The code in xml is as follows:

Reference to the implementation of graphical interface writing

Create a class that inherits the RelativeLayout layout we just did, dynamically load the layout we just set, and then write specific functions to complete the setting of a custom control.

We can see that we can load the layout file through Layoutinflater.from in the layout above, load three TextView controls in the constructor, and then write two implementation methods to assign values to the text box.

Implement loading custom layout

To convert to the layout file, we refer to the layout we have just defined, named titlelayout

Next, let's take a look at the effect of the implementation.
