Android is dynamically set via parameters ImageView

I have such a scene in the course of my study. Like the weather forecast. I will parse the data according to the request, which is to change the weather icon according to the different daily or hourly

In this process, I think of the IF statement to judge, but I think this is unrealistic, too cumbersome. I found that the data I requested would probably have more than 30 icons, that is, if I use the IF statement to interpret

, I'm going to write 30 if .....

But I learned a way, I share to everyone to learn!!!!

Create Levellist.xml in the Drawable folder

Such as:

Set the src of Image view to a created XML file in Layout

Set in Java code

Imagetianqi_tv.getdrawable (). SetLevel (0);
This 0 represents the Evellist.xml.

Android:maxlevel= "0"
