Second AlertDialog list item click based on the first Alertdialog list android

In my android app, I need to generate one Alertdialog with a list of Company name. For example Company 1, Company 2, Company 3. Now if the user cllick company 1, he will get second alertdialog which will show some actions. Like Phone Call, Email, etc. Now I have implemented this two alertdialog in my code. But what I want to do, that for each company there should be different Phone number and email adress. So Far I have tried with same number with all the company. But in real in real if user click company 1, he will get the second alert list of action with phone call, email. if he clicks phone option he will see the phone number company 1, if he clicks company 2, he will get alertoption with phone number of company 2. But I am very new in developing area. I know there is something with Mapping topic, by which I can do it easily but I am not getting actually how to proceed with it. My code is like this
public List<CompanyDetail> setCompanydata(){
int n = 3;
private List<CompanyDetail> companyDetailList = new ArrayList<CompanyDetail>(); //modifier private is not allowed here
private HashMap<String, List<CompanyDetail>> companyContactDetail = new HashMap<String, List<CompanyDetail>>(); //modifier private is not allowed here
for(int i=0;i<n;i++){
private CompanyDetail comD= new CompanyDetail(); //modifier private is not allowed here
comD.setcompanyPhoneNo(companyPhoneno); //cannot resolve problem companyPhone
comD.setcompanyEmail(compnayEmailId);
companyDetailList.add(comD);
companyContactDetail.add(companyname, companyDetailList);//cannot resolve method 'add(?,java util list..
}
return companyContactDetail; //incompatible type
}
private List<CompanyDetail> companyDetailList;
private HashMap<String, List<CompanyDetail>> companyContactDetail = new HashMap<String, List<CompanyDetail>>();
companyContactDetail = setCompanydata(); //unknown class company contact deatil
private void showFirstDialogwithList() {
//Create a new builder and get the layout.
final AlertDialog.Builder builder = new AlertDialog.Builder(this.getActivity());
LayoutInflater inflater = this.getActivity().getLayoutInflater();
View dialogView = inflater.inflate(R.layout.first_alertlist_contact, null);
builder.setView(dialogView);
builder.setCancelable(true);
//Show the dislog
final AlertDialog alert = builder.show();
//Get the TextView, ListView, Button from the layout.
TextView alertTitle = (TextView) dialogView.findViewById(R.id.title);
Button alertButton = (Button) dialogView.findViewById(R.id.cancel_button);

// Defined Array values to show in ListView

builder.setTitle("+1234667");
builder.setPositiveButton("Call", new DialogInterface.OnClickListener() {

dialog.dismiss();
}
});

alert.show();
}
if (itemPosition == 1) {
alert.dismiss();
......;
}
if (itemPosition == 2) {
dismiss();
showEmail();
}
if (itemPosition == 3) {
dismiss();
}
}
});
}
My string arrays are
<string-array name="company_name">
<item>company 1</item>
<item>Company 2</item>
<item>Company 3</item>
</string-array>
<!-- AlertDialog way of Contact array -->
<string-array name="contact_way">
<item>Phone Call</item>
<item>Email</item>
</string-array>
<String-array name="phone">
<item>123456</item>
<item>125658</item>
<item>123451</item>
</String-array>
<String-array name="email">
<item>email1</item>
<item>email2</item>
<item>email2</item>
</String-array>

you can pass the position for the item and test it at your function or you can pass it directly :
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
alert.dismiss();
showSecondDialogwithList(position);
}
private void showSecondDialogwithList(int position) {
String phoneNumber;
switch (position) {
case 1:
phoneNumber = "123";
break;
case 2:
phoneNumber = "456";
break;
case 3:
phoneNumber = "789"
}
final AlertDialog.Builder builder = new AlertDialog.Builder(this.getActivity(), R.style.DialogStyle);
LayoutInflater inflater = this.getActivity().getLayoutInflater();

