java - Android Dialog如何从自定义适配器Dialog适配器获取文本

Question

this is my code in my adapter.. the int which indicates the id of the item, but how can i get the text value of the item? i want to display it to my button after selecting the item from the dialog..  

builder.setSingleChoiceItems(adapter,-1, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        switch(which) {
            case 0:
        }
        dialog.dismiss();   
    }
});

有办法使用这个代码吗？但根据我的研究， onItemSelected 只能实现到 listview 和 spinner ..但就我而言，如何在自定义警报对话框适配器中使用它？

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
    // On selecting a spinner item
    String label = parent.getItemAtPosition(position).toString();

    // Showing selected spinner item
    Toast.makeText(parent.getContext(), "You selected: " + label, Toast.LENGTH_LONG).show();
}

I solve this by adding this to my code.

 builder.setSingleChoiceItems(adapter,-1, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {  
            String itemName=adapter.getItem(which);
            button.setText(itemName);   
            dialog.dismiss();   
        }
    });

my adapter variable is declared by ArrayAdapter<String> adapter = new ArrayAdapter<String> by adding

String itemName=adapter.getItem(which);
button.setText(itemName); 

The which variable corresponds to the ID position of the item within the dialog and using adapter.getItem() it can call the string value of the item so i display it to my button.
