why is there different id syntax in the Android docs?
- by darren
This page in the Android documentation defines an element id as follows:
<TextView android:id="@+id/label"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Type here:" />
However this page defines it as:
<EditText id="text"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:textColor="@color/opaque_red"
android:text="Hello, World!" />
I thought I had a decent understanding of what was going on until I saw this second example. In the first case, you need the + character so that id 'label' is added to the R file, correct? In the second case, would the EditText's id not be added to the R file because it does not contain the + character?
Also, the second example does not include the android namespace on the id. Does having or not having the Android namespace affect whether that id will be added to the R file?
Thanks for any clarification.
