A brief analysis of the linear layout linearlayout examples of Android programming _android

This example describes the linear layout linearlayout usage of Android programming. Share to everyone for your reference, specific as follows:

Linear layout (LinearLayout)

You can have its child elements line up vertically or horizontally (the default is in the vertical direction without setting the orientation).

The following examples are main.xml modified on the basis of others:

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android= "http://schemas.android.com/apk/res/" Android "Android:layout_width=" Fill_parent "android:layout_height=" fill_parent "android:orientation=" vertical " > <linearlayout android:orientation= "Horizontal" android:layout_width= "Fill_parent" Android:layout_hei ght= "Wrap_content" android:baselinealigned= "false" android:layout_weight= "1" > <linearlayout Andro id:orientation= "Horizontal" android:layout_width= "Wrap_content" android:layout_height= "Fill_parent" Andr oid:layout_weight= "1" > <textview android:text= "@string/color_green" android:textcolor= "#ff0000 "Android:background=" #00aa00 "android:layout_width=" wrap_content "android:layout_height=" Fill_par Ent "android:layout_weight=" 1 "/> <textview android:text=" @string/color_blue "android:b Ackground= "#0000aa" Android:laYout_width= "Wrap_content" android:layout_height= "Fill_parent" android:layout_weight= "1"/> </Line

    Android:layout_width= "Fill_parent" android:layout_height= "Wrap_content" android:layout_weight= "2"/> <textview android:text= "@string/color_white" android:textcolor= "#ff0000" android:background= "#ffffff 
  "Android:layout_width=" fill_parent "android:layout_height=" Wrap_content "android:layout_weight=" 2 "/>

 </LinearLayout> </LinearLayout>

String.xml

<?xml version= "1.0" encoding= "Utf-8"?>
<resources>
  <string name= "Hello" >hello world, testabsolutelayoutactivity!</string>
  <string name= "App_name" >TestAbsoluteLayout</string>
  <string name= "color_red" >red</string>
  <string name= "Color_green" >green</string>
  <string name= "Color_blue" >blue</string>
  <string name= "Color_white" >white</string >
  <string name= "Color_black" >black</string>
  <string name= "Color_yellow" >yellow</ string>
  <string name= "Color_unknown" >unknown</string>
</resources>

The effect chart is as follows:

Common Properties:

Android:orientation: You can set the direction of the layout
android:gravity: Used to control the alignment of components
layout_weight: controls the relative size of each component in the layout
