In Android, we normally use the R class in order to gain access to the drawable, layout, string (and others) variables.
I made this helper method to get a resource id dynamically. However, if you have no need for this, it is a better option to use the R class directly as the search operation is quicker compared to this.
Here is a sample code to load XML layout files at runtime within your Android application. Basically, you have to have a Layout tag within your main XML file so that we get to have a placeholder to where we want to store our content.
where a is the class that extends Activity. If you are going to place this code within your class that extends Activity, you don’t need to include the a. in the code. Of course, this does not restrict to LinearLayout alone. You can use all other layouts to add new Views as its content.
