我怎样才能得到一个对话式的活动窗口以填充屏幕？ [英] How can I get a Dialog style activity window to fill the screen?

问题描述

我使用与对话的主题集中的活动，我希望它是全屏显示。我试过各种各样的事情，即使是经过窗口管理器，手动扩大窗口至全屏宽度和高度，但没有任何工程。

I am using an activity with the dialog theme set, and I want it to be full screen. I tried all sorts of things, even going through the WindowManager to expand the window to full width and height manually, but nothing works.

显然，一个对话框窗口（或对话框主题活动）将只根据其内容扩大，但即使这并不总是奏效。举例来说，我显示一个进度条圆其具有高度和宽度设置为FILL_PARENT（这样做它的布局容器），但尽管如此，各地要小得多进度条，而不是填充屏幕的对话框包裹。

Apparently, a dialog window (or an activity with the dialog theme) will only expand according to its contents, but even that doesn't always work. For instance, I show a progress bar circle which has width and height set to FILL_PARENT (so does its layout container), but still, the dialog wraps around the much smaller progress bar instead of filling the screen.

必须有显示小东西里面的对话窗口的方式，但把它扩展到全屏幕大小没有它的内容调整呢？

There must be a way of displaying something small inside a dialog window but have it expand to full screen size without its content resizing as well?

推荐答案

我找到了解决办法：

在你的活动已在 Theme.Dialog 风格设置，做到这一点：

In your activity which has the Theme.Dialog style set, do this:

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

    setContentView(R.layout.your_layout);

    getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
}

这一点很重要，你叫 Window.setLayout（）的在的你叫的setContentView（），否则将无法正常工作。

It's important that you call Window.setLayout() after you call setContentView(), otherwise it won't work.
