android 引导界面的实现方法


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;

            mHandler.sendEmptyMessageDelayed(SWITCH_GUIDACTIVITY,4000);

    }
}

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"
    >
     <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">

  <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>

<?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>
