Hellow there i've made a custom adapted for my listview but i dont know the reason why its displaying it in this way:
Display
This is how i generate the list that i use on listview:
final ArrayList<String> list = db_query.get_marks();
final ArrayList<String> list_trim = db_query.get_trim();
final ArrayList<String> list_merged = new ArrayList<String>();
for (int i=0; list.size()>i; i++){
list_merged.add(list.get(i));
list_merged.add(list_trim.get(i));
}
String[] list_final = new String[list_merged.size()];
this.size = list.size();
list_merged.toArray(list_final);
ListAdapter adapter = new Custom_Adapter(this, list_final);
So what i should be displaying is : AB AB but its actually displaying AA BB
7 values in the image are A
1 values in the image are B
The custom view code:
LayoutInflater inflater = LayoutInflater.from(getContext());
View customView = inflater.inflate(R.layout.custom_row, parent, false);
TextView text1 = (TextView) customView.findViewById(R.id.textView4);
TextView text2 = (TextView) customView.findViewById(R.id.textView5);
text1.setText((String) getItem(position));
text2.setText((String) getItem(position));
return customView;
Hope you can help me
public Custom_Adapter(Context context, ArrayList<Model> list) {
super(context, R.layout.custom_row, list);
}
You're setting the same value twice
text1.setText((String) getItem(position));
text2.setText((String) getItem(position));
Make a model file Model.java:
public class Model {
public String a;
public String b;
}
Replace this code:
final ArrayList<String> list = db_query.get_marks();
final ArrayList<String> list_trim = db_query.get_trim();
final ArrayList<Model> list_merged = new ArrayList<Model>();
for (int i = 0; i < list.size(); i++){
Model model = new Model();
model.a = list.get(i);
model.b = list_trim.get(i);
list_merged.add(model);
}
ListAdapter adapter = new Custom_Adapter(this, list_final);
And finally this:
text1.setText((String) ((Model)getItem(position)).a);
text2.setText((String) ((Model)getItem(position)).b);
Change you adapter to accept the Model object.

I have a json array which has bullet1 and bullet 2 values to be binded in a single spinner.
[{"id":7,"description":"Height dusting","is_active":true,"createdBy":1,"CreatedOn":"2018-02-20T19:48:16","ModifiedBy":null,"ModifiedOn":null,"Bullet1":"Done","Bullet2":"Not Done"},
{"id":8,"description":"Cobwebs removed","is_active":true,"createdBy":1,"CreatedOn":"2018-02-20T19:48:17","ModifiedBy":null,"ModifiedOn":null,"Bullet1":"Yes","Bullet2":"No"},
{"id":9,"description":"Side walls cleaned","is_active":true,"createdBy":1,"CreatedOn":"2018-02-20T19:48:17","ModifiedBy":null,"ModifiedOn":null,"Bullet1":"Yes","Bullet2":"No"}],"token":null,"ActionName":"GetQuestionnairesByLocation"}]
So now dynamically there are 3 spinners and according to that only 2 values should be seen in respective spinners.
First Spinner - Done, Not Done.
Second Spinner - Yes, No.
Third Spinner - Yes, No.
But the problem i am facing is every spinner is getting binded with 6 values.(Done, Not Done, Yes, No, Yes, No)
Code :
ArrayList<UserFormModel> arrayList = new ArrayList<>();
List<String> list = new ArrayList<>();
JSONArray jsonArray = jsonObject.getJSONArray("ResponseArray");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject1 =
jsonArray.getJSONObject(i);
UserFormModel userFormModel = new
UserFormModel();
userFormModel.setId(jsonObject1.getInt("id"));
userFormModel.setDescription
(jsonObject1.getString("description"));
list.add(jsonObject1.getString("Bullet1"));
list.add(jsonObject1.getString("Bullet2"));
userFormModel.setBulletsList(list);
arrayList.add(userFormModel);
}
UserFormsAdapter locationMasterAdapter = new
UserFormsAdapter(GetQuestions.this, arrayList);
listView.setAdapter(locationMasterAdapter);
locationMasterAdapter.notifyDataSetChanged();
Adapter class :
private ArrayList<UserFormModel> userFormModelArrayList;
Activity home;
public UserFormsAdapter(Activity home, ArrayList<UserFormModel>
userFormModelArrayList) {
this.home = home;
this.userFormModelArrayList = userFormModelArrayList;
}
#Override
public View getView(final int position, View convertView, ViewGroup
parent) {
View grid;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater)
home.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
grid = inflater.inflate(R.layout.get_questions_row, null);
} else {
grid = (View) convertView;
}
final UserFormModel userFormModel =
userFormModelArrayList.get(position);
TextView textDesc = (TextView) grid.findViewById(R.id.textDesc);
Spinner spinner = (Spinner) grid.findViewById(R.id.chooseBullets);
String desc = userFormModel.getDescription();
textDesc.setText(desc);
CustomDropdownAdapter customDropdownAdapter = new
CustomDropdownAdapter(home, userFormModel.getBulletsList());
spinner.setAdapter(customDropdownAdapter);
return grid;
}
what is it that i need to do for my above solution to run??
this is beacuase you are initialize your List outside of for loop. try to initialize your list in for loop.
