## 读取短信内容 ##

读取短信的内容就要知道短信放在哪里，然后通过查询语句把结果封装到实体类的List中，再全部打印出来即可。  
下面是具体的代码：  
activity\_main.xml

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/bg" android:orientation="vertical" tools:context=".MainActivity">
    
        <TextView android:id="@+id/tv_des" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="18dp" android:paddingLeft="20dp" android:text="读取到的系统短信如下：" android:textSize="20sp" android:visibility="invisible">
    
        </TextView>
    
        <TextView android:id="@+id/tv_sms" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@id/tv_des" android:layout_marginTop="0dp" android:lines="20" android:paddingLeft="20dp" android:paddingTop="10dp" android:textSize="16sp">
    
        </TextView>
    
        <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" android:layout_marginBottom="28dp" android:layout_marginLeft="26dp" android:layout_marginStart="26dp" android:background="#149EDD" android:onClick="readSms" android:padding="5dp" android:text="查看短信" android:textSize="30sp">
    
        </Button>
    
    </RelativeLayout>
