import android.database.Cursor;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CheckBox;
import android.widget.CursorAdapter;
import android.widget.TextView;
public class CustomList extends CursorAdapter {
CheckBox favoriteBox;
TextView cityName, countryName;
ArrayList<String> city_name;
ArrayList<String> country_name;
ArrayList<String> country_short;
ArrayList<CheckBox> check_box;
public CustomList(Context context, Cursor c, ArrayList<String> city_name,
ArrayList<String> country_name, ArrayList<String> country_short,
ArrayList<CheckBox> check_box) {
super(context, c, 0);
this.city_name = city_name;
this.country_name = country_name;
this.country_short = country_short;
this.check_box = check_box;
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View retView = inflater.inflate(R.layout.all_city_list, parent, false);
return retView;
}
@Override
public void bindView(final View view, Context context, Cursor cursor) {
cityName = (TextView) view.findViewById(R.id.cityName);
String cityS = cursor.getString(cursor.getColumnIndex("city_name"));
cityName.setText(cityS);
city_name.add(cityS);//adding value to ArrayList<String>
countryName = (TextView) view.findViewById(R.id.countryName);
String conS = cursor.getString(cursor.getColumnIndex("country_name"));
countryName.setText(conS);
country_name.add(conS);//adding value to ArrayList<String>
country_short.add(""
+ cursor.getString(cursor.getColumnIndex("country_short")));//adding value to ArrayList<String>
favoriteBox = (CheckBox) view.findViewById(R.id.favoriteCheckBox);
check_box.add(favoriteBox);
if (cursor.getInt(cursor.getColumnIndex("favorite")) == 0) {
favoriteBox.setChecked(false);
} else {
favoriteBox.setChecked(true);
}
}
}
Class AllCityListFragment which extends Fragment
import java.io.IOException;
import java.util.ArrayList;
import android.os.Bundle;
import android.os.Handler;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemLongClickListener;
import android.widget.CheckBox;
import android.widget.ListView;
import android.widget.Toast;
public class AllCityListFragment extends Fragment {
private CustomList customAdapter;
private DatabaseHelper databaseHelper;
ArrayList<String> city_name = new ArrayList<String>();
ArrayList<String> country_name = new ArrayList<String>();
ArrayList<String> country_short = new ArrayList<String>();
ArrayList<CheckBox> check_box = new ArrayList<CheckBox>();
public static final String ARG_OS = "OS";
int pos;
String sql = "";
ListView list;
View view;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.all_city_layout, null);
databaseHelper = new DatabaseHelper(view.getContext());
try {
databaseHelper.createDataBase();
databaseHelper.openDataBase();
} catch (IOException e) {
// TODO Auto-generated catch block
Toast.makeText(view.getContext(), "Error: " + e.getMessage(),
Toast.LENGTH_LONG).show();
e.printStackTrace();
}
list = (ListView) view.findViewById(R.id.citylist);
list.setFocusable(false);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View myview,
int position, long id) {
Toast.makeText(getActivity(),
position + " " + city_name.get(position),
Toast.LENGTH_LONG).show();
}
});
sql = "SELECT _id, city_name, country_name, country_short, favorite FROM city order by country_name asc;";
new Handler().post(new Runnable() {
@Override
public void run() {
customAdapter = new CustomList(getActivity(), databaseHelper
.getResult(sql), city_name, country_name,
country_short, check_box);
list.setAdapter(customAdapter);
}
});
return view;
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
}
In this picture I clicked "Shirajganj" but the Toast shows me "230 Thakurgaon" position =230 is correct but city_name.get(230) should be "Shirajganj" . I think it is doing wrong when I am trying to add value to ArrayList in binView in CustomList. How can I solve this problem?
