How to use onBackPressed in an activity that swipes the screen with another activity?

Question

I've a little problem. I've two activities (GalleryActivity and GalleryVideoActivity) and after swiping between them, i would to come back to the first activity (GalleryActivity) pressing just one time on back button because i've to press back button as many times as i swipped. Is it possible? Thanks in advance to everyone!

Answer 1

So if i understand your issue is that you are moving between activities and everytime you move they create new instances so as a solution to suggest is as following, in your manifest file, in activity section add launchMode="SingleInstance", as this would create only one instance of that activity.

• This is an example

  <activity
            android:name=".ui.apppassword.PasswordRestoreActivity"
            android:screenOrientation="portrait"
            android:launchMode="singleInstance"/>

Answer 2

In GalleryVideoActivity override onBackpress method and navigate back to the GalleryActivity by putting simple intent.

Answer 3

Here is what you need to add to GalleryVideoActivity in order to implement onBackPressed as Mike stated:

@Override
public void onBackPressed() {
    Intent toGalleryActivity = new Intent(this, GalleryActivity.class);
    startActivity(toGalleryActivity);
}

This starts GalleryActivity everytime the back button is pressed in GalleryVideoActivity.
