Additionally, design mode avoids the need to learn the intricacies of the various property values of the Android SDK view classes. There are, however, advantages to using design mode.įirst, design mode will generally be quicker given that it avoids the necessity to type lines of XML. When to write XML manually as opposed to using the Layout Editor tool in design mode is a matter of personal preference. Viewed from within the Preview panel of the Layout Editor in Text mode, the above layout will be rendered as shown in Figure 21-1: Additionally, the wrap_content height and width properties have been declared on both objects so that they are sized to accommodate the content (in this case the text referenced by the string resource value). Both views have been assigned IDs and configured to display text strings represented by string resources named button_string and text_string respectively. The following modifications add opposing constraints connected to the parent layout to center the widget horizontally, together with a constraint connecting the bottom of the TextView to the top of the button with a margin of 72dp: Īlso, note that the Button and TextView views have a number of attributes declared. Once again, the absence of constraints on the newly added TextView will cause it to appear in the top left-hand corner of the layout at runtime. The following modification, for example, adds a TextView widget to the layout: To add a second widget to the layout, simply embed it within the body of the ConstraintLayout element. Note that each of the constraints is attached to the element named activity_main which is, in this case, the parent ConstraintLayout instance. If opposing constraints are added to the sides of the button, however, it will appear centered within the layout: At runtime, therefore, the button will appear in the top left-hand corner of the screen (though indented 16dp by the padding assigned to the parent layout).

You are reading a sample chapter from the Android Studio 3.2 Edition of this book. In the following example a Button widget has been added as a child of the ConstraintLayout: Use dp in preference to this unit.Īny children that need to be added to the ConstraintLayout parent must be nested within the opening and closing tags. Use is not recommended since different displays will have different pixels per inch. Similar to dp but scaled based on the user’s font preference.

An abstract unit of measurement based on the physical density of the device display relative to a 160dpi display baseline. Any specification of spacing in an Android layout must be specified using one of the following units of measurement: Note that in the above example the layout element is also configured with padding on each side of 16dp (density independent pixels). The following XML, for example, declares a ConstraintLayout view as the root element, assigns the ID activity_main and sets match_parent attributes such that it fills all the available space of the device display: This is represented by both opening and closing tags and any properties that need to be set on the view. This declaration should be followed by the root element of the layout, typically a container view such as a layout manager. The first line of an XML resource file should ideally include the following standard declaration:
