android - 无法在带有大文本的 Android TextView 中显示 Unicode 字符(表情符号):“字体太大,无法放入缓存”
我正在尝试在 TextView 中显示单个 Unicode 字符(表情符号),其文本大小较大(r):
该字符未出现在屏幕上,并且我在 logcat 中收到此错误:
工作的最大尺寸是
并出现表情符号字符。它不像是全屏或任何东西,在这个文本大小下,屏幕上有足够的空间容纳大约 6 个表情符号字符。
我在运行 Android 5.1.1 的 LG Nexus 5 手机上运行测试,分辨率为 1080 x 1920。我正在使用minSdkVersion 11和targetSdkVersion 23
我尝试了在 StackOverflow 和其他地方找到的许多解决方法:
没有任何效果。
有没有办法让它工作?

multithreading - High CPU usage by unknown process in multithreading
We have server with 35gb memory and Intel® Xeon(R) E5-1620 0 @ 3.60GHz × 8 CPU. I am running a multithreaded program designed with akka actors and written in scala. In the program, there are 4 actors with tasks:
1) Lazy reading from file with Scala's BufferedSource and iterator,
2) Tokenizing sentences,
3) Calculating single and bigram words frequency for a given window size, and putting them into a map (one map for single words [String, Int], one for tuple words[WordTuple,Int),
4) Merging returned hasmaps into one hashmap and when all lines read from file and write them into a file.
My custom jvm settings is as follows:
-Xms34g
-Xmx34g
-XX:ReservedCodeCacheSize=240m
-XX:+UseParallelGC
-XX:ParallelGCThreads=4
-XX:NewSize=12g
-XX:SoftRefLRUPolicyMSPerMB=50

-Dawt.useSystemAAFontSettings=lcd
-Dsun.java2d.renderer=sun.java2d.marlin.MarlinRenderingEngine
-verbose:gc
-XX:+PrintGCDetails
-Xloggc:gc.log
My application.conf is as follows:
The problem:
I am processing a text file with size 15gb. Program starts working, after a while, say 2 hours, those tokenizing, calculating operations is almost not working, no operations can perform. The operation that takes 300 milliseconds starts taking 100000 seconds. But the cpu usage is %100 for all processors. I've tried using jvisualvm to motinor it but sampler is not working with this high cpu usage, so I could not identify which process is making cpu %100. I check gc activity from jvisualvm and most of the time it is using about %10 cpu. So, what could be the problem with my program, which process is possibly using all the cpu?
Here some screenshots from jvisualvm when operations in the program is stop but cpu usage is %100:

Hope I explained it clear. Thanks in advance for your answers.
mysql - mysql中的数据类型大小和存储
我是使用 mysql 数据库的初学者。我正在尝试将用户数据保存在一个大型 Json 文件中,在最坏的情况下,该文件的大小约为 5Mb,很明显我应该使用 LARGE TEXT,但我想知道 11Mb 的其余部分会发生什么。是不是浪费了?
python-3.8 - 如何解决 Python 中的内存错误?
下面的程序,当文本文件中的记录数约为 6,000,000 PLUS 时,从由分隔符“~”分隔的文本文件中提取一些特定的列值会引发内存错误。但是,相同的片段适用于文本文件中较少数量的记录。我尝试使用列表理解,但无法解决内存错误。下面是代码片段:
样本输入数据格式如下:
P~LNL~22248370~50~22248370~20190916~20191112~20190916~002~I~A~N~003~1638~01~001~400023~-1552~20190916~0200058~001~X~~TMID~ ~~000~000~~000~000~000~~000~000~0~~~~N~~~
收到的错误如下:
