<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" android:background="@drawable/jibin"> 

    <EditText 
     android:id="@+id/msg" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" android:hint="Enter the message"> 

     <requestFocus /> 
    </EditText> 

    <EditText 
     android:id="@+id/num" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:inputType="text|textPersonName" android:hint="Enter a number"/> 

    <Button 
     android:id="@+id/send" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:text="Send" />

請發佈運行時exception from logcat。很難說沒有這一點，但我的猜測是，你有沒有要求相應的權限，你可以添加以下到您的清單XML文件的頂級manifest節點：

<uses-permission android:name="android.permission.SEND_SMS" />
