I have a ListView which extends BaseAdapter. I have a array list. The ListView inflates and populates correctly. I am using the flipper view to change the layout to another but the problem is when i clicked on the first item it rotate but the item at third or sixth row will also rotate
list view how can i fix it i only want the image is change of selected item
ArrayList<product_data> al=new ArrayList<product_data>();
class product_data
{
String post_title;
String newprice;
String oldprice;
String image;
String id;
product_data(String post_title,String newprice,String oldprice,String image,String id)
{
this.post_title=post_title;
this.newprice=newprice;
this.oldprice=oldprice;
this.image=image;
this.id=id;
}
}
to add data in arraylist
try {
JSONObject parentObject = new JSONObject(json.toString());
JSONObject userDetails = parentObject.getJSONObject("response");
JSONArray jarray=userDetails.getJSONArray("products_data");
for(int i=0;i<jarray.length();i++)
{
System.out.println("From the Dataaaa");
JSONObject c = jarray.getJSONObject(i);
String details=c.getString("details");
String image=c.getString("image");
String catagory=c.getString("catagory");
String new_price=c.getString("new_price");
String title=c.getString("title");
String id1=c.getString("id");
System.out.println("from ther first image"+image);

when i click on the first item it rotate and another view is coming
but when i scrolled the fourth item in below image will also rotate
i am using the on click listner on the relative views as in the code
Use ViewHolder for fill adapter. that may solve your issue
Example Code
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater mInflater = LayoutInflater.from(context);
final ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(
R.layout.news_by_categories_content, null);
holder = new ViewHolder();
holder.strNewsTitle = (TextView) convertView
.findViewById(R.id.txtNewsByCategories);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
NewsListByCategoriesItem obj = new NewsListByCategoriesItem(); // My Model class getting value from this
obj = newsArray.get(position);
holder.strNewsTitle.setText(obj.getStrNewsTitle());
return convertView;
}
class ViewHolder {
TextView strNewsTitle;
}
}

holder.placementCustomLinear is the custom leaner-layout need to be make it invisible
After some research i have solved my problem by adding a parent layout in the the xml and adding the some logic in the adapter class like
if (Util.ROLE.equalsIgnoreCase("admin")) {
holder.placementCustomLinear.setVisibility(View.VISIBLE);
}else
if(isPublic==0){
Log.i("inside if ", ""+isPublic);
Log.i("custom disply", custom);
int[] arry= stringToInteger(custom);
Log.i("numbers to ccheck ", ""+(arry));
for (int i = 0; i < arry.length; i++) {
if(custom.contains(Util.USER_ID)){
Log.i("true checked ", "inside");
holder.placementCustomLinear.setVisibility(View.VISIBLE);
notifyDataSetChanged();
}else{
holder.placementCustomLinear.setVisibility(View.GONE);
notifyDataSetChanged();
}
}
if(isPublic==0&&Util.USER_ID.contains(custom)){
holder.placementCustomLinear.setVisibility(View.VISIBLE);
notifyDataSetChanged();
}
}
else{
Log.i("else block ",""+isPublic);
if(isPublic==1)
holder.placementCustomLinear.setVisibility(View.VISIBLE);
notifyDataSetChanged();
}
my problem is solved thanks for the people who have give some suggestion

