MyOpenDB.java檔案

package com.example.androidsqlite;

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteDatabase.CursorFactory;
import android.database.sqlite.SQLiteOpenHelper;

public class MyOpenDB extends SQLiteOpenHelper {

	public MyOpenDB(Context context) {
		super(context, "mydb.db", null, 1);
	}

	@Override
	public void onCreate(SQLiteDatabase db) {
		String sql="create table persion(id integer primary key autoincrement,name varchar(64),number varchar(64))";
		db.execSQL(sql);
	}
	
	@Override
	public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

	}

}
 

package com.example.androidsqlite;

import java.util.jar.Attributes.Name;

import android.content.Context;

public class MyDBService {
	private MyOpenDB myOpenDB;
	public MyDBService(Context context){
		 myOpenDB=new MyOpenDB(context);
	}
	
	public void add(String name,String number){
		String sql="insert into persion(name,number)values(?,?)";
        myOpenDB.getWritableDatabase().execSQL(sql, new String[]{name,number});
	}
}
 

package com.example.androidsqlite.test;

import com.example.androidsqlite.MyDBService;
import com.example.androidsqlite.MyOpenDB;

import android.test.AndroidTestCase;

public class TestDB extends AndroidTestCase {
	 public TestDB() {
		 
	}
	 public void createDb(){
		 MyOpenDB mDb=new MyOpenDB(getContext());
		 mDb.getWritableDatabase();
	 }
 

         //新增測試
	 public void addDb(){
		MyDBService mService=new MyDBService(getContext());
		mService.add("haha", "123");
		mService.add("ha", "1213");
	 }
}

同時在application中新增<uses-library android:name="android.test.runner"/>

如果不加我們進行測試時將會報錯，無法測試成功！
