Android中Intent的用法小结

Android中Intent的用法总结
     刚入手Android,昨天在看android书籍的时候,看到Intent有个Intent.putExtras(Bundle b)的方法,然后在Eclipse中智能输入时有Intent.putExtra(X,Y)相关的很多方法putExtras不知道是不是putExtra的复数形式?
      Intent只在Android中特有,我把它比作一种运载工具,就像飞机一样,会把一些人带到某个地方,而且如果需要的话,还可以找到机上有哪些人员(数据),这就需要另外一些设备来支持(如:Bundle),最后通过引擎(Context的 Activity)来启动。


      以下是从网上摘来的:前人已有整理,就方便了我们这些后辈了。
1.显示网页:
Uri uri = Uri.parse("http://www.google.com");
Intent it  = new Intent(Intent.ACTION_VIEW,uri);
startActivity(it);


2.显示地图:
Uri uri = Uri.parse("geo:38.899533,-77.036476"); 
Intent it = new Intent(Intent.Action_VIEW,uri); 
startActivity(it); 


3.从google搜索内容
Intent intent = new Intent();
intent.setAction(Intent.ACTION_WEB_SEARCH);
intent.putExtra(SearchManager.QUERY,"searchString")
startActivity(intent);


4.路径规划
Uri uri = Uri.parse("http://maps.google.com/maps?f=dsaddr=startLat%20startLng&daddr=endLat%20endLng&hl=en"); 
Intent it = new Intent(Intent.ACTION_VIEW,URI); 
startActivity(it); 


5.拨打电话
Uri uri = Uri.parse("tel:xxxxxx");
Intent it = new Intent(Intent.ACTION_DIAL, uri);  
startActivity(it); 
[color=blue]//要使用这个必须在配置文件 中加入<uses-permission id="android .permission.CALL_PHONE" />[/color] 


6.调用发短信的程序

Intent it=new Intent(Intent.ACTION_SEND);
