I have an ArrayList to represent in a ListView by an Adapter:
private ArrayList <Contact> listContacts = new ArrayList <Contact> ();
This is the (simple) Contact Class:
public class Contact {
String pic;
String name;
String surname1;
String surname2;
String phonenumber;
}
And this is the Adapter Class:
public class ContactsAdapter extends ArrayAdapter<Contact> {
private static class ViewHolder {
ImageView pic;
TextView name;
TextView surname1;
TextView surname2;
TextView phonenumber;
}
Context context;
public ContactsAdapter(Context context, int textViewResourceId, ArrayList<Contact> items) {
super(context, textViewResourceId, items);
this.context = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = LayoutInflater.from(this.getContext())
.inflate(R.layout.layout_contact, parent, false);
holder = new ViewHolder();
holder.pic= (ImageView) convertView.findViewById(R.id.pic);
holder.name= (TextView) convertView.findViewById(name);
holder.surname1= (TextView) convertView.findViewById(R.id.surname1);
holder.surname2= (TextView) convertView.findViewById(R.id.surname2);
holder.phonenumber= (TextView) convertView.findViewById(R.id.phonenumber);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
Contact item = getItem(position);
if (item!= null) {
int idImage = context.getResources().getIdentifier(item.pic, "drawable", context.getPackageName());
holder.pic.setImageResource(idImage);
holder.name.setText(item.name);
holder.surname1.setText(item.surname1);
holder.surname2.setText(item.surname2);
holder.phonenumber.setText(item.phonenumber);
}
return convertView;
}
}
The MainActivity is like this:
public class MainActivity extends ListActivity {
private ArrayList <Contact> listContacts = new ArrayList <Contact> ();
ContactsAdapter contactsAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
boolean result = loadListFromFiles();
if (result) {
loadContacts();
}
}
private void loadContacts() {
contactsAdapter = new ContactsAdapter(getApplicationContext(), R.layout.activity_main, listContacts);
setListAdapter(contactsAdapter);
}
The loadListFromFiles code:
private boolean loadListFiles(){
boolean result = false;
Context context = getApplicationContext();
File path = context.getFilesDir();
File[] files = path.listFiles();
Log.d("Files", "Size: "+ files.length);
for (int i = 0; i < files.length; i++)
{
Log.d("Files", "FileName:" + files[i].getName());
result = loadFile(files[i].getName());
}
return resultado;
}
private boolean loadFile(String fileName) {
String[] arrayContact = new String[4];
try
{
BufferedReader fin =
new BufferedReader(
new InputStreamReader(
openFileInput(fileName)));
int i = 0;
String line= "";
while ((line= fin.readLine()) != null) {
arrayContact[i] = linea;
i++;
}
fin.close();
Contact contact = new Contact();
contact.pic = arrayContact[3];
contact.name= arrayContact[0];
contact.surname1 = arrayContact[1];
contact.surname2 = arrayContact[2];
contact.phonenumber= arrayContact[3];
listContacts.add(contact);
return true;
}
catch (Exception ex)
{
Log.e("Files", "Error to read file by memory");
return false;
}
}
The ArrayList is right, but the layout don't show anything.
Override getCount() and getItem() methods to return count and contact item.
#Override
public int getCount() {
if(items == null)
return 0;
return items.size();
}
#Override
public Contact getItem(int i) {
return items.get(i);
}
Also, create one variable items in Adapter class and assign it to parameter passed to adapter constructor.
ArrayList<Contact> items;
public ContactsAdapter(Context context, int textViewResourceId, ArrayList<Contact> items) {
super(context, textViewResourceId, items);
this.context = context;
this.items = items;
}

