i am a beginner so i hope i would get sufficient help from it.

So it appears you have not attempted to add a listener to your ListView. You can do this via AdapterView.OnItemClickListener
listView.setOnItemClickListener(new AdapterView.OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id){
//.. launch your new activity here using Intent
Intent intent = new Intent(MainActivity.this, NewActivity.class);
startActivity(intent);
}
});
Another note, you should really get better at naming your classes. Recommended reading: Effective Java
You should also read: Making a listview scroll smooth which talks about the ViewHolder pattern, or simply move to a RecyclerView once you know a bit more android.

Android Studio Radio button save state in listview fetched from sqlite

So i have an application where i fetched some poll from an sqlite db and used them in listview and now i tried to add a radio button but when i hit a button back that i created it doesn't save the choice i did from the radio button.

i remind you that i did a database connection with an external database
it's really frustrating i couldn't find something similar and i can't solve this please help.
p.s. for any mistakes...i am really new in java and android studio in general.

Updating an ArrayAdapter from inside an onClickListener in getView

I am making a shopping cart app where users can add and remove items from the cart. When a user views their cart, a list of items they have added appear. This list is made using an ArrayAdapter. Each row contains a remove button where the user can remove the item from the cart. I have successfully been able to remove the item from the Cart object. However, I am running into trouble when it comes to updating the screen when the user clicks the remove button. I have heard of the notifydatasetchanged() method for adapters, but I am not sure how to implement that from inside the OnClickListener in getView. Here is the code:
CartScreen.java
package com.livilatenight.livilatenight;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ListView;
import android.widget.Toast;
import com.parse.ParseException;
import com.parse.ParseUser;
import com.parse.SaveCallback;
public class CartScreen extends ActionBarActivity {
ListView items;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cart_screen);
final ParseUser current = ParseUser.getCurrentUser();
try{
Cart userCart = (Cart) current.fetchIfNeeded().get("cart");
String[] itemNames = userCart.getItems();
String[] itemPrices = userCart.getPrices();
int[] quantities = userCart.getQuantities();
Integer[] itemPictures = userCart.getPictures();
CartListAdapter adapter = new CartListAdapter(CartScreen.this, itemNames,itemPrices,quantities,itemPictures);
items = (ListView) findViewById(R.id.listView);
items.setAdapter(adapter);
}catch(ParseException e){
Toast.makeText(CartScreen.this, e.toString(),Toast.LENGTH_LONG).show();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_cart_screen, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
CartListAdapter.java
package com.livilatenight.livilatenight;
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Spinner;

public class CartListAdapter extends ArrayAdapter<String> {

public CartListAdapter(Activity context, String[] itemnames, String[] prices, int[] quantities, Integer[] pictures) {

}
public View getView(final int position,View view,ViewGroup parent) {

View rowView=inflater.inflate(R.layout.cart_item, null,true);
TextView itemName = (TextView) rowView.findViewById(R.id.tvItemName);
TextView itemPrice = (TextView) rowView.findViewById(R.id.tvPrice);
ImageView itemPicture = (ImageView) rowView.findViewById(R.id.ivItemPicture);
View blankView = (View) rowView.findViewById(R.id.blankView);
Button removeCart = (Button) rowView.findViewById(R.id.btnRemoveCart);
final Spinner spinner = (Spinner) rowView.findViewById(R.id.spinnerQty);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(context, R.array.spinner_numbers, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setSelection(quantities[position]-1);
itemName.setText(items[position]);
itemPrice.setText(prices[position]);
itemPicture.setImageResource(pictures[position]);
removeCart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ParseUser current = ParseUser.getCurrentUser();
int quantity = spinner.getSelectedItemPosition()+1;
Cart userCart = (Cart) current.get("cart");
boolean success = userCart.removeFromCart(items[position]);
if(success){
Toast.makeText(getContext(), "Removed from Cart", Toast.LENGTH_LONG).show();
}else{
Toast.makeText(getContext(), "Item is already in your shopping cart", Toast.LENGTH_LONG).show();
}
current.saveInBackground();
}
});
return rowView;
};
}
I want to update the cart list when a user clicks the removeCart button. How could I do this?
UPDATE
I did a workaround where I just set a new adapter each time an item is removed. Not what I wanted to do but it works so I'll keep it the way it is.

try this
if (success) {
Toast.makeText(getContext(), "Removed from Cart", Toast.LENGTH_LONG).show();
final String s = items[position];
List<String> list = new ArrayList<String>(Arrays.asList(items));
list.remove(s);
items = list.toArray(array);
this.notifyDataSetChanged()
}

In your custom adapter call this.notifyDataSetChanged(); where you are performing delete functionality and deleting that element from arrayList which is set to that adapter.
You have to remove that record from the ArrayList too that you have set to your adapter if you know which record it is you can use ArrayList.remove(index); and then use notifyDataSetChanged();
EDIT:
Go to your adapter and add a method delete();
public void delete(int position){
data.remove(position);
notifyItemRemoved(position);
}
In your onClick(); method add this:
delete(getPosition());

Here is the solution that worked in my case.
In your CartListAdapter override remove method of Array Adapter.
#Override
public void remove(String var){
// Call your utility methods you defined to delete the item
// Notify ListView that their is a change
notifyDataSetChanged();
}
Make the following changes in your Click Listener
removeCart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Call this.remove(var) with String you want to delete
}
});
notifyDataSetChanged() works only in case of add(), insert(), remove(), and clear(). Read this

