activity_main.xml

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3     android:id="@+id/activity_main"
 4     android:layout_width="match_parent"
 5     android:layout_height="match_parent"
 6     android:orientation="vertical">
 7     <EditText
 8         android:id="@+id/phone"
 9         android:layout_width="match_parent"
10         android:layout_height="25dp"
11         android:hint="请输入手机号" />
12     <Button
13         android:id="@+id/cal"
14         android:layout_width="match_parent"
15         android:layout_height="wrap_content"
16         android:onClick="onClick"
17         android:text="拨号"/>
18 </LinearLayout>
