Intent 大全完整版

1.Intent的用法：

(1)用Action跳轉

1、使用Action跳轉，如果有一個程式的AndroidManifest.xml中的某一個 Activity的IntentFilter段中 定義了包含了相同的Action那麼這個Intent就與這個目标Action比對。如果這個IntentFilter段中沒有定義 Type,Category，那麼這個 Activity就比對了。但是如果手機中有兩個以上的程式比對，那麼就會彈出一個對話可框來提示說明。

Action 的值在Android中有很多預定義，如果你想直接轉到你自己定義的Intent接收者，你可以在接收者的IntentFilter 中加入一個自定義的Action值（同時要設定 Category值為"android.intent.category.DEFAULT"），在你的Intent中設定該值為Intent的 Action,就直接能跳轉到你自己的Intent接收者中。因為這個Action在系統中是唯一的。

2,data/type，你可以用Uri 來做為data,比如Uri uri = Uri.parse(http://www.google.com);

Intent i = new Intent(Intent.ACTION_VIEW,uri);手機的Intent分發過程中，會根據http://www.google.com 的scheme判斷出資料類型type 。手機的Brower則能比對它，在Brower的Manifest.xml中的IntenFilter中 首先有ACTION_VIEW Action,也能處理http:的type，

3， 至于分類Category，一般不要去在Intent中設定它，如果你寫Intent的接收者，就在Manifest.xml的Activity的 IntentFilter中包含android.category.DEFAULT,這樣所有不設定 Category（Intent.addCategory(String c);）的Intent都會與這個Category比對。

4,extras（附 加資訊），是其它所有附加資訊的集合。使用extras可以為元件提供擴充資訊，比如，如果要執行“發送電子郵件”這個動 作，可以将電子郵件的标題、正文等儲存在extras裡，傳給電子郵件發送元件。

（2）用類名跳轉

    Intent負責對應用中一次操作的動作、動作涉及資料、附加資料進行描 述，Android則根據此Intent的描述， 負責找到對應的元件，将 Intent傳遞給調用的元件，并完成元件的調用。Intent在這裡起着實作調用者與被調用者之間的解耦作用。Intent傳遞過程中，要找 到目标消費者（另一個Activity,IntentReceiver或Service），也就是Intent的響 應者。

Intent intent = new Intent();

intent.setClass(context, targetActivy.class);

//或者直接用 Intent intent = new Intent(context, targetActivity.class);

startActivity(intent);

不過注意用類名跳轉，需要在AndroidManifest.xml中申明activity  

<activity android:name="targetActivity"></activity>

2.幾種Intent的用法

android 中intent是經常要用到的。不管是頁面牽轉，還是傳遞資料，或是調用外部程式，系統功能都要用到intent。在做了一些intent的例子之後，整理了一下intent，希望對大家有用。由于intent内容太多，不可能真的寫全，難免會有遺落，以後我會随時更新。如果你們有疑問或新的intent内容，希望交流。

intent大全：

//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      

剛才找app id未果，結果發現用package name也可以

Uri uri = Uri.parse("market://details?id=<packagename>");

這個簡單多了

17尋找應用      

Uri uri = Uri.parse("market://search?q=pname:pkg_name");         

//where pkg_name is the full package path for an application      

18打開聯系人清單

            <1>            

                    Intent i = new Intent();

           i.setAction(Intent.ACTION_GET_CONTENT);

           i.setType("vnd.android.cursor.item/phone");

           startActivityForResult(i, REQUEST_TEXT);

            <2>

                Uri uri = Uri.parse("content://contacts/people");

            Intent it = new Intent(Intent.ACTION_PICK, uri);

            startActivityForResult(it, REQUEST_TEXT);

19 打開另一程式

Intent i = new Intent();

            ComponentName cn = new ComponentName("com.yellowbook.android2",

                    "com.yellowbook.android2.AndroidSearch");

            i.setComponent(cn);

            i.setAction("android.intent.action.MAIN");

            startActivityForResult(i, RESULT_OK);

20.調用系統編輯添加聯系人（高版本SDK有效）：

Intent it = newIntent(Intent.ACTION_INSERT_OR_EDIT);

               it.setType("vnd.android.cursor.item/contact");

                //it.setType(Contacts.CONTENT_ITEM_TYPE);

                it.putExtra("name","myName");

               it.putExtra(android.provider.Contacts.Intents.Insert.COMPANY,  "organization");

               it.putExtra(android.provider.Contacts.Intents.Insert.EMAIL,"email");

                it.putExtra(android.provider.Contacts.Intents.Insert.PHONE,"homePhone");

                it.putExtra(android.provider.Contacts.Intents.Insert.SECONDARY_PHONE,

                               "mobilePhone");

                it.putExtra(  android.provider.Contacts.Intents.Insert.TERTIARY_PHONE,

                               "workPhone");

               it.putExtra(android.provider.Contacts.Intents.Insert.JOB_TITLE,"title");

                startActivity(it);

