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"); Intent it = new Intent(Intent.ACTION_SENDTO, uri); it.putExtra("sms_body", "The SMS text"); startActivity(it); 复制代码 发送彩信 Uri uri = Uri.parse("content://media/external/images/media/23"); Intent it = new Intent(Intent.ACTION_SEND); it.putExtra("sms_body", "some text"); it.putExtra(Intent.EXTRA_STREAM, uri); it.setType("image/png"); startActivity(it); 复制代码 发送Email Uri uri = Uri.parse("mailto:[e-mail]"); Intent it = new Intent(Intent.ACTION_SENDTO, uri); startActivity(it); 复制代码 Intent it = new Intent(Intent.ACTION_SEND); it.putExtra(Intent.EXTRA_EMAIL, "[e-mail]"); it.putExtra(Intent.EXTRA_TEXT, "The email body text"); it.setType("text/plain"); startActivity(Intent.createChooser(it, "Choose Email Client")); 复制代码 Intent it=new Intent(Intent.ACTION_SEND); String[] tos={"[e-mail]"}; String[] ccs={"[e-mail]"}; it.putExtra(Intent.EXTRA_EMAIL, tos); it.putExtra(Intent.EXTRA_CC, ccs); it.putExtra(Intent.EXTRA_TEXT, "The email body text"); it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text"); it.setType("message/rfc822"); startActivity(Intent.createChooser(it, "Choose Email Client")); 复制代码 添加附件 Intent it = new Intent(Intent.ACTION_SEND); it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text"); it.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/mysong.mp3"); sendIntent.setType("audio/mp3"); startActivity(Intent.createChooser(it, "Choose Email Client")); 复制代码 播放多媒体 Intent it = new Intent(Intent.ACTION_VIEW); Uri uri = Uri.parse("file:///sdcard/song.mp3"); it.setDataAndType(uri, "audio/mp3"); startActivity(it); 复制代码 Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1"); Intent it = new Intent(Intent.ACTION_VIEW, uri); startActivity(it); 复制代码 Uninstall 程序 Uri uri = Uri.fromParts("package", strPackageName, null); Intent it = new Intent(Intent.ACTION_DELETE, uri); startActivity(it); 复制代码

uninstall apk

1. Uri uninstallUri = Uri.fromParts("package", "xxx", null);
2. returnIt = new Intent(Intent.ACTION_DELETE, uninstallUri);

复制代码

install apk

1. Uri installUri = Uri.fromParts("package", "xxx", null);
2. returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri);

复制代码

play audio

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

复制代码

1. //发送附件
2. Intent it = new Intent(Intent.ACTION_SEND);
3. it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");
4. it.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/eoe.mp3");
5. sendIntent.setType("audio/mp3");
6. startActivity(Intent.createChooser(it, "Choose Email Client"));

1. //搜索应用
2. Uri uri = Uri.parse("market://search?q=pname:pkg_name");
3. Intent it = new Intent(Intent.ACTION_VIEW, uri);
4. startActivity(it);
5. //where pkg_name is the full package path for an application
6. //显示指定应用的详细页面（这个好像不支持了，找不到app_id）
7. Uri uri = Uri.parse("market://details?id=app_id");
8. Intent it = new Intent(Intent.ACTION_VIEW, uri);
9. startActivity(it);
10. //where app_id is the application ID, find the ID
11. //by clicking on your application on Market home
12. //page, and notice the ID from the address bar