To go deep in to logic behind that kind of scenario best way to use *HashMap*.
according to your scenario. i change in your code check it out:
public class CompanyDetail{
String companyPhoneNo;
String companyEmail;
public void setcompanyPhoneNo(String phoneNo){
this.companyPhoneNo = phoneNo;
}
public void setcompanyEmail(String Email){
this.companyEmail = Email;
}
public String getcompanyPhoneNo(){
return companyPhoneNo;
}
public String getcompanyEmail(){
return companyEmail;
}
}
public HashMap<String, List<CompanyDetail>> setCompanydata(){
int n = 3;
private List<CompanyDetail> companyDetailList = new ArrayList<CompanyDetail>();
private HashMap<String, List<CompanyDetail>> companyContactDetail = new HashMap<String, List<CompanyDetail>>();
for(int i=0;i<n;i++){
CompanyDetail comD= new CompanyDetail();
comD.setcompanyPhoneNo(companyPhoneno);
comD.setcompanyEmail(compnayEmailId);
companyDetailList.add(comD);
companyContactDetail.add(companyname, companyDetailList);
}
return companyContactDetail;
}
private List<CompanyDetail> companyDetailList;

It's not a good practice to display two dialogs one by one. Of course you can implement it, like described above, but it will be much better to display separated activity(fragment) with the list(ListView, RecyclerView) of companies and click on each item will show the dialog with needed params. It will look better from design side and users experience.

Android insert LinearLayout Views programmatically in OnCreate not showing

i'm trying to add several LinearLayouts with 2 Buttons and one Spinner. If i add this LinearLayout by clicking a button in the activity it works perfect, but if i want the activity to add this like two or three times in calling the method in the onCreate Method, nothing will shown.
Here's my Code:
private void insert() {
ll = new LinearLayout(this);
spinner = new Spinner(this);
ArrayAdapter<CharSequence> adapter;
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
Button badd = new Button(this);
badd.setText("+");
Button bdel = new Button(this);
bdel.setText("-");
ll.addView(bdel);
ll.addView(spinner);
ll.addView(badd);
scrollerLL.addView(ll);
}

My Code works. The Views were added right but in another method i deleted them directly after the initialization, so my own fail :P

You need to set LayoutParameters to your LinearLayout as well as Buttons.
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
ll..setLayoutParams(params);
and same for buttons.
LayoutParams BtnParams = new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
badd.setLayoutParams(BtnParams);
bdel.setLayoutParams(BtnParams);
I hope this will help you out.

Remove item from another activity using button

The problem: I want to remove a item from my listview using a button in another activity.
I have tried several kinds of code, but it just doesn't seem to work.
Right know I use serializable to bundle the object to the other activity.
But I don't know how to remove it, from the other activity.
Can anybody help me with that?
Can I use the button from the second activity, in the first activity to delete the item from the listview?
Class A where I got my ListView
public class ListActivity extends Activity {
ListView list;
Button exit;
SimpleAdapter adapter;
final List<Map<String, String>> data = new ArrayList<Map<String, String>>();

// Name of the truck drivers
final String[] subtitle = new String[] { "Peter Lund", "Hans Larsson",

}
Class B where I got my accept button.
When I click accept, the item from the listview in Class A should be removed.
public class InformationActivity extends Activity {

//Remove item
accept.setOnClickListener(new OnClickListener() {

}

You should not directly remove the item from the view, but from the data displayed in it.
For example if your ListView is displaying items from an ArrayList, just remove the item in the ArrayList from you Activity B, and call myAdapter.notifyDataSetChanged() when back in the Activity A, which contains the adapter.
You can remove items by accessing to the ArrayList or by overriding the remove() method if you have only access to the adapter (assuming your adapter extends ArrayAdapter).
Also, you may have to override usefull Adapter methods like getCount(), getView()...

Thanks to all.
I found another solution thanks to remove row from another activity
Class A
public class ListActivity extends Activity {
ListView list;
Button exit;
static List<ListItems> items = new ArrayList<ListItems>();
public static int deletePos;
static ListAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
list = (ListView) findViewById(R.id.list);
exit = (Button) findViewById(R.id.btnExit);
// Registration numbers

Disabling CheckBox in MultiChoiceItems AlertDialog

I have an AlertDialog which it has dynamic items linked to a Cursor from database , it works fine but i wanted to disable user interaction with that because it's an informational dialog , i've disabled my dialog with :
alert.getListView().setEnabled(false);
but the problem is when Items in the list are bigger than the dialog height , because of disabling it's ListView, Scrolling is disabled too and some items doesn't show up, i've tried some links like : Android : How to disable CheckBox in AlertDialog?
with no success. i've also tried :
builder.setMultiChoiceItems(mDBAdapter.instance.getName(SupervisorGuid)
, SyncDBHelper.instance.SentSupervisors(SupervisorGuid),new DialogInterface.OnMultiChoiceClickListener() {
#Override
public void onClick(DialogInterface dialog, int which,
boolean isChecked) {
if(isChecked==true)
{
((AlertDialog) dialog).getListView().setItemChecked(which, false);
}
else
{
((AlertDialog) dialog).getListView().setItemChecked(which, true);
}
}});
AlertDialog alert = builder.create();
Does anybody know a better way to disable the checkboxes without a Custom dialog?
Thanks in Advance.

