一佛舱、配置

1.修改gradle文件夾下的gradle-wrapper.properties修改為：

distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip

2、在工程的buildgradle中導(dǎo)入

dependencies {

classpath 'org.greenrobot:greendao-gradle-plugin:3.2.2'

}

3、在項目的buildgradle中導(dǎo)入

//導(dǎo)入插件

apply plugin: 'com.android.application'

apply plugin: 'org.greenrobot.greendao'

//在dependencies中添加如下代碼

dependencies {

compile 'org.greenrobot:greendao:3.2.2'

}

二眶痰、工具類

public classDaosingleton {private staticDaosingletondaosingleton;privateDaosingleton() {? ? }publicBookDao getdao(Context context) {? ? ? ? DaoMaster.DevOpenHelper devOpenHelper =newDaoMaster.DevOpenHelper(context,"students.db",null);? ? ? ? DaoMaster daoMaster =newDaoMaster(devOpenHelper.getReadableDb());? ? ? ? DaoSession daoSession = daoMaster.newSession();? ? ? ? BookDao studentsDao = daoSession.getBookDao();returnstudentsDao;? ? }public staticDaosingleton getDaosingleton() {if(daosingleton==null) {synchronized(Daosingleton.class) {if(daosingleton==null) {daosingleton=newDaosingleton();? ? ? ? ? ? ? ? }? ? ? ? ? ? }? ? ? ? }returndaosingleton;? ? }}

三、簡單使用

public classMain2ActivityextendsAppCompatActivityimplementsView.OnClickListener, AdapterView.OnItemLongClickListener {privateButtoninsert;privateProgressBarbar;privateListViewlistview;privateBookDaogetdao;privateMyAdaptermyAdapter;privateListlist=null;privatePopupWindowwindow;@Overrideprotected voidonCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);? ? ? ? setContentView(R.layout.activity_main2);getdao= Daosingleton.getDaosingleton().getdao(Main2Activity.this);? ? ? ? initView();? ? ? ? initData();? ? }private voidinitPro(finalList list1) {? ? ? ? Handler handler=newHandler();? ? ? ? handler.postDelayed(newRunnable() {@Overridepublic voidrun() {? ? ? ? ? ? ? ? runOnUiThread(newRunnable() {@Overridepublic voidrun() {bar.setVisibility(View.GONE);myAdapter.notifys(list1);? ? ? ? ? ? ? ? ? ? }? ? ? ? ? ? ? ? });? ? ? ? ? ? }? ? ? ? },2000);? ? }private voidinitView() {insert= (Button) findViewById(R.id.insert);bar= (ProgressBar) findViewById(R.id.bar);listview= (ListView) findViewById(R.id.listview);/* initPro();*/insert.setOnClickListener(this);? ? }private voidinitData() {list=getdao.queryBuilder().build().list();myAdapter=newMyAdapter(Main2Activity.this,list);listview.setAdapter(myAdapter);myAdapter.notifys(list);listview.setOnItemLongClickListener(this);? ? }@Overridepublic voidonClick(View v) {switch(v.getId()) {caseR.id.insert:? ? ? ? ? ? ? ? Intent intent=newIntent(Main2Activity.this,Main3Activity.class);? ? ? ? ? ? ? ? startActivity(intent);break;? ? ? ? }? ? }@Overridepublic booleanonItemLongClick(AdapterView adapterView, View view,final inti,longl) {? ? ? ? View view1=View.inflate(Main2Activity.this,R.layout.view,null);window=newPopupWindow(view1,300,300);window.showAsDropDown(listview.getChildAt(i));window.setBackgroundDrawable(newColorDrawable(0));window.setOutsideTouchable(true);? ? ? ? Button updata=(Button) view1.findViewById(R.id.updata);? ? ? ?

Book book =list.get(i);myAdapter.de(book);getdao.delete(book);myAdapter.notifys(list);window.dismiss();? ? ? ? ? ? }? ? ? ? });? ? ? ? updata.setOnClickListener(newView.OnClickListener() {@Overridepublic voidonClick(View view) {? ? ? ? ? ? ? ?
