Set a minimum width at the top most layout.

For example:

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"

I just want to fill only 80% of the screen for that I did like this below

<pre><code> DisplayMetrics metrics = getResources().getDisplayMetrics();
 int screenWidth = (int) (metrics.widthPixels * 0.80);

 setContentView(R.layout.mylayout);

 getWindow().setLayout(screenWidth, LayoutParams.WRAP_CONTENT); //set below the setContentview
</code></pre>

it works only when I put the getwindow().setLayout... line below the setContentView(..)

thanks @Matthias

You may add this values to your style android:windowMinWidthMajor and android:windowMinWidthMinor

<pre><code>&lt;style name="Theme_Dialog" parent="android:Theme.Holo.Dialog"&gt;
 ...
 &lt;item name="android:windowMinWidthMajor"&gt;97%&lt;/item&gt;

blocks|key|1248457|text|Matthias的答案大部分是正确的，但它仍然没有填满整个屏幕，因为它的两边都有一个小填充(@Holmes指出)。除了他的代码之外，我们可以通过扩展Theme.Dialog样式来修复这个问题，并添加一些如下所示的属性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1248458|<style+name="MyDialog"+parent="@android:style/Theme.Dialog">
++++<item+name="android:windowBackground">@android:color/transparent</item>

Matthias' answer is mostly right but it's still not filling the entire screen as it has a small padding on each side (pointed out by @Holmes). In addition to his code, we could fix this by extending Theme.Dialog style and add some attributes like this.

<pre><code>&lt;style name="MyDialog" parent="@android:style/Theme.Dialog"&gt;
 &lt;item name="android:windowBackground"&gt;@android:color/transparent&lt;/item&gt;
 &lt;item name="android:windowNoTitle"&gt;true&lt;/item&gt;
&lt;/style&gt;
</code></pre>

Then we simply declare Activity with theme set to <code>MyDialog</code>:

<pre><code>&lt;activity
 android:name=".FooActivity"
 android:theme="@style/MyDialog" /&gt;
</code></pre>

This would be helpful for someone like me. Create custom dialog style:

<pre><code>&lt;style name="MyDialog" parent="Theme.AppCompat.Light.Dialog"&gt;
 &lt;item name="windowNoTitle"&gt;true&lt;/item&gt;
 &lt;item name="android:windowFullscreen"&gt;true&lt;/item&gt;
 &lt;item name="android:windowIsFloating"&gt;false&lt;/item&gt;
&lt;/style&gt;
</code></pre>

In <code>AndroidManifest.xml</code> file set theme for wanted activity:

<pre><code>&lt;activity
 android:name=".CustomDialog"
 ...
 android:theme="@style/MyDialog"/&gt;
</code></pre>

That is all, no need to call methods programaticaly.

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.

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.

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?

How can I get a Dialog style activity window to fill the screen?

容器

我正在使用具有对话主题集的活动，并且我希望它是全屏的。我尝试了各种方法，甚至通过WindowManager手动将窗口扩展到全宽和全高，但都不起作用。显然，对话框窗口(或具有对话框主题的活动)只会根据其内容展开，但即使这样也不总是有效。例如，我显示了一个进度条圆，它的宽度和高度都设置为FILL_PARENT (布局容器也...
