How to move a view above Snackbar just like FloatingButton

Question

I got a linear layout that I want to move up when a Snackbar appears.

I saw many examples how to do this with FloatingButton, but what about a regular view?

I'm going to elaborate on the approved answer because I think there's a slightly simpler implementation than that article provides.

I wasn't able to find a built-in behavior that handles a generic moving of views, but this one is a good general purpose option (from http://alisonhuang-blog.logdown.com/posts/290009-design-support-library-coordinator-layout-and-behavior linked in another comment):

import android.content.Context; import android.support.annotation.Keep; import android.support.design.widget.CoordinatorLayout; import android.support.design.widget.Snackbar; import android.support.v4.view.ViewCompat; import android.util.AttributeSet; import android.view.View;  @Keep public class MoveUpwardBehavior extends CoordinatorLayout.Behavior<View> {      public MoveUpwardBehavior() {         super();     }      public MoveUpwardBehavior(Context context, AttributeSet attrs) {         super(context, attrs);     }      @Override     public boolean layoutDependsOn(CoordinatorLayout parent, View child, View dependency) {         return dependency instanceof Snackbar.SnackbarLayout;     }      @Override     public boolean onDependentViewChanged(CoordinatorLayout parent, View child, View dependency) {         float translationY = Math.min(0, ViewCompat.getTranslationY(dependency) - dependency.getHeight());         ViewCompat.setTranslationY(child, translationY);         return true;     }      //you need this when you swipe the snackbar(thanx to ubuntudroid's comment)     @Override     public void onDependentViewRemoved(CoordinatorLayout parent, View child, View dependency) {         ViewCompat.animate(child).translationY(0).start();     } } 

then, in your layout file add a layout_behavior as below:

<LinearLayout     android:id="@+id/main_content"     android:orientation="vertical"     app:layout_behavior="com.example.MoveUpwardBehavior"/> 

where the layout_behavior is the full path to your custom behavior. There's no need to subclass LinearLayout unless you have a specific need to have a default behavior, which seems uncommon.
