Another expensive operation to create a list item component is to call the findViewById () method. This method goes deep into the loaded rows and extracts the corresponding components from the specified identifier, making it easy to modify the contents of the list item components, such as modifying the text of the TextView. Since the findViewById () method can find components from all the subcomponents in the root view of the row, you may need to execute quite a few instructions, and this is even true when you repeat the same component.