ArrayList<UserFormModel> arrayList = new ArrayList<>();
List<String> list;\\don't initialize the list here just declare the list.
JSONArray jsonArray = jsonObject.getJSONArray("ResponseArray");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject1 =
jsonArray.getJSONObject(i);
list = new ArrayList<>();\\try to initialize your list here.
UserFormModel userFormModel = new
UserFormModel();
userFormModel.setId(jsonObject1.getInt("id"));
userFormModel.setDescription
(jsonObject1.getString("description"));
list.add(jsonObject1.getString("Bullet1"));
list.add(jsonObject1.getString("Bullet2"));
userFormModel.setBulletsList(list);
arrayList.add(userFormModel);
}
UserFormsAdapter locationMasterAdapter = new
UserFormsAdapter(GetQuestions.this, arrayList);
listView.setAdapter(locationMasterAdapter);
locationMasterAdapter.notifyDataSetChanged();
I have a custom ListView with Spinner that fill with a ListArray.
It works fine without ListView Scroll
But when I add some items to my custom ListView and I select one item of first or second on my Spinner and I scroll down my ListView (until that row disappear) I see another Spinner on bottom items will selected (like the upper)
My selection kept but another Spinner on bottom ListView be select

Can anybody help me?
First of all just tell me why are you using that much arraylists, can't you just use a single one with custom data type. In that single array all your values will be associated to each other and it will easy to manage them.
The solution for your issue that I can suggest is to create a single ArrayList with custom data type including all your values of all arraylists given above. And don not initialize your Array in Adapter. Initialize and add values where you are setting Adapter (In your Activity). you have to add a parameter in your main array let's say "selectedValue", by default it will be "all" but when user will select some value you will update the value of item on that specific position.
And then in your getView method you will check the value of "selectedValue" for each item, if it is equals to "all" then you will set it otherwise you will set the value of "selectedValue" to your spinner. Just keep one thing in mind you have to set a value to spinner of each item in both if and else clause.
I would like to use Picasso library to download and show images that are in URL's inside JSON data from my server.
I've lost all hope, I saw something about custom adapter but to no avail.
I need help here.
Here's how I do stuff now to show data from json inside onPostExecute:
protected void onPostExecute(JSONObject objdanejson){
pDialog.dismiss();
try {
android = objdanejson.getJSONArray(TAG_ZAWARTOSC);
for(int i = 0; i < android.length(); i++){
JSONObject c = android.getJSONObject(i);
final String akt_tytul = c.getString(TAG_TYTUL);
final String akt_skrot = c.getString(TAG_SKROT);
final String akt_tresc = c.getString(TAG_TRESC);
final String akt_id = c.getString(TAG_ID);
final String akt_IMG = c.getString(TAG_IMG);
HashMap<String, String> map = new HashMap<String, String>();
map.put(TAG_TYTUL, akt_tytul);
map.put(TAG_SKROT, akt_skrot);
map.put(TAG_ID, akt_id);
map.put(TAG_TRESC, akt_tresc);
map.put("http://www.apirest.poligon.webimpuls.pl/"+TAG_IMG, akt_IMG);
oslist.add(map);
lista_aktualnosci = (ListView)findViewById(R.id.lista_aktualnosci);
final ListAdapter adapter = new SimpleAdapter(aktualnosci.this, oslist,
R.layout.aktualnosc_item,
new String[]{TAG_TYTUL, TAG_SKROT, TAG_IMG}, new int[]{R.id.aktTytul, R.id.aktSkrot, R.id.aktIMG});
lista_aktualnosci.setAdapter(adapter);
lista_aktualnosci.setOnItemClickListener(new AdapterView.OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(aktualnosci.this, "Kliknąłeś na " + oslist.get(+position).get("akt_tytul"),Toast.LENGTH_SHORT).show();
Intent czytaj = new Intent(aktualnosci.this, aktualnosc_czytaj.class);
czytaj.putExtra("tytuł",oslist.get(+position).get("akt_tytul"));
czytaj.putExtra("tresc",oslist.get(+position).get("akt_tresc"));
czytaj.putExtra("id",oslist.get(+position).get("akt_id"));
startActivity(czytaj);
}
});
}
}
catch (JSONException e) {
e.printStackTrace();
}
}
EDIT:
How my custom controler looks:
oslist.add(map);
lista_aktualnosci = (ListView)findViewById(R.id.lista_aktualnosci);
/* final ListAdapter adapter = new SimpleAdapter(aktualnosci.this, oslist,
R.layout.aktualnosc_item,
new String[]{TAG_TYTUL, TAG_SKROT}, new int[]{R.id.aktTytul, R.id.aktSkrot});
*/
class ListAdapter extends ArrayAdapter<ClipData.Item> {
public ListAdapter(Context context, int textViewResourceId) {
super(context, textViewResourceId);
}
public ListAdapter(Context context, int resource, List<ClipData.Item> items) {
super(context, resource, items);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(getContext());
v = vi.inflate(R.layout.aktualnosc_item, null);
}
ClipData.Item p = getItem(position);
if (p != null) {
aktTytul = (TextView)findViewById(R.id.aktTytul);
aktSkrot = (TextView)findViewById(R.id.aktSkrot);
aktIMG = (ImageView)findViewById(R.id.aktIMG);
}
return v;
}
}
lista_aktualnosci.setAdapter(adapter);
Create a class that extends Simple Adapter or Base Adapter. In getView() the adapter will ask you to create a list item when this is needed. As you create the item you can use Picasso to display the image in whatever image view you've selected for this purpose.
