Android Intent的幾種用法全面總結

Intent, 用法

Intent應該算是Android中特有的東西。你可以在Intent中指定程式要執行的動作（比如：view,edit,dial），以及程式執行到該動作時所需要的資料。都指定好後，只要呼叫startActivity()，Android系統會自動尋找最符合你指定要求的應用程式，並執行該程式。

下面列出幾種Intent的用法
顯示網頁:

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

2. Intent it = new Intent(Intent.Action_VIEW,uri);
3. startActivity(it);

路徑規劃:

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);
