问题 I am getting below crash logs while using getMaxLines() method of Texview on Ice Cream Sandwich Android 4.0.3 version, So I got the real issue is, that my application is running lower sdk which does not have this getMaxLines() method. How can remove this crash. I didn't find any alternatives method java.lang.NoSuchMethodError: android.widget.TextView.getMaxLines at com.text.mobile.new.adapters.ServiceListAdapter.onBindViewHolder(ServiceListAdapter.java:232) at android.support.v7.widget

问题 The easy part: Targeting the .NET 2.0 framework in a Visual Studio 2010 project using the dropdown. The hard part: Is it possible to target a specific syntax version - for example var s = "hello world" is valid syntactic sugar in VS2008 and above, but would not compile in VS2005. Can VS2010 be configured to flag this at compile time? 回答1: This can be done by specifying the language version in the project settings. To set the language version to C# 2.0 do the following Right Click on the

问题 I need to make my code backwards compatible with python2.6 and BeautifulSoup 3. My code was written using python2.7 and at this case using BS4. But when I try to run it at squeezy server, I get this error (it has python2.6 and bs3): try: from bs4 import BeautifulSoup except ImportError: from BeautifulSoup import BeautifulSoup gmp = open(fname, 'r') soup = BeautifulSoup(gmp) p = soup.body.div.find_all('p') p = soup.body.div.find_all('p') TypeError: 'NoneType' object is not callable If I change

问题 Here is the story. I had integrated Google Drive Android SDK (8.1.0) into my app (AnyCopy) around three years ago. And I followed the tutorial to set up properly including adding credentials and api key. Everything worked okay. I could backup and restore my data without any problem. Even today it works okay if I download it from Google Play. Recently I have been trying to refactor AnyCopy and integrate the newest Google Drive Android SDK (Google Play Service Version number 12.0.1 )into my app

问题 TO display a list of items I am using the latest RecyclerView in my app. I want to know would it only work on devices having android 5.0 or would it on work on lower versions as well ? 回答1: Yes, it's backwards-compatible, assuming you include the support library for RecyclerView v7 in your application's build.gradle file: Make sure you have downloaded the Android Support Repository using the SDK Manager. Open the build.gradle file for your application. Add the support library feature project

问题 Sorry if I've worded the question a bit odd! Basically, I have a serializable class that has a single field at this current time, but will definitely gain more in the future as we add features to the system. The serialization process will be used for both passing instances to a WCF service, and for reading/writing it from/to file. Of course, the latter may be a big problem if I'm continually updating the class with extra fields. Luckily, I think I've solved the problem by adding a try/catch

问题 32-bit application executables contain machine code for a 32-bit CPU, but the assembly and internal architecture (number of registers, register width, calling convention) of 32-bit and 64-bit Intel CPU's differ, so how can a 32-bit exe run on a 64-bit machine? Wikipedia's x86-64 article says: x86-64 is fully backwards compatible with 16-bit and 32-bit x86 code. Because the full x86 16-bit and 32-bit instruction sets remain implemented in hardware without any intervening emulation , existing

问题 Basically I have this website that has been working very well in compatible mode IE7 for all versions of IE(I have used meta tag in IIS for this). Now issue is with IE10 where document mode is changing to IE Standards but Browser mode is not changing to be compatible. Can you please guide me to a solution for this. 回答1: Meta tag would change document mode for you whereas you still need to have fixed your application or server, this is a known issue. This would fix browser mode and combining

问题 The final committee draft of the upcoming C++0x standard says: Every C header, each of which has a name of the form name.h, behaves as if each name placed in the standard library namespace by the corresponding cname header is placed within the global namespace scope. It is unspecified whether these names are first declared or defined within namespace scope (3.3.6) of the namespace std and are then injected into the global namespace scope by explicit using-declarations (7.3.3).
