如何为不同状态设置图像按钮背景图像? [英] How to set image button backgroundimage for different state?

问题描述

我想要两种状态的图像按钮 i) 正常 ii) 触摸(或点击).

I want imagebutton with two states i) normal ii) touch(or click).

我在 imagebutton 背景中设置了 normal 图像，我正在尝试更改 图像(按下)来自 onclick 方法，但它不会改变.

I have set normal image in the imagebutton background and I am trying to change image(pressed) from onclick method, but it doesn't change.

我希望如果我按下图像按钮，那么图像应该从正常变为按下，直到我按下其他按钮但它不会发生.

任何人都可以向我建议如何使用选择器或在运行时做到这一点?

Can anyone suggest to me how can I do this with selector or at run time?

这是我的图像按钮面板代码.

Here is my imagebuttonpanel code.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="horizontal"
  android:gravity="bottom"
  android:id="@+id/buttonpanel">
  <ImageButton android:id="@+id/buttonhome"
               android:layout_width="80dp"
               android:layout_height="36dp"
               android:focusable="true" 
               android:background="@drawable/homeselector">
               </ImageButton>
  <ImageButton android:id="@+id/buttonsearch"
               android:layout_height="36dp"
               android:layout_width="80dp"
               android:background="@drawable/searchselector"
               android:focusable="true">
               </ImageButton>>
  <ImageButton android:id="@+id/buttonreg"
               android:layout_height="36dp"
               android:layout_width="80dp"
               android:background="@drawable/registerselector"
               android:focusable="true">
               </ImageButton>>
  <ImageButton android:id="@+id/buttonlogin"
               android:layout_height="36dp"
               android:layout_width="80dp"
               android:background="@drawable/loginselector"
               android:focusable="true">
               </ImageButton>
</LinearLayout>

而我的选择器 xml 是

and my selector xml is

<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!--<item android:state_pressed="true" android:drawable="@drawable/homehover" 
        /> <item android:state_focused="true" android:drawable="@drawable/homehover" 
        /> <item android:drawable="@drawable/home" /> <item android:state_window_focused="true" 
        android:drawable="@drawable/homehover" /> -->
    <item android:state_enabled="false" android:drawable="@drawable/homehover" />
    <item android:state_pressed="true" android:state_enabled="true"
        android:drawable="@drawable/homehover" />
    <item android:state_focused="true" android:state_enabled="true"
        android:drawable="@drawable/homehover" />
    <item android:state_enabled="true" android:drawable="@drawable/home" />

</selector> 

而且我还尝试在 ontouch 和 onclick 事件上更改图像资源，但没有帮助.

And I have also tried to change image resource on ontouch and onclick event, but it does not help.

推荐答案

像这样在你的 drawable 中创建一个 xml 文件:

Create an xml file in your drawable like this :

<?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/btn_sendemail_disable" />
    <item
        android:state_pressed="true"
        android:state_enabled="true"
        android:drawable="@drawable/btn_send_email_click" />
    <item
        android:state_focused="true"
        android:state_enabled="true"
        android:drawable="@drawable/btn_sendemail_roll" />
    <item
        android:state_enabled="true"
        android:drawable="@drawable/btn_sendemail" />
</selector>

并相应地设置图像，然后将此 xml 设置为 imageButton 的背景.

And set images accordingly and then set this xml as background of your imageButton.
