    <p>So I'm looking for a way to get the current value of the Light Sensor (in Lux obviously) on a button press. Here is the code I'm using to implement control of the light sensor</p> <pre><code>public class SensorActivity extends Activity implements SensorEventListener { private final SensorManager mSensorManager; private final Sensor mLight; int minLux = 0; int currentLux = 0; int maxLux; public SensorActivity() { mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE); mLight = mSensorManager.getDefaultSensor(Sensor.TYPE_LIGHT); } protected void onResume() { super.onResume(); mSensorManager.registerListener((SensorEventListener) this, mLight, SensorManager.SENSOR_DELAY_NORMAL); } protected void onPause() { super.onPause(); mSensorManager.unregisterListener((SensorListener) this); } public void onAccuracyChanged(Sensor sensor, int accuracy) { if(sensor.getType() == Sensor.TYPE_LIGHT) { } } public void onSensorChanged(SensorEvent event) { if( event.sensor.getType() == Sensor.TYPE_LIGHT) { } } } </code></pre> <p>I also have this code making the button to call a function</p> <pre><code>&lt;Button android:layout_width="122px" android:id="@+id/widget35" android:text="Start" android:layout_height="wrap_content" android:layout_x="112dp" android:layout_y="249dp" android:onClick="onButtonDown"&gt;&lt;/Button&gt; </code></pre> <p>How would I get the current lux value while the app is running in the background, and how would I get and store the current lux value on button press into <code>int maxLux;</code>?</p>

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.
