Getting Started with Android (v) Screen components 5.5 relativelayout relative layout

Using Relativelayout, you can specify the location of the child view that it contains by setting the relative position (where each view is relative to another view). Look at the code in the main.xml below:

<?xml version= "1.0" encoding= "Utf-8"?> <relativelayout xmlns:android= "http://schemas.android.com/apk/res/" Android "android:id=" @+id/rlayout "android:layout_width=" fill_parent "android:layout_height=" "Fill_parent" &    
       
    Gt <textview android:id= "@+id/lblcomments" android:layout_width= "Wrap_content" android:layou 
        t_height= "Wrap_content" android:layout_alignparentleft= "true" android:layout_alignparenttop= "true" android:text= "Comments"/> <edittext android:id= "@+id/txtcomments" Android: 
        Layout_width= "Fill_parent" android:layout_height= "170px" android:layout_alignleft= "@+id/lblcomments" android:layout_below= "@+id/lblcomments" android:layout_centerhorizontal= "true" android:textsize= "1 
        8sp "/> <button android:id=" @+id/btnsave "android:layout_width=" 125px " Android:layout_height= "Wrap_content" android:layout_alignright= "@+id/txtcomments" android:layout_below= "@+id" 
        /txtcomments "android:text=" Save "/> <button android:id=" @+id/btncancel " Android:layout_width= "124px" android:layout_height= "wrap_content" android:layout_alignleft= "@+id/txtC Omments "android:layout_below=" @+id/txtcomments "android:text=" Cancel "/> </relativela Yout>

As you can see, these views are embedded in the relativelayout, and each view has some unique properties to align with the other view. These properties are:

Layout_alignparenttop

Layout_alignparentleft

Layout_alignright

Layout_below

Layout_centerhorizontal

The values of these properties are the IDs of each referenced view.
