推荐答案

您需要先使用 startActivityintent 您当前的 context 到另一个活动>.之后，您可以从重定向的位置完成您当前的activity.

You need to intent your current context to another activity first with startActivity. After that you can finish your current activity from where you redirect.

 Intent intent = new Intent(this, FirstActivity.class);// New activity
 intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 startActivity(intent);
 finish(); // Call once you redirect to another activity

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP) - 清除活动堆栈.如果您不想清除活动堆栈.那么请不要使用那个标志.

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP) - Clears the activity stack. If you don't want to clear the activity stack. PLease don't use that flag then.
