我有一个记录加速度计数据的应用程序，并在通过treshhold时发送短信。手机醒着时工作正常。我需要做什么，这也可以在手机锁定/睡眠时也这样做：
我有两个活动SendSMSActivity.java：
package com.example.sendsms;
import android.app.Activity;
import android.content.ContentResolver;
import android.content.Context;
import android.database.Cursor;
import android.hardware.Sensor;

import android.widget.SimpleCursorAdapter;
import android.widget.TextView;
import android.widget.Toast;
public class SendSMSActivity extends Activity implements SensorEventListener {

private SensorManager senSensorManager;
private Sensor senAccelerometer;
private long lastUpdate;
private float last_x, last_y, last_z;
//Contacts variable
AutoCompleteTextView emailText;
ContentResolver cr;
SimpleCursorAdapter emailAdapter;
protected void onResume() {
super.onResume();
senSensorManager.registerListener(this, senAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);
}
protected void onPause() {
super.onPause();
senSensorManager.unregisterListener(this);
}
@Override
public void onSensorChanged(SensorEvent sensorEvent) {
//To change body of implemented methods use File | Settings | File Templates.
Sensor mySensor = sensorEvent.sensor;
if (mySensor.getType() == Sensor.TYPE_ACCELEROMETER) {
float x = sensorEvent.values[0];
float y = sensorEvent.values[1];
float z = sensorEvent.values[2];
long curTime = System.currentTimeMillis();
// only allow one update every 100ms.
if ((curTime - lastUpdate) > 100) {
long diffTime = (curTime - lastUpdate);
lastUpdate = curTime;
float speed = Math.abs(x+y+z - last_x - last_y - last_z)/ diffTime * 10000;
TextView threshText = (TextView)findViewById(R.id.thresh);
if (speed > Float.parseFloat(threshText.getText().toString())) {
Toast.makeText(this, "shake detected w/ speed: " + speed, Toast.LENGTH_SHORT).show();
Toast.makeText(this, "shake detected w/ speed: " + speed, Toast.LENGTH_SHORT).show();
TextView resultText = (TextView)findViewById(R.id.xacc);
resultText.setText("shake detected w/ speed: " + speed);
sendit2();
}
last_x = x;
last_y = y;

}
}
}
