通過上一篇文章,我們已經把GreenDao框架架起來了,而且三個基礎操作類和Users的用戶類也建立起來了,哪么下面我們就來實現一下,對于這個單表的增,刪,改,查功能.

這里說明一下,因為是做一個簡單的例子,所以這里我對數據庫的操作,沒有做異步處理.

第一步,我們要先來寫一個類BaseApplication.java,此類是用來取得GreenDao中的DaoMaster和DaoSession的,先看代碼.

package com.example.cg.greendaolearn.db;

import android.app.Application;
import android.content.Context;

import com.example.cg.greendaolearn.THDevOpenHelper;
import com.guangda.dao.DaoMaster;
import com.guangda.dao.DaoSession;

/**
 * 官方推薦將取得DaoMaster對象的方法放到Application層這樣避免多次創建生成Session對象。
 * Created by cg on 2015/12/29.
 */
public class BaseApplication extends Application {
    private static BaseApplication mInstance;
    private static DaoMaster daoMaster;
    private static DaoSession daoSession;

    @Override
    public void onCreate() {
        super.onCreate();
        if(mInstance == null)
            mInstance = this;
    }

    /**
     * 取得DaoMaster
     *
     * @param context        上下文
     * @return               DaoMaster
     */
    public static DaoMaster getDaoMaster(Context context) {
        if (daoMaster == null) {
            DaoMaster.OpenHelper helper = new THDevOpenHelper(context,"myDb",null);
            daoMaster = new DaoMaster(helper.getWritableDatabase());
        }
        return daoMaster;
    }

    /**
     * 取得DaoSession
     *
     * @param context        上下文
     * @return               DaoSession
     */
    public static DaoSession getDaoSession(Context context) {
        if (daoSession == null) {
            if (daoMaster == null) {
                daoMaster = getDaoMaster(context);
            }
            daoSession = daoMaster.newSession();
        }
        return daoSession;
    }
}

通過代碼上的注釋,我們也知道了,只所以要繼承自application,主要就是為了避免多次創建生成Session對象,提高性能.

第二步,建立一個操作類,把增,刪,改,查的方法,全寫進去.方便調用.代碼如下

DbService.java

package com.example.cg.greendaolearn.db;

import android.content.Context;
import android.text.TextUtils;
import android.util.Log;

import com.guangda.dao.DaoSession;
import com.guangda.dao.UsersDao;

import java.util.List;

import greendao.Users;

/**
 * 用戶操作類
 * Created by cg on 2015/12/29.
 */
public class DbService {
    private static final String TAG = DbService.class.getSimpleName();
    private static DbService instance;
    private static Context appContext;
    private DaoSession mDaoSession;
    private UsersDao userDao;


    private DbService() {
    }

    /**
     * 采用單例模式
     * @param context     上下文
     * @return            dbservice
     */
    public static DbService getInstance(Context context) {
        if (instance == null) {
            instance = new DbService();
            if (appContext == null){
                appContext = context.getApplicationContext();
            }
            instance.mDaoSession = BaseApplication.getDaoSession(context);
            instance.userDao = instance.mDaoSession.getUsersDao();
        }
        return instance;
    }

    /**
     * 根據用戶id,取出用戶信息
     * @param id           用戶id
     * @return             用戶信息
     */
    public Users loadNote(long id) {
        if(!TextUtils.isEmpty(id + "")) {
            return userDao.load(id);
        }
        return  null;
    }

    /**
     * 取出所有數據
     * @return      所有數據信息
     */
    public List<Users> loadAllNote(){
        return userDao.loadAll();
    }

    /**
     * 生成按id倒排序的列表
     * @return      倒排數據
     */
    public List<Users> loadAllNoteByOrder()
    {
        return userDao.queryBuilder().orderDesc(UsersDao.Properties.Id).list();
    }

    /**
     * 根據查詢條件,返回數據列表
     * @param where        條件
     * @param params       參數
     * @return             數據列表
     */
    public List<Users> queryNote(String where, String... params){
        return userDao.queryRaw(where, params);
    }


