android GridView prohibited item to get focus, seeking big cow!

android gridview STB

Recently made a set-top box applications, demand is horizontal scroll two rows of data;
My solution is:
HorizontalScrollView + GridView, but if you use the focus control scrolling, it must prohibit the item gets the focus, so to gridview set myGridView.setDescendantFocusability (ViewGroup.FOCUS_AFTER_DESCENDANTS);
But there is a problem after scrolling when scrolling to the end, the focus away from gridview then came in, the focus will jump directly to each item in the first, but not into the nearest item, what is the reason?
Been tested, regardless of whether there are sets of rolling out GridView control, even if it is a separate GridView, as long as the set myGridView.setDescendantFocusability (ViewGroup.FOCUS_AFTER_DESCENDANTS);
So the focus away from the GridView, then come all the direct jump to the first item inside, rather than entering from outside Button recent item.
Solving! How to solve this problem?

Andrews third-party applications memory logcat debug

Such as the title, now encounter a problem in their own equipment installed on the application of a third party, but the applications have problems, too much log information about printing, resulting in a serious impact this program to run the system, ultra-high memory share.

The problem is that there is no way (or input a command) can print all the log information systems are turned off, or just turn off debug level, it will be open to err level? ?

I do not mean that.
logcat just log information is displayed, even if you do not log, there are still a steady stream of information output outside, but is not showing it.
So I want to do is how to put this log from the source stopped, do not want foreign output, similar to its own program code Log.d like commenting,

My question is actually system.extit (0) can close those things, why he can not shut down the service, the service is run in the main thread. And the same process, but he did not shut down.

In Java, you can use this method to end the whole application in android, this method can also be turned off Activity, but the kind of situation needs attention: the service if it is open and Activity bound together, when the Activity is kill off service also will be to kill off; If the service does not bind together and Activity, when the Activity is to kill off, service was not immediately kill off, I do not know LZ can understand.

Meaning of existence is service running in the background, if it will be destroyed along with the main thread that their meaning is basically gone! If you want to close it manually in ondestory inside!

I know this conclusion, but also have done, but now understand clearly.
system.exit (0) off the virtual machine memory, that is, kill off the current process. And why start the service will not be killed because of a service is the default start is to start a process to run. So with such a conclusion is not all of the activity or service they are set in the same process if it can system.exit (0) completely out of the system? Attempt

I do not understand, service and activity has always been in the same thread, activity hung up, should have hung up the fishes service, but did not. . .

After the activity if not bind together with the service, then call system.exit (0) in the activity, the entire process really quit immediately, but you carefully watch what log system, there will be a schedule restart your yingyongming 5000ms later, that is, said the system will reboot your service, you can be a test test

} 

Then, in the Activity call as follows:

Discovery opens the application, even if the data is not displayed.
The MainActivity realized OnScrollListener, made an asynchronous thread, load the data when the finger paddling when they can show up, but every time it loads all the data is displayed, not only demonstrate the new additions

 
private class GetDataTask extends AsyncTask  {

See friends said in the main thread which can not have network operations or database operations, so that a few lines of code to get the data into several DEMO initialization data from the database in the Activity, found that this can show up.

So you can think straight points to open the display data in the database should be how to operate it? Also use asynchronous way?

The most critical is that when clicking refresh, why always repeat refresh all data?

Not familiar with programming for android, ask two questions

Not familiar with programming for android, ask two questions
First, read and write files, how to read and write the specified location, such as a file has 1024 bytes, I want to read only the first 500 bytes to 600 bytes how to do, is not necessarily to read 600 bytes and then throw away the first 500 bytes, which is not what I want, for example, if the file has 2G, 2G wholly impossible to read out of it
Second, the layout is definitely not recommended, but I want to run after the program is able to set my interface, want to put the button onto the place, it could change the button layout is definitely replace what way. (Originally under 2.3 can be used with absolute layout, now at 4.2 operating under the same code to die, is not the absolute layout is no longer supported)

Unless you just absolutely layout application screen adaptation, and now so many android phones, various screen sizes, resolutions. Absolute layout barely use.

