Android:gravity and Android:layout_gravity differences

As you can see from the name, Android:gravity is the element itself, where the text of the element itself is displayed in a different property setting, but not set by default on the left. Android:layout_gravity is relative to its parent element, stating where the element appears in the parent element.

<?xml version= "1.0" encoding= "Utf-8"?> 
<linearlayout xmlns:android= "Http://schemas.android.com/apk/res/android" 
android:orientation= "Vertical" 
Android:layout_width= "Fill_parent" 
android:layout_height= "Fill_parent"

<textview 
Android:layout_width= "Fill_parent" 
android:layout_height= "Wrap_content" 
android:text= "Gravity Horizontal Center" 
Android:textsize= "20dip" 
 android:gravity= "Center_horizontal"
android:background= "#666"/> 
<imagebutton 
android:layout_margintop= "10dip" 
Android:layout_marginbottom= "10dip" 
Android:id= "@+id/imagebutton01" 
android:src= "@drawable/android" 
Android:layout_width= "Wrap_content" 
android:layout_height= "Wrap_content" 
 android:layout_gravity= "Center_horizontal"> 
</ImageButton>

<textview
Android:layout_width= "Wrap_content"
android:layout_height= "Wrap_content"
android:layout_gravity= "right"
android:text= "layout_gravity Bureau right"
Android:textsize= "20dip"
android:background= "#666"/>
