Answer 1

You can add images to layout with tabs:

and add listener in your tab activity:

getTabHost().setOnTabChangedListener(new OnTabChangeListener() {
        public void onTabChanged(String tabId) {
            if (tabId.equels("left")){
                findViewById(R.id.down_arrow_left).setVisibility(View.VISIBLE);
                findViewById(R.id.down_arrow_right).setVisibility(View.INVISIBLE);
            } else if (tabId.equels("right")){
                findViewById(R.id.down_arrow_left).setVisibility(View.INVISIBLE);
                findViewById(R.id.down_arrow_right).setVisibility(View.VISIBLE);
            }
        }
    });
