Overview of this book

This book starts with an introduction of Android Studio and why you should use this IDE rather than Eclipse. Moving ahead, it teaches you to build a simple app that requires no backend setup but uses Google Cloud or Parse instead. After that, you will learn how to create an Android app that can send and receive text and images using Google Cloud or Parse as a backend. It explains the concepts of Material design and how to apply them to an Android app. Also, it shows you how to build an app that runs on an Android wear device. Later, it explains how to build an app that takes advantage of the latest Android SDK while still supporting older Android versions. It also demonstrates how the performance of an app can be improved and how memory management tools that come with the Android Studio IDE can help you achieve this. By the end of the book, you will be able to develop high quality apps with a minimum amount of effort using the Android Studio IDE.

Change projections to display KPIs in your app


We can use a different projection and the same observer pattern for displaying some KPIs. Actually that is pretty easy, as we will see in this recipe.

Getting ready

For this recipe, you need to have completed the previous one successfully.

How to do it...

We will continue working on the app from the previous recipe and we will add a new view to display the KPIs:

  1. Open the project you have worked on in the previous recipe.

  2. Add a new layout, fragment_thoughts_kpi.xml:

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android=  
     "http://schemas.android.com/apk/res/android"
      android:orientation="vertical"   
      android:layout_width="match_parent"
      android:gravity="center_horizontal"   
      android:padding="16dp"
      android:layout_height="match_parent">
      <TextView
            android:id="@+id/thoughts_kpi_count"          
            android:textSize="32sp"
            android:layout_margin="16dp"
            android:layout_width="wrap_content"
    ...
