The advantages and disadvantages of the monitor in the layout of Android development in the simple completion of multiple controls

First of all, add the following sentence to a control: android:onclick= "DoClick"//doclick is a method name, you can customize

Then write a DoClick method in the activity:

public void DoClick (view view) {

Multiple Controls with

Switch (View.getid ()) {

Case R.ID.XX:

Break

...
}
