This post will cover layout issues when creating native applications for android. That layout, which is described in xml files from the res / layout / directory. So, let's begin:
There are five standard types of layout:

• AbsoluteLayout
• Framelayout
• Linearlayout
• RelativeLayout
• Tablelayout

AbsoluteLayout

(not recommended to use, deprecated)
AbsoluteLayout - means that each layout element will have an absolute position relative to the upper left corner of the screen, specified using x and y coordinates. Those. the top left corner of the screen with AbsoluteLayout has coordinates x = 0, y = 0.
The position is indicated in the attributes of the android: layout_x and android: layout_y element.
Code example:

<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Button android:id="@+id/backbutton" android:text="Back" android:layout_x="10px" android:layout_y="5px" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:layout_x="10px" android:layout_y="110px" android:text="First Name" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <EditText android:layout_x="150px" android:layout_y="100px" android:width="100px" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:layout_x="10px" android:layout_y="160px" android:text="Last Name" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <EditText android:layout_x="150px" android:layout_y="150px" android:width="100px" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </AbsoluteLayout> 

Framelayout

FrameLayout is a type of layout within which only one element per line can be displayed. Those. if inside FrameLayout you place several elements, then the next one will be displayed on top of the previous one.
Code example:

 <FrameLayout android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <ImageView android:src="@drawable/icon" android:scaleType="fitCenter" android:layout_height="fill_parent" android:layout_width="fill_parent"/> <TextView android:text="Learn-Android.com" android:textSize="24sp" android:textColor="#000000" android:layout_height="fill_parent" android:layout_width="fill_parent" android:gravity="center"/> </FrameLayout> 

Linearlayout

LinearLayout - type of layout in which the layout area is divided into lines and one element is placed on each line. The splitting can be vertical or horizontal, the type of splitting is indicated in the LinearLayout attribute android: orientation. Inside the layout it is possible to combine vertical and horizontal breakdowns, and in addition, a combination of several different types of layout is possible, for example using LinearLayout inside FrameLayout.
')
Vertical breakdown example for LinearLayout:

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> <Button android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> <Button android:id="@+id/button3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> </LinearLayout> 

LinearLayout horizontal layout example:

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> <Button android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> <Button android:id="@+id/button3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> </LinearLayout> 

Combination of several LinearLayout:

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> <Button android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> <Button android:id="@+id/button3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> <Button android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> <Button android:id="@+id/button3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> </LinearLayout> </LinearLayout> 

RelativeLayout

RelativeLayout - type of layout in which the positioning of elements occurs relative to each other and relative to the main container.
For how elements will be positioned are the following attributes:
Container Positioning Attributes

• android: layout_alignParentBottom - the bottom of the element is at the bottom of the container
• android: layout_alignParentLeft - The left side of the element is adjacent to the left side of the container
• android: layout_alignParentRight - The right side of the element is adjacent to the right side of the container
• android: layout_alignParentTop - The element is at the top of the container
• android: layout_centerHorizontal - the element is positioned in the center relative to the horizontal size of the container
• android: layout_centerInParent - The element is positioned in the center relative to the horizontal and vertical dimensions of the container size.
• android: layout_centerVertical - the element is positioned in the center relative to the vertical size of the container

Positioning attributes relative to other elements.
As the values ​​of these attributes, the element id is set relative to which positioning will be performed.

android: layout_above - Places the element above the specified
android: layout_below - Places the item below the specified
android: layout_toLeftOf - Arranges the item to the left of the specified
android: layout_toRightOf - Places the element to the right of the specified

Alignment relative to other elements.

android: layout_alignBaseline - Aligns the baseline of the element with the baseline of the specified element
android: layout_alignBottom - Aligns the bottom of the element with the bottom of the specified element
android: layout_alignLeft - Aligns the left edge of the element with the left edge of the specified element
android: layout_alignRight - Aligns the right edge of the element with the right edge of the specified element
android: layout_alignTop - Aligns the top of the element to match the top of the specified element

 <RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <Button android:id="@+id/backbutton" android:text="Back" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:id="@+id/firstName" android:text="First Name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/backbutton" /> <EditText android:id="@+id/editFirstName" android:width="100px" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toRightOf="@id/firstName" android:layout_below="@id/backbutton"/> <EditText android:id="@+id/editLastName" android:width="100px" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/editFirstName" android:layout_alignLeft="@id/editFirstName"/> <TextView android:id="@+id/lastName" android:text="Last Name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBaseline = "@id/editLastName" android:layout_below="@id/editFirstName" /> </RelativeLayout> 

Tablelayout

TableLayout - tabular layout.
Organizes elements into rows and columns of a table.
To organize the lines is the tag
