Android系统自带的intent

使用intent调用Android系统自带应用 

 

显示网页:

Uri uri = Uri.parse("http://www.google.com");

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); 

路径规划:

Uri uri = Uri.parse("http://maps.google.com/maps?f=d&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：<只显示拨号程序>

Uri uri = Uri.parse("tel:123456789");

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

startActivity(it);  

拨打电话：<已经拨打出去>

Uri uri = Uri.parse("tel.123456789");

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

startActivity(it);  

要使用这个必须在配置文件中加可以打电话的权限:

<uses-permission id="android.permission.CALL_PHONE" />
