android实现打电话和发送短信功能例子，复制代码即可使用。
解决方法：
1、activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_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"
android:id="@+id/root"
tools:context="com.example.ff.MainActivity" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="打电话和发短信" />
<EditText
android:id="@+id/editNum"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/textView1"
android:layout_below="@+id/textView1"
android:layout_marginTop="15dp"
android:hint="输入电话号码"
android:ems="10"
android:inputType="phone" >
<requestFocus />
</EditText>
<EditText
android:id="@+id/editSms"
android:layout_marginTop="10dp"
android:minLines="3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/editNum"
android:layout_below="@+id/editNum"
android:hint="请输入短信内容"
android:ems="10" />
<Button
android:id="@+id/btnCall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/editSms"
android:layout_below="@+id/editSms"
android:layout_marginLeft="21dp"
android:layout_marginTop="10dp"
android:text="拨打电话" />
<Button
android:id="@+id/btnSms"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignRight="@+id/editSms"
android:layout_alignTop="@+id/btnCall"
android:layout_marginRight="50dp"
android:text="发短信" />
</RelativeLayout>

String phone =editNum.getText().toString();
//判断电话是否为空
if("".equals(phone)){
Toast.makeText(MainActivity.this, "电话号码不能为空", Toast.LENGTH_SHORT)
.show();
return;
}
//使用Intent调用打电话的功能
Intent intent = new Intent();

}
};
@Override

Intent intent = new Intent();
intent.setAction(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:"+editNum.getText().toString()));
startActivity(intent);
}else if(title.equals("回到Home")){
Intent intent = new Intent();
intent.setAction(Intent.ACTION_MAIN);
//添加category属性
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);
}
return true;
}
}
3、AndroidManifest.xml修改
在uses-sdk标签后面添加（设置打电话权限）：<uses-permission android:name="android.permission.CALL_PHONE"/>
