In the previous article, we briefly introduced the surfaceflinger service in the surface mechanism of the Android system. The surfaceflinger service is started in the system process and is responsible for unified management of the device's frame

In programming, we often encounter the requirements for calling member functions through function pointers in a "class", such, when the sorting function qsort in the C ++ standard library is used in a class, because the qsort parameter requires a

The list stores elements in the linked list sequentially. Compared with the vector, the list allows fast insertion and deletion, but random access is slow. Member functions(Constructor)Construct list (public member function) // Construct a linked

Unordered_map, like map, are stored key-value values that can be quickly indexed to value by key.The difference is that the unordered_map will not be sorted according to the size of the key, the storage is based on the hash value of key to determine

In the previous article, we analyzed the creation process of the runtime context of the Android application window. It follows that each activity component has an associated Contextimpl object, and It also associates a window object to describe a

Assume that the screen class defines four new member functions: Forward () Back () Up () and down (). They move the cursor to the right, left, up, and down, respectively. First, we declare these new member functions in the class body: Class Screen

In the previous article, we analyzed the creation process of the running context of the Android application window. It follows that each activity component has an associated Contextimpl object, and it also has a window object associated with it that

Assume that the screen class defines four new member functions: Forward () Back () Up () and down (). They move the cursor to the right, left, up, and down, respectively. First, we declare these new member functions in the class body: Class Screen

Class Definition details in C ++ Member variables Each class can have no members or multiple members. The members can be data, functions, or type aliases. A class can contain several public, private, and protected parts. Members defined in the

In the previous article, we analyzed the creation process of the runtime Context Environment in the Android Application Window. It can be seen that each activity component has an associated contextimpl object, and it also associates with a window