this may give you some idea...
private void showDialog() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
ArrayList<String> arrayList = new ArrayList<String>();
ArrayList<Boolean> selectedList = new ArrayList<Boolean>();
for (int i = 1; i <= 20; i++) {
arrayList.add("" + i);
selectedList.add(i % 2 == 0);
}
builder.setAdapter(new MyAdapter(arrayList, selectedList), null);
builder.show();
}
public static class MyAdapter extends BaseAdapter {
private ArrayList<String> arrayList;
private ArrayList<Boolean> selectedList;
public MyAdapter(ArrayList<String> arrayList,
ArrayList<Boolean> selectedList) {
this.arrayList = arrayList;
this.selectedList = selectedList;
}
#Override
public int getCount() {
return arrayList.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
return getView(parent.getContext(), position);
}
private RelativeLayout getView(Context context, int position) {
RelativeLayout relativeLayout = new RelativeLayout(context);
AbsListView.LayoutParams params = new AbsListView.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
relativeLayout.setLayoutParams(params);
TextView textView = new TextView(context);
textView.setText(arrayList.get(position));
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
layoutParams.addRule(RelativeLayout.CENTER_VERTICAL);
layoutParams.leftMargin = 30;
textView.setLayoutParams(layoutParams);
relativeLayout.addView(textView);
CheckBox checkBox = new CheckBox(context);
layoutParams = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
layoutParams.rightMargin = 30;
checkBox.setLayoutParams(layoutParams);
checkBox.setClickable(false);
if (selectedList != null) {
checkBox.setChecked(selectedList.get(position));
}
relativeLayout.addView(checkBox);
return relativeLayout;
}
}

I had the same problem and solved it this way:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
...
builder
.setTitle(...)
.setMultiChoiceItems(cursor, IS_CHECKED, LABEL, new DialogInterface.OnMultiChoiceClickListener() {
#Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
((AlertDialog)dialog).getListView().setItemChecked(which, /* assign here the original boolean value of the item */);
}
})
...
AlertDialog dialog = builder.create();
dialog.show();
In summary, when you click the item in the list, just set its value back to the original boolean value.

you can define your check box value with boolean array
"checkValues" is our boolean array which defines which check box should tick or which not. check below ex.
builder.setMultiChoiceItems(dialogList, checkedValues)
private fun showDialog() {
val dialogList: Array<String> = days
val checkedValues = BooleanArray(days.size)
checkedValues[viewpager.currentItem] = true
val builder: AlertDialog.Builder = AlertDialog.Builder(activity)
builder.setTitle("You can copy"+dialogList[viewpager.currentItem]+" time slot to:")
builder.setMultiChoiceItems(dialogList, checkedValues)
{ dialog, which, isChecked ->
(dialog as AlertDialog).listView.setItemChecked(yourIndex, true)
}.setPositiveButton("OK") { dialog, id ->
dialog.dismiss()
}.setNegativeButton("Cancel") { dialog, id ->
dialog.dismiss()
}.show()
}

Get the position of view in LinearLayout (Android)

