The absolute layout of AbsoluteLayout is similar to that. NET Winform layout, with the coordinate point in the upper left corner of the form, extending to the right. since the absolute layout of each control is fixed and cannot be changed with the screen size, the running effect on different devices is different, so this layout method is used less.

The controls in the absolute layout AbsoluteLayout have two important attributes: layout_x and layout_y, respectively, used to set the absolute position of the control.

Let's take a look at the layout effect of this example.

<? Xml version = "1.0" encoding = "UTF-8"?> <AbsoluteLayout xmlns: android = "http://schemas.android.com/apk/res/android" android: layout_width = "match_parent" android: layout_height = "match_parent"> <ImageView android: id = "@ + id/imageView1" android: layout_width = "96dp" android: layout_height = "96dp" android: layout_x = "0dp" android: layout_y = "3dp" android: src = "@ raw/pad"/> <TextView android: id = "@ + id/textView2" android: layout_width = "120dp" android: layout_height = "wrap_content" android: layout_x = "110dp" android: layout_y = "78dp" android: text = "color: White"/> <TextView android: id = "@ + id/textView2" android: layout_width = "120dp" android: layout_height = "wrap_content" android: layout_x = "110dp" android: layout_y = "47dp" android: text = "product price: $19 "/> <TextView android: layout_width =" 120dp "android: layout_height =" wrap_content "android: layout_x =" 110dp "android: layout_y =" 16dp "android: text = "Product Name: Ipad Air"/> <TextView android: id = "@ + id/textView1" android: layout_width = "match_parent" android: layout_height = "3dp" android: layout_x = "0dp" android: layout_y = "118dp" android: background = "# EEE8CD" android: text = ""/> <ImageView android: id = "@ + id/ImageView01" android: layout_width = "96dp" android: layout_height = "96dp" android: layout_x = "9dp" android: layout_y = "137dp" android: src = "@ raw/pad"/> <TextView android: layout_width = "120dp" android: layout_height = "wrap_content" android: layout_x = "118dp" android: layout_y = "144dp" android: text = "item name: Ipad Air"/> <TextView android: id = "@ + id/TextView01" android: layout_width = "120dp" android: layout_height = "wrap_content" android: layout_x = "118dp" android: layout_y = "206dp" android: text = "color: White"/> <TextView android: id = "@ + id/TextView01" android: layout_width = "120dp" android: layout_height = "wrap_content" android: layout_x = "118dp" android: layout_y = "176dp" android: text = "product price: $19"/> <TextView android: id = "@ + id/TextView02" android: layout_width = "match_parent" android: layout_height = "3dp" android: layout_x = "2dp" android: layout_y = "261dp" android: background = "# EEE8CD"/> </AbsoluteLayout>

For: android: id = "@ + id/AbsoluteLayout01", what I learned when I learned linear layout?

This is the definition of a component id. the id of this component is defined as AbsoluteLayout01.
You can use findViewById (R. id. AbsoluteLayout01) in the code to obtain this component object.

In addition, we can see from your id that this component is a layout component of AbsoluteLayout.

How can applications developed with AbsoluteLayout layout adapt to various screens?

What can I do without overall amplification? As we have already done this, all the elements at that time were a bit like games, and they were not quite implemented with other la S.
