YouвЂ™ve replaced the hardcoded font size of 24sp with the uniform AutoSizeTextType, but this time programmatically. TextViewCompat.AUTO_SIZE_TEXT_TYPE_UNIFORM) Replace the call to setTextSize(TypedValue.COMPLEX_UNIT_SP, 24f) with the following: To fix this, open JokeDetailActivity.kt and find the buildTextView() method. However, if you try to add a TextView in the Detail Screen, it wonвЂ™t autosize when you pinch the view because itвЂ™s added at runtime.

YouвЂ™ll notice that the TextViews in the List Screen and the Detail Screen now autosize correctly. Open activity_detail.xml and change the joke description TextView with the id the same way to be the following:Д«uild and run the application. Now, following the same pattern, change the joke TextView with id to add app:autoSizeTextType='uniform'. To get rid of it, change from TextView to 7.widget.AppCompatTextView. Note: If you are using a minSdk lower than 26 in your own project when using this, you may see a warning. Notice that you have added app:autoSizeTextType='uniform' to enable autosizing. Open joke_item.xml, which the List Screen uses, and change the emoji TextView with id to include this attribute. Otherwise, the default is none, which disables this autosizing feature. If you want to enable autosizing, you need to set the app:autoSizeTextType property to uniform in the xml. There are three options that you need to consider when configuring the Autosize properties: AutoSizeTextType, Granularity and Preset Sizes.

activity_detail.xml: Is the layout for the Detail Screen.Д¬onfiguring TextView Autosizing Properties.

joke_item.xml: Is the layout for each of the list items in the List Screen.

JokeDetailActivity.kt: Shows a single joke and lets you add additional text, customize the background and share.

To fix these problems, youвЂ™ll need to modify the code to autosize the TextViews according to their width and height. Also, resizing the text in the Detail Screen doesnвЂ™t adjust the font size to the frame of the TextView. You may have noticed that much of the text in the List Screen is sometimes cut off.

When you have finished customizing the page, you can share it with your friends. You can also move and pinch the TextViews. You can add more text and customize the background.
