Containers
Containers:
Containers generally refer to various layout elements and view groups used to organize and arrange UI components within an app's user interface.
Containers are crucial for creating a visually appealing and functional layout.
Some commonly used Android containers:
LinearLayout:
Organizes child views in a single line, either horizontally or vertically.
Attributes: android:orientation, android:gravity, android:layout_weight, etc.
RelativeLayout:
Positions child views relative to each other or relative to the parent.
Attributes: android:layout_below, android:layout_alignParentTop, android:layout_centerInParent, etc.
FrameLayout:
Places child views on top of each other, occupying the whole frame.
Typically used for displaying a single item at a time.
Commonly used for fragments.
Attributes: None specific to FrameLayout.
ConstraintLayout:
Allows defining relationships (constraints) between views to create complex layouts.
Supports flat view hierarchies, improving performance.
Attributes: app:layout_constraintTop_toTopOf, app:layout_constraintStart_toStartOf, etc.
GridLayout:
Organizes child views in a grid.
Allows specifying the number of rows and columns.
Attributes: android:layout_row, android:layout_column, etc.
TableLayout:
Organizes child views in rows and columns.
Attributes: android:layout_span, android:stretchColumns, etc.
ScrollView:
Provides a scrollable view that can contain a single child.
Useful when the content is too large to fit on the screen.
Attributes: None specific to ScrollView.
HorizontalScrollView:
Similar to ScrollView but scrolls horizontally.
Attributes: None specific to HorizontalScrollView.
NestedScrollView:
Extends ScrollView and supports nested scrolling.
Useful when dealing with scrolling within scrollable views.
Attributes: None specific to NestedScrollView.
DrawerLayout:
Implements a navigation drawer that slides in from the left or right.
Commonly used for navigation menus.
Attributes: android:layout_gravity, android:layout_width, etc.
CoordinatorLayout:
Provides a top-level container for coordinating animations and transitions between child views.
Often used in conjunction with AppBarLayout for Material Design.
Attributes: None specific to CoordinatorLayout.
AppBarLayout:
A vertical LinearLayout that implements many of the features of the Android app bar concept, namely scrolling gestures.
Often used with CollapsingToolbarLayout for flexible app bar layouts.
Attributes: None specific to AppBarLayout.
These containers enable the developers to design the interfaces that are efficient, real time as well as are effective in terms of aesthetics.
Selection of an ideal container depends on layout constraints, and general appearance or feel of the application at hand.
By blending multible containers application developers are able to orginze Android applications into infinite textures and logical structures.
