This is my list view acticity:


----------
public class Kitoy extends Activity{

    ListView listView;
    private DBAdapter DBhelper;
    String name,con,add; 


    int howmany;
    String[] recdata;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_kitoy);



            listView = (ListView) findViewById(R.id.listview1);
            DBhelper = new DBAdapter(this);
            DBhelper.open();


         final Cursor getall = DBhelper.fetchAllRows();
            howmany = getall.getCount();

            recdata = new String[howmany];
            int x = 0;

            getall.moveToFirst();
            while (!getall.isAfterLast()) {
                name= getall.getString(getall.getColumnIndex(DBAdapter.NAME)).toString();
            //con = getall.getString(getall.getColumnIndex(DBAdapter.CONTACT)).toString();
            //  add = getall.getString(getall.getColumnIndex(DBAdapter.ADDRESS)).toString();

                recdata[x] = name + con;

                x++;
                getall.moveToNext();
              }


        final ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                      android.R.layout.simple_list_item_1, android.R.id.text1, recdata);
            listView.setAdapter(adapter); 

         listView.setOnItemClickListener(new OnItemClickListener() {


                public void onItemClick(AdapterView<?> parent, View view, int position,
                        long id) {
                        // TODO Auto-generated method stub

                    Intent i = new Intent (view.getContext(), Sapero.class);
                    i.putExtra("item", adapter.getItem(position));

                    //  i.putExtra("con",  Cursor.FIELD_TYPE_STRING(getall.getAllRecords(DBAdapter.CONTACT)));
                    //i.putExtra(DBAdapter.KEY_ROWID, getall.getLong(getall.getColumnIndex(DBAdapter.KEY_ROWID)));

                    startActivity(i);


                };
        });
    }
and this is my second activity to open:


protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sapero);

        call = (Button) findViewById(R.id.button_call);
        sms = (Button) findViewById(R.id.button_sms);
        delete = (Button) findViewById(R.id.delete);

    //  id = getIntent ().getLongExtra(DBAdapter.KEY_ROWID, id);
        //contact =getIntent ().getStringExtra(DBAdapter.CONTACT);

        contact = getIntent ().getStringExtra("con");

        passedView = (TextView)findViewById(R.id.passed);
        passedView.setText("" + contact);

        sms.setOnClickListener(new OnClickListener() {


            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                try{

                String phoneNo = passedView.getText().toString();

            //  smsManager.sendTextMessage(phoneNo, null,null, null, null);
                Intent i = new Intent (Intent.ACTION_VIEW);
                i.putExtra("address", phoneNo);
                i.putExtra("sms_body", "");
                i.setType("vnd.android-dir/mms-sms");
                startActivity(i);
                }
                catch (Exception e){
                    Toast.makeText(getApplicationContext(),
                            "SMS, failed, please try again later!",
                            Toast.LENGTH_LONG).show();
                    e.printStackTrace();

                }
            }
        } );
