我需要为正在执行的项目计步器,因此我遵循了本教程:http://blog.bawa.com/2013/11/create-your-own-simple-pedometer.html
不幸的是,即使遵循其中的每一行代码,它也不起作用。我的意思是,没有步骤被计算或检测到。不幸的是,我无法与本教程的创建者联系,因此需要尽快。任何人都不知道可能是什么问题?我缺少重要的东西吗?
这是代码:
private TextView textView;
private SensorManager mSensorManager;
private Sensor mStepCounterSensor;
private Sensor mStepDetectorSensor;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView)findViewById(R.id.textView);
mSensorManager = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
mStepCounterSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_STEP_COUNTER);
mStepDetectorSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_STEP_DETECTOR);
}
protected void onResume() {
super.onResume();
mSensorManager.registerListener(this, mStepCounterSensor, SensorManager.SENSOR_DELAY_FASTEST);
mSensorManager.registerListener(this, mStepDetectorSensor, SensorManager.SENSOR_DELAY_FASTEST);
}
protected void onStop() {
super.onStop();
mSensorManager.unregisterListener(this, mStepCounterSensor);
mSensorManager.unregisterListener(this, mStepDetectorSensor);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
// TODO Auto-generated method stub
}
@Override
public void onSensorChanged(SensorEvent event) {
Sensor sensor = event.sensor;
float[] values = event.values;
int value = -1;
if (values.length > 0) {
value = (int) values[0];
}
if (sensor.getType() == Sensor.TYPE_STEP_COUNTER) {
textView.setText(" Step Counter Detected : " + value);
} else if (sensor.getType() == Sensor.TYPE_STEP_DETECTOR) {
// For test only. Only allowed value is 1.0 i.e. for step taken
textView.setText(" Step Detector Detected : " + value);
}
}
最佳答案
Nexus 7没有内置的计步器传感器,这是您以前使用的代码所必需的。
请注意,博客文章的作者使用的是Nexus 5,它确实具有这种传感器。
关于java - 简单的Android计步器无法正常工作,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/23520814/
