Activity Navigation Logic

Question

I have 3 Activities...the first Activity have a button that start third Activity. The problem is: When I am in 3 - rd activity press "back" button its navigate me back to 1 - st Activity, but i need to 2 - nd one. My stack of Activities always should look like : 1. first Activity 2. second Activity 3. third Activity

How to do that ? Thanks...

Answer 1

If the 2nd activity is not on the stack - which it sounds like it isnt, because you went from 1st -> 3rd - which means that in your 3rd activity you will have to implement onKeyDown and capture the BACK key, and then start a new Intent with the 2nd activity.

Answer 2

You can intercept the back button from Activity 3:

@Override
public void onBackPressed() {
    // start Activity 2
    return;
}

See this article for more details.

Note: this only works with Android 2.0 or later.
