The measured dimensions can be obtained by calling getMeasuredWidth and getMeasuredHeight. The second pair is simply known as width and height , or sometimes drawing width and drawing height. These dimensions define the actual size of the view on screen, at drawing time and after layout.
These values may, but do not have to, be different from the measured width and height. The width and height can be obtained by calling getWidth and getHeight. To measure its dimensions, a view takes into account its padding. The padding is expressed in pixels for the left, top, right and bottom parts of the view.
Padding can be used to offset the content of the view by a specific number of pixels. For instance, a left padding of 2 will push the view's content by 2 pixels to the right of the left edge. Even though a view can define a padding, it does not provide any support for margins. However, view groups provide such a support. Refer to ViewGroup and ViewGroup. MarginLayoutParams for further information. For more information about dimensions, see Dimension Values.
Each subclass of the ViewGroup class provides a unique way to display the views you nest within it. Below are some of the more common layout types that are built into the Android platform. Note: Although you can nest one or more layouts within another layout to achieve your UI design, you should strive to keep your layout hierarchy as shallow as possible. Your layout draws faster if it has fewer nested layouts a wide view hierarchy is better than a deep view hierarchy.
A layout that organizes its children into a single horizontal or vertical row. It creates a scrollbar if the length of the window exceeds the length of the screen.
Enables you to specify the location of child objects relative to each other child A to the left of child B or to the parent aligned to the top of the parent. When the content for your layout is dynamic or not pre-determined, you can use a layout that subclasses AdapterView to populate the layout with views at runtime. A subclass of the AdapterView class uses an Adapter to bind data to its layout.
The Adapter behaves as a middleman between the data source and the AdapterView layout—the Adapter retrieves the data from a source such as an array or a database query and converts each entry into a view that can be added into the AdapterView layout. You can populate an AdapterView such as ListView or GridView by binding the AdapterView instance to an Adapter , which retrieves data from an external source and creates a View that represents each data entry.
Android provides several subclasses of Adapter that are useful for retrieving different kinds of data and building views for an AdapterView. The two most common adapters are:. For example, if you have an array of strings you want to display in a ListView , initialize a new ArrayAdapter using a constructor to specify the layout for each string and the string array:. Then simply call setAdapter on your ListView :.
To customize the appearance of each item you can override the toString method for the objects in your array. Or, to create a view for each item that's something other than a TextView for example, if you want an ImageView for each array item , extend the ArrayAdapter class and override getView to return the type of view you want for each item. When you instantiate the SimpleCursorAdapter , pass the layout to use for each result, the Cursor containing the results, and these two arrays:.
The SimpleCursorAdapter then creates a view for each row in the Cursor using the provided layout by inserting each fromColumns item into the corresponding toViews view.
If, during the course of your app's life, you change the underlying data that is read by your adapter, you should call notifyDataSetChanged. This will notify the attached view that the data has been changed and it should refresh itself. You can respond to click events on each item in an AdapterView by implementing the AdapterView. OnItemClickListener interface. For example:. Layouts are used in the Sunflower demo app. Content and code samples on this page are subject to the licenses described in the Content License.
