Fragment status switch and fragment status Switch
When you use Activity to manage multiple Fragment, replace is used for each Fragment switchover. As a result, xxx is not currently in the FragmentManager fails.
On the Internet, if replace is used for switching, the switched Fragment will be replaced, and the switched Fragment view will be deleted from the viewtree. As a result, the Fragment will be re-creat
A label event is typically written in this way, or it may be a binding event, in the same way:

Just add a return false after
First step
Open the mobile phone QQ, with the fingers to slide, call out the left menu, as shown in the following figure
Second Step
Then click "Settings" in the Open menu as shown in the picture
Third Step

The problem is as follows: The problem is obvious. Off the last F because the line-wrapping led to be propped up, through debugging found in the CSS to introduce such a fragment:
* {
word-wrap:break-word;
}
This means that all element text takes a strategy to break the word when it is not in line.
Solution in 2:
1. Try to find the above CSS file, and then remove it. Not recommended.
2. A better approach would be to rewrite the BOOTSTRAP-SWITCH.CSS

the console line. A few years ago, desktops, notebooks, and server devices would configure a DB9 interface on the motherboard and then use the console line to connect the switch to the computer. Now, because of technology change, notebook and desktop, will not bring DB9 interface, replaced by USB interface, so, do network engineering, must prepare two lines, one is the console line, one is USB to DB9 line. Then connect t

Speed-limiting switches are typically on three or more switches, and the new switch model two-tier device since 2008 can achieve the QoS speed limit of 1Mbps, such as the Cisco 2960 series switches. After this, most of the domestic standard two-layer switches can be long speed limit, the accuracy of the basic can reach 1Mbps, such as ZTE's standard two layer, H3C standard two layer can do. Older Cisco standard two-layer switches such as 2950-class swi
Experiment on single-arm routing using a layer-3 Switch
In the real environment, sometimes the gateway is not necessarily enabled on the router, sometimes the single-arm routing function is not necessarily connected to the interface on the router, you can use a layer-3 switch, because the vswitch itself has a variety of interfaces for flexible use, it is very common in practical work. Readers can compare th
Absrtact: Spanning tree algorithms and protocols are the basis for automatically generating network topologies. This paper expounds the content of spanning tree algorithm and protocol, and gives the realization process in Ethernet switch. It is proved by practice that the square tip has a good effect on the analytic optimal topological structure of the network.
The Ethernet switch must have routing capabil

The switch is an important connection "hub" in the LAN, once its working status is unexpected, then all the computers connected to the switch have to "suffer", light is the phenomenon of slow surfing the internet, serious words simply can not go online, for this choice of superior performance, quality of the switch to form some important network, is very critical
