GreenDao的簡單使用說明(二)單表的增,刪,改,查
阿新 • • 發佈:2019-01-25
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的使用者類也建立起來了,哪麼下面我們就來實現一下,對於這個單表的增,刪,改,查功能.
這裡說明一下,因為是做一個簡單的例子,所以這裡我對資料庫的操作,沒有做非同步處理.
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,先看程式碼.
通過程式碼上的註釋,我們也知道了,只所以要繼承自application,主要就是為了避免多次建立生成Session物件,提高效能.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物件的方法放到Application層這樣避免多次建立生成Session物件。 * 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; } }
第二步,建立一個操作類,把增,刪,改,查的方法,全寫進去.方便呼叫.程式碼如下
DbService.java
這個類就不多說了,大家一看就明白,很簡單,而且裡面也已經比較明確的給出了註解.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; /** * 使用者操作類 * 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() { } /** * 採用單例模式 * @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; } /** * 根據使用者id,取出使用者資訊 * @param id 使用者id * @return 使用者資訊 */ public Users loadNote(long id) { if(!TextUtils.isEmpty(id + "")) { return userDao.load(id); } return null; } /** * 取出所有資料 * @return 所有資料資訊 */ public List<Users> loadAllNote(){ return userDao.loadAll(); } /** * 生成按id倒排序的列表 * @return 倒排資料 */ public List<Users> loadAllNoteByOrder() { return userDao.queryBuilder().orderDesc(UsersDao.Properties.Id).list(); } /** * 根據查詢條件,返回資料列表 * @param where 條件 * @param params 引數 * @return 資料列表 */ public List<Users> queryNote(String where, String... params){ return userDao.queryRaw(where, params); } /** * 根據使用者資訊,外掛或修改資訊 * @param user 使用者資訊 * @return 外掛或修改的使用者id */ public long saveNote(Users user){ return userDao.insertOrReplace(user); } /** * 批量插入或修改使用者資訊 * @param list 使用者資訊列表 */ 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); } } }); } /** * 刪除所有資料 */ public void deleteAllNote(){ userDao.deleteAll(); } /** * 根據id,刪除資料 * @param id 使用者id */ public void deleteNote(long id){ userDao.deleteByKey(id); Log.i(TAG, "delete"); } /** * 根據使用者類,刪除資訊 * @param user 使用者資訊類 */ public void deleteNote(Users user){ userDao.delete(user); } }
第三步,設定佈局檔案
1,Toolbar的程式碼:
<?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,還要為其設定樣式,style.xml
<resources>
<style name="AppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- toolbar(actionbar)顏色 -->
<item name="colorPrimary">#4876FF</item>
<!-- 狀態列顏色 -->
<item name="colorPrimaryDark">#3A5FCD</item>
<!--toolbar文字的顏色-->
<item name="@android:textColorPrimary">@android:color/white</item>
<!-- 視窗的背景顏色 -->
<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佈局,這個佈局其實很簡單,就是一個Toolbar,Toolbar上選單有一個新增的按鈕,而且下面是一個listView用來顯示使用者,點選新增按鈕,彈出一個對話方塊,顯示你要新增的項,填寫完後,儲存,新加的資料就會在listView中顯示出來.點選列表項,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檔案
<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選單欄的佈局檔案,menu_one_table.xml.主要就是添加了一個新增的按鈕
<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="新增"
app:showAsAction="never" />
</menu>
下面是listView列表顯示,哪麼我們先為這個列表設定一個item的佈局.程式碼比較簡單:'
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;
/**
* 使用者資訊顯示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.我們來完成點選新增時,彈出的對話方塊,這裡採用的DialogFragment
先看佈局檔案fragment_onetable_dialog.xml

這裡就不多說了,一是程式碼比較簡單,二是裡面的註釋也比較清楚,大家一眼就明白了.
下面就是對點選item項的時候,彈出的對框進行設計,先看佈局,就兩個textView
fragment_onetable_itemdialog.xml
