关于一个程序中多个Notification的精确控制
Problem:
When a notification is selected, Tabs activity is called passing the intent. I want to access the unique notificationId of the notification that was selected in Tabs. I tried intent.putExtra() to save the notificationId in the intent. But, for multiple notifications its overwriting the notificationId and returns the latest one. I dont understand as to why this is happening and how can i avoid this overwriting of notificationId.

Answer:
I got the answer. The intents were getting cached in. To, make a new intent, just add the following piece of code:

intent.setData((Uri.parse("custom://"+System.currentTimeMillis())));

This makes the intent unique.

Also, someone suggested me the following piece of code to make the intent unique:

intent.setAction("actionstring" + System.currentTimeMillis());

It didnt help me, but might be of help to someone else.

如果想设置图片固定大小，又想保持图片宽高比，需要如下设置：

1 ） 设置 setAdjustViewBounds 为 true ；

2 ） 设置 maxWidth 、 MaxHeight ；

3 ） 设置设置 layout_width 和 layout_height 为 wrap_content 。

 

	<LinearLayout 
	    android:orientation="horizontal"
	    android:layout_width="fill_parent"
	    android:layout_height="wrap_content"
	    android:layout_marginTop="10px"
    	>
    	<ImageView
	    	android:adjustViewBounds="true"
    		android:layout_width="fill_parent"
	    	android:layout_height="160px"
	    	android:scaleType="fitCenter"
		    android:layout_gravity="center"
	    	android:src="/blog_article/@drawable/icon/index.html"
    		/>
    </LinearLayout>

横竖屏设置，在AndroidManifest.xml里面配置一下
android:screenOrientation="landscape"
（landscape是横向，portrait是纵向）
