How to press physical buttons of android programatically

I want to press volume button programatically. In Java it is possible using the robot class, but in Android there is no robot class.

I am wondering how to achieve this in Android.

I would suggest you to increase/decrease the volume programmatically which would be a tad bit easier, however if you want to use it for some other process then you can check the code below - EDIT - The snippet I gave before doesn't work, but this one does. It uses a runnable so the try catch block is necessary. 

 new Thread(new Runnable() {         
            @Override
            public void run() {
                try {
                    Instrumentation inst = new Instrumentation();
                    //This is for Volume Down, change to 
                    //KEYCODE_VOLUME_UP for Volume Up.
                    inst.sendKeyDownUpSync(KeyEvent.KEYCODE_VOLUME_DOWN);
                }catch(InterruptedException e){}
            }   
        }).start();

how about this 

 private abstract class SimpleButton extends Button {
        public SimpleButton(String text) {
            super(TechDemoLauncher.this);
            setText(text);
            setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    onButtonPressed();
                }
            });
        }

        public abstract void onButtonPressed();
    }

after that you can just implement the onButtonPressed() method like this

private void Example(String string) {
    yourLayout.addView(new SimpleButton(string) {
                @Override
                public void onButtonPressed() {
                    //insert your code
                }
            });
}
