android 引导界面的实现方法

复制代码 代码如下:


顺序是： OneAcitivity  -->MainActivity -> TwoActivity

然后第2次进去就是：oneActivity -> TwoActivity

代码里都有注释的了，这里就不多说了。
OneActivity的代码如下：

[java]
复制代码 代码如下:

     if(position!=i)
      _imageViews[i].setBackgroundResource(R.drawable.a1a);

   }
  }

    }
}

最后是TWOActivity：这个Activity是显示的内容。

[java]
复制代码 代码如下:
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);
 }

}

主要代码完成。
里面涉及的drawable图片是小圆点图片。

下面贴出XML的。

start.xml

[css]
复制代码 代码如下:

    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    

       

    

     

    

        
                                              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"/>
        

    

    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
  

   

  
  

    
                   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"/>
    

  



其实是用Group把子项包起来作为显示：

那子项为：
viewpager_page1.xml

[css]
复制代码 代码如下:
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"  android:orientation="vertical">
      />
 

  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"  android:orientation="vertical">
      />
 
 
viewpager_page2.xml

[css]
复制代码 代码如下:

  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">

 

 

  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">
