Create a mobile-optimized app that uses responsive designs
In this exercise, we create a mobile-optimized one-screen app based on our Contoso Coffee Machines data. The purpose of this exercise is to give you experience building an app with auto-layout containers, and to show you first-hand how responsive apps behave. We create a brand-new app, so head to the Power Apps home page and follow these steps.
Download the Excel spreadsheet CoffeeMachineData.xlsx. Select the link and then the Download raw file button to download the file. Once it downloads, continue with the next step.
Select Create > Blank app > Tablet. Provide your app with a name and press Create.
You can refer to the diagram below for assistance with the next few steps, numbered according to the steps. In the command bar, select the Settings button. (You might need to select App in the Tree view panel to show it.)
In the Settings popup panel, select the Display tab, then scroll down and turn Off the Scale to fit option (this action automatically switches the Lock aspect ratio to Off).
Close the Settings popup.
Create a New screen with a Sidebar layout for your app. Name it "Catalog Screen".
Create a New screen from the Templates > Success. Name it "Success Screen".
Delete Screen1.
Next select the Add data button from the command bar. Then find/select OneDrive for Business.
Under the Choose an Excel file panel on the right side of your screen, select your CoffeeMachineData.xlsx file, then select the CoffeeMachines table. Connect the table by selecting Connect at the bottom of the panel.
Select the horizontal container on the left side of your screen, called SidebarContainer1. Refer to the image below for the next several steps.
Select the plus (+) icon in the container and insert a Vertical gallery into SidebarContainer1 and select CoffeeMachines as the data source. Set the Fill property to Color.LightSteelBlue.
Next we'll insert a form in the Catalog Screen. Select MainContainer1 which is on the right side of your app canvas. Select the plus (+) icon (or the Insert button from the command bar) to insert an Edit form. In the Properties panel on the right side of the screen, select CoffeeMachines as the Data source.
Still in the Properties panel, select the Edit fields option under the Data source.
In the Fields panel, select Add field and add all the fields by checking the box next to each field name in the Choose a field popup. Then select the Add button at the bottom.
Close the Fields panel.
While the Form1 is still selected, in the Property dropdown menu at the top left of the screen, select the Item property, and in the formula (fx) field input: Gallery1.Selected
Finally, still on your form, set the Fill property to: Color.LightSteelBlue
Next, we add to our header container. Select the HeaderContainer control and use the plus (+) icon to insert a Text label control, and adjust the properties in the dropdown as follows:
Text: "Contoso Coffee Catalog"
Size: change from 13 to 20
Height: change from 40 to Parent.Height
Width: change from 150 to 200
Using the Align button in the command bar (to the left of the Color button; alternatively, you can look for the Text alignment selection in the Properties panel on the right), change the Align from Align left to Justify.
Next, insert an Image control to HeaderContainer1, and adjust the properties as follows:
Image: User().Image
Height: Parent.Height
Let's create a connection icon by inserting a Globe icon into HeaderContainer1. Adjust the properties as follows:
Height: 20
Width: 20
Color: If(Connection.Connected, Color.Green, Color.LightSteelBlue)
Next, we right-justify our HeaderContainer items. To do this, look in the Properties panel on the right and look for the Justify (horizontal) option. The third option is End. Go ahead and select it.
Finally, let's add some background color to our header container. Adjust the Fill property to: Color.LightSteelBlue
Select MainContainer1, where your form resides. Insert a Button control with the following properties:
Text: "Save"
Width: Parent.Width
OnSelect: SubmitForm(Form1)
Select the form inside of MainContainer1, and adjust the OnSuccess property to: Navigate(Screen3)
From your Tree view panel, select the Success Screen.
Select the Check icon (iconCheck1), and update the OnSelect property to:
Back()Place the app in preview mode. Adjust the display to the iPhone 12 by selecting the Phone dropdown. Did you notice how your display changed the controls? Try some different tablets and phones switching orientation to see how the screen changes.
Our simple, responsive app is now usable on any platform. Way to go!
