Getting only the last item data from hashmap arraylist

Getting only the last item data from hashmap arraylist - android

I have parsed json data in which there is a main json array and it contains sub json array. But the main json array not containing the sub json array in every item. So i have parsed all the data accroding to it. and i am getting perfect data from it. But the problem is that the main json array data is displaying in listview and after click on list view item the sub json array is display accroding to main json array item but its only get the last element of sub json array from hash map array list. So i can't get proper way to display so please find out some standard solution.
Here is My Code

you should have to put new HashMap inside your current HasHMap so you can get subcategories items for particular index.
see this for how to use nested HashMap? and use it in subcategories loop.
i am using ArrayList of getter setter class to bind the data. so if you can convert your code into arraylist and edit the question that will be a great..
and see below code

Trying to put a search functionality in my application

Hi, guys! First of all, I'm newbie! I'm trying to create a search functionality (Search BY CITY) in my application. But something is wrong! It don't work!
The error message is: 'The method filter(String) is undefined for the type BinderData'
adapter.filter(text);
Could someone help me in details? I included the "TextWatcher" function in my main activity (WeatherActivity).
This is my code:

How to add search functionality in custom listview

I have a problem to add search function in a listview in my simple android app. I was followed this article [https://workspaces.codeproject.com/vatsag/customized-android-listview-with-image-and-text][1], but i can't figure how to add search functionality.

How can I proceed in these two scenarios?
EventParsingClass EPSP= ??? and
EPSP.getid= ??

fetch[0]="XXX"
fetch[1]="YYY"
fetch[2]="ZZZ"
lv.setOnItemClickListener(MainActivity.this);
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
Toast.makeText(getApplicationContext(), fetch[position] + "Clicked",
Toast.LENGTH_LONG).show();
}
just declare fetch[position] to get the value of clicked item. hope this will give you some solution.

Use int position to find out values from your data list (array list or what ever you used).
lv.setOnItemClickListener(MainActivity.this);
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
Toast.makeText(getApplicationContext(), EPSP.getid(position) + "Clicked",Toast.LENGTH_LONG).show();
}

EventItem item = (EventItem) parent.getItemAtPosition(position);
Now you have a hold of EventItem. So you can start using the get methods of your EventItem class in order to get whatever you want from it.

I got the solution:
EventParsingClass new_method(int value) {
int item_count = 0;
for (int i = 0; i < arrayOfEventDescription.size(); i++) {
ArrayList<EventParsingClass> Arraylist_for_loop = arrayOfEventDescription
.get(i);
item_count++;
for (int j = 0; j < Arraylist_for_loop.size(); j++) {
if (value == item_count) {
return Arraylist_for_loop.get(j);
}
item_count++;
}
}
return null;
}
And call it from here:
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
EventParsingClass newObject = new_method(arg2);
if (newObject == null) {
} else {
Log.d("Generated Value Id : ", "" + newObject.getId());
Toast.makeText(getApplicationContext(),
"Item Clicked" + arg2 + "-----" + newObject.getTitle(),
Toast.LENGTH_LONG).show();
}
}

Missing data in Section list view in Android?

I am working with Section list view in Android to show Call details according to date.
Means under a particular date number of call details. But when I get 2 calls under the same date, the last date is visible only and the list does not show the rest of the calls of that date.
Calls under different dates are shown correctly but calls under same date are not shown correctly, only the last call is shown.
I am using the below code:

because you are getting all titles inside model_Inserts List you will need to pass this List to Custom BaseAdapter for showing in TextView as :
Change ShowAllContent() method as:
public void ShowAllContent() {
GridView gridView1 = (GridView) findViewById(R.id.grid_all);
gridView1.setAdapter(new ImageAdapter(TopActivity.this, placeList,model_Inserts));
}
and ImageAdapter constructor as :
public class ImageAdapter extends BaseAdapter {
private ArrayList<HashMap<String, String>> MyArr =
new ArrayList<HashMap<String,String>>();
List<Model_Insert> model_Inserts=null;
public ImageAdapter(Context c,
ArrayList<HashMap<String, String>> myArrayList,
List<Model_Insert> model_Inserts){
context = c;
MyArr = myArrayList;
this.model_Inserts=model_Inserts;
}
///your code here...
now use model_Inserts for getting Title to show inside getView