21.調用系統編輯添加聯系人（全有效）：

Intent intent = newIntent(Intent.ACTION_INSERT_OR_EDIT);

           intent.setType(People.CONTENT_ITEM_TYPE);

           intent.putExtra(Contacts.Intents.Insert.NAME, "My Name");

           intent.putExtra(Contacts.Intents.Insert.PHONE, "[phone]");

           intent.putExtra(Contacts.Intents.Insert.PHONE_TYPE,Contacts.PhonesColumns.TYPE_MOBILE);

           intent.putExtra(Contacts.Intents.Insert.EMAIL, "[email protected]");

           intent.putExtra(Contacts.Intents.Insert.EMAIL_TYPE,                    Contacts.ContactMethodsColumns.TYPE_WORK);

           startActivity(intent);

                cv.put("type", "1");  

cv.put("address","短信位址"); 

cv.put("body", "短信内容");  

getContentResolver().insert(Uri.parse("content://sms/inbox"), cv);

21 從sim卡或者聯系人中查詢

Cursor cursor; 

        Uri uri; 

        if (type == 1) { 

            Intent intent = new Intent(); 

            intent.setData(Uri.parse("content://icc/adn")); 

            uri = intent.getData(); 

        } else 

            uri = People.CONTENT_URI; 

        cursor = activity.getContentResolver().query(uri, null, null, null, null); 

while (cursor.moveToNext()) { 

int peopleId = cursor.getColumnIndex(People._ID);

int nameId = cursor.getColumnIndex(People.NAME);

int phoneId = cursor.getColumnIndex(People.NUMBER);}

檢視某個聯系人，當然這裡是ACTION_VIEW，如果為選擇并傳回action改為ACTION_PICK，當然處理intent時傳回需要用到 startActivityforResult

Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, ID);//最後的ID參數為聯系人Provider中的資料庫BaseID，即哪一行

Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setData(personUri); startActivity(intent);

22 删除

uri = ContentUris.withAppendedId(People.CONTENT_URI, 聯系人id); 

        int count = activity.getContentResolver().delete(uri, null, null

23 添加到聯系人：

ContentValues cv = new ContentValues(); 

                    ArrayList<ContentProviderOperation> operationList = new ArrayList<ContentProviderOperation>(); 

                    ContentProviderOperation.Builder builder = ContentProviderOperation.newInsert(RawContacts.CONTENT_URI); 

                    builder.withValues(cv); 

                    operationList.add(builder.build()); 

                    builder = ContentProviderOperation.newInsert(Data.CONTENT_URI); 

                    builder.withValueBackReference(StructuredName.RAW_CONTACT_ID, 0); 

                    builder.withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE); 

                    builder.withValue(StructuredName.DISPLAY_NAME, "自定義聯系人名"); 

                    builder.withValueBackReference(Phone.RAW_CONTACT_ID, 0); 

                    builder.withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE); 

                    builder.withValue(Phone.NUMBER, "聯系人的phonenumber"); 

                    builder.withValue(Data.IS_PRIMARY, 1); 

                    try { 

                        getContentResolver().applyBatch(ContactsContract.AUTHORITY, operationList); 

                    } catch (RemoteException e) { 

                        e.printStackTrace(); 

                    } catch (OperationApplicationException e) { 

                    }  

23 選擇一個圖檔

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);  

intent.addCategory(Intent.CATEGORY_OPENABLE); 

intent.setType("image/*"); 

startActivityForResult(intent, 0);   

24 調用

Android

裝置的照相機，并設定拍照後存放位置

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 

intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment .getExternalStorageDirectory().getAbsolutePath()+"/cwj", android123 + ".jpg"))); //存放位置為sdcard卡上cwj檔案夾，檔案名為android123.jpg格式 

startActivityForResult(intent, 0);  

25 在market上搜尋指定package name，比如搜尋com.android123.cwj的寫法如下

Uri uri = Uri.parse("market://search?q=pname:com.android123.cwj"); 

Intent intent = new Intent(Intent.ACTION_VIEW, uri); startActivity(intent);

26擷取檔案資訊，并使用相對應軟體打開

private void openFile(File f)   

{   

   Intent intent = new Intent();   

   intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);   

   intent.setAction(android.content.Intent.ACTION_VIEW);   

   String type = getMIMEType(f);   

   intent.setDataAndType(Uri.fromFile(f), type);   

   startActivity(intent);   

}   

private String getMIMEType(File f){   

   String end = f   

       .getName()   

       .substring(f.getName().lastIndexOf(".") + 1,   

           f.getName().length()).toLowerCase();   

   String type = "";   

   if (end.equals("mp3") || end.equals("aac") || end.equals("aac")   

       || end.equals("amr") || end.equals("mpeg")   

       || end.equals("mp4"))   

   {   

     type = "audio";   

   } else if (end.equals("jpg") || end.equals("gif")   

       || end.equals("png") || end.equals("jpeg"))   

     type = "image";   

   } else   

     type = "*";   

   }   

   type += "/*";   

   return type;
