Android custom control Series 10: handles touch event distribution by adding custom la S, and responds to events in specific directions by using specific controls in the combination interface. android Custom Controls
This example is quite useful. It can be basically said that after writing this time, you can take it directly in many cases.AddViewAnd thenAddInterceptorViewYou can easily implement a specific control in the combination interface to respo
Android View event distribution mechanism
Recently, I encountered a view slide conflict during development. As I knew from the very beginning that this problem was related to view event distribution, after reading a few articles about event distribution on the Internet, problems encountered during development are quickly solved.Here I will summarize my understand
There are three parts in lecture4:
Newton's method Newton Method
Exceponential family exponential distribution family
Generalized Linear models generalized linear model (GLMS)
The Newton method, as mentioned in the previous article, is another optimization algorithm parallel to the gradient descent algorithm.
Then, the video proves that the bernuoli distribution and Gaussian
OverviewAndroid event delivery mechanism is also an important piece of the Android system, there are many types of events, here mainly discusses the TouchEvent event in the framework layer of the transfer processing mechanism. Because for app developers, understanding the event passing mechanism of the framework layer is almost there.Think about the entire event distribution process with questions.1, why should there be an event
First, use the Visual Studio tools to see the memory distribution of the class, as follows:Select the c/c++-> command line on the left and then write the/d1 reportallclasslayout on the other option, which can see the memory layout of all related classes, if written on/d1 Reportsingleclasslayoutxxx (XXX is the class name), only the memory layout of the specified class XXX will be typed. This configuration is supported in recent VS versions.Below you ca

In normal development, we often encounter events such as clicking, sliding, and so on. Sometimes there are all kinds of sliding conflicts between different view. For example, both inside and outside the layout can be sliding, then there will be conflicts. This is when we need to know about the Android event distribution mechanism.The Android Touch event distribution process is done in three important ways:

4G indoor distribution construction solution
How to Implement indoor coverage has become the biggest challenge facing operators in the 4G era. Compared with 3G networks, the 4G indoor distribution system pays more attention to refined indoor coverage. system indicators should not only focus on field coverage, but also on capacity, signal quality, switching, frequency, and interference, and network construc

Android Touch gesture distribution and androidtouch gesture
In the Touch distribution in android, we often see ACTION_DOWN-> ACTION_MOVE-> ACTION_UP. When we don't know how it is distributed, we always feel confused, therefore, it is necessary to understand its overall distribution process, so it is necessary to keep a good record.

Android event Distribution
Methods related to Touch events in Android include dispatchTouchEvent (MotionEvent ev), onInterceptTouchEvent (MotionEvent ev), and onTouchEvent (MotionEvent ev) From this table, we can see that ViewGroup and its subclass can respond to the three methods related to Touch events, while Activity does not respond to onInterceptTouchEvent (MotionEvent ev), that is, event interception. In addition, you must note that the View res

Send asynchronously
ACTIVEMQ The default send mode is asynchronous send, if we use the scene is non-transactional type or need to persist the message, allow a small number of messages to be lost, it is recommended to use asynchronous send. Synchronous sending requires an acknowledgement of increased ACK, which increases latency and system consumption.
