Question

我正在使用一个循环进度条，它有一个倒数计时器，持续10分钟。 Progressbar工作正常，但不顺畅.Below是我的循环进度条的代码。

public class MainActivity extends AppCompatActivity {
    ProgressBar barTimer;
    CountDownTimer countDownTimer;
    TextView textTimer;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        barTimer = findViewById(R.id.barTimer);

        barTimer.setProgress(100);
       barTimer.setMax(100);
        startTimer(10);

    }

    private void startTimer(final int minuti) {
        countDownTimer = new CountDownTimer(60 * minuti * 1000, 1000) {
            @Override
            public void onTick(long leftTimeInMilliseconds) {

                long seconds = leftTimeInMilliseconds / 6000;

                barTimer.setProgress((int)seconds);

            }
            @Override
            public void onFinish() {

            }
        }.start();

    }
    }

任何人都可以帮助我如何使进度条顺利进行。

我只是将进度条划分为1000个部分并且每100毫秒调用一次以便它会更加流畅

public class MainActivity extends AppCompatActivity {
    ProgressBar barTimer;
    CountDownTimer countDownTimer;
    TextView textTimer;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        barTimer = findViewById(R.id.barTimer);


       barTimer.setMax(1000);
        startTimer(10);

    }

    private void startTimer(final int minuti) {
        countDownTimer = new CountDownTimer(60 * minuti * 1000, 100) {
            @Override
            public void onTick(long leftTimeInMilliseconds) {

                long seconds = leftTimeInMilliseconds / 600;

                barTimer.setProgress((int)seconds);

            }
            @Override
            public void onFinish() {

            }
        }.start();

    }
    }
