I am looking for something like this:
several <ItemTemplate> in one ListView.
But it was in .ASP and above my level.
What I need
Class Vitals: vTime, BP, Heart Rate, Respirations per Minute, etc.
Class Medications: mTime, RxName, RxRoute, RxDose, RxDoseUnit, etc.
Class Procedures: pTime, Intubation, IV insertion, Defibrillation, etc.
Classes Vitals, Medications and Procedures to be based on user input that inject in to a ListView (sorted chronologically). A "Many-to-One" if I may.
I've went through hours of "CustomAdapter & ListView" tutorials, code samples, walkthroughs.
Here is my current code (trashed and scattered) to show that I am actively working towards a solution:

I'd appreciate any and everything;
I'm working on a NEMSIS . org project;
I may even be searching with the wrong search terms for what I need.
All help is appreciated
have you try the getViewTypeCount() method in adapter,
it can define different itemView for your different data types.
for your case you need to define three layout items .
search some demos,it may help you .

I have problem with displaying values using ListView.
I created adapter extends Base Adapter and Setter & Getter for listview, however it stores
all values in one line.
This is displayed screen
I would like to display like this
This is my adapter class
public class DataShow_List_Adapter extends BaseAdapter {
private LayoutInflater layoutInflater;
private ArrayList<TimeTable_ListItems> timeTable_listItems;
public DataShow_List_Adapter(Context context){
this.layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void SetTimeTable_listItems_adapter(ArrayList<TimeTable_ListItems> timeTable_listItems){
this.timeTable_listItems = timeTable_listItems;
}
#Override
public int getCount() {
return timeTable_listItems.size();
}
#Override
public Object getItem(int position) {
return timeTable_listItems.get(position);
}
#Override
public long getItemId(int position) {
return timeTable_listItems.get(position).getId();
}
#SuppressLint("ViewHolder")
#Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = layoutInflater.inflate(R.layout.timetable_datashow_listview_row,parent,false);
((TextView)convertView.findViewById(R.id.Title_List)).setText(timeTable_listItems.get(position).getTitle());
((TextView)convertView.findViewById(R.id.SubTitle_List)).setText(timeTable_listItems.get(position).getSubTitle());
((TextView)convertView.findViewById(R.id.Start_Time_List)).setText(timeTable_listItems.get(position).getStart_Time());
((TextView)convertView.findViewById(R.id.End_Time_List)).setText(timeTable_listItems.get(position).getEnd_time());
return convertView;
}
}
This is Setter & Getter
public class TimeTable_ListItems {
private long id;
private String title;
private String subTitle;
private String start_Time;
private String end_time;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getSubTitle() {
return subTitle;
}
public void setSubTitle(String subTitle) {
this.subTitle = subTitle;
}
public String getStart_Time() {
return start_Time;
}
public void setStart_Time(String start_Time) {
this.start_Time = start_Time;
}
public String getEnd_time() {
return end_time;
}
public void setEnd_time(String end_time) {
this.end_time = end_time;
}
}
This is method that returns String from Database
public String getTitle_database_mon(){
sqLiteDatabase = this.getReadableDatabase();
String[] columns = new String[]{COLUMN_TITLE, COLUMN_MON,};
#SuppressLint("Recycle")
Cursor cursor =
sqLiteDatabase.query(TABLE_TIMETABLE,columns,COLUMN_MON + "=" + 1 ,null,null,null,null);
int iTitle = cursor.getColumnIndex(COLUMN_TITLE);
StringBuilder result = new StringBuilder();
for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()){
result.append(cursor.getString(iTitle)).
append("\n\n");
}
return result.toString();
}
This is My fragment
public class Monday_DataShow_Fragment extends Fragment {
private View root;
private ListView listView_mon;
private ArrayList<TimeTable_ListItems> timeTable_listItems_array;
private TimeTable_ListItems timeTable_listItems;
private DatabaseTimetable databaseTimetable;
private DataShow_List_Adapter dataShow_list_adapter;
public Monday_DataShow_Fragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
root = inflater.inflate(R.layout.fragment_monday__data_show_, container, false);
findViews();
databaseTimetable = new DatabaseTimetable(getActivity());
timeTable_listItems = new TimeTable_ListItems();
dataShow_list_adapter = new DataShow_List_Adapter(requireActivity());
setListItems();
timeTable_listItems_array.add(timeTable_listItems);
dataShow_list_adapter.SetTimeTable_listItems_adapter(timeTable_listItems_array);
listView_mon.setAdapter(dataShow_list_adapter);
// Inflate the layout for this fragment
return root;
}
private void setListItems(){
timeTable_listItems_array = new ArrayList<>();
timeTable_listItems.setTitle(databaseTimetable.getTitle_database_mon());
dataShow_list_adapter.notifyDataSetChanged();
}
private void findViews(){
listView_mon = root.findViewById(R.id.listview_monday);
}
}
If you have any suggestions I'd like to hear it.
The issue is you have only one title as title String. getTitle_database_mon returns result.toString(). If you want to have multiple rows you need to have multiple objects in your list and unique titles for each. So instead of one TimeTable_ListItems. You need to be using ArrayList<TimeTable_ListItems> instead and have each entry contain a title so it is going to create multiple rows in the list instead of one.
In an app using FastAdapter and ConstraintLayout I display a list of completed games (pardon the non-english characters in the screenshot):
When the app user clicks an item in the list (anywhere in the item), I would like to display an image view with a square game board and also change the plus image view to minus:
For that I have already prepared a method:
private void toggleDetails() {
if (mBoard.getVisibility() == View.GONE) {
mBoard.setVisibility(View.VISIBLE);
mDetails.setImageResource(R.drawable.minus_circle_gray);
} else {
mBoard.setVisibility(View.GONE);
mDetails.setImageResource(R.drawable.plus_circle_gray);
}
}
However my problem is that I am not sure, where to call the method.
Should I add a click listener to the fast adapter object or should I add it to my view holder?
Also, when looking at ExpandableSampleActivity example, I notice that there is some animation and wonder how to animate my disclosure of the mBoard image view...

