We have to get a Sensor's Object from SensorManager.
Set the type "Sensor.TYPE_STEP_DETECTOR".
[java] view plain copy
public class StepCounterActivity extends Activity {
private SensorManager mSensorManager;
private Sensor mStepSensor;
private TextView mTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTextView = (TextView) findViewById(R.id.text_step);
mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
mStepSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_STEP_DETECTOR);
}
protected void onResume() {
super.onResume();
mSensorManager.registerListener(mSensorEventListener, mStepSensor,
SensorManager.SENSOR_DELAY_NORMAL);
}
protected void onPause() {
super.onPause();
mSensorManager.unregisterListener(mSensorEventListener);
}
Create a SensorListener
We can get a trigger from onSensorChanged.
[java] view plain copy
private SensorEventListener mSensorEventListener = new SensorEventListener() {
private int mStep;
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}
@Override
public void onSensorChanged(SensorEvent event) {
if (event.values[0] == 1.0f) {
mStep++;
}
mTextView.setText(Integer.toString(mStep));
}
};
