Hello,
I tried to update my mapactivity with toast as the sensor data
changes.
However, my first Toast appears and it never change despite detecting
changes in sensor values.
What could be the reason?
Below is the snippet of my SensorListener:
Can someone please give me some advices! Thanks!
private final SensorListener mListener = new SensorListener()
{
public void onSensorChanged(int sensor, float[] values)
{
if(-values[0] < 0 && -values[0] > -1){
Toast.makeText(getApplicationContext(),
walkForward,
Toast.LENGTH_SHORT).show();
}else if(-values[0] < 1 && -values[0] > -90){
Toast.makeText(getApplicationContext(),
walkForward,
Toast.LENGTH_SHORT).show();
}else if(-values[0] < -90 && -values[0] > -91){
Toast.makeText(getApplicationContext(), right,
Toast.LENGTH_SHORT).show();
}else if(-values[0] < -91 && -values[0] > -180){
Toast.makeText(getApplicationContext(),
walkBack,
Toast.LENGTH_SHORT).show();
}else if(-values[0] < -180 && -values[0] > -181){
Toast.makeText(getApplicationContext(),
walkBack,
Toast.LENGTH_SHORT).show();
}else if(-values[0] < -181 && -values[0] > -270){
Toast.makeText(getApplicationContext(),
walkBack,
Toast.LENGTH_SHORT).show();
}else if(-values[0] < -270 && -values[0] > -271){
Toast.makeText(getApplicationContext(), left,
Toast.LENGTH_SHORT).show();
}else if(-values[0] < -271 && -values[0] > -360){
Toast.makeText(getApplicationContext(),
walkForward,
Toast.LENGTH_SHORT).show();
}
if (Config.LOGD) {
Log.d("", "sensorChanged (" + values[0] + ", " +
values[1] + ", " + values[2] + ")");
}
if(overlay!= null) overlay.setValue(values);
map.invalidate();
}
public void onAccuracyChanged(int sensor, int accuracy){}
};
