复制代码代码如下:

/**

* 实现

* @author dujinyang

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:

package cn.djy.activity;

import android.app.Activity;

import android.content.Context;

import android.content.Intent;

import android.os.Bundle;

@Override

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

setContentView(R.layout.one);

boolean flag=this.isFirstEnter(getApplicationContext(), this.getClass().getName());

if(flag)

mHandler.sendEmptyMessageDelayed(SWITCH_GUIDACTIVITY,4000);

else

mHandler.sendEmptyMessageDelayed(SWITCH_TWOACTIVITY, 4000);

}

private boolean isFirstEnter(Context context,String className){

if(context==null || className ==null || "".equalsIgnoreCase(className)) return false;

String mResultStr=context.getSharedPreferences(SHAREDPREFERENCES_NAME,Context.MODE_WORLD_READABLE).getString(KEY_GUIDE_ACTIVITY, "");

if(mResultStr.equalsIgnoreCase("false"))

return false;

else

return true;

}

//****************************************

intents.setClass(OneActivity.this,MainActivity.class);

OneActivity.this.startActivity(intents);

for (int i = 0; i < _imageViews.length; i++) {

_imageViews[position].setBackgroundResource(R.drawable.a2a);

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:

<?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"

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

</LinearLayout>

<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"

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

</LinearLayout>

<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:

<LinearLayout

xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent" android:orientation="vertical">

<TextView android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:text="adfasfasfweqwwfqw'"

</LinearLayout>

<LinearLayout

xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent" android:orientation="vertical">

<TextView android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:text="adfasfasfweqwwfqw'"

</LinearLayout>

viewpager_page2.xml

[css]

复制代码代码如下:

<?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">

</LinearLayout>

<?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">

</LinearLayout>
