With the enhancement of the computing ability of terminal equipment, users need more and more interactive effect when they use the map.For example, in today's very hot indoor navigation, in order to get a good user experience, it is necessary to change the color of the store when a user clicks on a store. This requires that vector layers be superimposed.How can I overlay a vector layer on top of a tile

Balance between vector, map, and list From: [http://www.codingnow.com/2004/board/view.php? Paster= 776] I want to create a data structure to store data in an orderly manner for convenient search, and the efficiency of data insertion is not too low. When the data is almost unchanged, vector is the best solution. We only need to put the data in. After sort

[i], index)); Strvec.push_back (index); Index + =1; }Else{Strvec.push_back (strm[str[i]); } }returnStrvec;}Here, a map is used to hold the key-value pairs for each character and index, and the index is represented by index, starting at 0.The final sequence of numbers is saved with vectors.Loops through the entire string, looking for a character in the map each time, if not found, adds it and t

search speed is relatively high. 5.The key of a map must be unique. 6.The stack adapter must be used with other containers. The default internal container in STL is deque. First, only one exit is available, and traversal is not allowed. 7.Queue is a restricted deque. It is easier to use a list for internal containers. First-in-first-out, traversal not allowed. Below are some guidelines for selecting the sequence container type 1. If we need to random

box:For the choice of coordinate system, depends on your data, if it is a GPS device measurement points, you can directly select 4326, so that the map coordinates can be used directly. If you get coordinates from a network map such as a gold map, you select the appropriate projected coordinate system, or the feature location you create is incorrect.2. Field defi

Maps are associative, andvectors,lists,anddeque are sequential in type. Map: Underlying mechanism rb-tree(red-black tree), automatic ordering of elements, key-value pairs. Vector: operates in a similar way to array, with dynamic space growth. is a continuous space that supports random access. Advantages:? Memory is dynamically growing and does not require a specified memory size.? Support for random access

1. Vector # Include Execution result: 0 1 2 3 5 7 9 When deleting an element in a vector, the following elements are moved forward by one place, so the original iterators are invalid. After deleting the first number 4 greater than 3: 0 1 2 3 5 6 7 8 9 ---> But now the iterator points to 5, ITER ++ points to 6 again, and 5 is missing... As a result, 5, 7, and 9 are not deleted. Method of modification: In lo

When vector loops are removed, erase (IT) returns the address of the next iterator, and the insurance practice is to assign it to the IT it= erase (IT) This is caused by the vector's internal mechanism, so pay special attention to whether the iterator will fail when the vector is erase! Map can be directly erase (it++); Neither

using animatedvectordrawable, animatedvectordrawable resources are placed in the DRAWABLE-V21 directory, and the drawable provides a Animatedvectordrawable the same name as the resource to be used in versions prior to 5.0, in this XML file you can use a selector to replace the animation.Note that sometimes for brevity it may be possible to put vectordrawable under the Pathdata in String.xml, and then refer to it under vectordrawable, such as:path android:name="right_arm" android:fillColor

1, vector (continuous space storage, you can use the [] operator) can quickly access random elements, quickly inserted at the end of the element, but in the middle of the sequence randomly inserted , delete elements are slow. Also, if there is not enough space at the outset, there is a process to reallocate more space.2, deque (small piece of continuous, small sheet connected with the linked list, in fact there is a

Sequent container: (vector)Erase not only invalidates all iterators pointing to the deleted element, but also invalidates all iterators after the deleted element. Therefore, the erase (ITER ++) method cannot be used, however, the returned value of erase is the next effective iterator. The correct method is ::For (iter = C. Begin (); iter! = C. End ();) Iter = C. Erase (ITER ); Associated container: (MAP)The

Formally, there is n lights and m switches, each switch controls one or more lights, i.e. pressing that switch flips the Status of those lights (On->off, Off->on).Initially, all the lights is on. Your task is to count the number of ways to turn off, the lights by pressing some c

Question: uva11991easy problem from rujia Liu? (MAP + vector) Give you n numbers, which may be repeated. Then, in m queries, ask the subscript of the k V. If such a number does not exist, output 0. Solution: map each number and subscript for one-to-one ing, but because the same number appears multiple times, an array is required and the length is not certai
