Body
I'm still learning Android Development so sorry if this question seems stupid but I'm trying to obtain accelerometer data from the Phone for a limited time only. The goal is for the x-coordinate values from the sensor to be recorded only for about 3 seconds after a button is clicked. <pre><code>public class AccelerometerTestingActivity extends Activity implements SensorEventListener { private SensorManager sensorManager; float x_event[]; @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.main); sensorManager=(SensorManager)getSystemService(SENSOR_SERVICE); // add listener. The listener will be HelloAndroid (this) class sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_GAME); } public void onAccuracyChanged(Sensor sensor,int accuracy){ } public void onSensorChanged(SensorEvent event){ // check sensor type if(event.sensor.getType()==Sensor.TYPE_ACCELEROMETER){ // assign directions float x=event.values[0]; x_event=addArrayElement(x_event,x); } } private float[] addArrayElement(float[] currentArray, float x) { // TODO Auto-generated method stub float newArray[] = new float[currentArray.length+1]; int i= 0; for(i=0;i<currentArray.length;i++) { newArray[i] = currentArray[i]; } newArray[i+1]=x; return newArray; } </code></pre> So x_event is an array filled with the X position of the Accelerometer periodically every SENSOR_DELAY_GAME. The thing is, this code records all values while activity is running. What I would like is for this array to be filled only from the time a button is clicked, and filled only for x seconds (haven't decided on the value of x yet). After that the array would be passed to another function for analysis. I just don't understand how to limit the Listener in time. Thank you for your help.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
