I want to set this textview:
<TextView
android:id="@+id/timer"
android:layout_width="100dp"
android:layout_height="30dp"
android:layout_above="@+id/directions"/>
To be a timer. So the text should be a timer going like 0:30 then 0:29 ... for 30 seconds. Once timer is 0:00, I can call another method; I can print out "try again" and restart timer.
int time=30;
TextView textTimer = (TextView)findViewById(R.id.timer);
new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
textTimer.setText("0:"+checkDigit(time));
time--;
}
public void onFinish() {
textTimer.setText("try again");
}
}.start();
public String checkDigit(int number) {
return number <= 9 ? "0" + number : String.valueOf(number);
}

Try code:
import java.util.Timer;
import java.util.TimerTask;
import android.os.Bundle;
import android.widget.TextView;
import android.app.Activity;
public class MainActivity extends Activity {
public int seconds = 60;
public int minutes = 10;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Declare the timer
Timer t = new Timer();
//Set the schedule function and rate
t.scheduleAtFixedRate(new TimerTask() {
@Override
public void run() {
runOnUiThread(new Runnable() {
@Override
public void run() {
TextView tv = (TextView) findViewById(R.id.main_timer_text);
tv.setText(String.valueOf(minutes)+":"+String.valueOf(seconds));
seconds -= 1;
if(seconds == 0)
{
tv.setText(String.valueOf(minutes)+":"+String.valueOf(seconds));
seconds=60;
minutes=minutes-1;
}
}
});
}
}, 0, 1000);
}
}
long MillisecondTime, TimeBuff, UpdateTime = 0L;
int Seconds, Minutes, MilliSeconds;
TextView textViewTimer = findViewById(R.id.timerTextView);
public void startTimer() {
new CountDownTimer(180000, 1000) {
public void onTick(long millisUntilFinished) {
MillisecondTime = millisUntilFinished;
UpdateTime = TimeBuff + MillisecondTime;
Seconds = (int) (UpdateTime / 1000);
Minutes = Seconds / 60;
Seconds = Seconds % 60;
MilliSeconds = (int) (UpdateTime % 1000);
textViewTimer.setText("0" + Minutes + ":"
+ String.format("%02d", Seconds) + ":"
+ String.format("",MilliSeconds));
}
public void onFinish() {
textViewTimer.setText("Done!");
}
}.start();
}
Call startTimer() method and this will set timer to textView for e.g. start time 02:59:00
public void settimer() {
new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
long remainedSecs = millisUntilFinished / 1000;
forgotpasswordBinding.txtotptime.setText("" + (remainedSecs / 60) + ":" + (remainedSecs % 60));
}
public void onFinish() {
forgotpasswordBinding.txtotptime.setText("Resend");
forgotpasswordBinding.txtotptime.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
settimer();
}
});
}
}.start();
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Timer t = new Timer(); //declare the timer
t.scheduleAtFixedRate(new TimerTask() { //Set the schedule function and rate
@Override
public void run() {
runOnUiThread(new Runnable() {
@Override
public void run() {
TextView mRefreshTime = (TextView) findViewById(R.id.screenStatusTvTime);
mRefreshTime.setText(String.format("%dh%02d'%02d\"", minutes/60, minutes%60, seconds));
if (++seconds == 60) {
seconds = 0;
minutes++;
}
}
});
}
}, 0L, 1000L);
timer will set for 3min like "2:59"
private int time=60,n=2;
textTimer=findViewById(R.id.timer);
// textview
new CountDownTimer(180000, 1000) {
public void onTick(long millisUntilFinished)
{
if(time==0)
{
n--;
time=60;
}
textTimer.setText( n +":" + checkdigit(time));
time--;
}
public void onFinish() {
}
}.start();
public String checkdigit(int number)
{
return number <= 9 ? "0" + number : String.valueOf(number);
}
