Appcompat警报对话框“操作"按钮背景处于按下状态 [英] Appcompat Alert Dialog Action button background On pressed state

问题描述

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.
