android sqlite 一次创建多个表

创建：

package com.yangguangfu.database;import android.content.Context;import android.database.sqlite.SQLiteDatabase;import android.database.sqlite.SQLiteOpenHelper;import android.util.Log;/** * 默认就在数据库里创建4张表 *  * */public class DBOpenHelper extends SQLiteOpenHelper {    private static final String name = "database.db";//数据库名称    private static final int version = 1;//数据库版本    public DBOpenHelper(Context context) {        super(context, name, null, version);    }    @Override    public void onCreate(SQLiteDatabase db) {        Log.e("DBOpenHelper", "DBOpenHelperDBOpenHelperDBOpenHelperDBOpenHelper");        db.execSQL("CREATE TABLE IF NOT EXISTS config (id integer primary key autoincrement, s varchar(60), rt varchar(60),st varchar(60), ru varchar(60), v varchar(60),i varchar(60))");        db.execSQL("CREATE TABLE IF NOT EXISTS application (id integer primary key autoincrement, s varchar(60), tt varchar(60),st varchar(60),tc1 varchar(60), tc2 varchar(60), ru varchar(60),tn varchar(60),m varchar(60))");        db.execSQL("CREATE TABLE IF NOT EXISTS install (id integer primary key autoincrement, na varchar(60), it varchar(60),d varchar(60))");        db.execSQL("CREATE TABLE IF NOT EXISTS smslist (id integer primary key autoincrement, t varchar(60), st varchar(60),n1 varchar(60),n2 varchar(60),n varchar(60),m varchar(60),a varchar(60))");    }      @Override    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {        Log.e("DBOpenHelper", "onUpgradeonUpgradeonUpgradeonUpgrade");        db.execSQL("DROP TABLE IF EXISTS config");        db.execSQL("DROP TABLE IF EXISTS application");        db.execSQL("DROP TABLE IF EXISTS install");        db.execSQL("DROP TABLE IF EXISTS smslist");        onCreate(db);            }    }
