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'
上面的代码中,我们使用 autoclass 函数,创建了一个类型代理,对应着Java中java.util.Stack类的所有方法和字段属性。
OK,也许你想要一个Android相关的例子,看这里:
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()
好了,你可以从文档中获取更多的例子。
我们已经可以映射Java/Python的类型,原生数组,支持方法重载等等。我们在内部使用的是 Cython + JNI,因此消耗性能是最小的。
同时, Python for android库已经完成,你可以从github中获取。

You can learn basic programming concepts and skills of Python within 2 hours. 1. Learn variables and data types, 2. Master control flow (conditional statements and loops), 3. Understand the definition and use of functions, 4. Quickly get started with Python programming through simple examples and code snippets.

Python is widely used in the fields of web development, data science, machine learning, automation and scripting. 1) In web development, Django and Flask frameworks simplify the development process. 2) In the fields of data science and machine learning, NumPy, Pandas, Scikit-learn and TensorFlow libraries provide strong support. 3) In terms of automation and scripting, Python is suitable for tasks such as automated testing and system management.

It is impossible to view MongoDB password directly through Navicat because it is stored as hash values. How to retrieve lost passwords: 1. Reset passwords; 2. Check configuration files (may contain hash values); 3. Check codes (may hardcode passwords).

As a data professional, you need to process large amounts of data from various sources. This can pose challenges to data management and analysis. Fortunately, two AWS services can help: AWS Glue and Amazon Athena.

To read a queue from Redis, you need to get the queue name, read the elements using the LPOP command, and process the empty queue. The specific steps are as follows: Get the queue name: name it with the prefix of "queue:" such as "queue:my-queue". Use the LPOP command: Eject the element from the head of the queue and return its value, such as LPOP queue:my-queue. Processing empty queues: If the queue is empty, LPOP returns nil, and you can check whether the queue exists before reading the element.

Question: How to view the Redis server version? Use the command line tool redis-cli --version to view the version of the connected server. Use the INFO server command to view the server's internal version and need to parse and return information. In a cluster environment, check the version consistency of each node and can be automatically checked using scripts. Use scripts to automate viewing versions, such as connecting with Python scripts and printing version information.

The steps to start a Redis server include: Install Redis according to the operating system. Start the Redis service via redis-server (Linux/macOS) or redis-server.exe (Windows). Use the redis-cli ping (Linux/macOS) or redis-cli.exe ping (Windows) command to check the service status. Use a Redis client, such as redis-cli, Python, or Node.js, to access the server.

Navicat's password security relies on the combination of symmetric encryption, password strength and security measures. Specific measures include: using SSL connections (provided that the database server supports and correctly configures the certificate), regularly updating Navicat, using more secure methods (such as SSH tunnels), restricting access rights, and most importantly, never record passwords.
