Dip: Device Independent pixels (device independent pixel ). Different devices have different display effects, which are related to the hardware of the device. We recommend that you use this function to support WVGA, hvga, and qvga without pixels.Density-independent pixels, an abstract unit based on the physical density of the screen. Density can be understood as the number of pixels per inch (unit: DPI). 1dp is actually equivalent to a point on the screen with a density of DPI (can it be underst

At the beginning, the simulator I selected was WVGA854 with a resolution of 854*480. After the development, I felt very OK when I installed it on a 800*480 mobile phone, but when I installed it on a 480*320 or 320*240 resolution mobile phone, many interfaces were distorted, at this time, I felt the importance of app self-adaptation. Adaptive mainly encounters two

set. STL writes an iterator for each set. The iterator packs a pointer and implements some common methods, such as ++ ,--,! =, =, *,->, Etc. You can use these methods to find the current element or other elements. vector is a special element in the STL set. Because every element in the vector is continuous, you can replace it with a pointer when implementing the vector yourself, such as typedef T * iterator; typedef const T * const_iterator.
