I'm using eclipse + Android SDK on ubuntu.
I would like to print the name of a sensor type device, there a A LOT OF THEM and i want to do it automatically.
If i use a
Log.d("SENSORTYPE","Type: " + tempSensor.getType())
I print the (int) type, but i would like the name whom use the enum.
How could i do that?
Thants in advance.
For enumerations, you can obtain an array of all the constants and loop over them very easily using code such as this:
for(YourEnum value: YourEnum.values()){
System.out.println("name="+value.name());
}
However, the Sensor class you link to isn't an enumeration, but contains a list of constants. There's no way to programatically loop over that list like an enumeration without specifying all the constants names.
However, you can create a static lookup that maps the ints to the String value you want to use, for example
Map<Integer,String> lookup = new HashMap<Integer,String>();
lookup.put(TYPE_ACCELEROMETER,"Accelerometer");
//Code a put for each TYPE, with the string you want to use as the name
You can use this like this:
Log.d("SENSORTYPE","Type: " + lookup.get(tempSensor.getType()));
This approach does mean you still have to write out each constant and update the list if the constants change, but you only have to do it once. It'd be a good idea to wrap the lookup in some kind of helper method or class depending on how widely you want to reuse it.
