How can i do it?
I am filling spinner here

for (int i = 0; i < cityArrayList.size(); i++) {
cityList.add(cityArrayList.get(i).getCinemaCity());

I'd create a method to update the adapter once an item on your spinner is chosen:
cityspinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,int position, long id) {
city = (String) parent.getItemAtPosition(position);
resetCinema(city); //or onRestart();
}
public void onNothingSelected(AdapterView<?> parent){
}
});
And resetCinema(city) rechages the view depending on the city value. You can do this manually:
public void resetCinema(String city) {
//show list view elements depending on city
}
or just call a refresh of the whole Activity:
protected void onRestart() {
Intent refresh = new Intent(this, Main.class);
startActivity(refresh);//Start the same Activity
finish(); //finish Activity.
}

I suggest you to call
adapter2.notifyDataSetChange();
But anyway there is no need to initialize a new adapter every time.
you should create a method inside the adapter like this:
public void setMyArray(ArrayList<Cinema> items) {
myArray.clear();
myArray.addAll(items);
notifyDataSetChange();
}

It seems the values are not really being overwritten. Each time the second activity is loaded new part and type ArrayLists are being created. In these new lists only the latest part and type are added (in the onCreate Function) which have travelled with the intent.
If you want the list to keep adding the part and type selected by the user you can maintain the lists on the MainActivity. So upon selection of each item and type add it to the list on the MainActivity and then pass it to the ListViewItems activity.
This way the list will always have all the items selected by you.
I must admit I am not 100% sure if I understood your question correctly. But I have tried to answer with as much as I did.

Custom BaseAdapter wont add new Data - Android

I have a custom baseadapter that creates comment boxes. Everything works great on it until I want to add data. When I try to add the data it deletes the previous data and adds the new data. How do I make it so it keeps all the data? Is my Add method incorrect? Here is my baseadapter,
class CreateCommentLists extends BaseAdapter{
Context ctx_invitation;
String[] listComments;
String[] listNumbers;
String[] listUsernames;
public CreateCommentLists(String[] comments, String[] usernames, String[] numbers, DashboardActivity context)
{
super();
ctx_invitation = context;
listComments = comments;
listNumbers = usernames;
listUsernames = numbers;
}
#Override
public int getCount() {
if(null == listComments)
{
return 0;
}
// TODO Auto-generated method stub
return listComments.length;
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return listComments[position];
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View v = null;
try
{
String inflater = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater li = (LayoutInflater)ctx_invitation.getSystemService(inflater);
v = li.inflate(R.layout.list_item, null);
TextView commentView = (TextView)v.findViewById(R.id.listComment);
TextView NumbersView = (TextView)v.findViewById(R.id.listNumber);
TextView usernamesView = (TextView)v.findViewById(R.id.listPostedBy);
Button usernameButton = (Button)v.findViewById(R.id.listUsernameButton);
Button numberButton = (Button)v.findViewById(R.id.listNumberButton);
commentView.setText(listComments[position]);
NumbersView.setText(listNumbers[position]);
usernamesView.setText(listUsernames[position]);
usernameButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent i = new Intent(getApplicationContext(), ProfileActivity.class);
i.putExtra("usernameOfProfile",listUsernames[position]);
startActivity(i);
finish();
}
});
numberButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
Intent i = new Intent(getApplicationContext(), ProfileActivity.class);
i.putExtra("NumberProfile",listNumbers[position]);
startActivity(i);
finish();
}
});
}
catch(Exception e)
{
e.printStackTrace();
}
return v;
}
public void add(String[] comments, String[] usernames,
String[] numbers) {
listComments = comments;
listNumbers = usernames;
listUsernames = numbers;
}
public int getCount1() {
if(null == listComments)
{
return 0;
}
// TODO Auto-generated method stub
return listComments.length;
}
public Object getItem1(int position) {
// TODO Auto-generated method stub
return listComments[position];
}
public long getItemId1(int position) {
// TODO Auto-generated method stub
return 0;
}
public View getView1(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View v = null;
try
{
String inflater = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater li = (LayoutInflater)ctx_invitation.getSystemService(inflater);
v = li.inflate(R.layout.list_item, null);
TextView commentView = (TextView)v.findViewById(R.id.listComment);
TextView NumbersView = (TextView)v.findViewById(R.id.listNumber);
TextView usernamesView = (TextView)v.findViewById(R.id.listPostedBy);
Button usernameButton = (Button)v.findViewById(R.id.listUsernameButton);
Button numberButton = (Button)v.findViewById(R.id.listNumberButton);
commentView.setText(listComments[position]);
NumbersView.setText(listNumbers[position]);
usernamesView.setText(listUsernames[position]);
usernameButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent i = new Intent(getApplicationContext(), ProfileActivity.class);

