Java 如何在MainActivity内启动加速计活动

这是我的

SensorActivity

类，在

MainActivity

中声明。如何在

main活动

的

onCreate

方法中启动

加速计

传感器

public class SensorActivity extends Activity implements SensorEventListener{
    private final SensorManager mSensorManager;
    private final Sensor mAccelerometer;


    public SensorActivity() {
        mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
        mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    }

    protected void onResume() {
        super.onResume();
        mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);
    }

    protected void onPause() {
        super.onPause();
        mSensorManager.unregisterListener(this);
    }

    @Override
    public void onSensorChanged(SensorEvent sensorEvent) {

       //DO THINGS

    }

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

    }

您可以通过以下意图启动新活动：

Intent intent = new Intent(MainActivity.this, MainActivity.SensorActivity.class);
startActivity(intent);
