如何在逆时针安卓系统中移动ProgressBar

import android.os.Bundle;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.widget.ProgressBar;

import java.util.Timer;
import java.util.TimerTask;

public class MainActivity extends AppCompatActivity {

    private ProgressBar progressBar;
    private int progressStatus = 0;
    private Handler handler = new Handler();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        progressBar = findViewById(R.id.progressBar);

        // 设置初始进度值
        progressBar.setProgress(0);

        // 创建一个计时器
        Timer timer = new Timer();

        // 创建一个计时器任务
        TimerTask timerTask = new TimerTask() {
            @Override
            public void run() {
                // 更新进度条的值
                progressStatus++;
                handler.post(new Runnable() {
                    @Override
                    public void run() {
                        progressBar.setProgress(progressStatus);
                    }
                });

                // 如果达到最大值，取消计时器
                if (progressStatus == 100) {
                    timer.cancel();
                }
            }
        };

        // 每隔一段时间执行计时器任务
        timer.schedule(timerTask, 0, 100);
    }
}