    /**
     * 根據用戶信息,插件或修改信息
     * @param user              用戶信息
     * @return 插件或修改的用戶id
     */
    public long saveNote(Users user){
        return userDao.insertOrReplace(user);
    }


    /**
     * 批量插入或修改用戶信息
     * @param list      用戶信息列表
     */
    public void saveNoteLists(final List<Users> list){
        if(list == null || list.isEmpty()){
            return;
        }
        userDao.getSession().runInTx(new Runnable() {
            @Override
            public void run() {
                for(int i=0; i<list.size(); i++){
                    Users user = list.get(i);
                    userDao.insertOrReplace(user);
                }
            }
        });

    }

    /**
     * 刪除所有數據
     */
    public void deleteAllNote(){
        userDao.deleteAll();
    }

    /**
     * 根據id,刪除數據
     * @param id      用戶id
     */
    public void deleteNote(long id){
        userDao.deleteByKey(id);
        Log.i(TAG, "delete");
    }

    /**
     * 根據用戶類,刪除信息
     * @param user    用戶信息類
     */
    public void deleteNote(Users user){
        userDao.delete(user);
    }
}

這個類就不多說了,大家一看就明白,很簡單,而且里面也已經比較明確的給出了注解.

第三步,設置布局文件

1,Toolbar的代碼:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    android:minHeight="?attr/actionBarSize"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    app:theme="@style/ThemeOverlay.AppCompat.ActionBar">

</android.support.v7.widget.Toolbar>

當然了,你要是想使用toolbar,還要為其設置樣式,style.xml

<resources>

    <style name="AppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar">

        <!-- toolbar（actionbar）顏色 -->
        <item name="colorPrimary">#4876FF</item>
        <!-- 狀態欄顏色 -->
        <item name="colorPrimaryDark">#3A5FCD</item>
        <!--toolbar文字的顏色-->
        <item name="@android:textColorPrimary">@android:color/white</item>
        <!-- 窗口的背景顏色 -->
        <item name="android:windowBackground">@android:color/white</item>
        <!-- SearchView -->
        <item name="searchViewStyle">@style/MySearchViewStyle</item>

        <item name="actionMenuTextColor">#ffffff</item>

    </style>

    <style name="AppTheme" parent="@style/AppBaseTheme">
        <item name="android:windowIsTranslucent">true</item>
    </style>

    <style name="MySearchViewStyle" parent="Widget.AppCompat.SearchView"></style>

    <style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
        <item name="spinBars">true</item>
        <item name="color">@android:color/white</item>
    </style>

</resources>

現在來看一下頁面主布局,這個布局其實很簡單,就是一個Toolbar,Toolbar上菜單有一個添加的按鈕,而且下面是一個listView用來顯示用戶,點擊添加按鈕,彈出一個對話框,顯示你要添加的項,填寫完后,保存,新加的數據就會在listView中顯示出來.點擊列表項,會彈出對框,上面有刪除與修改的選項,可以對此項進行刪除與修改,

好,先來看一下activity_one_table.xml文件

<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"
    tools:context="com.example.cg.greendaolearn.oneTableActivity"
    android:orientation="vertical">
    <include
        layout="@layout/toolbar" />

    <ListView
        android:id="@+id/lv_oneTable"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />

</LinearLayout>

接下來,看一下,toolbar菜單欄的布局文件,menu_one_table.xml.主要就是添加了一個添加的按鈕

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.example.cg.greendaolearn.oneTableActivity">

    <item android:id="@+id/menu_onetable_add"
        android:title="添加"
        app:showAsAction="never" />
</menu>

