Kuidas toimub sõnumite töötlemine Looper komponendi sees?

The Looper component in Android is responsible for the message processing cycle (MessageQueue) in a thread. It works as follows:

1. A Looper is created for the thread and linked to its message queue (MessageQueue).
2. In an infinite loop, the Looper extracts the next message from the queue.
3. The message is passed to the appropriate Handler for processing.
4. After processing, the Looper moves on to the next message.

This way, the Looper ensures sequential processing of messages and events in the thread, enabling asynchronous processing.

Example of usage:

Looper.prepare(); // Initializes the Looper for the current thread
Handler handler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        // Message processing
    }
};
Looper.loop(); // Starts the message processing loop

This allows, for example, in the main thread of Android, to process UI events and other tasks.
