Set background color for Dialog titlebar?
提问by user246114
I'm creating a class derived from Dialog. The titlebar of the dialog looks really nice, it's a dark grey color that is somewhat transparent. Is there a way to set the color used for the background of the titlebar? The grey is cool, but I would like to set it to some custom color. I don't think this is possible, I think I'd need to supply my own stretchable background dialog resource. Is that right?
我正在创建一个派生自 Dialog 的类。对话框的标题栏看起来非常漂亮，它是一种有点透明的深灰色。有没有办法设置用于标题栏背景的颜色？灰色很酷，但我想将其设置为某种自定义颜色。我认为这是不可能的，我想我需要提供我自己的可拉伸背景对话框资源。那正确吗？
Thanks
谢谢

Use the below code:
使用以下代码：
final Dialog mailDialog = new Dialog(MainActivity.this);
mailDialog.getWindow().setBackgroundDrawableResource(R.drawable.dialog_box);
And create a custom dialog box xml in drawable folder as below:
并在 drawable 文件夹中创建一个自定义对话框 xml，如下所示：
dialog_box.xml
dialog_box.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<corners
android:bottomLeftRadius="5dp"
android:bottomRightRadius="5dp"
android:topLeftRadius="5dp"
android:topRightRadius="5dp" />
<gradient
android:angle="-90"
android:centerColor="#660D1E4A"
android:endColor="#66011444"
android:startColor="#66505E7F"
android:type="linear"
/>
<stroke
android:dashGap="0dp"
android:dashWidth="0dp"
android:width="1dp"
android:color="#ffffffff" />
</shape>
Hope this helps you.

You can use:
您可以使用：
this.getWindow().setBackgroundDrawableResource(R.color.blue);
That will set the entire window color including the titlebar.
这将设置包括标题栏在内的整个窗口颜色。
You can then change the background color for the layout of the dialog which is everything but the titlebar to whatever you like and the title bar will remain blue.
然后，您可以将对话框布局的背景颜色更改为您喜欢的任何内容，但标题栏将保持蓝色。

The best way is to use a custom dialog where you can then customize its look.
最好的方法是使用自定义对话框，然后您可以在其中自定义其外观。
Have a look at Set AlertBox Title Bar Background Colorand this http://developer.android.com/guide/topics/ui/dialogs.htmlon how to go about it.
看看设置警报框标题栏背景颜色和这个http://developer.android.com/guide/topics/ui/dialogs.html关于如何去做。

dialog = new Dialog(this); // your dialog
dialog.getWindow().setTitleColor(R.color.blue_background);

The background color of the title section can easily be set this way:
标题部分的背景颜色可以通过这种方式轻松设置：
int titleLayoutId = dialog.getContext().getResources().
getIdentifier("topPanel", "id", "android");
LinearLayout layout = (LinearLayout) dialog.findViewById(titleLayoutId);
if (layout != null) {
layout.setBackgroundColor(yourColor);
}
This eliminates the need to create a custom layout.
这消除了创建自定义布局的需要。

dialog.getWindow().setTitleColor(getResources().getColor(R.color.blue));
