intent.setAction的介绍

在android开发的过程中，可能会调用android操作系统一些自带的功能，比如调用一个拨号器等等。

在调用android系统自带功能时，我们要告诉android，我们要调用哪个功能，如何告诉呢，通过intent（意图）对象。

eg:                

Intent it=new Intent();

                it.setAction("android.intent.action.CALL");

                it.setData(Uri.parse("tel:"+s_num));

                startActivity(it);

下面把android中，常用的功能列出来。

Intent intent = new Intent(); 
intent.setAction(Intent.ACTION_WEB_SEARCH); 
intent.putExtra(SearchManager.QUERY,"searchString") 
startActivity(intent);
