Question

是否可以在Toast中使用按钮？

理论上，是的，因为您可以使用XML中的布局构建自定义Toast，但我尝试在其中放置一个按钮，但无法让它注册单击。有没有人设法做那样的事情？

Answer 1

无法点击敬酒。无法在Toast消息中捕获单击。您需要为此构建一个对话框。查看Creating Dialogs了解更多信息。

Toast类上的API声明toast永远不会获得焦点，因为toast不是视图，所以没有onClick消息。我认为因此也不能点击Toast的孩子。

Answer 2

吐司不能包含按钮。除了果冻豆中的gmail应用程序和图库应用程序都有一个包含按钮的半烤面包，Google就是这样做的

我想这可以回答你的问题。

Answer 3

Snippet显示了自定义Toast的实现：

Header

具有与原始Toast类
可以用作Dialog（具有Gmail应用等可点击按钮）
有可能在length

millis

有可能设置显示和取消动画
仅使用已初始化的Activity

目前的限制：

不支持屏幕方向更改

用法：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //...

    View toastView = new View(getBaseContext());
    //init your toast view

    ActivityToast toast = new ActivityToast(this, toastView);

    //set toast Gravity ( Gravity.BOTTOM | Gravity.FILL_HORIZONTAL by default)
    toast.setGravity(Gravity.CENTER);

    toast.setLength(10000); //set toast show duration to 10 seconds (2 seconds by default)

    Animation showAnim; // init animation
    Animation.AnimationListener showAnimListener; //init anim listener
    toast.setShowAnimation(showAnim);
    toast.setShowAnimationListener(showAnimListener);

    Animation cancelAnim; // init animation
    Animation.AnimationListener cancelAnimListener; //init anim listener
    toast.setCancelAnimation(showAnim);
    toast.setCancelAnimationListener(showAnimListener);

    toast.show(); //show toast view
    toast.isShowing(); // check if toast is showing now
    toast.cancel(); //cancel toast view

    toast.getView(); //get toast view to update it or to do something ..
}

Answer 4

传递给toast的自定义视图可以包含任何内容;但是，toast不能接收任何触摸事件，因此没有使用触摸事件的组件将在库存吐司（按钮，单选按钮等）中工作。您唯一的选择是创建一个自定义视图，其中包含一个按钮并将其添加到您的布局中。有许多如何执行此操作的示例以及一些可以查看其他人如何执行此操作的库。

UndoBar
MessageBar
Nurik's UndoBar

当然，也欢迎您使用我放在一起的SuperToasts库，但是对于一次使用可能有点过分。我在SuperActivityToast课程中概述了我这样做的方式。

Answer 5

您应该使用Snackbar。它是最新的android支持库（在回答时）并且与旧的api级别兼容。它比Dialog或自定义View更容易实现，并且能够使用与Toast不同的按钮。

从Android Support Library中的Extras下载SDK Manager（修订版22.2.1或更高版本）。
在build.gradle中将此添加到类依赖项：com.android.support:design:22.2.0。
实施：

Snackbar.make(this.findViewById(android.R.id.content), "Toast Message", Snackbar.LENGTH_LONG) .setAction("Click here to activate action", onClickListener) .setActionTextColor(Color.RED) .show;

就是这样。没有github项目和实现与Toast非常相似。我在我的一个项目中使用它并且效果很好。

Answer 6

在这种情况下，您可以尝试SuperToast。它可以用按钮创建烤面包。它具有自定义持续时间功能，彩色背景，彩色字体，自定义字体，动画效果。希望你会喜欢它

Answer 7

如果要添加按钮，请使用警告框:-)。这里有些例子 Dialog boxes in Android

Answer 8

Creating a system overlay window (always on top)

这表明它可以完成，我还需要吐司中的按钮，所以我仍然需要自己实现。如果我发现更多，我会将其添加到我的帖子
