Answer 1

Change your showSelectedNumber method as :

public void showSelectedNumber(int type, String number) {
    // Toast.makeText(this, type + ": " + number, Toast.LENGTH_LONG).show(); 
    // txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo2);
    if(txtPhoneNo != null && txtPhoneNo.getText().toString().length()==0)
         txtPhoneNo.setText(number);
    else
         if(txtPhoneNo != null) txtPhoneNo.append(","+number);

}

Answer 2

You need to add the selected number to a string before you call settext() on textview.

something like this :

String str ="number1"+"number2"+....+"numberN"
txtphonenO.setText(str);
