安卓 : How to repeat a Toast every second

Question

我正在为倒数计时器使用 toast，所以 toast 应该每秒更改它的文本。我用它来显示 toast 恰好 1 秒，但我希望 toast 自己重复。希望我能让你明白。

 toast =    Toast.makeText(getApplicationContext(), text.getText().toString(), Toast.LENGTH_SHORT);             toast.show();
Handler handler = new Handler();
    handler.postDelayed 
               (new Runnable() {

              @Override
                 public void run() {
                            toast.cancel();
            }
        }, 1000);

这将在整整一秒内每秒显示一个新的 toast。

    int count = 100; //Declare as inatance variable

    Timer timer = new Timer();
    timer.schedule(new TimerTask() {

        @Override
        public void run() {
            runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    final Toast toast = Toast.makeText(
                            getApplicationContext(), --count + "",
                            Toast.LENGTH_SHORT);
                    toast.show();
                    Handler handler = new Handler();
                    handler.postDelayed(new Runnable() {

                        @Override
                        public void run() {
                            toast.cancel();
                        }
                    }, 1000);

                }
            });
        }
    }, 0, 1000);
