How to go back between several Android activities

  • 772

I have a problem I hope someone can help me.

I have several activities

MainActivity, Activity1, Activity2, Activity3

MainActivity let's say it's a list and activities 1 to 3 are forms, in activity3 when a save ends I need to return to the MainActivity, but if I use finish I only return to the previous one, I don't want to use startActivity because when they hit the button from the phone "return" would return to Activity3.

Thanks.

    To achieve what you want you first have to indicate that your main activity will have only one instance using the attribute android:launchModeon the manifest.xml.

    For example:

    <activity
   android:name="..."
   android:launchMode="singleTask"
   />

    So when you need to return to your activity you call it using the method startActivity:

    Intent intent = new Intent(context, MyActivity.class );
intent.setFlags( Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity( intent );

    FLAG_ACTIVITY_CLEAR_TOPwhat it does is remove the stack of active activities.
