    <requestFocus />

这是我的活动

ProgressBar editProgressBar;
SeekBar seekBar;
TextView tvProgress;
TextView textView2;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_progress);

   editProgressBar = (ProgressBar) findViewById(R.id.progressBar1);
   seekBar = (SeekBar) findViewById(R.id.seekBar1);
   seekBar.setOnSeekBarChangeListener(this);
   tvProgress = (TextView) findViewById(R.id.tvProgress); 
   textView2 = (TextView) findViewById(R.id.textView2); 

    setMaxProgress();
    setCurrentProgress();
}

@Override
protected void onResume() {
    setMaxProgress();
    setCurrentProgress();
    super.onResume();
}

private void setCurrentProgress() {
    SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(this);
    int p = sharedPref.getInt("prefs_progress", -1);
    long time = sharedPref.getLong("prefs_progress_time", -1);
    if (p != -1) {
        Calendar now = Calendar.getInstance();
        Calendar pTime = Calendar.getInstance();
        pTime.setTimeInMillis(time);
        if (now.get(Calendar.DAY_OF_WEEK) == pTime.get(Calendar.DAY_OF_WEEK)) {
            editProgressBar.setProgress(p);
            seekBar.setMax(editProgressBar.getMax() - p);
        }
    }
}

private void setMaxProgress() {
    SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(this);
    Float l = sharedPref.getFloat("prefs_liters", -1);
    if (l > -1) {
        int ml = (int) (l * 1000);
        editProgressBar.setMax(ml);
        seekBar.setMax(ml);
        tvProgress.setText(0 + "");
    }

}

public void onSaveButtonClicked(View view) {
    int p = seekBar.getProgress() + editProgressBar.getProgress();
    editProgressBar.setProgress(p);
    seekBar.setProgress(0);
    seekBar.setMax(editProgressBar.getMax() - p);

    SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(this);
    SharedPreferences.Editor editor = sharedPref.edit();
    editor.putInt("prefs_progress", p);
    editor.putLong("prefs_progress_time", new Date().getTime());
    editor.commit();
}


@Override
public void onProgressChanged(SeekBar seekBar, int progress,
        boolean fromUser) {
    tvProgress.setText(progress + "");
}

@Override
public void onStartTrackingTouch(SeekBar seekBar) {
    // TODO Auto-generated method stub

}

@Override
public void onStopTrackingTouch(SeekBar seekBar) {
    // TODO Auto-generated method stub

}

}

尝试添加此..先使 ml 全局变量

if (now.get(Calendar.DAY_OF_WEEK) == pTime.get(Calendar.DAY_OF_WEEK)) {
    editProgressBar.setProgress(p);
    seekBar.setMax(editProgressBar.getMax() - p);

    new Thread(new Runnable() {
    @Override
        public void run() {
            // TODO Auto-generated method stub
            try{
                while(p<ml){
                    Thread.sleep(1000); // You can removed this sleep line, if
                                //your update(change of value of p) takes time.
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            // TODO Auto-generated method stub
                            tvProgress.setText(String.valueOf(p));
                        }
                    });
                }
            }
            catch(Exception e){
        // handle exception     
            }
        }
    }).start();
}

textView当前进度在progressbar下面
