从Python程序中访问Java类的简单示例

from jnius import autoclass
> Stack = autoclass('java.util.Stack')
> stack = Stack()
> stack.push('hello')
> stack.push('world')
> stack.pop()
'world'
> stack.pop()
'hello'

from jnius import autoclass
from time import sleep
 
MediaRecorder = autoclass('android.media.MediaRecorder')
AudioSource = autoclass('android.media.MediaRecorder$AudioSource')
OutputFormat = autoclass('android.media.MediaRecorder$OutputFormat')
AudioEncoder = autoclass('android.media.MediaRecorder$AudioEncoder')
 
# Record the Microphone with a 3GP recorder
mRecorder = MediaRecorder()
mRecorder.setAudioSource(AudioSource.MIC)
mRecorder.setOutputFormat(OutputFormat.THREE_GPP)
mRecorder.setOutputFile('/sdcard/testrecorder.3gp')
mRecorder.setAudioEncoder(AudioEncoder.ARM_NB)
mRecorder.prepare()
 
# Record 5 seconds
mRecorder.start()
sleep(5)
mRecorder.stop()
mRecorder.release()
