Android five layouts

This content is based on learning in the web, plus the understanding of yourself, write down the notes so that later to view

Layouts can be arranged in layout again

1. Linear layout (LinearLayout)

This layout controls the vertical/horizontal arrangement of controls

LinearLayout common to two properties

1, android:orientation= "vertical (vertical)"/"Horizontal (horizontal)"

2, android:gravity = "center"---this property controls the location of its subclasses (written at the beginning of the total)

(Common attributes are available)

1, center_vertical: Vertical Center

2, Center_horizontal: Horizontal Center

3, Center: horizontal vertical is centered

4. Right: The subclass control is on the left side of the current control

5. Left: Sub-class controls are located on the Ieft side of the current layout

6. The bottom sub-class control is below the current

A, android:gravity = "center"---this property controls the location of its subclasses

B, android:layout_gravity= ""--the value itself is in the XY position of the current parent container (written in the control)

C, android:layout_weight= "1"---value itself as the proportion of the current parent class container

2. Relative layout (relativelayout)---sub-controls and how subclasses are arranged relative to the parent container position

3. Frame Layout (framelayout)

Allows overlay placement between controls and controls, such as neon lights, progress bars

4. Absolute layout (absolutelayout)---also known as XY coordinate layout (not adaptive)

Less use in development, because the size of the phone is not the same, the development of software in different phones may not be beautiful

5. Table layout (tablelayout)
