我正在开发一个指南针应用程序,但遇到了传感器类型 Sensor.TYPE_ORIENTATION 已弃用的问题,不知道该怎么解决。请问能否提供一些帮助?这是我的代码和我所做的事情。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_compass);
//
// TextView that will tell the user what degree is he heading
tvHeading = (TextView) findViewById(R.id.tvHeading);
// initialize your android device sensor capabilities
mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
}
@Override
protected void onResume() {
super.onResume();
// for the system's orientation sensor registered listeners
mSensorManager.registerListener(this, **mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION),
SensorManager.SENSOR_DELAY_GAME);**
}
@Override
protected void onPause() {
super.onPause();
// to stop the listener and save battery
mSensorManager.unregisterListener(this);
}
@Override
public void onSensorChanged(SensorEvent event) {
// get the angle around the z-axis rotated
float degree = Math.round(event.values[0]);
tvHeading.setText("Heading: " + Float.toString(degree) + " degrees");
// create a rotation animation (reverse turn degree degrees)
RotateAnimation ra = new RotateAnimation(
currentDegree,
-degree,
Animation.RELATIVE_TO_SELF, 0.5f,
Animation.RELATIVE_TO_SELF,
0.5f);
// how long the animation will take place
ra.setDuration(210);
// set the animation after the end of the reservation status
ra.setFillAfter(true);
// Start the animation
image.startAnimation(ra);
currentDegree = -degree;
}
这个想法是在代码执行后,根据指南针检测到的角度旋转图像。