A had a custom ListView recently. Then I had to display all the list items without scrollbar. Following the method to place items in LinearLayout I changed my code but I can't bind onClickListener to new layout. In ListView I used position var to determine what view was touched. But in LinearLayout onClick callback hasn't position parameter.
Here is my BasketActivity.class:
package ru.**.**;
public class BasketActivity extends Activity {
ArrayList<Item> items = new ArrayList<Item>();
SQLiteDatabase database;
Map<String, ?> all;
ItemAdapter adapter;
Item item2delete;
View deletingView;
private SharedPreferences settings;
private SharedPreferences settings2;
private Basket basket;
TextView basketSum;
private int position2delete;
private Map<String, ?> all2;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_basket);
<..cutted..>
settings = getSharedPreferences("basket", 0);
settings2 = getSharedPreferences("price", 0);
basket = new Basket(settings, settings2);
all = basket.getList();
LinearLayout l1 = (LinearLayout) findViewById(R.id.l1);
MyDBAdapter myDBAdapter = new MyDBAdapter(getBaseContext());
myDBAdapter.open();
Cursor itemCursor = myDBAdapter.getItemsInBasket(all);
while (itemCursor.moveToNext()) {
String[] columns = itemCursor.getColumnNames();
StringBuilder sb = new StringBuilder();
for (int i = 0; i < columns.length; i++) {
sb.append(columns[i]);
}
Item item = new Item();
item.setId(itemCursor.getString(0));
item.setArticul(itemCursor.getString(MyDBSchema.ITEM_ARTICUL));
item.setTitle(itemCursor.getString(MyDBSchema.ITEM_TITLE));
item.setPrice(itemCursor.getInt(MyDBSchema.ITEM_PRICE));
item.setPic80(itemCursor.getString(MyDBSchema.ITEM_PIC80));
item.setPic300(itemCursor.getString(MyDBSchema.ITEM_PIC300));
item.setMessage(itemCursor.getString(MyDBSchema.ITEM_MESSAGE));
item.setColor(itemCursor.getString(MyDBSchema.ITEM_COLOR));
item.setColorpos(itemCursor.getString(MyDBSchema.ITEM_COLORPOS));
items.add(item);
}
itemCursor.close();
myDBAdapter.close();
for (int position=0; position<items.size(); position++) {
LayoutInflater inflater = getLayoutInflater();
View v = inflater.inflate(R.layout.list_basket, null);
final Item i = items.get(position);
if (i != null) {
Item ei = (Item) i;
final TextView title = (TextView) v.findViewById(R.id.title);
if (title != null) title.setText(ei.title);
final TextView articul = (TextView) v.findViewById(R.id.articul);
if (articul != null) articul.setText(ei.articul);
TextView payed = (TextView) v.findViewById(R.id.payed);
if (payed != null) payed.setVisibility(TextView.GONE);
TextView status = (TextView) v.findViewById(R.id.status);
if (status != null) status.setVisibility(TextView.GONE);
Context context = getBaseContext();
ProgressBar p = new ProgressBar(context);
p.setIndeterminate(true);
Drawable d = p.getIndeterminateDrawable();
WebImageView wiv = (WebImageView) v.findViewById(R.id.pic80);
wiv.setImageWithURL(context, ei.pic80, d);
final TextView price = (TextView) v.findViewById(R.id.price);
if (price != null) price.setText(ei.price_valid);
final TextView quant = (TextView) v.findViewById(R.id.quant);
if (quant != null) {
int q = (Integer) all.get(ei.articul);
if (q > 1) {
quant.setText("x "+q+" шт.");
}
}
}
v.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
deletingView = v;
int position = 0; //The order number of the view should be here!
Item item = (Item) items.get(position);
item2delete = item;
position2delete = position;
AlertDialog.Builder builder = new AlertDialog.Builder(getParent());
builder.setMessage(getString(R.string.suredelete))
.setCancelable(false)
.setPositiveButton(getString(R.string.yes),
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
BasketActivity.this.removeItem();
deletingView.setVisibility(View.GONE);
}
})
.setNegativeButton(getString(R.string.no),
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
}
});
l1.addView(v);
}
basketSum = (TextView) findViewById(R.id.basketsum);
basketSum.setText(Html.fromHtml(getString(R.string.basketsum) + ": <b>"
+ basket.getBasketPriceValid() + "</b>"));
}
protected void removeItem() {
basket.remove(item2delete);
Context context = getApplicationContext();
CharSequence text = getText(R.string.item_deleted);
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
basketSum.setText(Html.fromHtml(getString(R.string.basketsum) + ": <b>"
+ basket.getBasketPriceValid() + "</b>"));
items.remove(position2delete);
}
}
My question is how to get view's position at onClick(View v)?

You can use the View's tag;
for (int position=0; position<items.size(); position++) {
v.setTag(position);
}
and in the onClick(View v)
public void onClick(View v) {
int position = 0;
if (v.getTag() instanceof Integer) {
position = (Integer) v.getTag();
}
}

Can you have
v.setTag(items.get(position).getId();
and then in onClick
public void onClick(View v) {
int id= v.getTag();
}
