順序是： OneAcitivity -->MainActivity -> TwoActivity

然后第2次進去就是：OneActivity -> TwoActivity

代碼里都有注釋的了，這里就不多說了。
OneActivity的代碼如下：

[java]

復制代碼代碼如下:

package cn.djy.activity;

最后是TWOActivity：這個Activity是顯示的內容。

[java]

復制代碼代碼如下:

package cn.djy.activity;

import android.app.Activity;
import android.os.Bundle;

public class TwoActivity extends Activity{


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.end);
    }

}

package cn.djy.activity;

import android.app.Activity;
import android.os.Bundle;

public class TwoActivity extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.end);
}

}

主要代碼完成。
里面涉及的drawable圖片是小圓點圖片。

下面貼出XML的。

start.xml

[css]

復制代碼代碼如下:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
     <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:id="@+id/linear_viewpager">

        <android.support.v4.view.ViewPager   android:id="@+id/guidePages" android:layout_width="fill_parent" android:layout_height="wrap_content"/>

     </LinearLayout>



     <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:id="@+id/linear_circle">

         <RelativeLayout android:layout_width="fill_parent" android:layout_height="wrap_content" >
                <LinearLayout android:id="@+id/icon_circle"
                              android:layout_width="fill_parent"
                              android:layout_height="wrap_content"
                              android:layout_marginBottom="40dip"
                              android:layout_alignParentBottom="true"
                              android:gravity="center_vertical"
                              android:orientation="horizontal"/>
         </RelativeLayout>

     </LinearLayout>

</FrameLayout>

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
   <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:id="@+id/linear_viewpager">

    <android.support.v4.view.ViewPager android:id="@+id/guidePages" android:layout_width="fill_parent" android:layout_height="wrap_content"/>

   </LinearLayout>
   <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:id="@+id/linear_circle">

     <RelativeLayout android:layout_width="fill_parent" android:layout_height="wrap_content" >
       <LinearLayout android:id="@+id/icon_circle"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="40dip"
            android:layout_alignParentBottom="true"
            android:gravity="center_vertical"
            android:orientation="horizontal"/>
     </RelativeLayout>

   </LinearLayout>

</FrameLayout>

其實是用Group把子項包起來作為顯示：

那子項為：
viewpager_page1.xml

[css]

復制代碼代碼如下:

viewpager_page2.xml

[css]

復制代碼代碼如下:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center">

<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="pages222222222222222222"></TextView>

<Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="asdfi14234124" android:id="@+id/bt_close"></Button>
</LinearLayout>
