Please I need your help .I'am trying to take the date from an activity and then put it in an array list then print it in an ListView .
The problem is the data that I should take it from "Adding Todo" is not showing in the ListView . it do take me to the List Activity but without showing the data .
This is How the app going to be "Adding todo"
And this is the ListView where the data should be in it
My code :-
MainActivity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = findViewById(R.id.list_view);
arrayList = new ArrayList<>();
todoAdapter = new TodoAdapter(this , arrayList);
listView.setAdapter(todoAdapter);
}
public void onClick(View view) {
Intent intent = new Intent();
intent.setClass(MainActivity.this, AddTodo.class);
startActivityForResult(intent, Intent_Constants.INTENT_REQUEST_CODE);
}
protected void onActivityResult(int reqCode ,int resultCode , Intent data ){
// here Iam trying to get the data from ADDING TO DO class
if(resultCode == Intent_Constants.INTENT_REQUEST_CODE){
titleText = data.getStringExtra(Intent_Constants.INTENT_TITLE);
priorityText = data.getStringExtra(Intent_Constants.INTENT_PRIORITY);
statusText = data.getStringExtra(Intent_Constants.INTENT_STATUES);
dateText = data.getStringExtra(Intent_Constants.INTENT_DATE);
timeText = data.getStringExtra(Intent_Constants.INTENT_TIME);
todoAdapter.todo.add(new Todo (titleText , statusText ,priorityText ,dateText ,timeText));
}
}
Intent_Constants
public class Intent_Constants {
public final static int INTENT_REQUEST_CODE = 1;
public final static int INTENT_RESULT_CODE = 1 ;
public final static String INTENT_TITLE = "Title";
public final static String INTENT_PRIORITY = "Priority";
public final static String INTENT_TIME = "Time";
public final static String INTENT_DATE = "Date";
public final static String INTENT_STATUES = "Statues";
}
AddTodo class
In this class I find the id then I converted to String
public void saveButton (View view){
Intent intent = new Intent();
intent.putExtra(Intent_Constants.INTENT_TITLE , title);
intent.putExtra(Intent_Constants.INTENT_DATE , date);
intent.putExtra(Intent_Constants.INTENT_TIME , time);
intent.putExtra(Intent_Constants.INTENT_PRIORITY , priority);
intent.putExtra(Intent_Constants.INTENT_STATUES , completed);
setResult(INTENT_RESULT_CODE, intent);
finish();
}
TodoAdapter class
ArrayList<Todo> todo ;
public TodoAdapter(#NonNull Context context, ArrayList<Todo> todo) {
super(context, R.layout.todo_list,todo);
this.todo = todo;
}
public static class ViewHolder {
TextView titleText;
TextView priorityText;
TextView dateText;
TextView timeText;
CheckBox statusBox;
ImageButton edit_image;

ImageButton delet_image;
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
ViewHolder holder = null;
LayoutInflater inflater = LayoutInflater.from(getContext()) ;
View customeView =inflater.inflate(R.layout.todo_list,parent ,false);
holder.titleText.setText(getItem(position).getTitle());
holder.priorityText.setText(getItem(position).getPriority());
holder.dateText.setText(getItem(position).getDate());
holder.timeText.setText(getItem(position).getTime());
holder.statusBox.setChecked(false);
holder.edit_image = customeView.findViewById(R.id.edit_imageView);
holder.open_image = customeView.findViewById(R.id.open_imageButton);
holder.delet_image = customeView.findViewById(R.id.delete_imageView);
holder.edit_image.setImageResource(R.drawable.ic_edit_black_24dp);
holder.open_image.setImageResource(R.drawable.ic_refresh_black_24dp);
holder.delet_image.setImageResource(R.drawable.ic_delete_black_24dp);
return customeView;
}
Todo class
public class Todo {
private String title ;
private String status ;
private String priority ;
private String date ;
private String time ;
public Todo() {
}
public Todo(String title, String status, String priority, String date, String time) {

You can just set a new adapter, I know it isn't best way, but should do the work. Don't create new one, but nulify yours, and initialize it with new data.
#Noura change this
arrayList.add(new Todo(titleText , statusText ,priorityText ,dateText ,timeText));
to
todoAdapter.todo.add(new Todo(titleText , statusText ,priorityText ,dateText ,timeText));
todoAdapter.notifyDataSetChanged();
and at the constructor u need to update your code like below
ArrayList<Todo> todo ;
public TodoAdapter(#NonNull Context context, ArrayList<Todo> todo) {
this.todo = todo
super(context, R.layout.todo_list,todo);
}

When I run this code I get all the list of image give below audio files but, the date of all the audio files are same like 20 Jan 1970 . below the code of AudioActivity.java. I don't know how I can do it if is possible .

