android Uri的常用几个例子

一下是从网上借来的

 

显示网页:
  1. Uri uri = Uri.parse("http://www.google.com");
  2. Intent it = new Intent(Intent.ACTION_VIEW,uri);
  3. startActivity(it);

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

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

拨打电话:
调用拨号程序
  1. Uri uri = Uri.parse("tel:xxxxxx");
  2. Intent it = new Intent(Intent.ACTION_DIAL, uri);  
  3. startActivity(it);  
  1. Uri uri = Uri.parse("tel.xxxxxx");
  2. Intent it =new Intent(Intent.ACTION_CALL,uri);
  3. 要使用这个必须在配置文件中加入<uses-permission );  
Intent it = new Intent(Intent.ACTION_VIEW, uri);  
startActivity(it);  
//where pkg_name is the full package path for an application

//进入联系人页面
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(People.CONTENT_URI);
startActivity(intent);

//查看指定联系人
Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, info.id);//info.id联系人ID
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(personUri);
startActivity(intent);
