android调用平台功能

一些例子是从网上找的，他有点像J2ME的platformRequest，能调用手机平台的一些如SMS，浏览器，MMS，TEL等功能

显示网页

Uri uri = Uri.parse("http://google.com"); Intent it = new Intent(Intent.ACTION_VIEW, uri); startActivity(it);
显示地图

Uri uri = Uri.parse("geo:38.899533,-77.036476"); Intent it = new Intent(Intent.ACTION_VIEW, uri); startActivity(it); //其他 geo URI 範例 //geo:latitude,longitude //geo:latitude,longitude?z=zoom //geo:0,0?q=my+street+address //geo:0,0?q=business+near+city //google.streetview:cbll=lat,lng&cbp=1,yaw,,pitch,zoom&mz=mapZoom

拨打电话

//叫出撥號程式 Uri uri = Uri.parse("tel:0800000123"); Intent it = new Intent(Intent.ACTION_DIAL, uri); startActivity(it); //直接打電話出去 Uri uri = Uri.parse("tel:0800000123"); Intent it = new Intent(Intent.ACTION_CALL, uri); startActivity(it); //用這個，要在 AndroidManifest.xml 中，加上 //<uses-permission id="android.permission.CALL_PHONE" />
发送SMS/MMS

//需写号码SMS Intent it = new Intent(Intent.ACTION_VIEW); it.putExtra("sms_body", "The SMS text"); it.setType("vnd.android-dir/mms-sms"); startActivity(it); //发送SMS Uri uri = Uri.parse("smsto:0800000123"); Intent it = new Intent(Intent.ACTION_SENDTO, uri); it.putExtra("sms_body", "The SMS text"); startActivity(it); //发送MMS 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);
发送EMAIL

Uri uri = Uri.parse("mailto:xxx@abc.com"); Intent it = new Intent(Intent.ACTION_SENDTO, uri); startActivity(it); Intent it = new Intent(Intent.ACTION_SEND); it.putExtra(Intent.EXTRA_EMAIL, "me@abc.com"); it.putExtra(Intent.EXTRA_TEXT, "The email body text"); it.setType("text/plain"); startActivity(Intent.createChooser(it, "Choose Email Client")); Intent it=new Intent(Intent.ACTION_SEND); String[] tos={"me@abc.com"}; String[] ccs={"you@abc.com"}; 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")); //传送附件 Intent it = new Intent(Intent.ACTION_SEND); it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text"); it.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/mysong.mp3"); sendIntent.setType("audio/mp3"); startActivity(Intent.createChooser(it, "Choose Email Client"));
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); Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1"); Intent it = new Intent(Intent.ACTION_VIEW, uri); startActivity(it);
Android Market

//寻找应用 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 //显示应用详细列表 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
卸载应用

Uri uri = Uri.fromParts("package", strPackageName, null); Intent it = new Intent(Intent.ACTION_DELETE, uri); startActivity(it);
安装应用

Uri uri = Uri.parse("url_of_apk_file"); Intent it = new Intent(Intent.ACTION_VIEW, uri); it.setData(uri); it.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); it.setClassName("com.android.packageinstaller", "com.android.packageinstaller.PackageInstallerActivity"); startActivity(it); //make sure the url_of_apk_file is readable for all users
