In my opinion, jumping to a new activity to show your menu is a kind of wasting time and life.

So,

I think, we need a hover view, to show menu, to show messages.

  in build.gradle defaultConfig, here is a sample

dependencies {
	compile "com.android.support:support-v4:20.+"
	compile 'com.nineoldandroids:library:2.4.0'
	compile 'com.daimajia.easing:library:1.0.0@aar'

1. Create an original view, and make sure it was wrapped by BlurLayout

   for example:

   	<com.daimajia.androidviewhover.BlurLayout
   			android:id="@+id/sample"
               android:layout_width="wrap_content"
               android:layout_height="wrap_content">
               <ImageView
                   android:layout_centerInParent="true"
                   android:scaleType="fitXY"
                   android:src="@drawable/kid"
                   android:layout_width="match_parent"/>
   	</com.daimajia.androidviewhover.BlurLayout>

   Note: BlurLayout is entended from RelativeLayout. You can use the RelativeLayout rules to layout your view.

2. Create a hover view, there is no rules to obey. Just please remember that this view will be stretched as large as the original view you have created.

3. Bind a hover view to BlurLayout

   	BlurLayout sampleLayout = (BlurLayout)findViewById(R.id.sample);
   	View hover = LayoutInflater.from(mContext).inflate(R.layout.hover, null);
   	sampleLayout.setHoverView(hover);

   and don't forget that you can add various animations just in one line code. For example:

   	//View (R.id.heart) appear animation.
   	sampleLayout.addChildAppearAnimator(hover, R.id.heart, Techniques.FlipInX);
   	//View (R.id.heart) disappear animation.
   	sampleLayout.addChildDisappearAnimator(hover, R.id.heart, Techniques.FlipOutX);

You can view the samples in my preset examples.

This project provides a lot of animations you can choose. Animations are from my another open-source project AndroidViewAnimations. And you can aslo using easing funcitons to make your animations more real. Please enjoy it.
