XML layout file

The layout file in xml format is stored in the folder res/layout

The layout methods are mainly LinearLayout (linear layout) and TableLayout (table layout) , RelativeLayout (relative layout)

Of course, there are also AbsoluteLayout, (absolute layout), FrameLayout (frame layout), etc.

They can also be nested to achieve better interface effects

I have sorted out the commonly used attributes based on my personal understanding

It may not be scientific but I think it is very practical.

Control is the whole:

android: ID address

android: width width

android: Height height

android: layout_width width (fill_parent/wrap_content)

android:layout_height (fill_parent/wrap_content)

android:layout_margin(Left/Top/Right/Bottom) Margin (*dip)

Android: Layout_weight.

android:background                                                                                                                                                                . Contents are displayed together (true /false)

Relative layout:

android:layout_above                                                                                                                                               or                     but                                                                Whose bottom edge the edge is aligned with (id)

Android: Layout_toleftof to the right side to align with the left side (ID)

android: layout_torightof to the right side of the right side (ID)

android: layout_aligntop. Alignment ( ID)

Android: Layout_alignbottom. Align with. Who is the right side? The right alignment (id)

android:layout_alignParentTop The top is aligned with the top of the parent control (true/false)

android:layout_alignParentBottom The bottom is aligned with the bottom of the parent control (true/false) True/False)

android: layout_alignparentLeft left to the left side of the parent control (TRUE/FALSE)

android: Layout_alignparentrid to the right of the parent control (TR. UE/FALSE)

android: layout_centerinparent relative to the parent control (True/False)

Android: Layout_CenterHorizontal relative to the level of the parent control level (True/False)

## android: Layout_centervertical Relative to the parent control (True/False)
