具体操作：自定义消息通知内容布局；点击界面中心的“点击发送消息”TextView控件，模拟发送通知消息，通知栏接收消息，点击几次则发送几次，点击通知栏消息，跳转到详情界面。
1.activity_main.xml：

2.layout_item.xml：
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:src="@mipmap/ic_launcher" /> <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="18dp" android:layout_toRightOf="@+id/imageView1" android:text="TextView" /> <TextView android:id="@+id/textView2" 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:text="TextView" /> <TextView android:id="@+id/textView3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/textView1" android:layout_marginLeft="54dp" android:layout_toRightOf="@+id/textView2" android:text="TextView" /> <TextView android:id="@+id/textView4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_below="@+id/textView1" android:text="TextView" /></RelativeLayout>
3.activity_detail.xml：
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="New Text" android:id="@+id/name" android:textSize="18sp" android:layout_gravity="center_horizontal"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="New Text" android:id="@+id/price" android:textSize="18sp" android:layout_gravity="center_horizontal"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="New Text" android:id="@+id/detail" android:textSize="18sp" android:layout_gravity="center_horizontal"/></LinearLayout>
