1.安装
pip install Cpython
pip install Pyjnius
2.说明书
https://pyjnius.readthedocs.io
3.使用自定义的类或jar文件
要想使用自定义的class/jar文件必须修改 CLASSPATH环境变量
1.将.class文件打包成jar,然后将CLASSPATH指定jar的路径
import os
os.environ['CLASSPATH'] = '/home/aaron/workspace/javatest.jar'
2.将.class文件路径指向CLASSPATH
import os
os.environ['CLASSPATH'] = '/home/aaron/workspace/JavaTest/bin'
3.通过jnius.config修改CLASSPATH
import jnius_config
jnius_config.set_classpath('.','/home/aaron/workspace/JavaTest/bin')
from jnius import autoclass
javatest = JavaTest()
javatest.hi()
4.示例
>>> from jnius import autoclass
>>> autoclass('java.lang.System').out.println('Hello world')
Hello world
>>> Stack = autoclass('java.util.Stack')
>>> stack = Stack()
>>> stack.push('hello')
>>> stack.push('world')
>>> print(stack.pop())
world
>>> print(stack.pop())
hello
5.进阶
from time import sleep
from jnius import MetaJavaClass, JavaClass, JavaMethod, JavaStaticMethod
class Hardware(JavaClass):
__metaclass__ = MetaJavaClass
__javaclass__ = 'org/renpy/android/Hardware'
vibrate = JavaStaticMethod('(D)V')
accelerometerEnable = JavaStaticMethod('(Z)V')
accelerometerReading = JavaStaticMethod('()[F')
getDPI = JavaStaticMethod('()I')
# 使用这个新类
print('DPI is', Hardware.getDPI())
Hardware.accelerometerEnable()
for x in xrange(20):
print(Hardware.accelerometerReading())
sleep(.1)
