While in the text editor, you can also view the Palette, Component Tree, and design editor by clicking Preview on the right side of the window. A baseline constraint lets you constrain the elements so that the text baselines match. With constraints removed, you can move and resize the elements on the layout freely. It can help us to translate strings, replace icons, redesign layouts, remove ads, remove limitation in free version, etc.
You can then modify these changes as needed. The design editor can preview your layout on different Android devices and versions, and you can dynamically resize the layout to be sure it works well on different screen sizes. . If you're working through this codelab on your own, feel free to use these homework assignments to test your knowledge. To search for a specific view attribute, click View all attributes and then click Search at the top of the window. In this task you will learn an easier way to create variants of your layout for horizontal also known as landscape and vertical also known as portrait orientations for phones, and for larger displays such as tablets. You can type it in Directory name or select from the Available qualifiers list, one at a time, and click Add.
For an overview of the course, including links to the concept chapters, apps, and slides, see. Note that you can choose sample text via the Design-time View Attributes window only if the text attribute is empty. As shown on the right side of the figure above 2 , you can click the view inspector's width control, which appears in two segments on the left and right sides of the square, until it shows Wrap Content. This attribute is useful if you want your app to work on devices that use different language or locale preferences. For example, if two Button elements each have a weight of 1 and a TextView 2, totaling 4, the Button elements get ¼ of the space each, and the TextView half.
Click this button to display the Design-time View Attributes window, as shown in figure 4. To gain more practice with ConstraintLayout, you will create a variant of this layout for horizontal orientation as shown in the figure below. This toolbar is also available in the text editor's Preview window. A TextView with sample data In an ImageView, you can choose between different sample images. For example, choose Nexus 4, Nexus 5, and then Pixel to see differences in the previews.
As you place a view in the layout, the editor the editor displays information about the view's relationship with the rest of the layout. The start is the left edge of the screen if the preference is left-to-right, or it is the right edge of the screen if the preference is right-to-left. This list displays only the languages available in the string resources see the lesson on localization for details on how to add languages. When the LinearLayout is the root View, it expands to the size of the screen the parent View. To see both panes side by side, select Design + Blueprint.

Probably has the ability to assist us to work things like string localization, substitution of a noble image, layout configuration, architecture and including exclusion advertising, permits removal, etc. However, to use it well, we need a little bit professional skills. It can help us to do things like string localization, background image replacement, layout re-architecting, and even ad eliminating, permission removing, etc. To view the error details, click the icon. Try to change the signature of the original application.

The Button elements expand horizontally to fill the layout as shown below.
To find the next practical codelab in the Android Developer Fundamentals V2 course, see. For example, if the Button elements each have a weight of 1 and the TextView 2, totaling 4, the Button elements get ¼ of the space each, and the TextView half. To see all known issues in a window below the editor, click Show Warnings and Errors or in the toolbar. Refer to the figures below for the layout.
