Question

in android xml file, i often see two different format:

<TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/DrawableResources" />

OR

<TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/DrawableResources" ></TextView>

Are they the same? Are all the XML tag in android without contents between <TextView> and </TextView> can be written in the two format ?

Answer 1

Yes, it is a shortcut which I prefer using. However, some tags do use the long method such as LinearLayout and RelativeLayout and ScrollView to name a few as these examples accept content within themselves.

Have a read of the docs here: http://developer.android.com/guide/topics/ui/declaring-layout.html
