下面列出几种Intent的用法 显示网页:- Uri uri = Uri.parse("");
- Intent it = new Intent(Intent.ACTION_VIEW,uri);
- startActivity(it);
复制代码 显示地图:- Uri uri = Uri.parse("geo:38.899533,-77.036476");
- Intent it = new Intent(Intent.Action_VIEW,uri);
- startActivity(it);
复制代码 路径规划:- Uri uri = Uri.parse("%20startLng&daddr=endLat%20endLng&hl=en");
- Intent it = new Intent(Intent.ACTION_VIEW,URI);
- startActivity(it);
复制代码 拨打电话: 调用拨号程序- Uri uri = Uri.parse("tel:xxxxxx");
- Intent it = new Intent(Intent.ACTION_DIAL, uri);