Becuase currently adding new data in Expenses ArrayList.
To update new item in ListView Adapter, need to add item in data-sorcude which is used inside adapter for getting data and getCount` method.
To achive same create a method in ExpensesListAdapter :
public void addAllItem(List<Expenses> strItem){
this.Expenses.addAll(strItem);
this.notifyDataSetChanged();
}
Now call addNewItem method to add new item when AlertDialog positive button click :
adapter.addNewItem(expenses.getAllExpenses());
Its been a week since I'm stuck with this problem.
I developed an application with a listView and editText to make a search. When I make a search the new list is showed very well but when I click on the item it redirect me to the item of the inicial list.
I don't know what to do please help me. These are my codes.
-For the ReaderListAdapter :
public class ReaderListAdapter extends BaseAdapter {
ArrayList<Reader> listReader = new ArrayList<Reader>();
ArrayList<Reader> arrayList;
LayoutInflater layoutInflater;
Context context;
int lastPosition = -1;
// constructeur
public ReaderListAdapter(Context context, ArrayList<Reader> listReader) {
this.listReader = listReader;
this.context = context;
arrayList = new ArrayList<Reader> ();;
layoutInflater = LayoutInflater.from(this.context);
arrayList.addAll(listReader);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return listReader.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return listReader.get(position);
}
#Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return arg0;
}
static class ViewHolder {
TextView nomView;
TextView priceView;
ImageView pictureView;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.reader_row, null);
holder = new ViewHolder();
// initialisation des vues
holder.nomView = (TextView) convertView.findViewById(R.id.name);
holder.priceView = (TextView) convertView.findViewById(R.id.price);
holder.pictureView = (ImageView) convertView.findViewById(R.id.picture);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
// affchier les données convenablement dans leurs positions
holder.nomView.setText(listReader.get(position).getName());
holder.priceView.setText(String.valueOf(listReader.get(position).getPrice()));
holder.pictureView.setBackgroundDrawable(listReader.get(position).getPicture());
// changer R.anim.ton_effet
Animation animation = AnimationUtils.loadAnimation(context,(position > lastPosition)
? R.anim.up_from_bottom: R.anim.up_from_bottom);
convertView.startAnimation(animation);
position=lastPosition;
return convertView;
}
// Filter Class
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
listReader.clear();
if(charText.length()==0){
listReader.addAll(arrayList);
}
else{
for (Reader c : arrayList) {
if (c.getName().toLowerCase(Locale.getDefault())
.contains(charText)) {
listReader.add(c);
}
}
}
notifyDataSetChanged();
}
}
-For the MainActivity:
public class MainActivity extends Activity {
String[] listNames = { "kooora","yahoo", "hespress"};
int[] listPrices = { 1, 2, 3 };
ArrayList<Reader> listReader = new ArrayList<Reader>();;
ArrayList<Reader> listReaderNew;
ListView lv;
EditText search;
ReaderListAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv = (ListView) findViewById(R.id.listReader);
search = (EditText) findViewById(R.id.search);
Drawable[] listPictures = {getResources().getDrawable(R.drawable.a1),getResources().getDrawable(R.drawable.a2),getResources().getDrawable(R.drawable.a3)};
for (int i = 0; i < listPictures.length; i++) {
listReader.add(new Reader(i + 1, listNames[i], listPictures[i], listPrices[i]));
}
adapter=new ReaderListAdapter(getApplicationContext(), listReader);
lv.setAdapter(adapter);
//lv.setAdapter(new ReaderListAdapter(getApplicationContext(), listReader));
search.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub
}
#Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub
}
#Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
String text = search.getText().toString().toLowerCase(Locale.getDefault());
MainActivity.this.adapter.filter(text);
}});
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
Intent intent=new Intent(MainActivity.this,WebActivity.class);
switch (position) {
case 0:
intent.setData(Uri.parse("http://www.kooora.com")) ;break;
case 1:
intent.setData(Uri.parse("http://www.yahoo.com")) ;break;
case 2:
intent.setData(Uri.parse("http://www.hespress.com")) ;break; }if (intent != null) {
startActivity(intent);
}}});}}
Please help me. Thanks in advance!
I think the code in onItemClick is causing this.
The problem:
searchTerm = "yahoo"
You filter yahoo and show the listitem for yahoo. Lets says its position in the list is 0. When the user clicks it, the onItemClick will be called and case 0: will be executed.
The correct logic should be,
Reader reader = parent.getAdapter().getItem(position);
String searchTerm = reader.getName(); // or whichever is the id for that listitem
if(searchTerm.contains("yahoo")) {
intent.setData(Uri.parse("http://www.yahoo.com"))
} // and so on
I have a ListView which extends BaseAdapter. I have a array list. The ListView inflates and populates correctly. I am using the flipper view to change the layout to another but the problem is when i clicked on the first item it rotate but the item at third or sixth row will also rotate
list view how can i fix it i only want the image is change of selected item
ArrayList<product_data> al=new ArrayList<product_data>();
class product_data
{
String post_title;
String newprice;
String oldprice;
String image;
String id;
product_data(String post_title,String newprice,String oldprice,String image,String id)
{
this.post_title=post_title;
this.newprice=newprice;
this.oldprice=oldprice;
this.image=image;
this.id=id;
}
}
to add data in arraylist
try {
JSONObject parentObject = new JSONObject(json.toString());
JSONObject userDetails = parentObject.getJSONObject("response");
JSONArray jarray=userDetails.getJSONArray("products_data");
for(int i=0;i<jarray.length();i++)
{
System.out.println("From the Dataaaa");
JSONObject c = jarray.getJSONObject(i);
String details=c.getString("details");
String image=c.getString("image");
String catagory=c.getString("catagory");
String new_price=c.getString("new_price");
String title=c.getString("title");
String id1=c.getString("id");
System.out.println("from ther first image"+image);
System.out.println("from the sdafdfadf"+details);
al.add(new product_data(title, new_price, new_price, image, id1));

}
when i click on the first item it rotate and another view is coming
but when i scrolled the fourth item in below image will also rotate
i am using the on click listner on the relative views as in the code
I have one idea on click of image first try to get Position and when you get Position then set new image background at that position.
