[英]Change actionbar button background color when pressed
If I press a button in the action bar, then its background color is not what I want.如果我按下操作栏中的按钮,那么它的背景颜色不是我想要的。 The background color of my item doesn't respond to my click event.
我的项目的背景颜色不响应我的点击事件。 How can I change this and change the background color when it's pressed?
我如何更改它并在按下时更改背景颜色?
You need to declare android:actionBarItemBackground
attribute which is a:您需要声明
android:actionBarItemBackground
属性,它是一个:
Custom item state list drawable background for action bar items.
操作栏项目的自定义项目状态列表可绘制背景。
Then, in your styles do as follows:然后,在您的样式中执行以下操作:
<style name="CustomStyle" parent="@style/Theme.Holo.Light" >
<item name="android:actionBarItemBackground">@drawable/ab_item_background</item>
<item name="actionBarItemBackground">@drawable/ab_item_background</item>
</style>
So, put your own drawable with a selector
and every state (pressed, focused, disabled, etc) to have the expected background.因此,将您自己的 drawable 与
selector
和每个状态(按下、聚焦、禁用等)放在一起,以获得预期的背景。 For example, the drawable ab_item_background.xml
declared above might be like this:例如,上面声明的可绘制
ab_item_background.xml
可能是这样的:
<selector xmlns:android="http://schemas.android.com/apk/res/android"
android:exitFadeDuration="@android:integer/config_mediumAnimTime">
<!-- focused/pressed: color=red -->
<item
android:state_focused="true"
android:state_pressed="true"
android:drawable="@color/red" />
<!-- pressed: color=red -->
<item
android:state_pressed="true"
android:drawable="@color/red" />
<!-- normal: color=transparent -->
<item
android:drawable="@android:color/transparent" />
</selector>
In Styling the Action Bar , you can find all the customization possibles and all the attributes to do so.在设置操作栏样式 中,您可以找到所有可能的自定义和所有属性。
ActionBar actionBar = getActionBar();
actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#0a0a0a")));
