Re: [android-developers] Re: how to create a custom gauge in android
hi bob,
am working actuallly on an application like the ADK2011
so mainly my app communicates with a board (like arduino ADK) and get the
temperature value via USB to be displayed
in mu custom gauge
thank you :)
2013/4/18 bob b...@coolfone.comze.com
Apparently, the Nexus 7 has no temperature sensor according to this method:
private void attachToSensor() {
SensorManager sensorManager = getSensorManager();
ListSensor sensors =
sensorManager.getSensorList(Sensor.TYPE_TEMPERATURE);
if (sensors.size() 0) {
Sensor sensor = sensors.get(0);
sensorManager.registerListener(this, sensor,
SensorManager.SENSOR_DELAY_FASTEST, handler);
} else {
Log.e(TAG, No temperature sensor found);
}
}
Thanks.

For some reason, that thermometer example doesn't seem to work right:

Both projects are very simple, but they demonstrate quite well how to
create a custom view similar to the one you apparently want.

Break the needle off of that image and put it in it's own image. Then use this function in *Canvas*: final void *rotate*(float degrees, float px, float py) Also, you will call *drawBitmap* in the Canvas class. Of course, you will want to *save()* and *restore()* the matrices before and after the rotation. Thanks.

Re: [android-developers] Re: how to create a custom gauge in android
If you don't use *save*() and *restore*() and something gets drawn after your needle, it will also be rotated just as the needle was rotated. So you would probably use something like this: *canvas.save();* canvas.rotate(45, 100, 100); canvas.drawBitmap(…); *canvas.restore();* Thanks.