下面是listView列表顯示,哪么我們先為這個列表設置一個item的布局.代碼比較簡單:'

activity_onetable_lv_item.xml

<?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:background="@color/coral">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1">
            <TextView
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:gravity="center"
                android:text="姓名:"
                android:textColor="@color/white"
                android:padding="5dp"/>
            <TextView
                android:id="@+id/txt_onetable_uName"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:textColor="@color/white"
                android:padding="5dp"/>
        </LinearLayout>
        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1">
            <TextView
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:gravity="center"
                android:text="性別:"
                android:textColor="@color/white"
                android:padding="5dp"/>
            <TextView
                android:id="@+id/txt_onetable_uSex"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:textColor="@color/white"
                android:padding="5dp"/>
        </LinearLayout>
    </LinearLayout>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="5dp">
        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1">
            <TextView
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:gravity="center"
                android:text="年紀:"
                android:textColor="@color/white"
                android:padding="5dp"/>
            <TextView
                android:id="@+id/txt_onetable_age"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:textColor="@color/white"
                android:padding="5dp"/>
        </LinearLayout>
        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1">
            <TextView
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:gravity="center"
                android:text="電話:"
                android:textColor="@color/white"
                android:padding="5dp"/>
            <TextView
                android:id="@+id/txt_onetable_tel"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:textColor="@color/white"
                android:padding="5dp"/>
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

為再為它設計一個Adapter

onetable_adapter.java

package com.example.cg.greendaolearn.adpater;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

import com.example.cg.greendaolearn.R;

import java.util.List;

import greendao.Users;

/**
 * 用戶信息顯示Adapter
 * Created by cg on 2015/12/29.
 */
public class onetable_adapter extends BaseAdapter {

    private LayoutInflater inflater;
    private List<Users> list_user;

    public onetable_adapter(Context context,List<Users> list_user) {
        this.inflater = LayoutInflater.from(context);
        this.list_user = list_user;
    }

    @Override
    public int getCount() {
        return list_user.size();
    }

    @Override
    public Object getItem(int position) {
        return list_user.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        userInfo uInfo;
        if(convertView==null)
        {
            uInfo = new userInfo();
            convertView = inflater.inflate(R.layout.activity_onetable_lv_item,null);
            uInfo.uAge = (TextView)convertView.findViewById(R.id.txt_onetable_age);
            uInfo.uName = (TextView)convertView.findViewById(R.id.txt_onetable_uName);
            uInfo.uSex = (TextView)convertView.findViewById(R.id.txt_onetable_uSex);
            uInfo.uTel = (TextView)convertView.findViewById(R.id.txt_onetable_tel);

            convertView.setTag(uInfo);
        }else
        {
            uInfo = (userInfo)convertView.getTag();
        }

        uInfo.uSex.setText(list_user.get(position).getUSex());
        uInfo.uTel.setText(list_user.get(position).getUTelphone());
        uInfo.uName.setText(list_user.get(position).getUName());
        uInfo.uAge.setText(list_user.get(position).getUAge());


        return convertView;
    }

    public class userInfo
    {
        TextView uName;
        TextView uSex;
        TextView uAge;
        TextView uTel;
    }
}

listVIew搞定了.我們來完成點擊添加時,彈出的對話框,這里采用的DialogFragment

先看布局文件fragment_onetable_dialog.xml

<?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent"

                    android:layout_weight="1"
                    android:textColor="@color/black"/>

        return builder.create();

這里就不多說了,一是代碼比較簡單,二是里面的注釋也比較清楚,大家一眼就明白了.

下面就是對點擊item項的時候,彈出的對框進行設計,先看布局,就兩個textView

fragment_onetable_itemdialog.xml

<?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">

    <TextView
        android:id="@+id/txt_onetable_update"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="修改"
        android:padding="10dp"
        android:gravity="center"/>
    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@color/gray"/>
    <TextView
        android:id="@+id/txt_onetable_delete"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="刪除"
        android:padding="10dp"
        android:gravity="center"/>
</LinearLayout>

代碼:oneTableItemDialogFragment.java

package com.example.cg.greendaolearn;

    private TextView txt_onetable_update;
    private TextView txt_onetable_delete;

    public interface EditUserOnClickListener

        super.onViewCreated(view, savedInstanceState);

                listener.onEditUserOnClick(id,postion,0);
            }
        });
    }
}

OK了,現在我們來看一下,主程序的代碼:oneTableActivity.java
