How can you adjust Android SnackBar to a specific position on screen

Follwing the new android snackbar, i'm trying to set it to be positioned on a specific y coordinate. Its seems to be not even a possible.

I've tried with getting the parent of the snackbar's view, but, there's nothing to be done to the parent for it to set the position of it.

mSnackBar.getView().getParent();

When digging into the actual class, there's an instance of mView, and mParent which is private, and can't be reached anyhow.

Solution

  • It is possible to set the location that the Snackbar is displayed by positioning a android.support.design.widget.CoordinatorLayout within your existing Activity layout.

    For example, say your existing layout is a RelativeLayout you could add a CoordinatorLayout as follows:

    <android.support.design.widget.CoordinatorLayout
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:id="@+id/myCoordinatorLayout"
    android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true">
</android.support.design.widget.CoordinatorLayout>

    Then, make sure you pass the CoordinatorLayout as the first argument of the Snackbar.make() command.

    final View viewPos = findViewById(R.id.myCoordinatorLayout);    
Snackbar.make(viewPos, R.string.snackbar_text, Snackbar.LENGTH_LONG)
                            .setAction(R.string.snackbar_action_undo, showListener)
                            .show();

    This will result in the Snackbar being shown at the bottom of the CoordinatorLayout provided to the make() function.

    If you pass a View that is not a CoordinatorLayout the Snackbar will walk up the tree until it finds a CoordinatorLayout or the root of the layout.
