Question

我需要在最初的60秒内启动计时器，但是当我按下按钮时，设置5秒或者只是取消但是它不起作用：

 temp = new CountDownTimer(60000, 1000) {
        Button acabar= (Button) findViewById(R.id.button_abandonar);
         public void onTick(long millisUntilFinished) {

             int seg = (int) (millisUntilFinished /1000);
             if(seg<10){
                 veces.setText("0" + seg);
             }else{
                 veces.setText("" + seg);
             }
         }

         public void onFinish() {
              //something

         }

      };

    if(v.getId()==R.id.view_pulsar){
        //Here I start temp and I do more things, but I don't show this code because is not relevant to this problem
    }else if(v.getId()==R.id.button_abandonar){
        temp.cancel();
        //temp = null;
        //here set 5 seconds, not 60 second I think cancel and restart it

}

我只是修理它，我在方法onclick上初始化了计时器，它同时有各种计时器！

什么笨拙！

看不到你的temp.start（）;也许你应该叫它

编辑reff http://developer.android.com/reference/android/os/CountDownTimer.html

 new CountDownTimer(30000, 1000) {

     public void onTick(long millisUntilFinished) {
         mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
     }

     public void onFinish() {
         mTextField.setText("done!");
     }
  }.start();

为什么CountDownTimer不取消？
