I am trying to create an android application to find the phone moving direction with Text to speech.There is a lot of problems with this.ie,it working some what,and i am not getting accurate movement.this is my code
@Override
public void onSensorChanged(SensorEvent event) {
Sensor sensor = event.sensor;
float [] values = event.values;
synchronized (this) {
Log.d(tag, "onSensorChanged: " + sensor + ", x: " +
values[0] + ", y: " + values[1] + ", z: " + values[2]);
if (sensor.getType() == Sensor.TYPE_ACCELEROMETER ) {
x.setText("x"+ values[0]);
y.setText("y"+ values[1]);
z.setText("z"+ values[2]);
xa=(int)values[0];// this part of code is only test to see int x and y on Activity
ya=(int)values[1];
ball.scrollBy(xa, ya);
a=Integer.toString(xa);
b=Integer.toString(ya);
ball.scrollBy(xa, ya);
xat.setText(a);
yat.setText(b);
if (trigL || trigD || trigR || trigU ) {
int ttt = TextToSpeech.QUEUE_FLUSH;
final long ACCEL_SENSOR_DELAY = 100;
long lastAccelSensorChange = 0;
long now = System.currentTimeMillis();
if ((now-ACCEL_SENSOR_DELAY) > lastAccelSensorChange) {
lastAccelSensorChange = now;
ttt = TextToSpeech.QUEUE_FLUSH;
sensore.registerListener(MainActivity.this, accelerometer,
trigL = false;
trigR = false;
trigU = false;
trigD = false;
}
}
if (values[0] < -6) {
trigL = true;
if(tts.isSpeaking())
{
return;
}
else
tts.speak("Move Left", TextToSpeech.QUEUE_FLUSH, null);
values[0]=0;
values[1]=0;
return;
} else if (values[0] > 6) {
trigR = true;
if(tts.isSpeaking())
{
return;
}
else
tts.speak("Move Right", TextToSpeech.QUEUE_FLUSH, null);
values[0]=0;
values[1]=0;
return;
}
else if (values[1] < -6) {
trigD = true;
if(tts.isSpeaking())
{
return;
}
else
tts.speak("Move Down", TextToSpeech.QUEUE_FLUSH, null);
values[1]=0;
values[0]=0;
return;
} else if (values[1] > 6) {
trigU = true;
if(tts.isSpeaking())
{
return;
}
else
tts.speak("Move Up", TextToSpeech.QUEUE_FLUSH, null);
values[1]=0;
values[0]=0;
return;
}
}
}
}
I am searching for last 2 weeks. Any suggestions can be help full for me.
