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();

一个自定义背景和视图的祝酒词对我来说很管用。我在nexus 7平板电脑上测试了它，我注意到在循环过程中没有淡入淡出动画。实现如下:

public static void customToast(Context context, String message, int duration) {

    for (int i = 0; i < duration; i++) {
        Toast toast = new Toast(context);
        toast.setDuration(Toast.LENGTH_LONG);
        toast.setGravity(Gravity.CENTER, 0, 0);
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.toast_layout, null);
        TextView textViewToast = (TextView) view
                .findViewById(R.id.textViewToast);
        textViewToast.setText(message);
        toast.setView(view);
        toast.show();
    }

}

下面是上面代码中使用的自定义textview:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/textViewToast"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/fragment_background"
android:padding="8dp"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="@color/blue" />

@drawable/fragment_background正在使我的吐司有圆角，就像kitkat版本一样。您还可以在该文件中添加其他视图。任何改进和评论的修改都是鼓励的，因为我计划在我的live应用程序中实现这一点。

我知道我有点晚了，但我取了Regis_AG的答案，并将其包装在一个助手类中，它工作得很好。

public class Toaster {
  private static final int SHORT_TOAST_DURATION = 2000;

  private Toaster() {}

  public static void makeLongToast(String text, long durationInMillis) {
    final Toast t = Toast.makeText(App.context(), text, Toast.LENGTH_SHORT);
    t.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL, 0, 0);

    new CountDownTimer(Math.max(durationInMillis - SHORT_TOAST_DURATION, 1000), 1000) {
      @Override
      public void onFinish() {
        t.show();
      }

      @Override
      public void onTick(long millisUntilFinished) {
        t.show();
      }
    }.start();
  }
}

在你的应用代码中，就像这样做:

    Toaster.makeLongToast("Toasty!", 8000);

为此，我编写了一个辅助类。你可以在github上看到代码:https://github.com/quiqueqs/Toast-Expander/blob/master/src/com/thirtymatches/toasted/ToastedActivity.java

这是你如何在5秒(或5000毫秒)内显示祝酒词:

Toast aToast = Toast.makeText(this, "Hello World", Toast.LENGTH_SHORT);
ToastExpander.showFor(aToast, 5000);

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();
