安卓的ImageButton有残疾的用户界面的感觉 [英] Android ImageButton with disabled UI feel

问题描述

我有一个ImageButton的是禁用（不点击，或者设置为禁用）。我想举一个UI觉得它是禁用的，而无需使用任何其它图像的用户。

I have an ImageButton which is disabled (non clickable or set as disabled). I want to give an UI feel to the user that it is disabled without using any other image.

有没有办法做到这一点？

Is there any way to do this?

推荐答案

不同于普通的按钮，一个的ImageButton 或按钮，有一个形象的背景不呈灰色禁用时。实际上，你必须使用另一幅图像或处理它在某种程度上，它显示为灰色。

Unlike a regular Button, an ImageButton or a Button that has an image background is not grayed when disabled. You actually have to use another image or to process it in a way it appears grayed.

如果使用另一种形象是好的，您可以使用＆LT做到这一点C $ C>但这amongs同一个）：

Should using another image be ok, you can do this by using a <selector> (here associated to a regular Button but this amongs to the same):

• /drawable/my_selector.xml ：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_enabled="false"
        android:drawable="@drawable/button_gray" /> ***button_gray is a Drawable image***
    <item android:state_pressed="true"
        android:drawable="@drawable/button_gray" /> 
    <item android:drawable="@drawable/button_red" /> ***button_red is a Drawable image*** 
</selector>

下面，button_red用所有的时间，但是当按钮被禁用或推。

Here, button_red is used all the time but when the button is disabled or being pushed.

• 您 layout.xml ：

<Button android:id="@+id/myButton"
        android:background="@drawable/my_selector" ***this is a reference to the selector above ***
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
/>

和应该使用其他的图像是一个问题，其他的答案，如@ Tronman的或@ southerton我们给你的方法来处理它在某种程度上，它显示为灰色。

And should using another image be a problem, other answers such as @Tronman's or @southerton's give you ways to process it in a way it appears grayed.
