java – 无法将db’/data/data/my.easymedi.controller/databases/EasyMediInfo.db’的区域设置更改为“en_US”

分类：Java作者：编程之家
在我的 Android应用程序中有一个预定义的数据库,它位于assets文件夹中.我创建了一个表的android_Metadata,带有一个名为locale的列,并有一个记录en_US.在我的应用程序中,用户应该输入他/她的详细信息,然后点击保存按钮.当点击保存按钮时,我收到以下错误.

这是我的代码段保存按钮.

case R.id.btnSave:
        personName = etName.getText().toString();
        date_of_birth = tvdob.getText().toString();
        age = tvAge.getText().toString();

        int selected_rb_ID = genderGrp.getCheckedRadioButtonId();   
        RadioButton rb = (RadioButton) findViewById(selected_rb_ID);
        gender = rb.getText().toString();
        bloodGrp = spiBloodGrp.getSelectedItem().toString();

        Person person = new Person();
        person.setName(personName);
        person.setDate_of_birth(date_of_birth);
        person.setAge(age);
        person.setGender(gender);
        person.setBloodGrp(bloodGrp);

        ContentValues values = new ContentValues();
        values.put(COLUMN_PERSON_NAME,person.getName());
        values.put(COLUMN_dob,person.getDate_of_birth());
        values.put(COLUMN_AGE,person.getAge());
        values.put(COLUMN_GENDER,person.getGender());
        values.put(COLUMN_BLOODGRP,person.getBloodGrp());

        DBHelper dbHelper = new DBHelper(this);
        dbHelper.createDataBase();
        dbHelper.openDataBase();
        if(dbHelper.insertIntoDatabase("EMPerson",values)){
            Toast.makeText(getApplicationContext(),"Data has been saved successfully",Toast.LENGTH_SHORT).show();
        }else{
            Toast.makeText(getApplicationContext(),"Oops ! Try again",Toast.LENGTH_SHORT).show();
        }
        dbHelper.closeDatabase();

        break;

在我的主要活动中,我通过调用这个代码段创建了数据库.

final DBHelper helper = new DBHelper(this);
helper.createDataBase();

如果任何人能够如此善于解释这个错误是什么,我将是非常有义务的.

Thanx提前

解决方法

您的copyDataBase()函数从资产文件夹中复制数据库(EasyMediInfo.db).而且看起来数据库是使用与’en_US’不同的语言环境创建的.

编辑

尝试更改：

myDatabase = sqliteDatabase.openDatabase(myPath,sqliteDatabase.OPEN_READWRITE);

至：

myDatabase = sqliteDatabase.openDatabase(myPath,sqliteDatabase.NO_LOCALIZED_COLLATORS | sqliteDatabase.OPEN_READWRITE);
