The purpose and requirements of the experiment (the knowledge points which are involved in this experiment and are required to be mastered)

Purpose

1. Learn how to use color and string resources in Android.
2. Understand how size and layout resources are used in Android.

Requirements

1. Use color resources for activity and view in project;
2. Use string resources and understand the reference mechanism of string resources;
3. Set the dimensions for the view components in Android;
4. Use layout resources to place components on the interface at the specified location.

second, the experimental environment (the hardware equipment and related software used in this experiment)

(1) PC Machine

(2) Operating system: Windows XP

(3) Software: Eclipse, jdk1.6,android Sdk,adt

Third, the contents and steps of the experiment

Process

1. Create a project

2. Modifying string resources

Open the/res/values/strings.xml file.

Click the Add button to add a string, enter the string name and value

A new project contains three existing strings

3. New color resource color.xml

4. using resource colors and string resources

Four, the experimental results (the experimental source program list and operating results or experimental conclusions, experimental design drawings)

Five, Experimental summary (analysis of the results of the experiment, experience and improvement of experimental ideas)

After this experiment, you can learn more about the use of Android experiment color, string resources, but the specific structure of Android still do not understand, in the future need to see more, more practice.
