Android 无边框对话框

Android Borderless Dialog(Android 无边框对话框)

问题描述

我使用 AlertDialog.Builder 创建了一个 AlertDialog，但对话框边框在屏幕上占用了太多空间.如何删除边框?我曾尝试使用另一个 Activity 来模拟具有透明背景的对话框，但该对话框被重复使用，并且每次创建一个新 Activity 都会引入大量延迟.

I have created an AlertDialog using AlertDialog.Builder, but the Dialog border takes up too much space on the screen. How do I remove the border? I have tried using another Activity to emulate the dialog with a transparent background, but the dialog is used repeatedly, and creating a new Activity every time introduces a significant amount of lag.

这里的答案提到它可以在 ApiDemos 中找到，但我似乎找不到.

The answer from here mentions that it can be found in the ApiDemos, but i can't seem to find it.

推荐答案

好吧，我会回答我自己的问题.基本上，不是使用 AlertDialog.Builder，而是使用它的构造函数创建一个常规 Dialog，并使用合适的主题而不是默认的 Dialog 主题.

Alright, I'll answer my own question. Basically, instead of using AlertDialog.Builder, create a regular Dialog using it's constructor, and use a suitable theme instead of the default Dialog theme.

所以你的代码看起来像这样:

So your code would look something like this:

Dialog dialog = new Dialog(this, android.R.style.Theme_Translucent_NoTitleBar);

希望这对其他人有所帮助.
