Passing listview array strings to viewtext in another activity

I have a listview activity that displays an array (ml_main) from my custom class (ml_lists) and adapter (ml_my_adapter). The array is added to via another activity. I have a 3rd activity that I want to display the item and subitem in textviews when the appropriate listitem is selected. Its this last part that I am struggling with, my intent opens the 3rd activity but the textviews are empty (dont even appear), any help really appreciated, code below...
package com.example.adam.mylists;
public class ml_lists {
// Store the name of the item
private String mItem;
// Store the name of the subitem
private String mSubItem;
// Constructor that is used to create an instance of the list_my_list object
public ml_lists(String mItem, String mSubItem) {
this.mItem = mItem;
this.mSubItem = mSubItem;
}
public String getmItem() {
return mItem;
}
public void setmItem(String mItem) {
this.mItem = mItem;
}
public String getmSubItem() {
return mSubItem;
}
public void setmSubItem(String mSubItem) {
this.mSubItem = mSubItem;
}

The problem with your code is that you are not assigning values to "item" and "subitem" in your on click listener. They are empty. You can fetch the values of current selected item by passing the selected position to userlist.
Most probably you can do something likes this.
ml_lists selectedItem=userlist.get(i);
item=selectedItem.getmItem();
subItem=selectedItem.getmSubItem();

Sorry if that was a lot of unnecessary code but I'm a beginner here and did not know what you would want to see.
I'm trying to call Collections.sort when the Column Title Textview "Order Date" is clicked. The Data that contains the Customer objects is stored in an SQLite database (not sure if that's pertinent).

You need to write a method in adapter class that should look like this;
public void sort(){
Collections.sort(list, new Comparator<Customer>() {
#Override
public int compare(Customer o1, Customer o2) {
return o1.compareTo(o2);
}
});
notifyDataSetChanged();
}
if you don't want to create comparator every method call you can create variable of comparator.
private Comparator comp = new Comparator<Customer>() {
#Override
public int compare(Customer o1, Customer o2) {
return o1.compareTo(o2);
}
});
in this case you need to change sort method like;
public void sort(){
Collections.sort(list, comp);
notifyDataSetChanged();
}
whenever you want to sort in your activity class you need to call this sort method it will sort your list and update listview.
In your activity class you need to call method like below
adapter.sort();
Also if you want to compare according to other fields. You can create variable as
private int sortType;
You should pass parameter to adapter class.
public void sort(int sortType){
this.sortType = sortType;
Collections.sort(list, comp);
notifyDataSetChanged();
}
and change the comparator field as below
private Comparator comp = new Comparator<Customer>() {
#Override
public int compare(Customer o1, Customer o2) {
switch(sortType){
case 0: //By Name
return o1.getName().compareTo(o2.getName);
break;
case 1:
return o1.getQuantitiy() - o2.getQuantitiy();
break;
case 2:
return o1.compareTo(o2);
break;
default:
return 0;
}
}
});

Populating Spinners using Retrofit 1.9?

Am looking sample program which could dynamically populating Spinner item from server using Retrofit 1.9 but still I couldn't find any sample can someone share if there is any sample regarding this requirement or else share the method.
How it should be done as am new for android bit struggling to find a solution thanks in advance!
Here is my spinneritem class:
public class MySpinnerItem {
public MySpinnerItem(){
}
public MySpinnerItem(String text, Integer value) {
Text = text;
Value = value;
}
public String getText() {
return Text;
}
public void setText(String text) {
Text = text;
}
public Integer getValue() {
return Value;
}
public void setValue(Integer value) {
Value = value;
}
public String Text;
public Integer Value;
}
Here is my spinner adapter:
package first.service.precision.servicefirst;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
import java.util.List;
/**
* Created by 4264 on 25-11-2015.
*/
public class MySpinnerAdapter extends ArrayAdapter<MySpinnerItem> {
private Context context;
private List<MySpinnerItem> objects;
public MySpinnerAdapter(Context context, int resource, List<MySpinnerItem> objects) {
super(context, resource, objects);
this.context = context;
this.objects = objects;
}
#Override
public void add(MySpinnerItem object) {
this.objects.add(object);
}
#Override
public int getCount() {
return objects.size();
}
#Override
public MySpinnerItem getItem(int position) {
return objects.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView label = new TextView(context);
label.setText(objects.get(position).getText());
return label;
}
#Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
TextView label = new TextView(context);
label.setText(objects.get(position).getText());
return label;
}
}

return view;
}
}
My doubt is i have done it using dummy data but i need to bind the json response from the server to my spinner how come i do this.

