Question

I have create two radio buttons:

• First, for Bluetooth
• Second, for RS232

But my application shows only one of them.

This is my code :

final RadioButton Bluetooth = new RadioButton(this);
Bluetooth.setId(TEXT_ID);
alertDialogBuilder.setView(Bluetooth);
Bluetooth.setText("Bluetooth");
Bluetooth.setTextSize(20);

final RadioButton RS232 = new RadioButton(this);
RS232.setId(TEXT_ID);
alertDialogBuilder.setView(RS232);
RS232.setText("RS232");
RS232.setTextSize(20);

Use this code to define your alert dialog. Creatre aa xml layout containing two radio buttons and then in java make view and inflathat view in your alert dialog.

                View view2 = View.inflate(MyActivity.this, R.layout.radiobutton, null);

                AlertDialog.Builder builderconversion = new AlertDialog.Builder(MyActivity.this);
                //builder1.setMessage("Radio Message");
                builderconversion.setView(view2);
                builderconversion.setCancelable(true);
                builderconversion.setPositiveButton("CLOSE",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {

                                //Methods and functions
                                dialog.cancel();
                            }
                        });

                AlertDialog alertconversion = builderconversion.create();
                alertconversion.show();
