一.设计思路

首先需要将XML文件进行解析，获取所需要的信息。主要是利用数据存储SQLite。把数据存储到数据库中，然后对其进行增删改查操作，对应日记本中的添加日记、删除日记、修改日记。基本功能实现后，对界面进行进一步的美化。

1．使用SQLiteOpenHelper(抽象类)来完成数据库的创建；

2.定义Diary的实体类与数据库访问类DiaryDao类，完成添加、删除、更新、按id查找、查找所有日记及日记总数的方法；

3.编写单元测试类并搭建单元测试的环境；

4.创建多个AndroidActivity和布局文件分别来实现对日记列表的显示、添加日记、修改日记、删除日记功能的布局和功能的实现；

5最后，添加闪屏效果，对所有界面进行美化。

二.开发过程用到的技术

1.在进行数据存储访问时使用SQLite的存储方式。

2. Android UI布局技术

主要运用控件：TabHost、EditText、Dialog、ImageView、ListView等

3.动画效果
设置切入动画：setInAnimation(AnimationUtils.loadAnimation(this,android.R.anim.animation)),通过注册监听事件来实现动画效果;
4. Intent页面跳转技术

Intent intent = new Intent(startActivity.this,endActivity.class);

5.项目闪屏效果

运用AlphaAnimation类通过设定其Alpha值实现渐变的动画效果，通过设定播

放时间控制动画的播放，通过注册事件监听控制当动画播放完毕自动跳转到主界

面。

6.ListView的判空效果

当ListView中为空时通过图片提示，提示效果明显。

在布局文件中要手动添加<ListView android:id=”@+id/listview”>

在Activity中

ListViewlist=(ListView)findViewById(R.id.listview);

ImageViewempty=(ImageView)findViewById(R.id.empty)；

Listview.setEmptyView(empty);

三.各个界面布局的实现

1.闪屏界面的布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"

android:background="@drawable/welcomm" >
<ProgressBar
android:id="@+id/progressBar1"

android:layout_gravity="center"/>
</LinearLayout>

4.日记编辑界面

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

四.具体实现

1.日记的实体类

package org.sql.entity;
public class Diary {
//最好与数据库中字段值一一对应
private Integer id;
private String content;
private String title;
private String createtime;
public Diary() {
super();
}
public Diary(String content, String title, String createtime) {
super();
this.content = content;
this.title = title;
this.createtime = createtime;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getCreatetime() {
return createtime;
}
public void setCreatetime(String createtime) {
this.createtime = createtime;
}
public String toString(){
return "Disry[title:"+title+",content:"+content+",createtime:"+createtime+"]";
}
}

2.DbHelper类

package org.sql.db;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
public class DbHelper extends SQLiteOpenHelper {
private static final String sql_NAME="mydb";
private static final int sql_Version=1;
public DbHelper(Context context) {
super(context, sql_NAME, null, sql_Version);
// TODO Auto-generated constructor stub
}
@Override
public void onCreate(SQLiteDatabase db) {
String sql = "create table diary(id integer primary key autoincrement,title varchar(20),content varchar(1000),createtime)";
db.execSQL(sql);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// TODO Auto-generated method stub
}
}

