我正在尝试从appcompat v7 22.1.1中新建AlertDialog.
I am trying new AlertDialog from appcompat v7 22.1.1.
它在图像中的效果很好(在所有android版本中).
It works pretty well (In all android versions) as in image.
AlertDialog的样式是这个. (目前,我使用的是硬编码的颜色值,而不是颜色资源)
Style for AlertDialog is this. (For now I am using hardcoded color values instead of color resources)
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> <item name="colorPrimaryDark">#111111</item> <item name="colorPrimary">#00ddff</item> <item name="colorAccent">#0044aa</item> <item name="colorButtonNormal">#00aaaa</item> <item name="colorControlHighlight">#00ddff</item> <item name="alertDialogTheme">@style/AlertDialogTheme</item> </style> <style name="AlertDialogTheme" parent="Theme.AppCompat.Dialog.Alert"> <item name="colorAccent">#0044aa</item> <item name="android:background">#ffffff</item> <item name="android:textColorPrimary">#000000</item> <item name="android:windowTitleStyle">@style/MyTitleTextStyle</item> </style> <style name="MyTitleTextStyle"> <item name="android:textColor">#0044aa</item> <item name="android:textAppearance">@style/TextAppearance.AppCompat.Title</item> </style>我的问题是,
1)如何更改状态在图像中四舍五入为圆形(灰色)的已按下颜色?
2)android> = 21中没有按下的颜色,这有什么用呢?
2) No pressed color is there in android >= 21 , what is hack for this ?
3)如何为操作按钮设置不同颜色(可以)?
3) How can I have different colors of action buttons (Is it possible)?
任何帮助都会很棒.
推荐答案您可以使用样式属性,例如
You can use style attributes like
- buttonBarButtonStyle
- buttonBarNegativeButtonStyle
- buttonBarNeutralButtonStyle
- buttonBarPositiveButtonStyle
- buttonBarButtonStyle
- buttonBarNegativeButtonStyle
- buttonBarNeutralButtonStyle
- buttonBarPositiveButtonStyle
示例:
<style name="dialog_theme" parent="Theme.AppCompat.Dialog.Alert"> <item name="buttonBarNegativeButtonStyle">@style/dialog_button.negative</item> <item name="buttonBarPositiveButtonStyle">@style/dialog_button.positive</item> </style> <style name="dialog_button"> <item name="android:textStyle">bold</item> <item name="android:minWidth">64dp</item> <item name="android:paddingLeft">8dp</item> <item name="android:paddingRight">8dp</item> <item name="android:background">@drawable/dialogButtonSelector</item> </style> <style name="dialog_button.negative"> <item name="android:textColor">#f00</item> </style> <style name="dialog_button.positive"> <item name="android:layout_marginLeft">8dp</item> <item name="android:textColor">#00f</item> </style>dialogButtonSelector是我们自定义的可绘制选择器.
Where dialogButtonSelector is our custom drawable selector.
不幸的是,在dialog_button上设置背景会破坏我们的填充和边距,因此我需要再次设置它.
Unfortunatelly setting background on dialog_button destroy our paddings and margins so I need to set it again.
dialog_button样式可以通过Widget.AppCompat.Button.ButtonBar.AlertDialog继承,但是我发现它缺少textStyle bold之类的样式.
dialog_button style can inherit through Widget.AppCompat.Button.ButtonBar.AlertDialog but I found that it has missing styles like textStyle bold.
