我已经阅读了 Failed to change locale for db '/data/data/my.easymedi.controller/databases/EasyMediInfo.db' to 'en_US' 的解决方案但这对我没有帮助。我仍然有同样的错误。

这些是我的 DBHelper 类。你能调查一下并帮助我吗?

}

它以前工作得很好,但我对数据库进行了一些升级,然后它就停止工作了。我想这是这个错误的根源,但我不确定。

提前致谢!

根据您的要求:

我在我的 MainActivity 类中调用了 createDataBase 方法,如下所示:

package com.example.mgr;

import java.io.IOException;
import java.util.ArrayList;

import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.view.Gravity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Adapter;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity implements OnClickListener {

SharedPreferences preferences;
TextView tv;
Adapter adapter;
SQLiteDatabase as;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button infDlaStudButton = (Button) findViewById(R.id.infDlaStud);
Button infDlaKandButton = (Button) findViewById(R.id.infDlaKand);
preferences = PreferenceManager.getDefaultSharedPreferences(this);
DBHelper myDbHelper = new DBHelper(this);
infDlaStudButton.setOnClickListener(this);
infDlaKandButton.setOnClickListener(this);

infDlaKandButton.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
ble();

}

});

infDlaStudButton.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
ble();
}
});

try {
myDbHelper.createDataBase();
System.out.println("Stworzyłam bazę danych");

} catch (IOException ioe) {

throw new Error("nie moge to create database");

}
System.out.println("bede otwierdal baze danych w glowej metodzie");

myDbHelper.openDataBase();

}

void ble() {
Intent intent = new Intent();
intent.setClass(MainActivity.this, SecondActivity.class);
startActivity(intent);
}

@Override
public void onClick(View arg0) {
Toast.makeText(this, "ble", Toast.LENGTH_LONG).show();
// TODO Auto-generated method stub

}

}

是的,android_metadata 表存在于数据库中并且具有“en_US”值。

我已经创建了新的、非常简单的数据库Drzewo.db。当此表只有 2 个表时:andoid_metadata 和另一个表 (Przyjeci) 那么一切正常!但是后来我添加了新表并尝试进行升级,但我遇到了同样的错误。

有我的日志(来自这个新数据库):

我在 eclipse juno + Android 4.2.2

上工作

最佳答案

我无法将所有这些代码都放在评论中,所以请试试这些:请记住,我并没有添加所有的样板文件……好吗?

更改 checkDb 方法:

private boolean checkDataBase(){
File dbFile = new File( DATABASE_PATH, DATABASE_NAME );
return dbFile.exists();
}

更改 createDb 方法:

public void createDataBase() {
if(checkDb()){
//do nothing
} else {
copyDatabase();
}
}

更改 copyDatabase() 方法:

private void copyDataBase(){
getReadableDatabase();

//add the rest of your current implementation

}

将构造函数的可访问性更改为私有(private)并添加这些方法:

private DBHelper mInstance = null;
public static DBHelper getInstance(Context context) {
if(mInstance == null)
mInstance = new DBHelper(context)
return mInstance;
}
//remove the old openDatabase method
public SQLiteDatabase openDatabase() {
return getReadableDatabase(); //or you can use getWritableDatabase();
}
