How to switch among items in AlertDialog?

I'm creating an AlertDialog with setting array (R.array.select_dialog_items) of items to it:

<string-array name="select_dialog_items">
    <item>Start</item>
    <item>Stop</item>
    <item>Delete</item>
</string-array>

I don't know how to switch among these items in onClick() method, can you advice?

public void init() {
        builder = new AlertDialog.Builder(mContext);
        builder.setTitle("Task");
        builder.setItems(R.array.select_dialog_items, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dial开发者_C百科og, int item) {
                switch (item){
                case : // How to iterate here?
                }
            }
        });
        alert = builder.create();
    }

int item of the onClick method represents the position of the item clicked in the alertDialog (as mentioned in the API here. Therefore:

public void init() {         
builder = new AlertDialog.Builder(mContext);         
builder.setTitle("Task");         
builder.setItems(R.array.select_dialog_items, new DialogInterface.OnClickListener() {             
public void onClick(DialogInterface dialog, int item) {                 
switch (item){                 
        case 0: // Start item
           some code...
           break;

        case 1: // Stop item
           some code...
           break;

        case 2: // Delete item
           some code...
           break;
}            
 }         
});        
 alert = builder.create();     } 

Give that a try.
