如何在多个SpannableString实例上显示不同的toast消息？

// 创建多个SpannableString实例
SpannableString message1 = new SpannableString("Toast Message 1");
SpannableString message2 = new SpannableString("Toast Message 2");
SpannableString message3 = new SpannableString("Toast Message 3");

// 设置SpannableString的样式，例如设置字体颜色、字体大小等
message1.setSpan(new ForegroundColorSpan(Color.RED), 0, message1.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
message2.setSpan(new StyleSpan(Typeface.BOLD), 0, message2.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
message3.setSpan(new UnderlineSpan(), 0, message3.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

// 创建Toast实例
Toast toast = Toast.makeText(getApplicationContext(), "", Toast.LENGTH_SHORT);

// 设置Toast的视图为SpannableString实例
TextView toastView = new TextView(getApplicationContext());
toastView.setText(message1);
toast.setView(toastView);

// 显示Toast消息
toast.show();

// 更改Toast的视图为其他SpannableString实例
toastView.setText(message2);
toast.show();

// 更改Toast的视图为另一个SpannableString实例
toastView.setText(message3);
toast.show();
