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:[email protected]"); 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, "[email protected]");    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={"[email protected]"};      String[] ccs={"[email protected]"};      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 Uri uninstallUri = Uri.fromParts("package", "xxx", null); returnIt = new Intent(Intent.ACTION_DELETE, uninstallUri); 复制代码 install apk Uri installUri = Uri.fromParts("package", "xxx", null); returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri); 复制代码 play audio Uri playUri = Uri.parse("file:///sdcard/download/everything.mp3"); returnIt = new Intent(Intent.ACTION_VIEW, playUri); 复制代码 //发送附件 Intent it = new Intent(Intent.ACTION_SEND);   it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");   it.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/eoe.mp3");   sendIntent.setType("audio/mp3");   startActivity(Intent.createChooser(it, "Choose Email Client")); //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   //by clicking on your application on Market home   //page, and notice the ID from the address bar     /**      * 获得包安装Intent      * @param tempFile      * @return      */     public static Intent getPackageInstallIntent(File tempFile)     {         Uri mPackageURI = Uri.fromFile(tempFile);         Intent in = new Intent();         in.setAction(Intent.ACTION_VIEW);         in.addCategory(Intent.CATEGORY_DEFAULT);         in                 .setComponent(new ComponentName(                         "com.android.packageinstaller",                         "com.android.packageinstaller.PackageInstallerActivity"));         in.setDataAndType(mPackageURI,                 "application/vnd.android.package-archive");         in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);         return in;     }
