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 {

		im2 = (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,

		// 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);
		// 定义子元素选择监听器
		// 为下拉列表绑定事件监听器
		sp1.setOnItemSelectedListener(new OnItemSelectedListener() {
			@Override
			public void onItemSelected(AdapterView<?> parent, View view,
					int position, long id) {
				im1.setImageResource(getIcon(dbManager
						.findCityPicByCityName(sp1.getSelectedItem().toString())));
			}

			@Override
			public void onNothingSelected(AdapterView<?> parent) {
			}
		});

		citys2 = dbManager.findCitiesByIDs(dbManager.findCityIdByWebID(2));
		adapter = new ArrayAdapter<String>(this,
				android.R.layout.simple_spinner_item, citys2);
		// 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
		sp2.setAdapter(adapter);
		// 定义子元素选择监听器

		sp3.setOnItemSelectedListener(new OnItemSelectedListener() {
			@Override
			public void onItemSelected(AdapterView<?> parent, View view,
					int position, long id) {
				im3.setImageResource(getIcon(dbManager
						.findCityPicByCityName(sp3.getSelectedItem().toString())));
			}

			@Override
			public void onNothingSelected(AdapterView<?> parent) {
			}
		});
	}

	private int getIcon(String cityName) {
