Java:

LinearLayout sensoelayout;

Boolean b=boolean.true;

@Override

protected void OnCreate (Bundle savedinstancestate) {

Super.oncreate (savedinstancestate);

Setcontentview (r.layout.activity_my);

?

sensoelayout= (LinearLayout) Findviewbyid (r.id.root);

?

Sensormanager sm = (Sensormanager) getsystemservice (Context.sensor_service);

?

list<sensor> allsensors = sm.getsensorlist (Sensor.type_all);

?

int i=1;

for (Sensor s:allsensors)

{

?

TextView tv=new TextView (this);

Tv.setid (i);

Tv.settext (i + "Name:" + s.getname () + "\ n Vendor:" + s.getvendor () +

"\ n Type:" + s.gettype () +

"\ n maximumrange:" + s.getmaximumrange ()

+ "\ n Version:" + s.getversion () +

"\ n Power:" + s.getpower ()

);

?

?

Tv.settextsize (23);

?

if (b)

{

Tv.settextcolor (Color.green);

}

Else

{

Tv.settextcolor (color.red);

}

B=!b;

Sensoelayout.addview (TV);

i++;

}

The code above uses two sensor libraries:

Import Android.hardware.Sensor;

Import Android.hardware.SensorManager;
