5 Layouts in Android

1, LinearLayout

The default orientation is horizontal

Note the relationship between android:orientation= "horizontal" and android:layout_gravity= "" in Match_parent or wrap_content

Layout_gravity operation is the layout of the component gravity= "right" is the component's contents

2, Relativelayout

Child controls are independent of each other and are left-aligned by default

Android:layout_centerhorizontal= "true"

Android:layout_centervertical= "true"

Android:layout_centerinparent= "true"

Android:layout_alignparentleft= "true"

android:layout_toleftof= "@id/center"

android:layout_below= "@id/center"

3, Framelayout

Because there is no direction, so android:layout_gravity= "bottom" up or down can be effective

Note: Framelayout must be used in Tabhost

4, Tablelayout

Tablelayout in android:stretchcolumns= "1": Specify which column stretches to fill the remaining space

The columns in the Tablelayout are aligned by default

TableRow represents a row, and several child nodes represent a few columns

The immediate child nodes of the tablelayout default layout_width= "Match_parent" and layout_height= "wrap_content" and cannot be modified

The immediate child nodes of the TableRow default layout_height= "Wrap_content" and Layout_width= "wrap_content" and cannot be modified

layout_column= "1" sets the current component to the first column

layout_span= "2" current column occupies two columns of space

5, Absolutelayout Absolute layout

Layout_x and Layout_y Specify where the space is located

When you do not need to do a screen fit for a platform or a device, you may use
