Android Listview item, when I implement setCheck(true) in any checkbox some item changed randomly

this is my first post, and I have a doubt about a listview item management, I have seen some post about recycleView, but I don´t understand yet how to implement it in my problem.
Well, I've got a listView that shows some elements like a shopping car where the user clicks the button autorizarDetalleSolicitud, which opens an alertDialog where an user choices a wished amount of that respective item, so if the amount is bigger than zero, the checkbox changes to state TRUE, but when I test this function, I could see that other checkBoxes are activated (or changes to state TRUE) randomly; i.e. When I input an amount to first item, the state of penultimate checkBox changes to TRUE. Thanks for your attention.
//Button of each listview item
public void autorizarDetalleSolicitud(View v) {
LinearLayout layoutboton = (LinearLayout) v.getParent();
checkBoxelemento = (CheckBox) layoutboton.getChildAt(0);
RelativeLayout relativeLayout = (RelativeLayout) layoutboton.getParent();
TableLayout tableLayout = (TableLayout) relativeLayout.getChildAt(1);
TextView tipoelementotextview = (TextView) tableLayout.findViewById(R.id.tipoelem);
TextView unidadelem = (TextView) tableLayout.findViewById(R.id.unidadelem);
TextView idelem = (TextView) tableLayout.findViewById(R.id.idelem);

cantautorizadatextview = (TextView) tableLayout.findViewById(R.id.cantautorizado);
final String tipoelemento = tipoelementotextview.getText().toString();
cantidadpedida = Double.parseDouble(cantpedida.getText().toString());
cantidadautorizada = Double.parseDouble(cantautorizadatextview.getText().toString());
idelemento = idelem.getText().toString();
// configura el alert dialog

builder.setMessage(unidadelem.getText() + " a autorizar:");

String[] nums = new String[100];
for (int i = 0; i < nums.length; i++) {

}

SOLUTION!
To solve my problem, I based on this answer recording an array with positions of the checkboxes verifying if they were checked, I mean, this a boolean array, and each checkbox has a status TRUE or FALSE. Thanks to #AnshulTyagi
public class ElementoAdapter extends BaseAdapter {
private ArrayList<Boolean> status = new ArrayList<Boolean>();
private static LayoutInflater inflater = null;
private ArrayList<HashMap<String, String>> data;
Activity activity;
CompoundButton.OnCheckedChangeListener miCheckedListener = new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton checkBoxView,boolean isChecked){
int posicioncheck = (Integer)checkBoxView.getTag();
if (checkBoxView.isChecked()) {
status.set(posicioncheck,true);
} else {
status.set(posicioncheck,false);
}
}
};
public ElementoAdapter(Activity activity, ArrayList<HashMap<String, String>> data){
this.activity = activity;
this.data = data;
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
for (int i = 0; i < data.size(); i++) {
status.add(false);
}
}

Deleting listview item from database

I am deleting the title 2 list item item
But the last title gets deleted that is the title 8 gets deleted
When I then go back to the previous screen and reopen the list. The correct that is the 2nd item title 2 had been deleted.

Android getting unchecked checkbox in checklist after search in edittext

I have checklist with search functionality(used edittext). When I use it to search it shows filtered items so that I can make the selection that I want, it works properly. However, the checked items become unchecked when the search functionality reloads the list. I want the items selected before the search to remain selected. How can I fix this?

ListView recycles the views every time its associated edit text's value is changed. That's why the Check-boxes does not retain their states.
To accomplish your task:
Store the checked items in an array.
When you click any checkbox in the listview, change the value of that particular item in the array.
Inside your getView method, check or uncheck the Check-boxes by reading the values from the array.
That way your checkboxes will retain their states. I hope this is clear.

Android dynamic Multicolumn Listview

I have a multicolumn List view like the one shown in the image, i used custom adapters to populate this custom list.so the question is how to get data on click of submit button means when i click submit button i should get data like name, price and quantity of only checked checkbox....Thanx in advance.

i'm able to view data in list view, bt the problem is i m unable to save data on click of submit button... so plz help me out, with a sample code, bcz m new to android..
the following is my code..
public class Menu extends Activity {

Android - How to remove list item?

I have got a main extending adapter which adds rows when user clicks on a button. In the adapter, I got a remove item button and a checkbox. How do I remove the item from the list?
public class main extends Activity{
ArrayList<String> noteList = new ArrayList<String>();
FancyAdapter aa = null;
Button calculate;
EditText result;
String total;
String name;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Spinner spinner = (Spinner)findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this, R.array.spinner_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
ListView myListView = (ListView)findViewById(R.id.noteList);
aa = new FancyAdapter();
final EditText price = (EditText)findViewById(R.id.price);
final EditText name1 = (EditText)findViewById(R.id.name);
myListView.setAdapter(aa);
myListView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1,
int position, long arg3) {
}
});
Button btnSimple = (Button)findViewById(R.id.btnSimple);
btnSimple.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
try
{
double totalPrice = Double.parseDouble(price.getText().toString());
int position = spinner.getSelectedItemPosition();
name = name1.getText().toString();
if(position == 0)
{
totalPrice = totalPrice * 1.07;
total = String.valueOf(totalPrice);
System.out.println(total);
}
else
{
totalPrice = (totalPrice * 1.1)*1.07;
total = String.valueOf(totalPrice);
System.out.println(total);
}
String wholeString = name + ":$" +total;
noteList.add(0, wholeString);
System.out.println(total);
name1.setText("");
price.setText("");
aa.notifyDataSetChanged();
}
catch (Exception e)
{
}
}
});
}
class FancyAdapter extends ArrayAdapter<String>
{
Button calculate;
EditText price;
EditText result;
FancyAdapter()
{
super(main.this, android.R.layout.simple_list_item_1, noteList);
}
public View getView(int position, View convertView, ViewGroup parent)
{
View row = convertView;
if(row == null)
{
LayoutInflater inflater = getLayoutInflater();
row = inflater.inflate(R.layout.custom_list_item, null);
}
StringTokenizer tokens = new StringTokenizer(noteList.get(position), ":");
String first = tokens.nextToken();
String second = tokens.nextToken();
row.getTag();
((TextView)row.findViewById(R.id.nametv)).setText(first);
((EditText)row.findViewById(R.id.result)).setText(second);
Button deleteButton = (Button) row.findViewById(R.id.button);
deleteButton.setTag(position);
deleteButton.setOnClickListener(
new Button.OnClickListener() {
public void onClick(View v) {
}
}
);
return (row);
}
}
}

remove list item, and invoke notifyDataSetChanged();
public View getView(int position, View convertView, ViewGroup parent)
{
View row = convertView;
if(row == null)
{
LayoutInflater inflater = getLayoutInflater();
row = inflater.inflate(R.layout.custom_list_item, null);
}
StringTokenizer tokens = new StringTokenizer(noteList.get(position), ":");
String first = tokens.nextToken();
String second = tokens.nextToken();
row.getTag();
((TextView)row.findViewById(R.id.nametv)).setText(first);
((EditText)row.findViewById(R.id.result)).setText(second);
Button deleteButton = (Button) row.findViewById(R.id.button);
deleteButton.setTag(position);
deleteButton.setOnClickListener(
new Button.OnClickListener() {
public void onClick(View v) {
noteList.remove(position);
notifyDataSetChanged();
}
}
);
return (row);
}

Remove the item from the arraylist using
noteList.remove(itemIndex);
and then call
aa.notifyDataSetChanged();
