安卓中的几种形式的通知

主布局文件：

<span style="font-size:18px;"><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="普通通知"        android:onClick="click1" />    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="大视图通知"        android:onClick="click2" />    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="带进度条通知"        android:onClick="click3" />    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="自定义通知"        android:onClick="click4" /></LinearLayout></span>

前两种通知跳转的第二个布局页面

<span style="font-size:18px;"><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    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=".Second" >    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/hello_world" /></RelativeLayout></span>

自定义通知用到的布局文件：

<span style="font-size:18px;"><?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"    android:orientation="vertical" >    <TextView         android:id="@+id/tv1"                android:layout_width="wrap_content"        android:layout_height="wrap_content"/>       <ImageView         android:id="@+id/iv"        android:layout_below="@id/tv1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"/>     <TextView         android:id="@+id/tv2"        android:layout_toRightOf="@id/iv"        android:layout_width="wrap_content"        android:layout_height="wrap_content"/>    </RelativeLayout></span>

主逻辑代码：
