推荐答案

FragmentActivity也是活动。非常简单，我们可以使用intent从活动中打开FragmentActivity。



考虑例子： -



A =活动

B = FragmentActivity



意图i =新意图（Activity.this，FragmentActivity.class）;

startActivity（i）;

FragmentActivity is also activity. So very simple we can use intent to open FragmentActivity from activity.

Consider Example:-

A = Activity
B = FragmentActivity

Intent i = new Intent(Activity.this,FragmentActivity.class);
startActivity(i);
