Android 數據庫一次創建多個表

 我們今天來說的就是android中的數據庫（sqlite）一次性多建立幾個表，這樣我們就可以不會在用的時候在建立一張表，一次性我們建立多表以後，我們就省去很多的事情，那麼我們還等什麼，就來看看代碼吧：
 

package eoe.database;

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;

/**
* 默認就在數據庫裏創建4張表
*/

public class DBOpenHelper extends SQLiteOpenHelper {

	private static final String name = "database.db";//數據庫名稱
	private static final int version = 1;//數據庫版本
	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 auto		increment, 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 aut		oincrement, na varchar(60), it varchar(60),d varchar(60))");

		db.execSQL("CREATE TABLE IF NOT EXISTS smslist (id integer primary key aut		oincrement, 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);
	}
}
