Android - Create a settings object similar to volume control

Question

As the title says, I was wondering if there is a way to add a way to create input in my Android application, by providing the user with a bar similar to the one used by Android system for adjusting the sound volume. A specific variable would change its value, according to the position of a "button" on the bar (sorry for my English). Any advice on that?

Answer 1

A SeekBar is what you are looking for.

Here is the design spec: https://www.google.com/design/spec/components/sliders.html#

Here is the reference page: http://developer.android.com/reference/android/widget/SeekBar.html

If you want to set the value of the position of the SeekBar, simply do:

seekBar.setProgress(position);

where position is where you want the SeekBar to be.

Getting the position of the SeekBar is a bit more involved. Firstly you must set a setOnSeekBarChangeListener and grab the SeekBar value from within the onProgressChanged method. This is a StackOverflow question that answers this well: get android seekbar value and display it on screen
