Intent的常见用法

Intent应该算是Android中特有的东西。你可以在Intent中指定程序要执行的动作（比如：view,edit,dial），以及程序执行到 该动作时所需要的资料。都指定好后，只要调用startActivity()，Android系统会自动寻找最符合你指定要求的应用程序，并执行该程序。

下面列出几种Intent的用法
显示网页:

Uri uri = Uri.parse(
"<a href="
http:
//www.google.com" target="_blank" rel="external">http://www.google.com</a>");
Intent it  = new
 Intent(Intent.ACTION_VIEW,uri);
startActivity(it);

Uri uri = Uri.parse("<a href="http://www.google.com" target="_blank" rel="external">http://www.google.com</a>");
Intent it  = new Intent(Intent.ACTION_VIEW,uri);
startActivity(it);

显示地图:

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

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

路径规划:

Uri uri = Uri.parse(
"<a href="
http:
//maps.google.com/maps?f=d" target="_blank" rel="external">http://maps.google.com/maps?f=d</a>&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");

Intent it = new
 Intent(Intent.ACTION_VIEW,URI);

startActivity(it);

Uri
uri = Uri.parse("<a href="http://maps.google.com/maps?f=d"
target="_blank"
rel="external">http://maps.google.com/maps?f=d</a>&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");
Intent
it = new Intent(Intent.ACTION_VIEW,URI);
startActivity(it);

拨打电话:
调用拨号程序

Uri uri = Uri.parse(
"tel:xxxxxx"
);

Intent it = new
 Intent(Intent.ACTION_DIAL, uri);

startActivity(it);

Uri uri = Uri.parse("tel:xxxxxx");
Intent it = new Intent(Intent.ACTION_DIAL, uri);  
startActivity(it); 

Uri uri = Uri.parse(
"tel.xxxxxx"
);

Intent it =new
 Intent(Intent.ACTION_CALL,uri);

要使用这个必须在配置文件中加入<uses-permission id="android.permission.CALL_PHONE"
 />

Uri uri = Uri.parse("tel.xxxxxx");
Intent it =new Intent(Intent.ACTION_CALL,uri);
要使用这个必须在配置文件中加入<uses-permission id="android.permission.CALL_PHONE" />
