For many games that use screen control, you generally need to consider the long-press event. For example, in a gossip game, you need to use the long-press launch weapon. In combination with the android button model, we implement a long-press of a button with an image, for a clearer display principle,

example, there are two Android simulators, 5556 can send a aaasss sms to 5554.After that, the volume app listens and pops up a message.At the same time, I press and hold the "long press Back to desktop" button to return to the desktop.This is the same call here, but the simulator does not call this component, here can not be displayed.1, the first res\values\strings.xml in each character file as follows, n
mobile wireless network.Features of mobile wireless networks:Because IP v4 IP is limited, the operator assigned to the mobile phone terminal IP is the operator intranet IP, mobile phone to connect to the Internet, you need to do a network address translation through the operator's Gateway ("Networking Translation,nat"). Simply said that the operator's gateway needs to maintain an external network IP, port to the network IP, port correspondence, to ensure that the intranet phone can communicate

After the installation is complete, if you start directly, Android Studio will go to get the Android SDK component information, this process is quite slow and often fails to load, causing Android studio to start up. The solution is not to get the Android SDK component information. Here's how:1) Go to the bin directory

So the push can't be used, Android developers have to maintain a long link, so each application if all 24 hours online, then all have to maintain a long
This problem is encountered in the project:Since the keys in the system have been redefined or new keys are added, it is necessary to decompose the key events (KeyEvent) in the app layer, simulating the Android system practice and decomposing the keyevent into:1, click the event: is the ordinary key click;2, double-click the event: 500ms within the same keystroke two times;3, Long press event: The same key
Android parsing --- DragGridView long by dynamic sorting, androidview
To implement a DragGridView effect similar to the previous ZAKER news reading. However, horizontal cross-screen is not required, but vertical cross-screen. There are also a lot of resources on the Internet, there are horizontal cross-screen, but not find the vertical. Later, I had to modify the code one or two by one.

Today, when doing demo, we need to set the long press and click events of the ListView item, Onitemlongclicklistener and Onitemclicklistener, however, the Click event can be implemented, and the long time operation will trigger the Click event simultaneously. Then look at the relevant source of Android, you can see the system is the priority of the corresponding
Android provides the gesturedetector class to process some commonly used gesture operations, such as onlongpress and onfling. However, gesturedetector is not used here, but is directly processed in the ontouchevent of the custom view rewriting.
To achieve this, if the mobile phone does not move (for example, 500 ms) within the specified time when holding down the screen, it enters the long-press mode, in th
Android long press the power key to shut down the entire process to learn
I recently studied the android shutdown and restart functions, and read a series of processing processes from long-pressing power keys to the pop-up shutdown dialog box and real shutdown.
First, let's take a look at what this
For the touchscreen, its native message simply presses, lifts, and moves these kinds of things, we just need to simply overload Ontouch or set the touch listener Setontouchlistener can be processed. However, in order to improve the user experience of our app, sometimes we need to identify the user's gestures, and Android gives us the gesture recognition tool gesturedetector can be a big help.
