Single choice dialog item selection

Helios · by **Helios** » Wed Feb 25, 2009 4:44 pm

Hi every one. I have implemented a single choice dialog this way:

On my strings.xml I defined the following array and strings:

Syntax: [ Download ] [ Hide ]

Using xml Syntax Highlighting

 
<string name="titulo_pedir_tel">Ingresar número telefónico</string>
 
    <string name="accion_selecionar">Aceptar</string>
 
    <string name="accion_cancelar">Cancelar</string>
 
    <!-- Opciones del menu de envio -->
 
    <string-array name="select_dialog_items">
 
        <item>Enviar vía SMS</item>
 
        <item>Enviar vía email</item>
 
    </string-array>
 
Parsed in 0.002 seconds,  using GeSHi 1.0.8.4

and my single choice dialog is defined as it follows in my main.class

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
Builder builder = new AlertDialog.Builder(this);
 
            builder.setIcon(R.drawable.alert_dialog_icon);
 
            builder.setTitle(R.string.seleccionar_forma_envio);
 
            builder.setSingleChoiceItems(R.array.select_dialog_items, 0, new DialogInterface.OnClickListener() 
 
            {
 
                public void onClick(DialogInterface dialog, int whichButton) 
 
                {
 
                    /* User clicked on a radio button do some stuff */
 
                }
 
            });
 
            builder.setPositiveButton(R.string.accion_selecionar, new DialogInterface.OnClickListener() 
 
            {
 
                public void onClick(DialogInterface dialog, int whichButton) 
 
                {
 
                    /* User clicked Yes so do some stuff */
 
                }
 
            });
 
            builder.setNegativeButton(R.string.accion_cancelar, new DialogInterface.OnClickListener() 
 
            {
 
                public void onClick(DialogInterface dialog, int whichButton) 
 
                {
 
                    /* User clicked No so do some stuff */
 
                }
 
            });
 
           builder.show();

The idea of this is that the user of my app selects a item of the array an base of the selection to realize some action. My problem is that I don't know how to recognize which item of the array the user selected. How can I solve my problem? Thanks in advance.

u have to add code in following method, where "whichButton" corr array index e.g case 0 for index 0; so on.

.setSingleChoiceItems(R.array.select_dialog_items, 0, new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int whichButton){
switch(whichButton){
case 0 :
//code for action after click on first item of array
break;
case 1 :
//code for 2 item
break;
case 2 :

break;
case 3 :

break;
:
:
:

//so on for total num of array item
}
}
})
