private Toast mToastToShow;
  public void showToast(View view) {
 // Set the toast and duration
 int toastDurationInMilliSeconds = 10000;
 mToastToShow = Toast.makeText(this, "Hello world, I am a toast.",  Toast.LENGTH_LONG);

 // Set the countdown to display the toast
 CountDownTimer toastCountDown;
 toastCountDown = new CountDownTimer(toastDurationInMilliSeconds, 1000 /*Tick duration*/) {
  public void onTick(long millisUntilFinished) {
     mToastToShow.show();
  }
  public void onFinish() {
     mToastToShow.cancel();
     }
    };

    // Show the toast and starts the countdown
     mToastToShow.show();
     toastCountDown.start();
      }

在所有可用的解决方案都失败后，我最终使用递归解决了问题。

代码:

//Recursive function, pass duration in seconds
public void showToast(int duration) {
    if (duration <= 0)
        return;

    Toast.makeText(this, "Hello, it's a toast", Toast.LENGTH_LONG).show();
    Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            showToast(duration-1);
        }
    }, 1000);
}

你可能想试试:

for (int i=0; i < 2; i++)
{
      Toast.makeText(this, "blah", Toast.LENGTH_LONG).show();
}

使时间加倍。如果你指定3而不是2，它会使时间增加三倍等等。

简单地使用SuperToast在任何情况下都可以做出优雅的吐司。让你的吐司颜色鲜艳。编辑你的字体颜色和大小。希望这对你来说都是一体的。

使用Crouton，这是一个非常灵活的吐司库。

油煎面包块

你可以像烤面包一样使用它:

Crouton.makeText(context, "YOUR_MESSAGE", Style.INFO);

或者你甚至可以更深入一点，自定义更多，比如将时间设置为无限!例如，在这里我想显示一个toast消息，直到用户通过点击它来确认它。

private static void showMessage(final Activity context, MessageType type, String header, String message) {
    View v = context.getLayoutInflater().inflate(R.layout.toast_layout, null);
    TextView headerTv = (TextView) v.findViewById(R.id.toastHeader);
    headerTv.setText(header);
    TextView messageTv = (TextView) v.findViewById(R.id.toastMessage);
    messageTv.setText(message);
    ImageView toastIcon = (ImageView) v.findViewById(R.id.toastIcon);

    final Crouton crouton = getCrouton(context, v);
    v.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Crouton.hide(crouton);
        }
    });

    crouton.show();
}

private static Crouton getCrouton(final Activity context, View v) {
    Crouton crouton = Crouton.make(context, v);
    crouton.setConfiguration(new Configuration.Builder().setDuration(Configuration.DURATION_INFINITE).build());
    return crouton;
}

自定义布局，将膨胀为吐司。
