Android 数据库一次创建多个表

 我们今天来说的就是android中的数据库（sqlite）一次性多建立几个表，这样我们就可以不会在用的时候在建立一张表，一次性我们建立多表以后，我们就省去很多的事情，那么我们还等什么，就来看看代码吧：
 

package eoe.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);}@Overridepublic 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))");}@Overridepublic 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);}}
