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 : -

解决方法:
您的ints秒,分钟和小时等被视为资源. textView.setText()有两个签名,一个是String,一个是int来查找资源.这就是你得到错误的原因：
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)
你必须将它们转换为这样的String
String.valueOf(days);
更新
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();
}
}
