You can easily create one on your own. Just create a Button and assign a Layout below. When the Button gets clicked set the View of you Layout to Visible and otherwise to Invisible. Additionaly you can set up and down arrows to the right of your Button.

final Button button = (Button) findViewById(R.id.button);
        final LinearLayout linearLayout= (LinearLayout) findViewById(R.id.linearLayout);
        linearLayout.setVisibility(View.GONE);

        button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                if (linearLayout.getVisibility() == View.VISIBLE) {
                    linearLayout.setVisibility(View.GONE);
                    button.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.expand, 0);

                } else {
                    linearLayout.setVisibility(View.VISIBLE);
                    button.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.collapse, 0);
                }
            }
    });
