2、数值配置文件

<?xml version="1.0" encoding="utf-8"?>
    <resources>
    
        <string name="hello">Hello World, MainActivity!</string>
        <string name="app_name">Sms</string>
        <string name="number">请输入手机号码</string>
        <string name="content">请输入短信内容</string>
        <string name="button">发送</string>
        <string name="sucess">发送成功</string>
    
        <string name="table_layout_4_open">Open</string>
        <string name="table_layout_4_open_shortcut">OpenShortcut</string>
        <string name="table_layout_4_save">Save</string>
        <string name="table_layout_4_save_shortcut">SaveShortcut</string>
    </resources>

3、R.java资源类文件

/* AUTO-GENERATED FILE.  DO NOT MODIFY.
     *
     * This class was automatically generated by the
     * aapt tool from the resource data it found.  It
     * should not be modified by hand.
     */
    
    package cn.huangjie.layout;
    
    public final class R {
        public static final class attr {
        }
        public static final class drawable {
            public static final int ic_launcher=0x7f020000;
            public static final int movie=0x7f020001;
            public static final int play=0x7f020002;
        }
        public static final class id {
            public static final int button=0x7f050003;
            public static final int contentEdit=0x7f050002;
            public static final int numberEdit=0x7f050001;
            public static final int numberlabel=0x7f050000;
        }
        public static final class layout {
            public static final int frame=0x7f030000;
            public static final int linear=0x7f030001;
            public static final int table=0x7f030002;
        }
        public static final class string {
            public static final int app_name=0x7f040001;
            public static final int button=0x7f040004;
            public static final int content=0x7f040003;
            public static final int hello=0x7f040000;
            public static final int number=0x7f040002;
            public static final int sucess=0x7f040005;
            public static final int table_layout_4_open=0x7f040006;
            public static final int table_layout_4_open_shortcut=0x7f040007;
            public static final int table_layout_4_save=0x7f040008;
            public static final int table_layout_4_save_shortcut=0x7f040009;
        }
    }

4、窗口显示程序

package cn.huangjie.layout;
    
    import android.app.Activity;
    import android.os.Bundle;
    
    public class LayoutActivity extends Activity {
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
    //        setContentView(R.layout.linear);
    //        setContentView(R.layout.table);
            setContentView(R.layout.frame);
        }
    }
