Question

What is the difference between linear and relative layout?

Answer 1

Line layouts place each child one by one in a line horizontally or vertically. With a relative layout, you can give each child a LayoutParam that determines exactly where it should go, relative to the parent or relative to other children.

Answer 2

LINEAR LAYOUT ::

• In the linear layout, as in the case of the name, all elements are displayed linearly
• Either horizontally or vertically, and this behavior is set in android: orientation, which is an attribute of node LinearLayout.
• Line layouts place each child, one by one, in a row, either horizontally or vertically.

RELATIVE LAYOUT::

• In relative position, each element is ordered relative to another element or parent element.
• This is useful when adding views one next to the other, etc.
• With a relative layout, you can give each child a LayoutParam that accurately indicates where it should go, relative to the parent or compared to other children.
• Views overlap in relative layout

Optimization :: See Optimizing Layout Hierarchy

The less views, the better :

• The number one goal for your layouts should be using the fewest number of Views possible. The fewer Views you have to work with, the faster your application will run. Excessive nesting of Views further slows down your application.

• A RelativeLayout hierarchy will typically use fewer Views and have a flatter tree than a LinearLayout hierarchy. With LinearLayout, you must create a new LinearLayout every time you want to change the orientation of your views – creating additional Views and a more nested hierarchy. As a result, it is recommended that you first use RelativeLayout for any layout that has any complexity. There is a high probability you will reduce the number of Views – and the depth of your View tree – by doing so.

Answer 3

From Android Developer Documentation: General Layout Objects

Linearlayout

LinearLayout aligns all children in one direction — vertically or horizontally, depending on how you define the orientation attribute.

RelativeLayout

RelativeLayout allows child views to indicate their position relative to the parent view or to each other (ID specified)

Answer 4

The following link should visually explain how layouts work "Visually"

Add some components to the window and clutter with the layouts to find out what happens, as I learned what everyone is doing.

Answer 5

One of the features in LinearLayout in Android is a property called Weight , which application can specify using android:layout_weight . This attribute assigns importance to the view in terms of how much space it should occupy on the screen.

RelativeLayout , on the other hand, does not support weight or, in other words, RelativeLayout does not pay attention to android:layout_weight . This is a property of LinearLayout.LayoutParams , but not RelativeLayout.LayoutParams .

Answer 6

In a relative layout, the entire contents of the layout page are associated with other contents on the example_layout.xml page

In the case of linear layout, elements are displayed in linear format.

Answer 7

The difference between the linear and relative layout in android is that in the linear layout, children can be placed either horizontally or vertically, but with relative layout, children can be located at a relative distance from each other. This is the difference between linear and relative layouts.

Answer 8

the difference is simple: in LinearLayout we arrange the material linearly (one after another), and in RelativeLayout we can place things anywhere on the screen.

=> The linear layout is organized as a list. The rest are similar in functionality.

Answer 9

Line layouts

• Line layouts are great for aligning views in rows and columns.
• This is a good way to split one place using layouts that will expand or shrink depending on the size of the Display.

Relative layouts

• Relative layouts are great for positioning elements relative to each other.
• For example, put B below A or put C in the lower left corner. Check Screen Capture
• Relative layout also makes it easy to overlap views. For example: view A is overlapping view B. Check screen shielding
