If we are using code to create a button on the screen, we would do something similar to this:. The equivalent interface in XML would be created and stored in the layout sub-folder of the Resources folder and reads as follows:. Once we have created the interface in XML, we have to indicate to the activity which layout file is to be used. For example, say we named our layout file Main.

A refined design

Regardless of whether the layout was created in code or through XML files, we are able to access the various controls similarly:. In order to access the control at runtime, we make use of the FindViewById method on the activity or a view use the View property of a fragment :. Separating the UI from the code allows us to easily make changes for updates as well as to support different screen configurations. The benefit of this is that it allows us to modify the UI without updating the code.

And part of this is the fact that the Android system can switch the entire layout at runtime. Different layouts for different screen configurations can be selected simply by changing the suffix of the layout folder name. Fragments can be used in addition to layouts to create advanced interfaces consisting of self-contained, reusable regions. For example, if we want our Main layout to have the LinearLayout method to be vertical in portrait orientation and horizontal in landscape orientation, all we have to do is create two layout files with the same name in different folders as follows:.

There are many uses for the suffixes, and there are many different suffixes. Each of the resource subfolders can have suffixes, including values, layout, menu, and drawable. Each of the folders can have combinations of the suffixes for language or culture, screen orientation, screen density, screen size, and platform version. The Android layout structure usually follows the structure of the type, with the element name matching the type name and property names matching the attribute names.

Although we can nest one or more layouts within another layout, we should strive to keep our layout hierarchy as shallow as possible. The layout will be drawn faster if it has fewer nested layouts. One of the most important attributes in layouts is the id attribute. This attribute is used to uniquely identify a view within a tree.

An ID need not be unique throughout the entire tree, but it should be unique within the part of the tree that is being searched. The ID need not be unique, but it's best to be completely unique when possible so that the specific view can be found in the hierarchy. Layout files are an easy way to create the UI separate from the code, and in the same way, resource files can be used to separate the localizable text from the layout. This is achieved by placing the strings into a resource file and then, referencing each the string from the layout.

Say we have a button that has some text:. Using this pattern, we are able to not only extract strings but any value for any attribute, including layout information. An example would be to extract an element's padding and use a larger padding for larger screens. These types of resources are placed in the values folder with a suffix, such as -large for large screens. Android provides the user with the ability to display a special type of menu that contains a set of items that pertains to the entire app, instead of the current activity.

Adding an options menu to our app is very simple, and only two things are required: a menu structure and code to connect the menu with the activity. In order to use a menu layout file, a resource file needs to be added:. First, we create a new XML file with the name of the menu, for example Options. Then, we create the menu structure in this file, for example, create three menu items: refresh, settings, and about. Once we have the structure, we override the OnCreateOptionsMenu method and inflate the resource:.

If we want to respond to items being selected in that menu, all we need to do is override the OnOptionsItemSelected method:. Menus, especially the options menu, are both simple and important to Android apps. The Options menu contains items that are relevant to the current activity. They are important, but they are often not commonly used and so don't have a dedicated space in the layout. As with traditional layout files, using resource files for menus allows greater flexibility for the many screen configurations as well as for simplifying customizations to menus. Each menu item contains a unique ID, which allows the system to recognize the item when the user selects it, and a title, which is used to present the item to the user.

There are also additional properties, the most commonly used of these being the icon. When using action bars, this icon is used to display an image alongside, or in place of, the title. The MenuInflater instance creates the menu structure from the resource file and inflates it into the IMenu instance.

All the menu items in the resource will be added as children to the menu. The OnCreateOptionsMenu method should return true if the menu is to be displayed. Returning false will result in the menu not being displayed. When we handle the menu item selections, the menu item that was selected is passed into the OnOptionsItemSelected method.

Preface With a rapid increase in the use of mobile devices everywhere, developing for Android takes advantage of this trend to reach the widest market available to any mobile platform. For me, performance is a big deal for all of the mobile gaming I partake in. I never came across jank or stutters that left me waiting for the phone to react to my inputs.

With a 4,mAh battery, this phone basically outputs exactly what I suspected. However, I made up for all of that WiFi usage by using the camera and gaming a lot, so the fact that I was easily getting through entire days with hours of screen on time is just fine in my book.

The three rear-facing and two front-facing cameras are the only things that concern me on this phone. When it notices this, it snaps a burst of shots then compiles them into a single image, with what should be decent lighting. Sadly, it typically turns out looking like a muddy mess. Scene Optimizer will also recognize if the phone has been placed on a tripod. When this is done and in low light, the camera will snap even more photos to compile them into a single shot.

I have a few low-light examples below. This same low-light performance is seen on the front-facing cameras, too. The photos are completely unusable. Come on, Samsung!

When you have proper lighting, the Galaxy S10 and its array of cameras shine. I notice that purples look incredible, as well as greens. In good light, contrast and details are exceptionally fine, too. Also great is the addition of the ultra wide lens. I love this thing. This is not a cheap phone. Everything else is basically the same. My only real concern, not including the slight camera hiccups I ran into, would be updates.
