他们是如何做到的呢?主屏幕上的对话框 [英] How do they do it? Dialogs over home screen

问题描述

我正在编写一个 Android 应用程序，我想在主屏幕上放置一个对话框或视图，以便用户无需跳转到我的完整应用程序即可输入文本.我似乎无法让它工作.如果我呈现一个对话框(即使是在一个透明的活动中)，我的应用程序也会启动.

I'm writing an Android application and I would like to place a dialog or view over the home screen so that a user can enter text without jumping into my full application. I can't seem to get this to work. If I present a dialog (even in a transparent activity), my application launches.

如果您不知道我在说什么，请查看 Facebook 小部件.我想复制与单击你在想什么?"类似的行为.盒子.

If you don't know what I'm talking about, take a look at the Facebook widget. I want to replicate a similar behavior to the clicking on the "What's on your mind?" box.

提前感谢您的帮助！

推荐答案

我的问题是应用程序总是启动以显示对话框.

My problem was that the application always launched to display the dialog.

为了解决这个问题，我在清单中将活动启动模式设置为 singleInstance.现在它会在主屏幕上显示对话框！

To solve this, I set the activity lauch mode to singleInstance in the manifest. Now it shows the dialog over the home screen!
