Android Intent的几种用法全面总结

Intent, 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(“http://www.google.com“);

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(“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);

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);

startActivity(it);

复制代码

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” />

复制代码

发送SMS/MMS
调用发送短信的程序

Intent it = new Intent(Intent.ACTION_VIEW);

it.putExtra(“sms_body”, “The SMS text”);

it.setType(“vnd.android-dir/mms-sms”);

startActivity(it);

复制代码

发送短信

Uri uri = Uri.parse(“smsto:0800000123”);

复制代码

sendIntent.setType(“audio/mp3”);

startActivity(Intent.createChooser(it, “Choose Email Client”));

复制代码

Uri uninstallUri = Uri.fromParts(“package”, “xxx”, null);
returnIt = new Intent(Intent.ACTION_DELETE, uninstallUri);

复制代码

Uri installUri = Uri.fromParts(“package”, “xxx”, null);
returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri);

复制代码

Uri playUri = Uri.parse(“file:///sdcard/download/everything.mp3”);
returnIt = new Intent(Intent.ACTION_VIEW, playUri);

复制代码

//搜索应用
Uri uri = Uri.parse(“market://search?q=pname:pkg_name”);
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);
//where pkg_name is the full package path for an application
//显示指定应用的详细页面（这个好像不支持了，找不到app_id）
Uri uri = Uri.parse(“market://details?id=app_id”);
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);
//where app_id is the application ID, find the ID
