android studio上的字符串限制 [英] String limit on android studio
问题描述
我真的是Android Studio和Java编程的新手.
i am really new to Android Studio and java programming.
我试图创建一个新项目，只是为了进行实验和学习.
im trying to create a new project, just to experimenting and learning.
这个应用程序有很长的文字，我使用字符串来格式化它，也可以作为资源.
this app there is long text and i using string to format it and also as resources.
但是，经过1400多种文字和格式设置后，活动崩溃了.
however, after 1400+ text and formatting, the activity crash.
我可以知道字符串资源是否有一些限制?
may i know is there some limit on string resources ?
以及解决问题的方法是什么?
and what is the way to overcome the problems ?
我想出要使用原始文本，但是根据我目前的理解，无法像字符串一样格式化它.
i figured out to use raw text, but on my current understanding, there is no way to format it like strings.
真的很感谢有人能帮忙.
really appreciate if anyone can help.

推荐答案
String.length()方法返回字符串的长度.字符串的长度等于字符串中Unicode单元的数量.Java平台在char数组(每个字符占用两个字节)，String和StringBuffer类中使用UTF-16表示形式.
String.length() method returns the length of the string. The length of the string is equal to the number of Unicode units in the string. The Java platform uses the UTF-16 representation in char arrays (each character takes two bytes), String, and StringBuffer classes.
该方法返回int类型的长度.因此，字符串最大大小与整数数据类型的范围相同.该方法将返回的最大长度为 Integer.MAX_VALUE .
The method returns the length which is of type int. So, the String maximum size is the same as the range of integer data type. The maximum length that would be returned by the method would be Integer.MAX_VALUE.
Java中int的大小为4个字节(包括一个带符号的位，即MSB).整数数据类型的范围是-2 31 到2 31 -1(-2147483648到2147483647).请记住，我们不能使用负值进行索引.索引在最大范围内完成.这意味着我们无法存储2147483648th个字符.因此，Java中String的最大长度为0到2147483647.因此，从理论上讲，我们可以拥有长度为2147483483647个字符的String.
The size of int in Java is 4 bytes (included a signed bit, i.e. MSB). The range of integer data type is -231 to 231-1 (-2147483648 to 2147483647). Remember that we cannot use negative values for indexing. The indexing is done within the maximum range. It means that we cannot store the 2147483648th character. Therefore, the maximum length of String in Java is 0 to 2147483647. So, we can have a String with the length of 2,147,483,647 characters, theoretically.
import java.util.Arrays;
class StringMaxSize {
public static void main(String args[]) {
for (int i = 0; i < 1000; i++) {
try {
//Integer.MAX_VALUE is a constant that stores the maximum possible value for any integer variable
char[] array = new char[Integer.MAX_VALUE - i];
//assign the specified data value to each element
Arrays.fill(array, 'a');
//creating a constructor of the String class and parses an array into it
String str = new String(array);
//determines and print the length of the string
System.out.println(str.length());
} catch (Throwable e) {
// returns the detail message string of this throwable
System.out.println(e.getMessage());
//prints the maximum value
System.out.println("Last: " + (Integer.MAX_VALUE - i));
System.out.println("Last: " + i);
}
}
}
}
输出:
因此，1400多个文字不是实际的问题.
So, 1400+ text is not the actual issue.
