As mentioned in the Introduction section, RelativeLayout allows Views to be position-relative to each other and the parent. RelativeLayout is particularly useful for reducing the number of nested layouts, which is very important for reducing memory and processing requirements.
Create a new project and call it RelativeLayout. Android Studio defaults to using a ConstraintLayout , which we will replace with a RelativeLayout for this example. Use the default Phone & Tablet settings on the Target Android devices and select Empty Activity on the Add an Activity to Mobile dialog.
- Open the
res/layout/activity_main.xmlfile and change it as follows:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height...