i.putExtra("NumberProfile",listNumbers[position]);
startActivity(i);
finish();

return v;
}
}
Setting the adapter:
final CreateCommentLists mycmlist = new CreateCommentLists(comments, usernames, numbers, DashboardActivity.this);
lstComments = (ListView)findViewById(android.R.id.list);
lstComments.setAdapter(mycmlist);
This is what how I call the add method,
mycmlist.add(comments,usernames,numbers);
mycmlist.notifyDataSetChanged();

In your add method you're setting the arrays to new values listComments = comments; That's replacing your old data with the new data.
You could use System.arrayCopy() to resize your listArrays to the new size and append the new items. A much less tedious approach, however, would be to store your arrays as List<String>, allowing you to add more items without worrying about resizing lists.
The result would look something like this...
public class CommentsAdapter extends BaseAdapter
{
private LayoutInflater inflater;
private List<String> comments;
private List<String> numbers;
private List<String> usernames;
public CommentsAdapter(Context context)
{

I also highly recommend reading this page on the Android Developer's site: http://developer.android.com/training/improving-layouts/smooth-scrolling.html
Your current adapter implementation is very inefficient, and that page should help you iron out some kinks.

You probably need to add the String[] array to the existing one, instead of replacing it.
Add this function which joins two arrays (Sadly there is no already-implemented method for Java):
String[] concat(String[] A, String[] B) {
String[] C= new String[A.length + B.length];
System.arraycopy(A, 0, C, 0, A.length);
System.arraycopy(B, 0, C, A.length, B.length);
return C;
}

And then change the add method to this:
public void add(String[] comments, String[] usernames,
String[] numbers) {
listComments = concat(listComments, comments);
listUsernames = concat(listUsernames, usernames);
listNumbers = concat(listNumbers, numbers);
}
And you had a typo in your code. In the add method, the listUsernames and listNumbers should be swapped I think.. I fixed it for you.

How to assign different values to buttons in a listView - Android

I have a ListView Item that has 2 buttons in it. There are multiple ListView items so there are many buttons. How can I assign a different value to each button? What I want to happen is every button leads to the same activity, but when it goes to the new activity it sends a value that the button was assigned. Then the activity can handled the value. I want the values assigned to the buttons to be the same as what the text is set to, here is my baseAdapter
class CreateCommentLists extends BaseAdapter{
Context ctx_invitation;
String[] listComments;
String[] listNumbers;
String[] listUsernames;
public CreateCommentLists(String[] comments, String[] usernames, String[] numbers, DashboardActivity context)
{
super();
ctx_invitation = context;
listComments = comments;
listNumbers = usernames;
listUsernames = numbers;
}
#Override
public int getCount() {
if(null == listComments)
{
return 0;
}
// TODO Auto-generated method stub
return listComments.length;
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return listComments[position];
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View v = null;
try
{
String inflater = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater li = (LayoutInflater)ctx_invitation.getSystemService(inflater);
v = li.inflate(R.layout.list_item, null);
TextView commentView = (TextView)v.findViewById(R.id.listComment);
TextView NumbersView = (TextView)v.findViewById(R.id.listNumber);
TextView usernamesView = (TextView)v.findViewById(R.id.listPostedBy);
Button usernameButton = (Button)v.findViewById(R.id.listUsernameButton);
Button numberButton = (Button)v.findViewById(R.id.listNumberButton);
commentView.setText(listComments[position]);
NumbersView.setText(listNumbers[position]);
usernamesView.setText(listUsernames[position]);
usernameButton.setText("Go to " + listUsernames[position]);
numberButton.setText("Go to " + listNumbers[position]);
}
catch(Exception e)
{
e.printStackTrace();
}
return v;
}
}

usernameButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(CurrentActivity.this, TargetActivity.class);
intent.putExtra("param", listUsernames[position]);
startActivity(intent);
}
});
}

My ListView consist an ImageView and a TextView i need to get the Text from the TextView

My ListView consist an ImageView and a TextView I need to get the Text from the TextView.

When you add things to the list, you can add hashmaps to the arraylist which the adapter looks at. Then you can grab the values which are name value pairs.

I think you want to get the position of the list you clicked, Its simple you can use OnItemClickListener as follows
YourList.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
int position=arg2;
// where position is the clicked position
} }
If you stored your data in String array pass this position say array[position] to string array you can get the Text..