That being said you should ditch ListView and use RecyclerView instead - for which you can find all the information you need here
Other stuff that may improve your code are things like Retrofit and Gson.
Does that help?
you can get your image from listview. You can this code your activity after set adapter then you can set your imageview.
for(int i = 0; i < this.listView.getChildCount(); i ++) {
View view = this.listView.getChildAt(i);
ImageView img= (ImageView)view.findViewById(R.id.yourimage);
//do something your image
}
I just want to ask something about showing data to checkbox, right now, I just have successful to showing data into checbox but, now I get trouble, when I have 1 data in my database, the checkbox show 2 data? here's my example database
Table Jurusan
id | nama
1 ipa
then I have function to read this database
public ArrayList<Jurusan> getAllLabel_jurusan()
{
ArrayList <Jurusan> point = new ArrayList<Jurusan>();
String selectQuery = "SELECT id, nama_jurusan from jurusan";
Cursor c = database.rawQuery(selectQuery, null);
if( c.moveToFirst() );
do
{
Jurusan j = new Jurusan();
j.setId(c.getLong(0));
j.setNama_jurusan(c.getString(1));
// adding to todo list
point.add(j);
}
while(c.moveToNext());
return point;
}
and this is my MainActivity
public class MainActivity extends Activity implements OnItemSelectedListener
{
Button myButton;
String tmp_nama;
long id_tampung;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myButton = (Button) findViewById(R.id.findSelected);
displayListView();
checkButtonClick();
}
private void displayListView()
{

}
My question is, the checkbox should showing 1 data from database, but when i run this code, the checkbox is showing 2 data with same value, can anybody help me?
example:
checbox1 (value:ipa)
checkbox2 (value:ipa)
i hope it should be like this...
checkbox1 (value:ipa)
In your displayListView(), you're duplicating the first entry in the stateList:
ArrayList<Jurusan> stateList = dataSource.getAllLabel_jurusan();
if(stateList.size()>0)
{
//GETTING THE DATA FROM DATABASE
id_tampung = stateList.get(0).getId();
tmp_nama = stateList.get(0).getNama_jurusan().toString();
//THE SET INTO CONSTRUCTOR
Jurusan _states = new Jurusan(id_tampung, tmp_nama);
//ADD TO ARRAY
stateList.add(_states);
}
I don't know what your intention here is but you probably could just remove this if block altogether.
The problem is in your code, you are add double values in your code. i added my comment before line of code.
//statelist contains an arraylist with your required data.
ArrayList<Jurusan> stateList = dataSource.getAllLabel_jurusan();
//you are checking here for zero.
if(stateList.size()>0)
{
//GETTING THE DATA FROM DATABASE
//here you are get id;
id_tampung = stateList.get(0).getId();
//here you are get name;
tmp_nama = stateList.get(0).getNama_jurusan().toString();
//THE SET INTO CONSTRUCTOR
//making an object of jurusan
Jurusan _states = new Jurusan(id_tampung, tmp_nama);
//ADD TO ARRAY
// and adding again the same arraylist. so that cause duplication.
//stateList already contained the data , which are you add this line.
stateList.add(_states);
}
yes , please replace the function displayListView as below.
private void displayListView()
{
ArrayList<Jurusan> stateList = dataSource.getAllLabel_jurusan();
/*
//GETTING THE DATA FROM DATABASE
id_tampung = stateList.get(0).getId();
tmp_nama = stateList.get(0).getNama_jurusan().toString();
//THE SET INTO CONSTRUCTOR
Jurusan _states = new Jurusan(id_tampung, tmp_nama);
//ADD TO ARRAY
stateList.add(_states);*/
// create an ArrayAdaptar from the String Array
//SETTING INTO CustomAdapter
dataAdapter = new MyCustomAdapter(this, R.layout.state_info,stateList);
ListView listView = (ListView) findViewById(R.id.listView1);
// Assign adapter to ListView
listView.setAdapter(dataAdapter);

I have an ArrayAdapter that I use to fill a listview, but I'm unable to create it outside the oncreate event, but at that time I don't have the data.
public class CusPickup extends Activity {
private OrdersReady orderready_data[];
private ListView lView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.orders);
Here I will get a null point exception.
