提高在Android中使用xml字符串的数据库创建速度

Question

我正在使用单个数据库创建一个针对API 17的应用程序，该数据库在完成时将具有300-700行非常重的文本。我最初选择以编程方式创建我的数据库，将要添加到数据库的文本保存为res / values字符串文件中的xml文件中的字符串。

我已经阅读了有关使用DatabaseUtils.InsertHelper（）的对话，我知道这种对话已被弃用，而SQLite Statement却不知道如何在填充数据库时以这种方式更改当前代码以提高性能。

我与数据库相关的主要活动代码如下：

    public class MainActivity extends FragmentActivity 
    implements //implementations for various fragments

public LawDbAdapter dbHelper;
LawDbAdapter db;

public SimpleCursorAdapter cursorAdapter;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {

    //code for creating the fragment and inflating the view

    openDatabase();
    }

private void openDatabase() {
    db = new LawDbAdapter(this);

    db.open();
    //Clean all data
    db.deleteAllEntries();
    //Add some data
    db.insertSomeEntrys();  
}

private void showInfoNamedCursor(String namedCursor) {
    Cursor cursor = db.fetchEntriesByName(namedCursor);
    String a;
    String b;
    String c;
    String d;
    String e;
    String f;

    a = cursor.getString(cursor.getColumnIndexOrThrow("aaa"));
    b = cursor.getString(cursor.getColumnIndexOrThrow("bbb"));
    c = cursor.getString(cursor.getColumnIndexOrThrow("ccc"));
    d = cursor.getString(cursor.getColumnIndexOrThrow("ddd"));
    e = cursor.getString(cursor.getColumnIndexOrThrow("eee"));
    f = cursor.getString(cursor.getColumnIndexOrThrow("fff"));

    onLawSelected(0,  name,  section,  act,  definition,  arrest,  detain); 
}

我的数据库适配器代码如下：

    public class LawDbAdapter {

//static variables for the ROW NAMES of the Law table


//TAG for Log prints
private static final String TAG = "LawDbAdapter";

//db and db helpers
private static DatabaseHelper mDbHelper;
private SQLiteDatabase mDb;

//Database and table name/version
private static final String DATABASE_NAME = "Legislation";
private static final String SQLITE_TABLE = "Law";
private static final int DATABASE_VERSION = 1;

//reference to the current context
private final Context mCtx;

//String to create the database if it does not already exist
private static final String DATABASE_CREATE =
    "CREATE TABLE if not exists " + SQLITE_TABLE + " (" +
    KEY_ROWID + " integer PRIMARY KEY autoincrement," +
    KEY_SECTION + "," +
    KEY_NAME + "," +
    KEY_DEFINITION + "," +
    KEY_ACT + "," +
    KEY_ARREST + ","+
    KEY_KEYWORDS + ","+
    KEY_GROUP + "," +
    KEY_DETAINABLE +
    ");"
    ;

private static class DatabaseHelper extends SQLiteOpenHelper {

    public static DatabaseHelper getInstance(Context ctx) {

        // Use the application context, which will ensure that you 
        // don't accidentally leak an Activity's context.
        // See this article for more information: http://bit.ly/6LRzfx
        if (mDbHelper == null) {
            mDbHelper = new DatabaseHelper(ctx.getApplicationContext());
            Log.d("DBADAPTER", "NEW DATABASE HELPER OBJECT CREATED");

        }
        return mDbHelper;
    } 


    private DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }


    @Override
    public void onCreate(SQLiteDatabase db) {
        Log.w(TAG, DATABASE_CREATE);
        //create database
        db.execSQL(DATABASE_CREATE);
        System.out.println("onCreate()  DATABASE CREATED " + db.toString());


    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        Log.w(TAG, "Upgrading database from version " + oldVersion + " to "
                + newVersion + ", which will destroy all old data");
        //drop old table
        db.execSQL("DROP TABLE IF EXISTS " + SQLITE_TABLE);
        //call on create ot create new table
        onCreate(db);
    }
}

public LawDbAdapter(Context ctx) {
    //reference current context
    this.mCtx = ctx;
}

public LawDbAdapter open() throws SQLException {
    DatabaseHelper.getInstance(mCtx);
    mDb = mDbHelper.getWritableDatabase();
    System.out.println("LawDb Adapter opne()   DATABASE ADAPTER " + this.toString());
    return this;
}

public void close() {
    if (mDbHelper != null) {
        mDbHelper.close();
    }
}

Answer 1

  

我最初选择以编程方式创建我的数据库，将要添加到数据库的文本保存为res / values strings files中找到的xml文件中的字符串

除非您使用字符串资源来允许翻译，否则通过发送预先打包的SQLite数据库perhaps using SQLiteAssetHelper可能会更好地为您提供服务。

  

我已经阅读了有关使用DatabaseUtils.InsertHelper（）的对话，我知道这种对话已被弃用，而SQLite Statement却不知道如何在填充数据库时以这种方式更改当前代码以提高性能。

我怀疑这些都是你的问题。您的问题是您没有使用交易。修改insertSomeEntrys()以使用交易：

public void insertSomeEntrys() {
  try {
    mDb.beginTransaction();

    // insert all of your current code here

    mDb.setTransactionSuccessful();
  }
  finally {
     mDb.endTransaction();
  }
}
