Question

我需要获取SQLite数据库的路径才能打开它以查询语法：

rDb = SQLiteDatabase.openDatabase(mPath, null, 0);

其中mPath将是数据库的路径，rDb是数据库文件。

代码适用于此查询语句：

public ArrayList<String> getList(){ //List Query

    String FOOD_TYPE = "";
    String LOCATION = "";
    String TAKEREST = "";
    ArrayList<String> NameList = new ArrayList<String>();
    String[] columns = new String[]{COLUMN_ROWID, COLUMN_NAME, COLUMN_TELEPHONE, COLUMN_EMAIL, COLUMN_MENUURL, COLUMN_WEBSITE, COLUMN_MOBILE, COLUMN_CUISINE, COLUMN_LOCATION, COLUMN_TAKEREST};
    rDb = SQLiteDatabase.openDatabase(mPath, null, 0);
    Cursor list = rDb.query(DATABASE_TABLE, columns,"food_type = ? AND location = ? AND Restaurant_or_takeaway = ?", new String[] {FOOD_TYPE, LOCATION, TAKEREST}, null, null, null);

    for(list.moveToFirst(); !list.isAfterLast(); list.moveToNext()) {
        Log.d("in loop", "msg");
        NameList.add(list.getString(list.getColumnIndex(COLUMN_NAME)));
    }
    rDb.close();
    return NameList;
}

关于如何解决这个问题的任何想法？

您可以使用[databaseList]( http://developer.android.com/reference/android/content/Context.html)

从上下文中获取数据库列表
