如果有人正在寻找一个快速的解决方案，请随意使用以下helper类:)
public class Log {
public static final String ANSI_RESET = "\u001B[0m";
public static final String ANSI_BLACK = "\u001B[30m";
public static final String ANSI_RED = "\u001B[31m";
public static final String ANSI_GREEN = "\u001B[32m";
public static final String ANSI_YELLOW = "\u001B[33m";
public static final String ANSI_BLUE = "\u001B[34m";
public static final String ANSI_PURPLE = "\u001B[35m";
public static final String ANSI_CYAN = "\u001B[36m";
public static final String ANSI_WHITE = "\u001B[37m";
//info
public static void i(String className, String message) {
System.out.println(ANSI_GREEN + className + " : " + message + ANSI_RESET);
}
//error
public static void e(String className, String message) {
System.out.println(ANSI_RED + className + " : " + message + ANSI_RESET);
}
//debug
public static void d(String className, String message) {
System.out.println(ANSI_BLUE + className + " : " + message + ANSI_RESET);
}
//warning
public static void w(String className, String message) {
System.out.println(ANSI_YELLOW + className + " : " + message + ANSI_RESET);
}
}
用法:
Log.i(TAG,"This is an info message");
Log.e(TAG,"This is an error message");
Log.w(TAG,"This is a warning message");
Log.d(TAG,"This is a debug message");

失败:
public static final String ANSI_STRIKEOUT_BLACK = "\u001B[30;9m";
public static final String ANSI_STRIKEOUT_RED = "\u001B[31;9m";
public static final String ANSI_STRIKEOUT_GREEN = "\u001B[32;9m";
public static final String ANSI_STRIKEOUT_YELLOW = "\u001B[33;9m";
public static final String ANSI_STRIKEOUT_BLUE = "\u001B[34;9m";
public static final String ANSI_STRIKEOUT_PURPLE = "\u001B[35;9m";
public static final String ANSI_STRIKEOUT_CYAN = "\u001B[36;9m";
public static final String ANSI_STRIKEOUT_WHITE = "\u001B[37;9m";
在Java中用红色打印任何文本的最佳解决方案是:
System.err.print("Hello World");
使用颜色功能打印带有颜色的文本
代码:
enum Color {
RED("\033[0;31m"), // RED
GREEN("\033[0;32m"), // GREEN
YELLOW("\033[0;33m"), // YELLOW
BLUE("\033[0;34m"), // BLUE
MAGENTA("\033[0;35m"), // MAGENTA
CYAN("\033[0;36m"), // CYAN
private final String code
Color(String code) {
this.code = code;
}
@Override
String toString() {
return code
}
}
def color = { color, txt ->
def RESET_COLOR = "\033[0m"
return "${color}${txt}${RESET_COLOR}"
}
用法:
test {
println color(Color.CYAN, 'testing')
}
下面是带有公共静态字段的Java类中的颜色列表
使用
System.out.println(ConsoleColors.RED + "RED COLORED" +
ConsoleColors.RESET + " NORMAL");
请注意 不要忘记在打印后使用RESET，因为如果它没有被清除，效果将仍然存在
public class ConsoleColors {
// Reset
public static final String RESET = "\033[0m"; // Text Reset
// Regular Colors
public static final String BLACK = "\033[0;30m"; // BLACK
