Thread与Handler

好吧，废话就少说了。开始觉着这个线程真的就不费事，后来，到现在。。。嘿嘿，要是牵涉到一些活跃的赋值以及得到东西，为了线程的安全，好像我们都离不开它哦！

今天，不是要做一个可以从网上动态获取数据的应用嘛，所以，这里在获取网络图片的时候，我遇到一个问题：

first：网络图片都是URl的，而我等待赋值的这些控件除了ImageView还有Button以及布局。。。。imageview以及button还好说咯可是布局呢？

也就是说这里必须要将Url转换成Drawable类型的。

而且是获得多张，于是，我是这样打算的：

先定义一个数组，然后将这些url全部写出来，然后将他转换成drawable类型的，然后再利用handler去更新界面。。。。不错不错。。。

其实网上有很多这样关于这两者的代码，可是就是木有获取一连串的字符（url）然后来进行转换的。所以，就记下来了，方便自己，也方便大家嘛。。。

这里面的代码 我是完全没做修改了！嘿嘿，看懂了就懂了，其实我这个循环可能会很累赘，大家有什么好的，提提咯！期待。。。
