I have created a proximity service which performs basic on/off of screen depending on the sensor value. I needed to time these sensor changes so i used the following code
override fun onSensorChanged(event: SensorEvent) {
val distance = event.values[0]
val max = event.sensor.maximumRange
val startTime = System.currentTimeMillis()
if (distance < Math.min(max, 8.toFloat())) {
listener.onNear()
} else {
listener.onFar()
}
val endTime = System.currentTimeMillis()
System.out.println("That took " + (endTime - startTime) + " milliseconds")
}
I am getting the values in log cat but i need to print these on my app, my app activity is in another java class called settings activity. I have added a textview called "Time taken" how to push those values of (endTime-startTime) to this textview??? or should i have to use any other layout comonent?? My settings layout image
You need to set id of that TextView
and then bindview in java and after it you can set text into TextView
Your XML should have this widget
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
now in your java, bind this textview with id like
TextView tv=(TextView)findViewById(R.id.textView1);
now you have tv
object of TextView
that will help you to setText()
like
tv.setText("That took " + (endTime - startTime) + " milliseconds");