i am trying to display json data in listview but listview is empty logcat shows no error and app also don't get crashed i am unable to find the error here is the method that adds json data to the adapter
public void setTextToTextView(JSONArray jsonArray) {
contactAdapter = new ContactAdapter(this,R.layout.row_layout);
listView.setAdapter(contactAdapter);
try {
int count = 0;
String stop;
while(count < jsonArray.length())
{
JSONObject JO = jsonArray.getJSONObject(count);
stop = JO.getString("stop");
Contacts contacts = new Contacts(stop);
contactAdapter.add(contacts);
count++;
}
}
catch (JSONException e) {
e.printStackTrace();
}
}
here is the Adapter class
public class ContactAdapter extends ArrayAdapter{
List list = new ArrayList();
public ContactAdapter(Context context, int resources){
super(context,resources);
}
public void add(Contacts object)
{
super.add(object);
list.add(object);
}
#Override
public int getCount() {return list.size();}
#Override
public Object getItem(int position) {return list.get(position);}
#Override
public View getView(int position,View convertView,ViewGroup parent)
{
View row;
row = convertView;
ContactHolder contactHolder;
if(row == null)
{
LayoutInflater layoutInflater = (LayoutInflater)this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = layoutInflater.inflate(R.layout.row_layout,parent,false);
contactHolder = new ContactHolder();
contactHolder.tx_stop = (TextView)row.findViewById(R.id.tx_stop);
row.setTag(contactHolder);
}
else
{
contactHolder = (ContactHolder)row.getTag();
}
Contacts contacts = (Contacts)this.getItem(position);
contactHolder.tx_stop.setText(contacts.getStop());
return row;
}
static class ContactHolder
{
TextView tx_stop;
}
}
Call
contactAdapter.notifyDataSetChanged();
after your while loop.
You can create ArrayList<Contacts> contactsArray = new ArrayList<Contacts>(); then push all objects in it after that to set your adapter with passed array. Your method should look like:
public void setTextToTextView(JSONArray jsonArray) {
ArrayList<Contacts> contactsArray = new ArrayList<Contacts>();
try {
int count = 0;
String stop;
while(count < jsonArray.length()) {
JSONObject JO = jsonArray.getJSONObject(count);
stop = JO.getString("stop");
Contacts contacts = new Contacts(stop);
contactsArray.add(contacts);
count++;
}
contactAdapter = new ContactAdapter(this,R.layout.row_layout, contactsArray);
listView.setAdapter(contactAdapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
In your adapter do the following:
ArrayList<Contacts> list = new ArrayList<Contacts>();
public ContactAdapter(Context context, int resources, ArrayList<Contacts> list){
super(context,resources);
this.list = list;
}
That's all. Hope to help!

Get the value in a string and call it whereever you want orelse if you want to store it somewhere use sharedpreference.
Store values with sharedpreference :
SharedPreference mypref = getActivity().getSharedPreferences("name_key", Context.MODE_PRIVATE);
SharedPreferences.Editor editor= mypref.edit();
editor.putString("name_key",name_string);
editor.apply();
To retrieve it from anywhere in your program:
SharedPreference mypref = getActivity().getSharedPreferences("name_key", Context.MODE_PRIVATE);
String av = mypref.getString("name","");