So first of all register your listView for a context menu in the onCreate method:
registerForContextMenu(yourListView);
Create the contextmenu by overridig the onCreateContextMenu:
#Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo)
{
AdapterContextMenuInfo info = (AdapterContextMenuInfo) menuInfo;
_listPosition = info.position; // Get Index of long-clicked item
super.onCreateContextMenu(menu, v, menuInfo);
menu.setHeaderTitle("Choose Action"); // Context-menu title
menu.add(0, v.getId(), 0, "Edit"); // Add element "Edit"
menu.add(0, v.getId(), 1, "Delete"); // Add element "Delete"
}
React on clicks in context-menu:
#Override
public boolean onContextItemSelected(MenuItem item)
{
if(item.getTitle() == "Edit") // "Edit" chosen
{
// Do stuff
}
else if(item.getTitle() == "Delete") // "Delete" chosen
{
// Do stuff
}
else
{
return false;
}
return true;
}

Next time just spend few minutes and google it yourself:
http://developer.android.com/guide/topics/ui/menus.html#context-menu
http://www.stealthcopter.com/blog/2010/04/android-context-menu-example-on-long-press-gridview/
Override onCreateContextMenu() to create the menu and onContextItemSelected() to handle the click event
You also need to register listView for the contextual menu. You can do it in fragment's onActivityCreated() method:
registerForContextMenu(listView);

You have to register your custom ListView with Context Menu. Use Method registerForContextMenu(listView); . Call this method in onCreate

I would define the onLongClickListener in the getView() method of your overriden ArrayList extension. Just register the view inside the long click listener, using registerForContextView(convertView).
Now in your Activity code, simply define the context menu as you would in any other case:
#Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
...
menu.setHeaderTitle(...);
menu.add(...);
}
#Override
public boolean onContextItemSelected(MenuItem item) {
final int mId = item.getItemId();
switch (mId) {
case 0:
...
break;
default:
break;
}

More precision:
#Override
public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
TreeViewList v1=(TreeViewList) v; //my custom listview
AdapterContextMenuInfo info = (AdapterContextMenuInfo) menuInfo;
final LinearLayout viewLayout = (LinearLayout) v1.getChildAt(info.position-v1.getFirstVisiblePosition());//if in list many items
final TextView descriptionView = (TextView) viewLayout
.findViewById(R.id.list_item_description);
menu.add(0, v.getId(), 0, descriptionView.getText());
menu.add(0, v.getId(), 0, "Action 2");
}

DialogFragment created by an event from a button in a custom ArrayAdapter always has same position

I'm a newb so try to be patient with me
Here is some background information about the problem I am having:
I have a fragment, ViewFragment, that consists of two components: a Spinner and a ListView. The Spinner is a default Spinner with a regular ArrayAdapter that fills the Spinner with values taken from an ArrayList called "metaList" that is basically and ArrayList of objects that each themselves have an ArrayList called "mainList".
The ListView has the custom ArrayAdapter (called "CustomAdapter") I mentioned in the title. The CustomAdapter fills the ListView with values taken from the "mainList" of the selected item in the Spinner.
Now, the CustomAdapter for the ListView has two buttons. The only button that does anything yet (called "viewButton") creates a DialogFragment when pushed.
The problem I am having relates to this DialogFragment. Each item in the ListView should create a unique DialogFragment when its viewButton is pressed. However, regardless of which item in the ListView has its button pressed, the DialogFragment is always the same and displays the DialogFragment for the last item in the ListView.
I think that this problem is due to the fact that the ListView items themselves are not being pressed, only their buttons, so the position value in the getView() method for the CustomAdapter never really changes.
How do I fix this problem?
Here is the code for the ViewFragment that contains the Spinner and ListView components:
package com.statbot;

for(int k = 0; k < MainActivity.metaList.size(); k++)
{
names.add(MainActivity.metaList.get(k).getName());
}
ArrayAdapter<String> adapter = new ArrayAdapter<String> (container.getContext(),android.R.layout.simple_spinner_item, names);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

and here are some screenshots to make things easier to understand. The spinner is at the top with the ListView directly below it. The first number of each ListView item is its position, and the second number is the position of the Spinner. The button of interest is the paper-shaped one. ignore the pencil, it doesn't do anything yet.
and here is a DialogFragment. The title is the Spinner position and the bottom number is the position of the item whose button was pushed, but notice that even though the 1st item on the ListView had its button pushed to display this dialog, the number at the bottom of the fragment displays a three for the 4th item.
Any help on this problem would be greatly appreciated, this is one of the last major hurdles I need to overcome for this project, everything else should be pretty basic.
Thanks!

In your showContents(), you completely ignore the two parameters passed in and instead use this.pos, which would indeed be the position of the last view inflated by the ListView. Just use your parameters (and set up your IDE to warn you about unused variables and parameters).
On a different note, passing data to a fragment like this would not survive configuration changes (unless you have setRetainInstance everywhere, but that's riddled with different sorts of problems). Consider using setArguments, serializing state in onSaveInstanceState and deserializing it in onCreate (using getArguments or savedInstanceState, if that's available).
