The android.content.res package library in Android provides support for resources commonly used in Android applications, such as images, strings, and dimensions. The TypedArray class in this package library is used to obtain an array of styled attribute information.
The getDimension() method of the TypedArray class is used to retrieve the value of a dimension attribute in the array. This method returns a float value that represents the dimension in pixels. Here are some code examples that use the getDimension() method:
Example 1: Retrieve the dimension value of a TextView's text size attribute
This example obtains the TypedArray for the textSize attribute of an Android TextView widget. The getDimension() method is then called to retrieve the value of the attribute. Note that the second parameter of the getDimension() method sets a default value to return if the attribute is not defined in the array.
Example 2: Retrieve the dimension value of a custom attribute in a custom view
In this example, a custom view is created and its attribute set is defined in attrs.xml. The custom view attribute is then obtained using the TypedArray's getDimension() method.
The android.content.res package library is part of the Android SDK, which is included in the default package of the Android Studio IDE.
