title: How to show a floating message with a help message to the user
body: <p>I modified my app, i.e changed the style of the app from an expandable lisview to show it's content to a viewpager with a pagetitlestrip. Now my app is much more cute but uninstalls have increased a lot since my new update has been released.</p>
  
  <p>I'm pretty sure that users are uninstalling my app because they don't know that they must do a swipe movement to the left to see the next content of the app. </p>
  
  <p>So I think that I need to add some help for the users. I thought about a floating imageview of an arrow to the right with a message showing the text "move to right to see more content" and a close button.</p>
  
  <p>Which is the best strategy to achieve this? Whould be to use some xml tricks? or it should be done by java code? Any sample codes whould be great.</p>
  
  <p>This is my xml layout:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;android.support.v4.widget.DrawerLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:id="@+id/drawer_layout"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
      &lt;!-- The main content view --&gt;
      &lt;RelativeLayout
          android:id="@+id/main_layout"
          android:layout_width="match_parent"
          android:layout_height="match_parent"&gt;
          &lt;android.support.v4.view.ViewPager
              xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/pager"
              android:layout_width="match_parent"
              android:layout_height="match_parent"&gt;
              &lt;android.support.v4.view.PagerTitleStrip
                  android:id="@+id/pager_title_strip"
                  android:layout_width="match_parent"
                  android:layout_height="wrap_content"
                  android:layout_gravity="top"
                  android:paddingTop="4dp"
                  android:paddingBottom="4dp"
                  style="@style/CustomPagerTitleStrip"/&gt;
          &lt;/android.support.v4.view.ViewPager&gt;
      &lt;/RelativeLayout&gt;
      &lt;!-- The navigation drawer --&gt;
      &lt;android.support.design.widget.NavigationView
          android:id="@+id/navigation_view"
          android:layout_width="wrap_content"
          android:layout_height="match_parent"
          android:layout_gravity="start"
          android:fitsSystemWindows="true"
          app:headerLayout="@layout/drawer_header"
          app:menu="@menu/drawer_menu"
          style="@style/NavigationDrawerStyle"/&gt;
  &lt;/android.support.v4.widget.DrawerLayout&gt;
  </code></pre>
