Android(安卓)Phone Application Development(Part 1)

初步完成sample ap如附檔，第一個欄位為顯示業者名稱，第二欄位是電話號碼，下面為撥號鍵，其中主要是intent的使用。Intent 應該算是 Andorid 中特有的東西。你可以在 Intent 中，指定要應用程式執行的動作 (view, edit, dial)，以及應用程式執行該動作時，所需要的資料。都指定好後，只要透過 startActivity()，Android 系統會自動尋找，最符合你指定要求的應用程式，並喚起執行該應用程式。以下為網路上找到的Sample code:顯示網頁

Uriuri=Uri.parse("http://google.com");
Intentit=newIntent(Intent.ACTION_VIEW,uri);
startActivity(it);

顯示地圖

Uriuri=Uri.parse("geo:38.899533,-77.036476");
Intentit=newIntent(Intent.ACTION_VIEW,uri);
startActivity(it);
//其他geoURI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

路徑規劃

Uriuri=Uri.parse("http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");
Intentit=newIntent(Intent.ACTION_VIEW,uri);
startActivity(it);
//wherestartLat,startLng,endLat,endLngarealongwith6decimalslike:50.123456

撥打電話

//叫出撥號程式
Uriuri=Uri.parse("tel:0800000123");
Intentit=newIntent(Intent.ACTION_DIAL,uri);
startActivity(it);

//直接打電話出去
Uriuri=Uri.parse("tel:0800000123");
Intentit=newIntent(Intent.ACTION_CALL,uri);
startActivity(it);
//用這個，要在AndroidManifest.xml中，加上
//<uses-permissionid="android.permission.CALL_PHONE"/>

傳送 SMS/MMS

//叫起簡訊程式
Intentit=newIntent(Intent.ACTION_VIEW);
it.putExtra("sms_body","TheSMStext");
it.setType("vnd.android-dir/mms-sms");
startActivity(it);

//傳送簡訊
Uriuri=Uri.parse("smsto:0800000123");
Intentit=newIntent(Intent.ACTION_SENDTO,uri);
it.putExtra("sms_body","TheSMStext");
startActivity(it);

//傳送MMS
Uriuri=Uri.parse("content://media/external/images/media/23");
Intentit=newIntent(Intent.ACTION_SEND);
it.putExtra("sms_body","sometext");
it.putExtra(Intent.EXTRA_STREAM,uri);
it.setType("image/png");
startActivity(it);

傳送 Email

Uriuri=Uri.parse("mailto:xxx@abc.com");
Intentit=newIntent(Intent.ACTION_SENDTO,uri);
startActivity(it);

Intentit=newIntent(Intent.ACTION_SEND);
it.putExtra(Intent.EXTRA_EMAIL,"me@abc.com");
it.putExtra(Intent.EXTRA_TEXT,"Theemailbodytext");
it.setType("text/plain");
startActivity(Intent.createChooser(it,"ChooseEmailClient"));

Intentit=newIntent(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,"Theemailbodytext");
it.putExtra(Intent.EXTRA_SUBJECT,"Theemailsubjecttext");
it.setType("message/rfc822");
startActivity(Intent.createChooser(it,"ChooseEmailClient"));

//傳送附件檔
Intentit=newIntent(Intent.ACTION_SEND);
it.putExtra(Intent.EXTRA_SUBJECT,"Theemailsubjecttext");
it.putExtra(Intent.EXTRA_STREAM,"file:///sdcard/mysong.mp3");
sendIntent.setType("audio/mp3");
startActivity(Intent.createChooser(it,"ChooseEmailClient"));

播放多媒體

Intentit=newIntent(Intent.ACTION_VIEW);
Uriuri=Uri.parse("file:///sdcard/song.mp3");
it.setDataAndType(uri,"audio/mp3");
startActivity(it);

Uriuri=Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI,"1");
Intentit=newIntent(Intent.ACTION_VIEW,uri);
startActivity(it);

Market 相關

//尋找某個應用程式
Uriuri=Uri.parse("market://search?q=pname:pkg_name");
Intentit=newIntent(Intent.ACTION_VIEW,uri);
startActivity(it);
//wherepkg_nameisthefullpackagepathforanapplication

//顯示某應用程式詳細畫面
Uriuri=Uri.parse("market://details?id=app_id");
Intentit=newIntent(Intent.ACTION_VIEW,uri);
startActivity(it);
//whereapp_idistheapplicationID,findtheID
//byclickingonyourapplicationonMarkethome
//page,andnoticetheIDfromtheaddressbar

Uninstall 應用程式

Uriuri=Uri.fromParts("package",strPackageName,null);
Intentit=newIntent(Intent.ACTION_DELETE,uri);
startActivity(it);

安裝 APK 檔

Uriuri=Uri.parse("url_of_apk_file");
Intentit=newIntent(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);
//makesuretheurl_of_apk_fileisreadableforallusers