UPDATE:
I have tried adding a boolean details to my model and use it in the bindView method (true means display the mBoard), but the app behaves erratically now, wrong details are shown and that not immediately after clicking -
Here the new Fragment source code:

// THIS METHOD IS CALLED IN DEBUGGER, BUT VIEWS ARE NOT UPDATED

}
});
And here the changed FinishedGameItem model:

private final static String WON = "won";
private final static String LOST = "lost";
public boolean details; // TRIED TO ADD THIS BOOLEAN

The app kind of works, but erratically:
Judging by your code, it seems that you may have forgot to actually tell the adapter that your backing model (FinishedGameItem) has changed. Calling notifyItemChanged(position) might help.
mFastAdapter.withSelectable(true);
mFastAdapter.withOnClickListener(new OnClickListener<FinishedGameItem>() {
#Override
public boolean onClick(View v, #NonNull IAdapter<FinishedGameItem> adapter, #NonNull FinishedGameItem item, int position) {
item.details = !item.details;
mFastAdapter.notifyItemChanged(position);
return true;
}
});
Here I'm trying to make a quiz application without using databases (requirement). Each question has 4 options.
I had made a class for Questions. Now, in the activity in which I want to show my data, I'm unable to get method to fetch the data from the QuestionModelClass.
I had made 2D Array but it gets more complicated to get it. Is there any way to bind 3 of the classes (QuestionModelClass, Adapter class, and Activity class)?
public class QuestionsModelClass {
private String sQuestion;
private String sRightAnswer;
private List<String> sOptions;
QuestionsModelClass(){
sQuestion = null;
sRightAnswer = null;
sOptions = null;
}
public QuestionsModelClass(String sQuestion, String sRightAnswer, List<String> sOptions) {
this.sQuestion = sQuestion;
this.sRightAnswer = sRightAnswer;
this.sOptions = sOptions;
}
public String getsQuestion() {
return sQuestion;
}
public void setsQuestion(String sQuestion) {
this.sQuestion = sQuestion;
}
public String getsRightAnswer() {
return sRightAnswer;
}
public void setsRightAnswer(String sRightAnswer) {
this.sRightAnswer = sRightAnswer;
}
public List<String> getsOptions() {
return sOptions;
}
public void setsOptions(List<String> sOptions) {
this.sOptions = sOptions;
}
}
And my Adapter Class
public class QuizAdapter extends BaseAdapter {
private Context context;
private List<QuestionsModelClass> questionClassList;
private String[][] options;
private LayoutInflater inflater;
private QuizAdapter(Context c, List<QuestionsModelClass> l){
this.context= c;
this.questionClassList = l;
inflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
return questionClassList.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = inflater.inflate(R.layout.questionpattern, parent,false);
QuestionsModelClass questions = questionClassList.get(position);
TextView quesText= convertView.findViewById(R.id.questionTextView);
RadioButton radioButtonA = convertView.findViewById(R.id.optionA);
RadioButton radioButtonB = convertView.findViewById(R.id.optionB);
RadioButton radioButtonC = convertView.findViewById(R.id.optionC);
RadioButton radioButtonD = convertView.findViewById(R.id.optionD);
return convertView;
}
And this is the Activity class in which I am trying to implement all the functions
public class QuizActivity extends Activity {
final Context context= this;
private List<QuestionsModelClass> classObject;
Button okayButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_quiz);
String[] question= new String[]{"Q1. ABDE", "Q2. ADDASD"};
String[][] op;
String[] right = new String[]{"abc","def"};
classObject = new ArrayList<>();
op= new String[][]{
{"a1", "2", "3", "4"},
{"b1","b2","b3","b4"}};
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.customdialoguebox);
dialog.show();
okayButton = (Button) dialog.findViewById(R.id.okayButton);
okayButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(QuizActivity.this,"Good Luck!", Toast.LENGTH_SHORT).show();
dialog.cancel();
}
});
}
I am running into an issue where I use 2 separate adapters, and 2 seperate GridViews (1 Adapter, for 1 GridView), and am basically removing items from either adapter, and adding it to the other if the item is pressed, and vice versa.
When I press and item in one GridView, the item will be removed from its respective adapter and put into the other GridView and its respective adapter. The issue seems to be with the way the data is being stored (potentially) because when I add the item to the adapter, the icons are totally different from what they should be.
Note: I also noticed that this only happens for the items pressed after the first one is pressed. So the first items data will be added/removed properly. However, I have found that when the item that takes on the first position of the associated adapter, will now have the icon of the previously removed item.
What can I do so ensure that the data stays consistent with the item that is pressed?.

