将活动显示为对话框时如何自定义宽度和高度

If I have defined a Activity:

如果我已经定义了一个Activity:

public class DialogActivity extends Activity{

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(dialog_activity.xml);
    }


}

I would like to display the above activity like a dialog, so in the AndroidManifest.xml file, I declare this activity like below:

我想像对话框一样显示上面的活动,所以在AndroidManifest.xml文件中,我声明这个活动如下:

<activity android:name=".DialogActivity" android:theme="@android:style/Theme.Dialog"/>

Everything is fine at this point, my DialogActivity showed as a dialog.

此时一切都很好,我的DialogActivity显示为一个对话框。

The problem is How to customize the width and height of the DialogActivity to make it more like a small dialog? (Currently it occupies most of the screen by default)

问题是如何自定义DialogActivity的宽度和高度,使其更像一个小对话框? (目前它默认占据大部分屏幕)

----------------------------Update-----------------------

I defined a custom theme like below:

我定义了一个自定义主题如下:

<style name="myDialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>

        <item name="android:width">100dip</item> 
        <item name="android:height">100dip</item>

</style>

Then, declare the DialogActivity in AndroidManifest.xml as.

然后,将AndroidManifest.xml中的DialogActivity声明为。

<activity android:name=".DialogActivity" android:theme="@style/myDialog"/>

My DialogActivity now even occupies the whole screen:( . The width and height definition:

我的DialogActivity现在甚至占据整个屏幕:(。宽度和高度定义:

<item name="android:width">100dip</item>

in the theme do not take any effect, why?

在主题上没有任何效果,为什么?

5 个解决方案

#1

I finally figured out one way to customize the size of my DialogActivity.

我终于想出了一种自定义DialogActivity大小的方法。

That's inside the onCreate() method of DialogActivity, add the following code:

这是在DialogActivity的onCreate()方法内,添加以下代码:

WindowManager.LayoutParams params = getWindow().getAttributes();  
params.x = -20;  
params.height = 100;  
params.width = 550;  
params.y = -10;  

this.getWindow().setAttributes(params);

I had similar problem, I used following theme for my activity

我有类似的问题,我使用以下主题进行我的活动

android:theme="@style/Base.Theme.AppCompat.Light.Dialog"

The following code fixed my problem

以下代码修复了我的问题

 setContentView(R.layout.activity_layout);
 getWindow().setLayout(width(pixels),height(pixels));

You need to supply your own dialog theme, see http://developer.android.com/guide/topics/ui/themes.html and How to change theme for AlertDialog

您需要提供自己的对话框主题,请参阅http://developer.android.com/guide/topics/ui/themes.html以及如何更改AlertDialog的主题

#4

You can set the layout height and width in layout xml file

您可以在布局xml文件中设置布局高度和宽度

You can even mention the values like "240px" for android:layout_width/android:layout_height

你甚至可以为android提供像“240px”这样的值:layout_width / android:layout_height

#5

There's a one-line code without hassling with the LayoutParams that is

有一个单行代码,没有对LayoutParams的麻烦

getWindow().setLayout((int)(width*.8),(int)(height*.25));

This is what I've used before in one of my projects and now searching for, but found it in the same project.

这是我之前在我的一个项目中使用过的,现在正在搜索,但在同一个项目中找到它。
