使用导航抽屉和后退按钮在活动之间正确导航？

Question

I have the following situation:

One Main ListActivity . The list consists of POJO objects, each item is a different POJO.

Each POJO contains different groups. For each group I made different Activity .

Lets say POJO1 contains groups A , B and C , when pressed, ActivityA will be opened and the navigation between the rest activities ActivityB and ActivityC is done using NavigationDrawer .

All group activities implement a custom class MyNavigationDrawerClass which is the core of the Navigation Drawer in my app.

Each ActivityA , B , C , etc, has a SettingsActivity which is strictly individual and depends on from where it has been started.

Now the question is: How to navigate from any A , B , C , etc, activity to the Main ListActivity every time the BackButton is pressed?

I will provide an example:

1. App is started - Main List Activity is showed;
2. Item is pressed and ActivityA with NavigationDrawer is started;
3. The NavigationDrawer is opened and ActivityC is opened;
4. When BackButton is pressed, the user is navigated back to ActivityA , but my desire is to navigate the user to the Main List Activity

What I tried:

1. To put android:noHistory="true" for every ActivityA , ActivityB and ActivityC in the AndroidManifest . That did not work because when I open the SettingsActivity for example from ActivityA and return, the user in navigated to the Main List Activity , and not to the ActivityA - it's confusing and misleading.
2. To override onBackPressed in MyNavigationDrawerClass and start the Main List Activity using Intent . That did not work either because there are still previous activities in the stack and when the BackButton is pressed from Main List Activity , the user is navigated to them.

I hope I explained the situation clearly.

Any help will be appreciated.

You can override the public void onBackPressed(){...} for redirect the user where you want like this :

public void onBackPressed()
{
    Intent intent = new Intent(this.getApplicationContext(), MainListActivity.class);
    startActivity(intent);    
}
