Android,删除自定义按钮边框

Question

我将这个选择器代码用于我的自定义按钮(simple.xml)

  <?xml version="1.0" encoding="utf-8"?>

  <selector xmlns:android="http://schemas.android.com/apk/res/android">
      <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/focused" />
      <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/focusedpressed" />
      <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/pressed" />
      <item android:drawable="@drawable/defaultbutton" />
  </selector>

但在我的ImageButton上,我不知道如何删除边框.我想只显示我的图像,不显示按钮周围的边框.

谢谢

我替换

    <ImageButton android:id="@+id/imagebutton"
  android:src="@drawable/simple"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  />

用:

    <ImageButton android:id="@+id/imagebutton"
  android:background="@drawable/simple"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  />

和工作
