Final answer:
In Android Studio, widgets are added to a layout using the drag and drop method from the palette onto the layout canvas.
Step-by-step explanation:
In Android Studio, you can use the graphical editor to add widgets to a layout by dragging them from the palette onto your layout. This process is known as drag and drop. When you want to add an element such as a button, text field, or an image, you simply find the appropriate widget in the palette, which is a part of the Android Studio interface that contains categories of all the available widgets and view components you can add to your app's layout.
To use drag and drop, you click on the desired widget and while holding the mouse button, you move it over to the canvas where your layout is displayed. Once you have it in the desired position, you release the mouse button to place the widget into the layout. This makes designing the user interface (UI) visually intuitive and efficient.
This intuitive graphical editor feature simplifies UI design by allowing for easy placement and positioning of elements such as buttons, text fields, and images.
