Creating a Timer which shows time left for an event in seconds , minutes , hours , days
Hello I am trying to create a timer wherein it will take the date and time of the event that will happen and convert it into milliseconds and also it will take current time and then subtract the current time from the event time and will calculate the hour minutes seconds and days from it. What I want to do is display those values in a textview but as and when I try and set it in textview it stops working and gives error : -

Answer
Your ints seconds, minutes and hours and so on are treated as resources. textView.setText() has two signatures, one takes a String, one an int to look up a resource. That's why you get the error :
Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x38
03-25 17:06:03.166: E/AndroidRuntime(993): at android.content.res.Resources.getText(Resources.java:229)
You have to convert them to a String like this
String.valueOf(days);
Update
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final TextView tv = new TextView(this);
setContentView(tv);
int hoursToGo = 0;
int minutesToGo = 0;
int secondsToGo = 30;
int millisToGo = secondsToGo*1000+minutesToGo*1000*60+hoursToGo*1000*60*60;
new CountDownTimer(millisToGo,1000) {
@Override
public void onTick(long millis) {
int seconds = (int) (millis / 1000) % 60 ;
int minutes = (int) ((millis / (1000*60)) % 60);
int hours = (int) ((millis / (1000*60*60)) % 24);
String text = String.format("%02d hours, %02d minutes, %02d seconds",hours,minutes,seconds);
tv.setText(text);
}
@Override
public void onFinish() {
tv.setText("Kabooom");
}
}.start();
}
}
