Android: create a popup that has multiple selection options

You can create a String array with the options you want to show there and then pass the array to an AlertDialog.Builder with the method setItems(CharSequence[], DialogInterface.OnClickListener).

An example:

String[] colors = {"red", "green", "blue", "black"};

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Pick a color");
builder.setItems(colors, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // the user clicked on colors[which]
    }
});
builder.show();

The output (on Android 4.0.3):

(Background map not included. ;))

Try this :

public void onClick(View v) {

    final String[] fonts = {
        "Small", "Medium", "Large", "Huge"
    };

    AlertDialog.Builder builder = new AlertDialog.Builder(TopicDetails.this);
    builder.setTitle("Select a text size");
    builder.setItems(fonts, new DialogInterface.OnClickListener() {@
        Override
        public void onClick(DialogInterface dialog, int which) {
            if ("Small".equals(fonts[which])) {
                Toast.makeText(TopicDetails.this, "you nailed it", Toast.LENGTH_SHORT).show();
            } else if ("Medium".equals(fonts[which])) {
                Toast.makeText(TopicDetails.this, "you cracked it", Toast.LENGTH_SHORT).show();
            } else if ("Large".equals(fonts[which])) {
                Toast.makeText(TopicDetails.this, "you hacked it", Toast.LENGTH_SHORT).show();
            } else if ("Huge".equals(fonts[which])) {
                Toast.makeText(TopicDetails.this, "you digged it", Toast.LENGTH_SHORT).show();
            }
            // the user clicked on colors[which]

        }
    });
    builder.show();
}

The pop ups are nothing but AlertDialog.So you just need to create AlertDialog, then inflate your desired view using LayoutInflater and set the inflated view using setView() method of AlertDialog
