简单的Android Sqlite 使用：

package com.pdsu.db_test;

import java.sql.Date;

import android.app.Activity;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.widget.Toast;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SQLiteDatabase db = openOrCreateDatabase("test.db", MODE_PRIVATE, null);
// db.execSQL("CREATE TABLE IF NOT EXISTS person (number INT(11),name
// VARCHAR(255),birthday DATE);");

db.execSQL("insert into person (number,name,birthday) values(12,\"zhangqing\",\"20150803\");");

Cursor cursor = db.query("person", null, null, null, null, null, null);
cursor.moveToFirst();
while (cursor.moveToNext()) {
int number = cursor.getInt(0);
String name = cursor.getString(1);
String date = cursor.getString(2);
Toast.makeText(this, number + ">>" + name + ">>" + date, 0).show();
}
Toast.makeText(this, cursor.toString(), Toast.LENGTH_SHORT).show();
}
}
