我可以用吐司的CountDownTimer [英] Can I use a Toast for the CountDownTimer

问题描述

我想用CountdownTimer内敬酒，但问题是吐司计数太慢，当新的活动恒星的吐司没有完成counting.I知道它是更容易使用一个TextView，但我只是想知道这是possible.Any想法？

  @覆盖
公共无效的onClick（查看为arg0）{
    // TODO自动生成方法存根
    如果（Edt.getText（）。的toString（）。长度（）== 0）{
        Toast.makeText（MainActivity.this，什么，兄弟？Toast.LENGTH_LONG）.show（）;
    }否则如果（sec.getText（）。的toString（）。长度（）== 0）{
        Toast.makeText（MainActivity.this，当，兄弟？Toast.LENGTH_LONG）.show（）;    }其他{
    事件=新的String（Edt.getText（）的toString（））;
    最终诠释时间=的Integer.parseInt（sec.getText（）的toString（））;
    意图敏=新意图（MainActivity.this，Receiver.class）;    myInt.putExtra（钥匙，事件）;
    的PendingIntent的PendingIntent = PendingIntent.getActivity（MainActivity.this，2敏，PendingIntent.FLAG_CANCEL_CURRENT）;
    AlarmManager AM =（AlarmManager）getSystemService（ALARM_SERVICE）;
    am.set（AlarmManager.RTC_WAKEUP，System.currentTimeMillis的（）+（时间* 1000），的PendingIntent）;
    新CountDownTimer（时间* 1000，1000）{         公共无效onTick（长millisUntilFinished）{            Toast.makeText（MainActivity.this，报警开始于+ + millisUntilFinished / 1000 +秒，Toast.LENGTH_SHORT）.show（）;         }         公共无效onFinish（）{
         }
      }。开始（）;
}
 

解决方案

如果你的意思是他们堆叠起来造成的延迟，那么你应该呈现出新之前取消了之前敬酒。

如果你想要的东西更看中你可以尝试使用PopupWindow而不是要显示倒计时，有你有布局等更自由。

I want to use a Toast inside the CountdownTimer, but the problem is the Toast counts too slow and when the new Activity stars the Toast isn't finished counting.I know it is easier to use a TextView but I just wanted to know if it is possible.Any ideas?

@Override
public void onClick(View arg0) {
    // TODO Auto-generated method stub
    if(Edt.getText().toString().length() == 0){
        Toast.makeText(MainActivity.this,"What, bro?",Toast.LENGTH_LONG).show();
    }else if(sec.getText().toString().length() == 0){
        Toast.makeText(MainActivity.this,"When, bro?",Toast.LENGTH_LONG).show();

    }else{
    Event=new String(Edt.getText().toString());
    final int time = Integer.parseInt(sec.getText().toString());


    Intent myInt = new Intent(MainActivity.this,Receiver.class);

    myInt.putExtra("key",Event);
    PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this,2,myInt,PendingIntent.FLAG_CANCEL_CURRENT);
    AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
    am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+(time*1000),pendingIntent);


    new CountDownTimer(time*1000, 1000) {

         public void onTick(long millisUntilFinished) {

            Toast.makeText(MainActivity.this,"Alarm starts in"+ +millisUntilFinished/1000 + "seconds",Toast.LENGTH_SHORT).show();

         }

         public void onFinish() {


         }
      }.start();


}

解决方案

If you mean that they stack up causing a delay then you should cancel the prior toast before showing a new one.

If you want something more fancy you could try using a PopupWindow instead to show the countdown, there you have more freedom for layout etc.
