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.app.Activity;import android.os.Bundle;import android.util.Log;import android.view.GestureDetector;import android.view.GestureDetector.OnGestureListener;import android.view.MotionEvent;import android.view.View;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;public class FlipperDemo extends Activity implements OnGestureListener {private ViewFlipper flipper;private GestureDetector detector;private TextView tv1, tv2, tv3;private Spinner sp1, sp2, sp3;private ImageView im1, im2, im3;private

(ImageView) findViewById(R.id.im2);im3 = (ImageView) findViewById(R.id.im3);detector = new GestureDetector(this);flipper = (ViewFlipper) findViewById(R.id.myFilpper);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());Log.e("myTag", dbManager.findCitiesByIDs(dbManager.findCityIdByWebID(1)).toString());adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, citys1);// 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sp1.setAdapter(adapter);//

(dbManager.getCityCount() == 0) {City[] cities = new City[] { new City("苏州", "suzhou"),new City("北京", "beijing"), new City("郑州", "zhengzhou"),new City("广州", "guangzhou"), new City("深圳",
