Answer 1

final String[] items = {"A", "B", "C"};

final AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Choose me!");
builder.setItems(items, new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int item) {
        if ("A".equals(items[item]) || "B".equals(items[item])) {
            // run whatever...
        }

        if ("C".equals(items[item])) {
            final EditText edit = new EditText(context);

            final Builder builder = new AlertDialog.Builder(context);
            builder.setTitle("Choose a custom option.");
            builder.setView(edit);
            builder.setPositiveButton("Save", new OnClickListener() {

                public void onClick(final DialogInterface dialog, final int which) {
                    String input = edit.getText().toString();
                    // add input to array, or do whatever.

                    dialog.dismiss();
                }
            });
            builder.create().show();
        }

        dialog.dismiss();
    }
});
builder.create().show();

I didn't test it (written straight from my mind), but it should work with a few modifications.

Good luck

TRy this code.. public class Starttracker extends Activity {

String[] Items = {
            "A",
            "B",
            "C",
            "D",

    };

Spinner s1;

@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.start);

s1 = (Spinner) findViewById(R.id.spinner);

final ArrayAdapter<String> adapter  = new ArrayAdapter<String>(
        this,android.R.layout.simple_spinner_item,Items);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
s1.setAdapter(adapter);

} public boolean onItemSelected(AdapterView parent,View v, int position, long id) {

 if (((items[position])=="A")||((items[position])=="B")) {

Chronometer chrono=(Chronometer)findViewById(R.id.chronometer); chrono.start(); } } //.....

            GoodLuck

Answer 3

the answer is following to my question:

{
        int size=tempArray.length;

        for(int i=0;i<size;i++){
            Items.add(tempArray[i]);
}

and

            if(index==3)
            {
                final Dialog dialog=new Dialog(Starttracker.this);
                dialog.setContentView(R.layout.popup);
                dialog.setTitle("Enter The Item");
                dialog.setCanceledOnTouchOutside(true);

                final EditText filename=(EditText)dialog.findViewById(R.id.filename);
                filename.setText("");

                Button d_ok=(Button)dialog.findViewById(R.id.d_ok);
                Button d_cancel=(Button)dialog.findViewById(R.id.d_cancel);


                d_ok.setOnClickListener(new OnClickListener(){

                    public void onClick(View arg0) {
                        // TODO Auto-generated method stub

                        String textHolder = filename.getText().toString();

                        dialog.dismiss();

                        Items.add(textHolder);

                        //  s1.setAdapter(adapter);

                        // notifyDataSetChanged();

                    }
                });
                d_cancel.setOnTouchListener(new OnTouchListener(){
                    public boolean onTouch(View v,MotionEvent me){
                        dialog.dismiss();
                        return false;
                    }
                });
                dialog.show();

                return;
            }

thank a lot to all