3.对数据库中的数据实现增删改查

package org.sql.Dao;
import java.util.ArrayList;
import java.util.List;
import org.sql.db.DbHelper;
import org.sql.entity.Diary;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
public class DiaryDao {
private Integer a;
private DbHelper dbhelper;
public DiaryDao(Context context){
dbhelper=new DbHelper(context);
}
public ArrayList<Integer> selectid(){
ArrayList<Integer> ids=new ArrayList<Integer>();
SQLiteDatabase db=dbhelper.getWritableDatabase();
String sql="select id from diary";
db.execSQL(sql);
Cursor cursor=db.rawQuery(sql, null);
while(cursor.moveToNext()){
a++;
ids.add(a);
}
return ids;
}
//插入数据
public void save(Diary diary){
SQLiteDatabase db=dbhelper.getWritableDatabase();
String sql="insert into diary(title,content,createtime)values(?,?,?)";
db.execSQL(sql, new String[]{diary.getTitle(),diary.getContent(),diary.getCreatetime()});
}
//查找数据
public List<Diary> getAllDiaries(){
List<Diary> diaries=new ArrayList<Diary>();
SQLiteDatabase db=dbhelper.getReadableDatabase();
String sql="select * from diary";
Cursor cursor=db.rawQuery(sql, null);
while(cursor.moveToNext()){
//Integer id=cursor.getInt(cursor.getColumnIndex("id"));
String title=cursor.getString(cursor.getColumnIndex("title"));
String content=cursor.getString(cursor.getColumnIndex("content"));
String createtime=cursor.getString(cursor.getColumnIndex("createtime"));
Diary diary=new Diary(content, title, createtime);
diaries.add(diary);
}
return diaries;
}
//删除数据
public void deleteDiary(Integer id){
SQLiteDatabase db=dbhelper.getWritableDatabase();
String sql="delete from diary where id=?";
db.execSQL(sql,new Object[]{id});
}
//更新数据
public void updateDiary(Diary diary){
SQLiteDatabase db=dbhelper.getWritableDatabase();
String sql="update diary set title=?,content=?,createtime=? where id=?";
db.execSQL(sql, new Object[]{diary.getTitle(),diary.getContent(),diary.getCreatetime(),diary.getId()});
}
public long count() {
long count=0;
SQLiteDatabase db=dbhelper.getReadableDatabase();
Cursor cursor=db.rawQuery("select count(*) from diary ",null);
cursor.moveToFirst();
count=cursor.getLong(0);
return count;
}
//根据id查询数据
public Diary find(Integer id){
Diary diary = null;
SQLiteDatabase db=dbhelper.getReadableDatabase();
String sql="select * from diary where id=?";
Cursor cursor=db.rawQuery(sql, new String[]{id.toString()});
if(cursor.moveToFirst()){
Integer Id=cursor.getInt(cursor.getColumnIndex("id"));
String title=cursor.getString(cursor.getColumnIndex("title"));
String content=cursor.getString(cursor.getColumnIndex("content"));
String createtime=cursor.getString(cursor.getColumnIndex("createtime"));
diary=new Diary(content, title, createtime);
diary.setId(Id);
}
return diary;
}
public Diary findtitle(String title){
Diary diary = null;
SQLiteDatabase db=dbhelper.getReadableDatabase();
String sql="select * from diary where title=?";
Cursor cursor=db.rawQuery(sql, new String[]{title});
if(cursor.moveToFirst()){
Integer id=cursor.getInt(cursor.getColumnIndex("id"));
String Title=cursor.getString(cursor.getColumnIndex("title"));
String content=cursor.getString(cursor.getColumnIndex("content"));
String createtime=cursor.getString(cursor.getColumnIndex("createtime"));
diary=new Diary(content, Title, createtime);
diary.setId(id);
}
return diary;
}
}

4.进行单元测试的方法

package org.sql.sqlTest;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
import org.sql.Dao.DiaryDao;
import org.sql.entity.Diary;
import android.test.AndroidTestCase;
public class DiaryDaoTest extends AndroidTestCase {
//插入
public void testSave(){
DiaryDao diaryDao=new DiaryDao(getContext());
Diary diary=new Diary("我是破坏王", "配音谢娜", getcurrentTime());
diaryDao.save(diary);
diary=new Diary("迪斯尼乐园米老鼠与唐老鸭", "最爱", getcurrentTime());
diaryDao.save(diary);
diary=new Diary("致我们终将逝去的青春","《致青春》，导演赵薇",getcurrentTime());
diaryDao.save(diary);
diary=new Diary("5.26，是他们演唱的最后一场《MAMA》。虽说等新专等了很久，但还是忘不了那首曾经陪我们一年多的歌。到时候会不会有很多人忘记这首歌，原因是听了很久。我不敢保证。或许多年以后，许多行星饭就只听新歌，忘...... ", "鹿晗", getcurrentTime());
diaryDao.save(diary);
}
//查找
public void testgetAllDiaries(){
DiaryDao diaryDao=new DiaryDao(getContext());
List<Diary> diaries=diaryDao.getAllDiaries();
System.out.println(diaries);
}
public void testdelate(){
DiaryDao diaryDao=new DiaryDao(getContext());
diaryDao.deleteDiary(2);
}
public String getcurrentTime(){
SimpleDateFormat format= new SimpleDateFormat("yyyy年MM月dd日 hh:MM:ss");
return format.format(new Date());
}
//更新
public void testUpdate(){
DiaryDao diaryDao=new DiaryDao(getContext());
Diary diary=new Diary("我是米你", "迪斯尼乐园", getcurrentTime());
diary.setId(1);
diaryDao.updateDiary(diary);
}
//根据id查找数据测试
public void testFind(){
DiaryDao diaryDao=new DiaryDao(getContext());
Diary diary=diaryDao.find(1);
System.out.println(diary.getId());
}
public void testFindtitle(){
DiaryDao diaryDao=new DiaryDao(getContext());
Diary diary=diaryDao.findtitle("配音谢娜");
System.out.println(diary.getId());
}
}

5.各个页面中具体功能的实现

tabhost.addTab(buildTabSpec("TAB4", R.string.exit,
R.drawable.kuii, new Intent(MainActivity.this,
ExitActivity.class)));
}
private TabHost.TabSpec buildTabSpec(String tag, int realLable,
