100%运行通过，有图有真相！！！
第一步：布局文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/phone_number" />
<EditText
android:id="@+id/phone_number"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="phone"/>
<Button
android:id="@+id/start_btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/start_call"/>
<Button
android:id="@+id/end_btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/end_call"/>
</LinearLayout>