Below, is a sample for setting the spinner
Spinner spinner = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<String> adapter;
List<String> data;
data = new ArrayList<>();
for (int i = 0; i < 20; i++)
data.add("Data " + (i + 1));
adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, data);
spinner.setAdapter(adapter);
Here data is a dummy data , in your case it will be dummy data.

first create theretrofitapi interface
/**

import java.util.List;

.setEndpoint(ROOT_URL)
.build();
//Creating an object of our api interface
RetrofitInternetApi retrofitInternetApi = restAdapter.create(RetrofitInternetApi.class);
//While the app fetched data we are displaying a progress dialog
final ProgressDialog loading = ProgressDialog.show(getActivity(), "Fetching Data", "Please wait...", false, false);
//Defining the method
retrofitInternetApi.getDepartmentName(new Callback<List<DepartmentNoRealm>>() {
#Override
public void success(List<DepartmentNoRealm> list, Response response) {
//Dismissing the loading progressbar
loading.dismiss();
Log.d("JSON LIST",list.toString());
//Storing the data in our list
departmentNoRealmList = list;
//Calling a method to show the list
showListinSpinner(); }
#Override
public void failure(RetrofitError error) {
//you can handle the errors here
}
});
}
then create a class model
package myafya.safaricom.co.ke.myafya.model.realm;
/**
* Created by 001557 on 1/13/2016.
*/
public class DepartmentNoRealm {
public int departmentID;
public String departmentName;
public String departmentURLimage;
public int getDepartmentID() {
return departmentID;
}
public void setDepartmentID(int departmentID) {
this.departmentID = departmentID;
}
public String getDepartmentName() {
return departmentName;
}
public void setDepartmentName(String departmentName) {
this.departmentName = departmentName;
}
public String getDepartmentURLimage() {
return departmentURLimage;
}
public void setDepartmentURLimage(String departmentURLimage) {
this.departmentURLimage = departmentURLimage;
}
}
now the code showList in Spinner
//Our method to show list
private void showListinSpinner(){
//String array to store all the book names
String[] items = new String[departmentNoRealmList.size()];
//Traversing through the whole list to get all the names
for(int i=0; i<departmentNoRealmList.size(); i++){
//Storing names to string array
items[i] = departmentNoRealmList.get(i).getDepartmentName();
}
//Spinner spinner = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<String> adapter;
adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, items);
//setting adapter to spinner
spinnerDepartments.setAdapter(adapter);
//Creating an array adapter for list view
}
Then SHARE IT AND MAKE IT EASY
MY JSON WAS

TweetAdapter not fetching information from TweetListActivity

I have been taking this Android tutorial at CodeLearn and have faced a problem. I have searched all through the Internet and I can't seem to find any answer for this.
Here's the code for the TweetListActivity:
package com.arvisapps.aryansh.encryptit;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import java.util.ArrayList;
import java.util.List;
public class TweetListActivity extends ListActivity
{
private String[] stringArray;
private ArrayAdapter tweetItemArrayAdapter;
private List<Tweet> tweets;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tweet_list);
tweets = new ArrayList<Tweet>();
for(int i = 0; i < 5 ; i++)
{
Tweet tweet = new Tweet();
tweet.setTitle("Header #" + i);
Log.d("Fuck Me", "Title captured " + tweet.getTitle());
tweet.setBody("Body text #" + i);
tweets.add(tweet);
}
tweetItemArrayAdapter = new TweetAdapter(this, tweets);
setListAdapter(tweetItemArrayAdapter);
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id)
{
Intent intent = new Intent(this, TweetDetailActivity.class);
startActivity(intent);
}
}
Here's the code for TweetAdapter:
package com.arvisapps.aryansh.encryptit;
import android.app.Activity;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
import java.util.List;
public class TweetAdapter extends ArrayAdapter<Tweet> {
String headerSet;
private LayoutInflater inflater;
public TweetAdapter(Activity activity, List<Tweet> tweets) {
super(activity, R.layout.row_tweet, tweets);
inflater = activity.getWindow().getLayoutInflater();
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = inflater.inflate(R.layout.row_tweet, parent, false);
Tweet tweet = new Tweet();
headerSet = tweet.getTitle();
Log.d("Text Captured", "Text Captured "+headerSet);
((TextView)convertView.findViewById(R.id.tweetTitle)).setText(headerSet);
return convertView;
}
}
Here's an additional POJO:
package com.arvisapps.aryansh.encryptit;
public class Tweet
{
private String id;
private String title;
private String body;
public void setTitle(String title)
{
this.title = title;
}
public String getTitle()
{
return this.title;
}
public void setBody(String body)
{
this.body = body;
}
public String getBody()
{
return this.body;
}
public void setId(String id)
{
this.id = id;
}
public String getId()
{
return this.id;
}
}
The problem is that when I check the logcat for TweetListActivity it shows the right text, i.e, the text I need as an output but in TweetAdapter upon checking the Logcat the same text is nullified, i.e, it is displayed as null in the logcat. I want that the text in TweetAdapter to be what it is in the TweetListActivity.

2 column listview within a 2 column list view

i want to put a 2 column listview in the 2nd column of my first 2 column listview but i dont know how to and is it possible to use the same code to make it a 3 column list view?where in the first column is an image and the 2nd and 3rd column are both text i tried it but it has error... my code goes like this..
