我想在单击按钮时取消 countdountimer 的 onfinish 函数我执行 timer.cancel 但仍然调用 on finish。
running = false;
countDownTimer.cancel();
countDownTimer = null;
finish();
startActivity(i);
这是倒计时
private CountDownTimer createTimer() {
return new CountDownTimer(getIntent().getIntExtra("timer", 5460000),
1000) {
@SuppressLint("NewApi")
public void onTick(long millisUntilFinished) {
timer.setText("Section time: "
+ String.format(
Locale.ENGLISH,
"%d min, %d sec",
TimeUnit.MILLISECONDS
.toMinutes(millisUntilFinished),
TimeUnit.MILLISECONDS
.toSeconds(millisUntilFinished)
- TimeUnit.MINUTES
.toSeconds(TimeUnit.MILLISECONDS
.toMinutes(millisUntilFinished))));
timer_count = (int) millisUntilFinished;
}
public void onFinish() {
if (running) {
int random;
if (getIntent().getIntExtra("t_no", 0) < 20) {
i = new Intent(getApplicationContext(),
Practice_intruction.class);
i.putExtra("type", "Test");
Random r = new Random();
random = r.nextInt(MainActivity.vocab.size() - 11);
i.putExtra("q_no", random);
i.putExtra("t_no", 20);
i.putExtra("answers",
getIntent().getStringExtra("answers"));
countDownTimer.cancel();
countDownTimer = null;
running = false;
finish();
startActivity(i);
} else if (getIntent().getIntExtra("t_no", 0) < 40) {
i = new Intent(getApplicationContext(),
Practice_intruction.class);
i.putExtra("type", "Test");
Random r = new Random();
random = r.nextInt(MainActivity.listining.size() - 4);
i.putExtra("q_no", random);
i.putExtra("t_no", 40);

getIntent().getStringExtra("answers"));
countDownTimer.cancel();
countDownTimer = null;
running = false;
finish();
startActivity(i);
} else if (getIntent().getIntExtra("t_no", 0) < 50) {

countDownTimer.cancel();

这是我使用倒数计时器的 Activity 的一部分，除了这里我没有在任何地方使用它

最佳答案
似乎在任何情况下都会调用 finish()。但是，如果您在取消之前将 running 设置为 false，则您的 finish() 方法不会执行任何操作，因此应该没问题。
running = false;
countdownTimer.cancel();
关于android - 倒计时 onfinish();取消后仍然调用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36688159/
