![]() ![]() And then lastly, I'll select the 'editText add button' and I will change the layout_margin property of these two components. That means that I've left 5dp space from 4 sides of the layout. So, I'll go to the layout_margin and write 5dp. So, I will select the italic type from the textStyle property. Add, also, I'll delete the text of the edit text and I'll add a hint. So now, I can change the text of the button. So, that means I've divided this layout 5five times and given four pieces to the edit text and one piece to the button. I'll also change the weight of this edit text and I will write 4, and the way it will be just for the one button. Also, I'm going to change the layout_height property of the edit text to 50dp. Why? Because horizontal linear layout, that's going to cover the entire screen. If the height of this layout is match_parent, even if you add items to the ListView component, you won't be able to see the items that you added on the screen. It's very important that you make this change as well my friends. I'll change the layout_height of this horizontal layout to wrap_content. I'll add one text edit and one button under this horizontal LinearLayout. I'll add another LinearLayout under this LinearLayout and this time it's going to be horizontal. Also, I'm going to define the orientation property of this LinearLayout to be vertical. I will write LinearLayout instead of ConstraintLayout. You can continue with a ConstraintLayout if you want. So, I'm going to delete this ConstraintLayout on the XML side. So, when we click on the 'ADD' button, the item will be added to the ListView. Now, if you look at this application, there's an edit text to enter items. So, let's start to design our application. So, I'm going to close my old project and also I'm going to delete this TextView. If you click this icon and select 'Show System UI', you can see how the layout design is going to look on the device. So, you see there's an icon here looks like an eye. So, first let's open the activity_main.xml file. All right, so now, the new project's ready, it's an empty project. So, after I click 'Finish', Android Studio will create a new project for me. So, that means that my app is going to work on 99.8% of all Android devices in the marketplace. Now, I can select where to save this project from here but default is okay for me. So, Android Studio gives a package name automatically. I'll give a name to this project and the name can be To Do List. So, I select Empty Activity, click 'Next'. This project will be for Phones and Tablets. So, first, I want to create a New Project. If you run this application on real device, it's not going to be that slow, promises, truly. The application is working slowly, because it's working on this virtual device. If you click 'NO', it's not going to delete the item from the list. And I do want to point out another feature on the application when you click on an item on the list, it's going to ask you you want to delete this item? If you click 'YES', it will delete the item from the list. So, when I open up the application again, cool, the list is the same. But this time, our application is going to have a new logo. Also, I do want to mention another thing, all the applications that we created were looking into the device with this Android robot icon. I'm going to close the application, open it up again. You want to try it out? All right, let's do it. All the items will get saved to the device's memory. So, the important thing here is when I close the application, the list is not going to be deleted. Also after adding the item, the edit text is cleared. So, for example, I'll just write in here, go to office, I'll click the 'Add' button, and see that the new item is added to the list. After you click the button, boom, it gets added to the list. If you want to add a new item to the list, was right you just write it in here and click the 'ADD' button. We're going to go to Android Studio now and before we start, I will show you what it will be when you're done. So, this is what our project is going to look like. So, congratulations for making it this far. #List file name in listview android studio how to#So, after finishing the project, we're also going to show how to create an APK file, how to publish this project on Google Play. It might seem a little similar, but like I said, practice is, well, practice. One of the most important things on this project, you're going to learn how to save data in the device memory and how to read this data back. Now, you can add something that you want to remember to do right in this list. So, in this video, we're going to do a project and it's going to be a To Do List. So, today we're going to create a new project. ![]()
