bu

Bu 一个Android开发的生产库，主要有以下几个部分构成：

一、UI组件

1.Application--BuApplication 示例： 2.Activity --BuActivity 示例： 3.Fragment --BuFragment

二、数据库组件

1.DataBase --BuInfoDB,BuAuthorityProvider 示例： /** *

• the provider's stuff : BuAuthority.AUTHORITY.mzj

• @Des org.bu.android.providers.mzj.*

• @author jxs

• @time 2014-9-15 下午11:17:20 */ public abstract class ATProvider extends BuAuthorityProvider {

  @Override protected String getAuthority() { return "mzj_at"; }

  @Override protected String getNullColumnHack() { return BuTable._ID; }

  @Override protected String getItemId() { return BuTable._ID; }

} public class UserInfoProvider extends ATProvider {

@Override
protected String getTableName() {
	return UserInfoHolder.Table.TABLE_NAME;
}

@Override
protected String getNullColumnHack() {
	return UserInfoHolder.Table._ID;
}

@Override
protected String getItemId() {
	return UserInfoHolder.Table._ID;
}

@Override
public SQLiteOpenHelper getSQLiteOpenHelper() {
	return new UserInfoDB(getContext());
}

}

创建数据库 UserInfoHolder 方法creater(DB); public synchronized void creater(SQLiteDatabase db) { creater(db, new Table() {

		@Override
		public String getTable() {
			return TABLE_NAME;
		}

		@Override
		public Map<String, String> colMaps() {

			Map<String, String> cols = new LinkedHashMap<String, String>();

			cols.put(USER_ID, "varchar(30)");
			cols.put(USER_NAME, "varchar(30)");
			cols.put(USER_PWD, "varchar(30)");
			cols.put(ACCESS_TOKEN, "varchar(30)");
			cols.put(REFRESH_TOKEN, "varchar(30)");
			cols.put(EXPIRES_IN, "varchar(30)");
			cols.put(CREATE_TIME, "varchar(30)");
			cols.put(UPDATE_TIME, "varchar(30)");
			return cols;
		}
	});
}

public class UserInfoDB extends BuInfoDB {

public UserInfoDB(Context context) {
	super(context, new DB() {

		@Override
		public String dbName() {
			return "mzj_user_info_db";
		}

		@Override
		public int dbVersion() {
			return 1;
		}

		@Override
		public void onCreate(SQLiteDatabase db) {
			UserInfoHolder.getInstance().creater(db);
		}

		@Override
		public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
			db.execSQL("DROP TABLE IF EXISTS " + UserInfoHolder.Table.TABLE_NAME);
			onCreate(db);
		}

	});
}

}

三、网络通信组件

Http      --BuHttp

四、Widget 组件
