我在可绘制文件夹中有 textfield_activated_holo_light.9.png。但为什么我会收到这个错误?

从您的 xml 中删除它(在 EditText 中)

 android:onClick="@drawable/textfield_activated_holo_light"

就突出显示editext而言,您可以这样做:

1)定义一个xml文件说mybackground.xml

<?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/textfield_activated_holo_light" /> <!-- pressed -->
  <item android:state_focused="true"
   android:drawable="@drawable/textfield_activated_holo_light" /> <!-- focused -->
  <item android:drawable="@drawable/default" /> <!-- default -->
</selector>

2)将此xml复制到drawable文件夹中

3)将此xml设置为xml文件中editext的背景:

  <EditText
        android:id="@+id/k1_editText"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/k1"
        android:layout_alignLeft="@+id/al_const_editText"
        android:layout_alignTop="@+id/k1"
        android:background="@drawable/mybackground"
        android:ems="10"
        android:enabled="true"
        android:focusable="true"
        android:inputType="numberDecimal"
        android:textColor="@color/White"
        android:textSize="30sp"            
        android:visibility="visible" >

覆盖OnClickListenerinonStart()然后在你的onClick(View v), 设置v.setBackgroundResource(getResources().getDrawable(R.drawable.textfield_activated_holo_light)
