android中炫酷划屏事件及sqlite全部操作Demo(1)

　　1、首先设计main.xml文件
　　


<?xml version="1.0" encoding="utf-8"?>
<ViewFlipper xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/myFilpper"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/red">
<TextView android:id="@+id/tv1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:textColor="@drawable/black"
android:textSize="30dip"/>
<Spinner android:id="@+id/sp1"
android:entries="@array/citys"
android:layout_gravity="center_horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<ImageView android:id="@+id/im1"
android:src="@drawable/icon"
android:layout_gravity="center_horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/green">
<TextView android:id="@+id/tv2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:textColor="@drawable/black"
android:textSize="30dip"/>
<Spinner android:id="@+id/sp2"
android:entries="@array/citys"
android:layout_gravity="center_horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<ImageView android:id="@+id/im2"
android:src="@drawable/icon"
android:layout_gravity="center_horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/blue">
<TextView android:id="@+id/tv3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:textColor="@drawable/black"
android:textSize="30dip"/>
<Spinner android:id="@+id/sp3"
android:entries="@array/citys"
android:layout_gravity="center_horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<ImageView android:id="@+id/im3"
android:src="@drawable/icon"
android:layout_gravity="center_horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
</ViewFlipper>
 　　2、编写界面切换是的效果（xml）
　　2.1、push_left_in.xml和push_left_out.xml
　　


<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="100%p" android:toXDelta="0"
android:duration="500" />
<alpha android:fromAlpha="0.1" android:toAlpha="1.0"
android:duration="500" />
</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="0" android:toXDelta="-100%p"
android:duration="500" />
<alpha android:fromAlpha="1.0" android:toAlpha="0.1"
android:duration="500" />
</set>
 　　2.2、push_right_in.xml和push_right_out.xml
　　


<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="-100%p" android:toXDelta="0"
android:duration="500" />
<alpha android:fromAlpha="0.1" android:toAlpha="1.0"
android:duration="500" />
</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="0" android:toXDelta="100%p"
android:duration="500" />
<alpha android:fromAlpha="1.0" android:toAlpha="0.1"
android:duration="500" />
</set>
 
 　　3、编写activity实现OnGestureListener接口

package com.jftt;
import java.util.List;

import android.util.Log;
import android.view.GestureDetector;
import android.view.GestureDetector.OnGestureListener;

import android.view.animation.AnimationUtils;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.Spinner;
import android.widget.TextView;
import android.widget.ViewFlipper;
import com.jftt.pojo.City;
import com.jftt.pojo.City_Web;
import com.jftt.pojo.WebSite;
import com.jftt.service.DBManager;

tv1.setText("拉手");
tv2.setText("淘宝");
tv3.setText("阿里巴巴");
citys1 = dbManager.findCitiesByIDs(dbManager.findCityIdByWebID(1));
Log.e("myTag", dbManager.findCityIdByWebID(1).toString());

adapter = new ArrayAdapter<String>(this,

// 设置下拉样式
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// 为下拉列表设置适配器

// 定义子元素选择监听器

// 定义子元素选择监听器