Below the code of Adapter.java

Date of all the audio files are same in the list
This is ModalClass.java

this.uri = uri;
}
public Long getDate() {
return date;
}
public void setDate(Long date) {
this.date = date;
}
}
Long dateTime = modelClass.getDate()
You did not post the code for getDate() while there starts your problem.
It problably returns 0 for all files.
And 0 equals 20 Jan 1970.
public class Memo extends AppCompatActivity {
DBHandler dbh;
Notes items;
#Override

getSupportActionBar().hide();
try{

}
catch (Exception ex){

}
display();
}
public void display( ){ //method to display all items in the database
List<Notes> books_list = dbh.getNotes(); ////here i get the list fromm the database
///// i used a custom adapter because i needed it
final myAdapter adapter = new myAdapter(this, books_list); ///creating adapter from

ListView _note_ = findViewById(R.id.list_txt);
_note_.setAdapter(adapter);

#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

Intent i = new Intent(getApplicationContext() ,Note_content.class);
i.putExtra("Note ", Note_content);
i.putExtra("title", title);
i.putExtra("Date", Date);
startActivity(i);
}
});
i have a problem when I try to to get data( only Note) from this activity to another activity, other values(Date and Title) are working, I tried to use toString method in Notes class but it gives null for note
public class Note_content extends AppCompatActivity {
Notes item;
TextView txt_note ,txt_date , txt_title;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_note_content);
txt_title = findViewById(R.id.txt_ntitle);
txt_note = findViewById(R.id.txt_Nnote);
txt_date = findViewById(R.id.txt_Ndate);
Intent i = getIntent();
String note = i.getStringExtra("Note");
String title = i.getStringExtra("title");
String date = i.getStringExtra("Date");
item = new Notes(title,note,date);
txt_note.setText(item.getNote());
//txt_note.setText(note)
txt_date.setText(date);
txt_title.setText(title);
}
this is the second activit, it is not giving any errors but null instead of the note
and this Notes class
public class Notes {
private int id;
private String title;
private String note ;
private String date;
public Notes() {
}
public Notes(String title, String note, String date) {
this.title = title;
this.note = note;
this.date = date;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getNote() {
return note;
}
public void setNote(String note) {
this.note = note;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
#Override
public String toString() {
return this.note+"\n"+title+"\n"+date;
}
}
i.putExtra("Note ", Note_content);
In the above code line, "Note " has an extra space at the end.
I am using Retrofit to fetch and display data to the screen. I want to search users by their id's. I made interface like this :

You are trying to set an integer in the setText function which only accepts String values. Therefore it is giving this error.
Hence you need to convert it into a string using String.valueOf() function.
remove userid.setText(response.body().getId());
add userid.setText(String.valueOf(response.body().getId()));
SetText with integer parameter looks resource with that id : reference
So you should pass an string value to setText()
userid.setText(String.valueOf(response.body().getId()));
So, replacing this line in DetailActivity.java might help you fix the exception :)

Check if the server response is different then null before you do a enhanced for like this:
if(singleBlogPosts!= null) {
for (SingleBlogPosts posts : singleBlogPosts){
Log.d("AnotherSingleView","Please check RESPONSE: "+response.body().toString());
blogTitle.setText(posts.getBlogTitle());
blogSub.setText(posts.getBlogSubtitle());
blogContent.setText(posts.getBlogContent());
// Glide.with(AnotherSingleView.this).load(singlepost.getBlogMedimg()).into(blogPic);
}
}
you question was list iterator,but we can`t see you list use on anywhere,i guess you may be use recyclerView on you data has not get,because get data was asynchronous.try to use data if you can sure it is existing.
i have json to serializable claas then i use it to populate listview, and everything works fine but i want to populate textview on another xml page with one of the serializable object and i read to best way to do it is bundle intent, but i did code something wrong.

Instead use:
public void updateList() {
TextView infoz = (TextView) getView().findViewById(R.id.infoz);
Intent intent = getIntent();
Bundle extras = intent.getExtras();
String title = (String) extras.getSerializable("title");
IF you want to pass any primitive datatyped values (String,int,long,float etc.) then do not need to use Bundle.putExtra(KEY,Serialized Object) and Bundle.getSerializable(KEY). You can use Bundle.putExtra(KEY,primitive data);
If you want to pass class object to intent/bundle then you need to implement Serializable/Parsable in that class like:
public class Test implements Serializable
{
private static final long serialVersionUID = 1L;
int test1;
}
and then you can pass that object instance to intent like:
myIntent.putExtra( KEY, new Test() );
For more clarification check pass seriable object in intent example