Can you show the place where you're populating the list of SettingViews? Is your data model (SettingView) extends View? It is not the best idea to use the view object as model..
I need to implement an endless pagination listview in my code, I've searched online and I saw a lot of examples, but none of them is using database, my app does the following:
it connects to an API and retrieves the data with json and show it in a listview, ok that works fine, but I want that listview to have an infinite scroll, like the facebook one.
I don't want anyone to write the code for me, I'm asking to someone guide me on wich is the better way to achieve that, I'll share some of my code, so you can understand:
try {
//Repositorio is my database
Repositorio mRepositorio = new Repositorio(getActivity());
List listaDeClientes = mRepositorio.getClientes();
System.out.println(listaDeClientes);
TextView total = (TextView) rootView.findViewById(R.id.totalClientes);
total.setText(getTotalClientes(mRepositorio.getTotalRegistros("clientes")));
final ArrayAdapter ad = new ClienteViewAdapter(this.getActivity(), R.layout.fragment_cliente_item, listaDeClientes);
ListView lv = (ListView) rootView.findViewById(R.id.listaClientes);
lv.setVerticalFadingEdgeEnabled(true);
lv.setVerticalScrollBarEnabled(true);
lv.setAdapter(ad);
} catch (Exception e) {
e.printStackTrace();
}
return rootView;
}
ClienteViewAdapter:
public class ClienteViewAdapter extends ArrayAdapter<ClienteModel> {
private final LayoutInflater inflater;
private final int resourceId;
public ClienteViewAdapter(Context context, int resource, List<ClienteModel> objects) {
super(context, resource, objects);
this.inflater = LayoutInflater.from(context);
this.resourceId = resource;
}
#Override
public View getView(int position, View view, ViewGroup parent) {
ClienteModel mClienteModel = getItem(position);
view = inflater.inflate(resourceId, parent, false);
TextView tvId = (TextView) view.findViewById(R.id.clienteId);
TextView tvNome = (TextView) view.findViewById(R.id.clienteNome);
TextView tvTipo = (TextView) view.findViewById(R.id.clienteTipo);
tvId.setText(String.valueOf(mClienteModel.getClientes_id()));
tvNome.setText(mClienteModel.getNome());
tvTipo.setText(mClienteModel.getTipo());
return view;
}
}
