将一个活动覆盖在另一个活动上或将一个视图覆盖在另一个活动上 [英] Overlay an activity on another activity OR overlay a view over another

问题描述

我有 2 个类，FirstActivity 和 SecondActivity.

I have 2 classes, FirstActivity and SecondActivity.

第一个活动

Intent intent=new Intent(getApplicationContext(),SecondActivity.class);
startActivity(intent);

SecondActivity 是否可以叠加在 FirstActivity 上?IE.FirstActivity 变暗，SecondActivity 显示在 FirstActivity 之上.

Is it possible for SecondActivity to overlay on FirstActivity? ie. FirstActivity gets dimmed, SecondActivity gets displayed on top of FirstActivity.

如果不能用于 2 个不同的活动，是否可以在同一活动中为 2 个视图进行叠加?我希望使用对话框不是唯一的选择.

If it is not possible for 2 different activities, is it possible to do an overlay for 2 views in the same activity? I hope using dialog is not the only option.

推荐答案

我建议您将第二个 Activity 设置为对话框——这会使背景变暗.这是一个可能有用的教程:

I suggest you set your second activity up as a dialog -- which will dim the background. Here is a tutorial that could be helpful:

或者您可以简单地将清单中的主题设置为您的 SecondActivity 的对话框.

Or you can simply set the theme in the manifest as a dialog for your SecondActivity.
