android - is it possible to create listview inside dialog?

Question

i have created a custom dialog class

public class NewPost extends Dialog
{
// functionality

}

now my requirement is to create listview inside it. i know we can create textboxes,buttons,dropdown list inside it.

but in order to create list view we should inherit our class from listActivity class

what you suggest is it possible or not if yes then how to achieve this using any interface or what?

Answer 1

this implementation doesn't require you to make any xml layouts. it was written as a case statement in "onCreateDialog" override, but you can adapt if for your purposes very easily:

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Select Color Mode");

ListView modeList = new ListView(this);
String[] stringArray = new String[] { "Bright Mode", "Normal Mode" };
ArrayAdapter<String> modeAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, stringArray);
modeList.setAdapter(modeAdapter);

builder.setView(modeList);
final Dialog dialog = builder.create();

dialog.show();

because you are making a dialog with only a ListView, you set the onItemClickListener of the ListView, as there isn't one for the basic dialog class.

modeList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            switch(i) {
                case 0:
                    //do something for first selection
                    break;
                case 1:
                    //do something for second selection
                    break;
            }
            dialog.dismiss();
        }
    });
