I have an error in a thread making time "run" (update every second)

Here is my code:

public void run() {
        try {
            while (!isInterrupted()) {
                Thread.sleep(1000);
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {

                    }
                });
            }
        } catch (InterruptedException e) {
        }
    }
};
thread.start();

The Thread is called Thread and I want to display the time in a TextView called TextView. There is some error in the Threadbecause even though the time displays in the TextView, it does not update every second. Thanks

As stated, you should use Handler with Runnable, here is an example with your code:

final Handler handler = new Handler();
final Runnable task = new Runnable() {
    @Override
    public void run() {
        //Your code
        handler.postDelayed(this, 1000);
    }
};
handler.postDelayed(task, 1000);

More info about Handlers, in the doc.

use Runnable And Handler

Runnable runnable = new Runnable() {
    @Override
    public void run() {

        Date time = Calendar.getInstance().getTime();
        textView.setText(DateFormat.format("hh:mm", time));

        handler.postDelayed(this, 1000);
    }
};

Handler handler = new Handler();
handler.post(runnable);
