Implementation of loading an animation I remember seeing an animation design above, and I tried to implement it. First, we can see that the animation is composed of two parts, one circle rotates clockwise, and the other is the linear movement of dots, there is a time difference between the dots, and the superposition of the two motion forms this rolling effect. Figure 1, Figure 2, and figure 3 Figure 1 show

Package Com.kcode.autoscrollviewpager.view; Import Android.content.Context; Import Android.os.Message; Import Android.su

Pixel and millimeter conversions The transformation also needs to know another parameter: DPI (how many dots per inch) Number of pixels/DPI = inches Number of inches * 25.4 = mm There is a common way to display devices, whether they are printers or screens. First with GetDeviceCaps (device handle, LOGPIXELSX) Or GetDeviceCaps (device handle, logpixelsy) gets the number of pixels per inch of the device Note separately: px and py One inch equals 25.4mm

When a page executes for a long time, such as a large amount of data query, and so on. You can use the following method to display prompts for the user.

If the escalation data is currently being analyzed. When the analysis is complete, prompt the user for "currently writing XML fil

first, the initialization of Proper weight initialization can prevent gradients from exploding and disappearing. For Relu activation functions, weights can be initialized to: Also known as "he initialization". For Tanh activation functions, the weights are initialized to: Also known as "Xavier initialization". You can also use the following formula to initialize: In the above formula, L refers to the first layer of the neural network, L-1 is the upper layer. second, the programming work Have