i can show book name and book detail in listview finely but image is not showing ..
i am getting value for book_image is http:\/\/X.X.X.X\/admin\/book_images\/232513pic9.png how to show in listview from that path..
I think you will need to implement your own adapter and use some library to display the image from URL.
My recommendation is Picasso
This is an example to implement your own adapter
BookListAdapter.java
public class BookListAdapter extends ArrayAdapter<BookModel> {
private ArrayList<BookModel> bookModels;
private Context context;
public BookListAdapter(Context context, int resource, ArrayList<BookModel> bookModels) {
super(context, resource, bookModels);
this.bookModels = bookModels;
this.context = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
ViewHolder viewHolder;
if (rowView == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView = inflater.inflate(R.layout.book_child_list, parent, false);
ViewHolder viewHolder = new ViewHolder();
viewHolder.bookIcon = (ImageView) rowView
.findViewById(R.id.bookIcon);
viewHolder.bookName = (TextView) rowView
.findViewById(R.id.bookName);
viewHolder.bookDetail = (TextView) rowView
.findViewById(R.id.bookDetail);
rowView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) rowView.getTag();
}
final BookModel bookModel = bookModels.get(position);
Picasso.with(context).load(bookModel.getBookImageUrl()).into(viewHolder.bookIcon);
viewHolder.bookName.setText(bookModel.getBookName());
viewHolder.bookDetail.setText(bookModel.getBookDetail());
return rowView;
}
#Override
public int getCount() {
return bookModels.size();
}
static class ViewHolder {
public ImageView bookIcon;
public TextView bookName;
public TextView bookDetail;
}
}
BookModel.java
public class BookModel {
private String bookName;
private String bookDetail;
private String bookImageUrl;
public BookModel() {
bookName = "";
bookDetail = "";
bookImageUrl = "";
}
public String getBookName() {
return bookName;
}
public void setBookName(String bookName) {
this.bookName = bookName;
}
public String getBookDetail() {
return bookDetail;
}
public void setBookDetail(String bookDetail) {
this.bookDetail = bookDetail;
}
public String getBookImageUrl() {
return bookImageUrl;
}
public void setBookImageUrl(String bookImageUrl) {
this.icons = bookImageUrl;
}
}
Where BookModel class is a class where you can wrap your data (book name, book detail, book image) and pass it as a list to the adapter.
for example :
protected Boolean doInBackground(final String... args) {
url = url + "?custom_iid=" + cus_id;
Log.d("Passing Url", url);
CustomListAdapter jParser = new CustomListAdapter();
JSONArray json = jParser.getJSONFromUrl(url);
ArrayList<BookModel> bookModelList = new ArrayList<BookModel>();
if (json != null) {
for (int i = 0; i < json.length(); i++) {
try {
BookModel bookModel = new BookModel();
JSONObject c = json.getJSONObject(i);
String b_image = c.getString("b_image");
String b_name = c.getString("b_name");
String b_detail = c.getString("b_publisher");
Log.d("detail", "" + b_image);
bookModel.setBookName(b_name);
bookModel.setBookDetail(b_detail);
bookModel.setBookImageUrl(b_image);
bookModelList.add(bookModel);
} catch (JSONException e) {
e.printStackTrace();
}
}
}
if(bookModelList.size()>0) {
BookListAdapter bookListAdapter = new BookListAdapter(MainActivity.this, R.id.yourlistview, bookModelList );
}
return null;
}
I hope my answer can help you!
lv.setAdapter(adapter);
use AQuery lib.
and just write this code in your custom adapter:
AQuery aQuery = new AQuery(context);
aQuery.id(your image id).image(your url,true,true);

Get rid of these fields in your adapter
private ArrayList<Country> originalList;
private ArrayList<Country> countryList;
You are modifying the countryList that is being passed to the super call in your adapter but you are reading from the countryList that is stored as a field inside of your adapter which never gets modified when you add a new country!
You are creating a copy of your original countrylist.. but you never modify the copy after creating it

Now in MainActiivty i am trying to set the adapter so that it populates the list from the Array
public class MainActivity extends SherlockFragmentActivity implements

"Wayanad", "Bandipur National Park", "Chickmaglur",
"Bandipura", "Coorg", "Kodaikanal", "Hampi",

"Talakadu", "Savana Durga" };
public SearchView mSearchView;
private TextView mStatusView;
private Menu mainMenu = null;
PlacesListAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i("Nomad", "onCreate");
ListView listView = (ListView) findViewById(R.id.place_list);
adapter = new PlacesListAdapter(this, resource, places);
}
}
I am not sure what to set for resources in adapter = new PlacesListAdapter(this, resource, places);
Initialize the resource variable:
// it doesn't matter what values you assing to the resource variable because you build
// the row layout yourself in the getView method of the adapter
int resource = android.R.layout.simple_list_item_1;
adapter = new PlacesListAdapter(this, resource, places);
Edit:
List<Place> thePlaces = new ArrayList<Place>();
for (int i = 0; i < places.length; i++) {
Place pl = new Place("NO_ID", places[i], "NO_DISTANCE", "NO_CATEGORYICON");
thePlaces.add(pl);
}
int resource = android.R.layout.simple_list_item_1;
adapter = new PlacesListAdapter(this, resource, thePlaces);
pass row layout id instead of default android layout if your are creating custom adapter by extending ArrayAdapter:
adapter = new PlacesListAdapter(this,R.layout.item_place, places);
instead of
adapter = new PlacesListAdapter(this, resource, places);
