每天重置步计数器值android

Question

我做了这个Android应用程序，它计算足迹并且运行良好，但它只能重置设备重启时的步骤。我希望它将计算的足迹存储在SharedPreferences首选项中。然后每天将其重置为零，但我不知道如何继续。通过运行reset（）函数，它只将可视步骤设置为零。

public class MainActivity extends AppCompatActivity implements  SensorEventListener {
SensorManager sensorManager;
TextView tv_steps;
boolean running = false;
SharedPreferences prefs = null;
SharedPreferences.Editor editor;
int steps;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    tv_steps = (TextView) findViewById(R.id.tv_steps);
    sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
    prefs = getApplicationContext().getSharedPreferences("MY_PREFS", MODE_PRIVATE);
    editor = prefs.edit();

}

@Override
protected void onResume(){
    super.onResume();
    running = true;
    Sensor countSensor = sensorManager.getDefaultSensor(Sensor.TYPE_STEP_COUNTER);
    if(countSensor != null){
        sensorManager.registerListener(this, countSensor, SensorManager.SENSOR_DELAY_UI);
    }
    else {
        Toast.makeText(this, "Sensor not found!", Toast.LENGTH_SHORT).show();
    }
}

@Override
protected void onPause(){
    super.onPause();
    running = false;
    sensorManager.unregisterListener(this);
    // unregistering register listener hardware counter is disabled
}

@Override
public void onSensorChanged(SensorEvent event) {
     if(running){
       steps = (int) event.values[0];
       editor.putInt("steps", steps);
       editor.commit();
       //  resetStepCount();
       tv_steps.setText(String.valueOf(prefs.getInt("steps", steps)));

     }
}

private void resetStepCount() {
    //   reset every 24 hours.
    editor.clear();
    steps = 0;
    editor.putInt("steps", steps);
    editor.commit();

}

@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {

}
}
