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);
}

吐司持续时间可以使用专门运行吐司的线程来破解。这是有效的(运行吐司10秒，修改睡眠和ctr到你的喜欢):

final Toast toast = Toast.makeText(this, "Your Message", Toast.LENGTH_LONG);

Thread t = new Thread(){
    public void run(){
          int ctr = 0;
          try{
               while( ctr<10 ){
                    toast.show();
                    sleep(1000);
                    ctr++;
               }
          } catch (Exception e) {
               Log.e("Error", "", e);
          }
     }
 };
 t.start();

为什么要吃吐司，当你可以拥有整个Snackbar: https://developer.android.com/reference/android/support/design/widget/Snackbar.html

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。

计划一个倒计时，直到将来的某个时间，并在此过程中定期通知。在文本框中显示30秒倒计时的例子:

     new CountDownTimer(30000, 1000) {

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

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

下面是我用上面的代码创建的一个自定义Toast类:

import android.content.Context;
import android.os.CountDownTimer;
import android.widget.Toast;

public class CustomToast extends Toast {
    int mDuration;
    boolean mShowing = false;
    public CustomToast(Context context) {
        super(context);
        mDuration = 2;
    }


    /**
     * Set the time to show the toast for (in seconds) 
     * @param seconds Seconds to display the toast
     */
    @Override
    public void setDuration(int seconds) {
        super.setDuration(LENGTH_SHORT);
        if(seconds < 2) seconds = 2; //Minimum
        mDuration = seconds;
    }

    /**
     * Show the toast for the given time 
     */
    @Override
    public void show() {
        super.show();

        if(mShowing) return;

        mShowing = true;
        final Toast thisToast = this;
        new CountDownTimer((mDuration-2)*1000, 1000)
        {
            public void onTick(long millisUntilFinished) {thisToast.show();}
            public void onFinish() {thisToast.show(); mShowing = false;}

        }.start();  
    }
}
