自定义状态栏通知

状态栏通知布局

custom_notification.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="64dp" 
    android:background="@color/white" >
    <ImageView
        android:id="@+id/image"
        android:layout_width="40dip"
        android:layout_height="40dip"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:contentDescription="@string/Image" />
    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_toRightOf="@id/image" >
        <TextView
            android:id="@+id/title"
            style="@style/NotificationTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true" />
        <TextView
            android:id="@+id/text"
            style="@style/NotificationText"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@id/title"
            android:ellipsize="end"
            android:lines="2" />
        <TextView
            android:id="@+id/time"
            style="@style/NotificationText"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBottom="@id/title"
            android:layout_alignParentRight="true"
            android:layout_marginRight="5dip"
            android:layout_toLeftOf="@id/title" />
    </RelativeLayout>
</RelativeLayout>

这里面的style都是使用的继承系统的文字样式

<!-- 自定义状态栏通知 -->
<style name="NotificationText" parent="android:TextAppearance.StatusBar.EventContent">
    <item name="android:textColor">#bb000000</item>
    <item name="android:textSize">@dimen/notification_text_size</item>
</style>
<style name="NotificationTitle" parent="android:TextAppearance.StatusBar.EventContent.Title">
    <item name="android:textColor">#bb000000</item>
</style>

创建一个通知

    /**
     * @param ctxt 上下文
     * @param tickerText    通知在状态栏的提示文本
     * @param drawable 通知在状态栏显示的图标
     * @param title 通知标题
     * @param content 通知内容
     * @param id id
     * @param pendingIntent 点击该通知要进行的操作，例如：打开一个Activity
