下面是我的imagebuttonpanel code。

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>

和我的选择XML是

<?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> 

和我也试图改变图像资源的ontouch和onclick事件，但它并不能帮助。

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

推荐答案

建立在你绘制一个XML文件是这样的：

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>

和相应的设置图像，然后将该XML作为背景的​​的ImageButton 。

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