I am a novice, the original will be c + +, just turn around, thank you for your ideas, but I checked the FrameLayout, all placed in the layout of the controls are in accordance with the level of the stack in the upper left corner of the screen. After covering the front of the controls add to the mix of control. In FrameLayout layout, the definition of the location of any space-related properties are meaningless. I do not know how to use this stuff, I just want to define the location of properties that it actually meaningless. Also, my original phone is version 2.3, 4.2 out change, and when the absolute layout think so, get pixel screen before each run, the location information stored in my control is a logical value, the screens average into 1000 points, on a different phone, the screen pixel by 1000, the value obtained by multiplying the coordinates of my control, the size of the value, and then show up, there should not have different phone display is not the same situation

Reply:
1, the first question simply does not belong to Android development problem is the problem of Java IO streams, the landlord can see Java SE related knowledge. Well, the foundation is very important.

2, you can use a nested layout. Think the layout can be achieved with relative effect of what you said.
Reply:
The knot posted, youngc527 first question has been answered, the second question I have actually achieved relative layout, but more complex than absolute layout, but also larger than the absolute limit distribution, relative layout controls only need to save their left , top, width, height on the line, relative to the layout have to remember what the controls around, what is the relationship with the surrounding controls, is very complex, it issued the complaint.

A better approach is: a good return on both sides to define the data format, preferably json format, which can be google can also be apache, and analytical tools so that you can be here when parsing apache provided by google or , very convenient.

Position offset is too large, then consider whether or not to engage in bad latitude and longitude
Reply:
I considered this reason, did not write bad ah

Reply:
Click to get MyLocationListener inside debug precision latitude, see if it is the correct value, whether the positioning, whether to get into the accuracy of latitude

Design problems Andrews login client, help ~ ~ ~ ~ ~ ~ ~

eclipse Andrews server database tomcat

Using C / S structure, the back-end server using MyEclipse Servlet written in connection with the database login interface with tomcat release, front design with Eclipse Android client, how to connect client and server side of it? The client can be achieved by a successful login account password, seeking detailed advice? I am a novice, the first contact with such things, there are a lot of vacant places, hope to have expert advice!

Your own ideas is not very clear yet.
Client and server links related to Socket Programming. If the client and server connected, and you can pass the login information (such as user name, password) in between, in the background doing verification. Is there any question it. .

Why not have the address, port number, not have it, the machine is not localhost: ip chant changed to native

Just getting started, then use http to achieve the transfer of data to a simple point of it

android client uses HttpURLConnection or HttpClient

Android 4.2 Wireless display to communicate with the PC

Android 4.2 has a Wireless display technology, the sound through wireless image transfer to a TV or other tablets to support the technology.

Now the question is, is there a way to image the Tablet PC, transfer the sound to the PC computer via Wireless display technology?
To say the least, no longer limited to the transmission mode Wireless display, as long as there is a viable way to synchronize voice data tablet PC computer, are possible.
For PC computer's operating system is limited to Windows and Linux platforms.

You greatly who have any suggestions or relevant aspects of the item?

Ah, thank you reply.
However, this involves capturing the image and sound systems, better images, sounds, then read a lot of ways, so far no one is entirely feasible, there is always this kind of problems or limitations.

httpclient () post a wonderful question!

httpclient () post http android

 private String connServerForResult (String path, String contents) {
/ / TODO Auto-generated method stub 
HttpClient client = new DefaultHttpClient (); 
String json = null; 

try {
/ / Destination address 
HttpPost request = new HttpPost (path); 
/ / Constructor string data 
StringEntity entity = new StringEntity (contents); 
/ / Set the type 
entity.setContentType ("application / x-www-form-urlencoded"); 

entity.setContentEncoding (new BasicHeader (HTTP.CONTENT_ENCODING, HTTP.UTF_8)); 
Data 
 / / Set requestrequest.setEntity (entity); 
/ / Execute 
HttpResponse response = client.execute (request); 
HttpEntity httpentity = response.getEntity (); 
/ / Result 
json = EntityUtils.toString (httpentity); 
System.out.println ("account" + json); 
} Catch (Exception e) {
e.printStackTrace (); 
} 
return json; 
} 
}; 

This is the code! When tested post no problem! But the real address changed after the server can not obtain the data I post up! Can return an error message! This is what ah? (Server code is the same)

Determine under your server address is correct, see what type of error return. Whether the server receives a request
Reply:
respones can see the code, and a code to see what is wrong, and then re-check the correctness of combining url

Themselves! Is the problem server address!
