如何使Button像Spinner一样

Question

I want a Button pull up a menu like a Spinner but it doesn't need to store data like the prompt in a Spinner.

A Spinner looks like this:

Spinner spinner = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.social_list, android.R.layout.simple_gallery_item);//select_dialog_multichoice);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());

I need to work same thing as a Button... Thanks

Answer 1

i think you should put spinner.performClick(); on button click method

Answer 2

You can make use of ContextMenu . Here is a link about Context Menu Demo.

But little modifications are required. Inside the button click event, you have to open the ContextMenu.

Answer 3

use Resources res = getResources();

final String[] items = res.getStringArray(R.array.social_list);
//final CharSequence[] items = {"Red", "Green", "Blue"};

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Pick a color");
    builder.setItems(items, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int item) {
            Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show();
        }
    });
    AlertDialog alert = builder.create();
