Android AutoCompleteTextview With Custom Layout

Hi and welcome to another tutorial from CodingDemos :) Today you will learn how to use Android AutoCompleteTextview that shows completion suggestions automatically while the user is typing. The list of suggestions is displayed in a drop down list from which the user can choose an item to replace the content of the edit box. You will also learn how to create a custom Android AutoComplete by changing the text size, text style, and add a line that separates the items. You will create a custom layout that contains Android textview and view. This textview will show the name of the item while the view is used to show a horizontal line that will separate the items inside AutoCompleteTextview drop down. Here are the steps: 1- Open up Android Studio. 2- Add Android AutoCompleteTextview inside the activity_main.xml file. 3- Open up MainActivity.java file and reference the view AutoCompleteTextview based on its ID. 4- Create an ArrayAdapter that will hold the items of AutoCompleteTextview. This adapter will link to the items that were initialized inside the Strings.xml file. 5- Build and run the app to see the result. 6- Now that you have the basic AutoCompleteTextview showing successfully inside the emulator, next you need to customize the appearance by creating a custom layout called layout_item_autocomplete.xml file. 7- Inside layout_item_autocomplete.xml file, you need to add a textview that will be used to show the name of the item, while you add the other view that will be used as a horizontal line that separates the items. Now change the text size and style of this textview. 8- Next you need to change the ArrayAdapter resource file with the custom file that you've just created together with the textview ID. 9- Build and run the app to see the output. 10- You can change the background color of the AutoCompleteTextview drop down using android:popupBackground. 11- You can set a hint for the AutoCompleteTextview using android:completionHint. 12- You can also change the color of the AutoCompleteTextview selected item using android:dropDownSelector. 13- Build and run the app to see the final result :) Links: Android developer documentation: https://developer.android.com/referen...