OrderReadyAdapter adapter = new OrderReadyAdapter(this,R.layout.listview_item_row, orderready_data);
lView = (ListView)findViewById(R.id.listView1);
View header = (View)getLayoutInflater().inflate(R.layout.listview_header_row, null);
lView.addHeaderView(header);
lView.setAdapter(adapter);
getData();
}
}
Here I get the data from HTTP get.
private final Handler handler = new Handler() {
#Override
public void handleMessage(final Message msg) {
progressDialog.dismiss();
String bundleResult = msg.getData().getString("RESPONSE");
int TotalRecords = myResult.d.results.size();
for (int i = x; i < TotalRecords; i++ ) {
orderready_data[i] = new OrdersReady(myResult.d.results.get(i).myStr, myDate ,invResult.d.results.get(i).numberStr, invResult.d.results.get(i).qtyInt, myAmount)
}
}
}
If I place the OrderReadyAdapter her I get a code error with a fix "change OrderReadyAdapter(Context, Int, OrdersReady[]) to OrderReadyAdapter(Handle, Int, OrdersReady[]) if I change it I will get more errors.
Also I'm not sure if my declaration of the private OrdersReady orderready_data[] is correct, because if I declare it in code I would declare it like this: OrdersReady orderready_data[] = new OrdersReady[TotalRecords];
Thanks for any help.
New Adapter
public class OrderReadyAdapter extends ArrayAdapter<OrdersReady>{
Context context;
int layoutResourceId;
ArrayList<OrdersReady> data = null;
public OrderReadyAdapter(Context context, int layoutResourceId, ArrayList<OrdersReady> orderReadyArray) {
super(context, layoutResourceId, orderReadyArray);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.data = orderReadyArray;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
OrderHolder holder = null;
if(row == null)
{
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
holder = new OrderHolder();
holder.mytxt1 = (TextView)row.findViewById(R.id.mytxt1);
holder.mytxt2 = (TextView)row.findViewById(R.id.mytxt2);
holder.mytxt3 = (TextView)row.findViewById(R.id.mytxt3);
holder.mytxt4 = (TextView)row.findViewById(R.id.mytxt4);
holder.mytxt5 = (TextView)row.findViewById(R.id.mytxt5);
row.setTag(holder);
}
else
{
holder = (OrderHolder)row.getTag();
}
OrdersReady orderready = data.get(position);
holder.mytxt1.setText(orderready.place);
holder.mytxt2.setText(orderready.Date);
holder.mytxt3.setText(orderready.invoice);
holder.mytxt4.setText(String.valueOf(orderready.Qty));
holder.mytxt5.setText(String.valueOf(orderready.Amount));
return row;
}
static class OrderHolder
{
TextView mytxt1;
TextView mytxt2;
TextView mytxt3;
TextView mytxt4;
TextView mytxt5;
}
}
I suggest you change the OrdersReady[] into ArrayList. Initialize it in your onCreate method. Also make the orderReady adapter into a class field.
orderReadyArray = new ArrayList<OrderReady>();
ordersReadyAdapter = new OrderReadyAdapter(this,R.layout.listview_item_row, orderReadyArray);
lView = (ListView)findViewById(R.id.listView1);
View header = (View)getLayoutInflater().inflate(R.layout.listview_header_row, null);
lView.addHeaderView(header);
lView.setAdapter(ordersReadyAdapter);
This should initialize an empty listview as you don't have the data yet.
When you receive OrdersReady data from the server, update orderReadyArray as such:
orderReadyArray.clear(); // remove old data
for (int i = x; i < TotalRecords; i++ ) {
orderReadyArray.add(data); // add new data one by one
}
ordersReadyAdapter.notifyDataSetChanged(); // this forces the listview to repaint
Alternatively:
You can create a new adapter and assign it to the listview once you receive the data:
List<OrderReady> orderReadyArray = new ArrayList<OrderReady>(); // create a new array to hold data
for (int i = x; i < TotalRecords; i++ ) {
orderReadyArray.add(data); // add new data one by one
}
OrderReadyAdapter ordersReadyAdapter = new OrderReadyAdapter(this,R.layout.listview_item_row, orderReadyArray);
lView.setAdapter(ordersReadyAdapter);
This should update your list. If you still do not see the items, the problem is in the adapter, perhaps you are inflating the row incorrectly in getView() method.
