startActivities()和startActivity类似，也是界面跳转:

                        Intent[] intents = new Intent[2];

			intents[0] = new Intent(MainActivity.this, Test01.class);

			intents[1] = new Intent(MainActivity.this, Test02.class);

			startActivities(intents);

			//startActivities(intents,null);//bundle

跳转顺序是：由本Activity直接跳转至Test02,返回的时候会经过Test01.
