如何销毁上一个活动，但在移动到下一个活动时不包括飞溅和家庭活动？

Question

I have 6 open activities (see the image below).

But what I want to happen is when the user proceeds to orderDetailsActivity it will destroy all the previous activity but not the splashActivity and homeActivity .

So the user can easily move back to homeActivity . And please note that I want to use finish(); when moving back to homeActivity only.

Note: The user can move back and forth from homeActivty , cartActivity and checkoutActivity so destroying those activities right after moving to another one is not possible.

Answer 1

When you move from Checkout Activity to Loading Activity you can simply call finish() to destroy the checkout activity .

In the onBackPressed of Loading Activity you can do like:

Intent intent = new Intent (Loading.this , Home.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.ACITIVTIY_SINGLE_TOP);
startActivity(intent);  
finish();

This would redirect you to the Home Activity (previous instance) and will clear the activities which are on top of the stack. Therefore, what you want is achieved!

Update:

If you want the same thing to happen in the Order Details Activity , you just put the code in onBackPressed of order details :

Intent intent = new Intent (OrderDetails.this , Home.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.ACITIVTIY_SINGLE_TOP);
startActivity(intent);  
finish();

Answer 2

You can use finish()

In your navigation line you add finish()

 Intent it = new Intent (currentActivity.this,MovingActivity.class);
 startActivity(it);
 finish();

and which activity not want to destroy their you add only

 Intent it = new Intent (currentActivity.this,MovingActivity.class);
 startActivity(it);
