Framelayout single frame layout, in a single frame layout of the entire interface as a blank alternate area, all the child elements can not be assigned to the position, they are all placed in the upper left corner of the area, and the following child elements directly over the preceding child elements, and the previous child elements part and all obscured.

The size of the framelayout is controlled by the largest child control in all the child controls that it adds. If the child controls are the same size, only the topmost child controls are visible at the same time, and others are obscured (the frame layout is used when the tab design is made). In Framelayout, the child controls are drawn through the stack, so the added child controls are drawn at the top.

Framelayout inherits the ViewGroup class, in addition to inheriting the properties and methods of the parent class, the Framelayout class also contains its own properties and methods:

Android:foreground (Setforeground (drawable)) sets the content drawn on top of all child controls.
Android:foregroundgravity (setforegroundgravity (int)) sets the Gravity property of the content that is drawn on all child controls.

The item in the Framelayout has these properties. (Less pathetic)
(1) Layout_width
(2) Layout_height
(3) Layout_marginleft
(4) Layout_margintop
(5) Layout_marginright
(6) Layout_marginbottom
(7) Layout_gravity

Here are some of the important attributes that Relativelayout uses:

First Class: Property value is True or False
Android:layout_centerhrizontal Horizontal Center
Android:layout_centervertical Vertical Center
Android:layout_centerinparent is completely centered relative to the parent element
Android:layout_alignparentbottom snaps to the bottom edge of the parent element
Android:layout_alignparentleft snaps to the left edge of the parent element
Android:layout_alignparentright snaps to the right edge of the parent element
Android:layout_alignparenttop snaps to the top edge of the parent element
android:layout_alignwithparentifmissing if the corresponding sibling element cannot be found, then the parent element is the reference.

Second class: The attribute value must be the reference name of the id "@id/id-name"
Android:layout_below at the bottom of an element
Android:layout_above at the top of an element
Android:layout_toleftof on the left side of an element
Android:layout_torightof on the right side of an element

Android:layout_aligntop aligns the top edge of this element with the top edge of an element
Android:layout_alignleft aligns the left edge of this element with the left edge of an element
Android:layout_alignbottom aligns the bottom edge of this element with the bottom edge of an element
Android:layout_alignright aligns the right edge of this element with the right edge of an element

Class III: Attribute values are specific pixel values, such as 30dip,40px
Android:layout_marginbottom distance from the bottom edge of an element
Android:layout_marginleft distance from the left edge of an element
Android:layout_marginright distance from the right edge of an element
Android:layout_margintop distance from the top edge of an element
