Snackbar with CoordinatorLayout disable dismiss

Question

I am using the support

• FloatingActionButton
• Snackbar
• CoordinatorLayout

I need the CoordinatorLayout so that if SnackBar is shown the FloatingActionButton moves up to make room for the Snackbar. For better understanding check this video.

I am using SnackBar for double-back to exit the application, but the SnackBar can be dismissed.

Is there a way to disable the dismiss on the SnackBar?

Snackbar snackbar = Snackbar.make(view, R.string.press_back_again_to_exit, Snackbar.LENGTH_SHORT);
snackbar.setAction(R.string.ok, new View.OnClickListener() {
    @Override
    public void onClick(View v)
    {

    }
});
snackbar.setActionTextColor(getResources().getColor(R.color.white));

View view = snackbar.getView();
view.setBackgroundColor(getResources().getColor(R.color.orange_warning));

snackbar.show();

        app:elevation="6dp"
        app:fabSize="normal"/>

</android.support.design.widget.CoordinatorLayout>

P.S.

I am aware of this GitHub library, that has this functionality, but is there a 'native' way to do it?

Answer 1

Snackbar now has actual support disabling swipe to dismiss using the setBehavior method. The great thing here is that before you would always lose some behaviors which are now preserved. You'll also want to use Snackbar.LENGTH_INDEFINITE

Note that the package moved so you have to import the "new" Snackbar in the snackbar package.

Snackbar.make(view, stringId, Snackbar.LENGTH_INDEFINITE)
    .setBehavior(new NoSwipeBehavior())
    .show();

class NoSwipeBehavior extends BaseTransientBottomBar.Behavior {

    @Override
    public boolean canSwipeDismissView(View child) {
      return false;
    }
}
