xml文件如下

<?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="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/a1" />

    <EditText
        android:id="@+id/input"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:digits="1234567890"
        android:inputType="text"
        android:numeric="integer"
        android:phoneNumber="true" />

    <Button
        android:id="@+id/call"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"

    <EditText
        android:id="@+id/message"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"

    <Button
        android:id="@+id/sendmsg"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/msg" />

</LinearLayout>

别忘了添加权限呀，

manifest文件中的内容如下

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="mars.com"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8" />

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

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".TelephoneCallActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
