我正在尝试构建一个应用程序,我需要使用加速度计。使用传感器模拟器,加速度计工作正常,但是当我制作 apk 时,加速度计的输出不起作用。我使用的是三星 Exibit 4g XII,这个设备有加速度计
public class AcelerometerImp extends Activity implements SensorEventListener {
StringBuilder builder;
TextView textView;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
textView = new TextView(this);
setContentView(textView);
SensorManager manager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
textView.setText( (manager.getSensorList( Sensor.TYPE_ACCELEROMETER ).size() == 0)
? "No hay acelerometro" : manager.getSensorList( Sensor.TYPE_ACCELEROMETER ).get(0).toString() );
}
@Override
public void onSensorChanged (SensorEvent event){
builder.setLength(0);
builder.append("x: " + event.values[0] + ", y: " + event.values[1] + ", z: " + event.values[2]);
textView.setText(builder.toString());
}
@Override
public void onAccuracyChanged (Sensor sensor, int accuracy){
}
}
