Android調用系統的庫

現在開發中的功能需要直接跳轉到撥號、聯繫人、短信界面等等，查找了很多資料，自己整理了一下。

首先，我們先看撥號界面，代碼如下：

Intent intent =new Intent();
intent.setAction("android.intent.action.CALL_BUTTON");
startActivity(intent);

Intent intent =new Intent();
        	intent.setAction("android.intent.action.CALL_BUTTON");
        	startActivity(intent);

和

[java] view plain copy print ?

Uri uri = Uri.parse("tel:xxxxxx");
Intent intent = new Intent(Intent.ACTION_DIAL, uri);
startActivity(intent);

Uri uri = Uri.parse("tel:xxxxxx"); 
Intent intent = new Intent(Intent.ACTION_DIAL, uri);   
startActivity(intent);

兩者都行

但是如果是跳轉到應用,使用一下代碼：

[java] view plain copy print ?

Intent intent= new Intent("android.intent.action.DIAL");
intent.setClassName("com.android.contacts","com.android.contacts.DialtactsActivity");

Intent intent= new Intent("android.intent.action.DIAL"); 
intent.setClassName("com.android.contacts","com.android.contacts.DialtactsActivity");

到通話記錄界面：

[java] view plain copy print ?

Intent intent=new Intent();
intent.setAction(Intent.ACTION_CALL_BUTTON);
startActivity(intent);

Intent intent=new Intent();
intent.setAction(Intent.ACTION_CALL_BUTTON);
startActivity(intent);

到聯繫人界面：

[java] view plain copy print ?

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(Contacts.People.CONTENT_URI);
startActivity(intent);

Intent intent = new Intent(); 
intent.setAction(Intent.ACTION_VIEW); 
intent.setData(Contacts.People.CONTENT_URI); 
startActivity(intent);

同理，到應用：

[java] view plain copy print ?

Intent intent= new Intent("com.android.contacts.action.LIST_STREQUENT");
intent.setClassName("com.android.contacts","com.android.contacts.DialtactsActivity");

Intent intent= new Intent("com.android.contacts.action.LIST_STREQUENT"); 
intent.setClassName("com.android.contacts","com.android.contacts.DialtactsActivity");

調用聯繫人界面：

[java] view plain copy print ?

Intent intent = new Intent();
intent.setAction(Intent.ACTION_PICK);
intent.setData(Contacts.People.CONTENT_URI);
startActivity(intent);

Intent intent = new Intent(); 
intent.setAction(Intent.ACTION_PICK); 
intent.setData(Contacts.People.CONTENT_URI); 
startActivity(intent);

插入聯繫人

[java] view plain copy print ?

Intent intent=new Intent(Intent.ACTION_EDIT,Uri.parse("content://com.android.contacts/contacts/"+"1"));
startActivity(intent);

  Intent intent=new Intent(Intent.ACTION_EDIT,Uri.parse("content://com.android.contacts/contacts/"+"1"));
  startActivity(intent);

到聯繫人列表界面

[java] view plain copy print ?

Intent intent = new Intent(Intent.ACTION_INSERT_OR_EDIT);
intent.setType("vnd.android.cursor.item/person");
intent.setType("vnd.android.cursor.item/contact");
intent.setType("vnd.android.cursor.item/raw_contact");
intent.putExtra(android.provider.ContactsContract.Intents.Insert.NAME, name);
intent.putExtra(android.provider.ContactsContract.Intents.Insert.COMPANY,company);
intent.putExtra(android.provider.ContactsContract.Intents.Insert.PHONE, tel);
intent.putExtra(android.provider.ContactsContract.Intents.Insert.PHONE_TYPE, 3);

Intent intent = new Intent(Intent.ACTION_INSERT_OR_EDIT);
			intent.setType("vnd.android.cursor.item/person");
			intent.setType("vnd.android.cursor.item/contact");
			intent.setType("vnd.android.cursor.item/raw_contact");
			intent.putExtra(android.provider.ContactsContract.Intents.Insert.NAME, name);
			intent.putExtra(android.provider.ContactsContract.Intents.Insert.COMPANY,company);
			intent.putExtra(android.provider.ContactsContract.Intents.Insert.PHONE, tel);
			intent.putExtra(android.provider.ContactsContract.Intents.Insert.PHONE_TYPE, 3);

到短信界面：

[java] view plain copy print ?

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setType("vnd.android-dir/mms-sms");
// intent.setData(Uri.parse("content://mms-sms/conversations/"));//此爲號碼
startActivity(intent);

Intent intent = new Intent(Intent.ACTION_VIEW);
				intent.setType("vnd.android-dir/mms-sms");
//				intent.setData(Uri.parse("content://mms-sms/conversations/"));//此爲號碼
				startActivity(intent);

到應用：

[java] view plain copy print ?

Intent intent = new Intent("android.intent.action.CONVERSATION");
startActivity(intent);

Intent intent = new Intent("android.intent.action.CONVERSATION");
startActivity(intent);

以下是在網上找到的其他方法：

1.從google搜索內容

[java] view plain copy print ?

Intent intent = new Intent();
intent.setAction(Intent.ACTION_WEB_SEARCH);
intent.putExtra(SearchManager.QUERY,"searchString")
startActivity(intent);

Intent intent = new Intent(); 
intent.setAction(Intent.ACTION_WEB_SEARCH); 
intent.putExtra(SearchManager.QUERY,"searchString") 
startActivity(intent);

2.瀏覽網頁

[java] view plain copy print ?

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

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

3.顯示地圖

[java] view plain copy print ?

Uri uri = Uri.parse("geo:38.899533,-77.036476");
Intent it = new Intent(Intent.Action_VIEW,uri);
startActivity(it);

Uri uri = Uri.parse("geo:38.899533,-77.036476"); 
Intent it = new Intent(Intent.Action_VIEW,uri); 
startActivity(it);

4.路徑規劃

[java] view plain copy print ?

Uri uri = Uri.parse("http://maps.google.com/maps?f=dsaddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");
Intent it = new Intent(Intent.ACTION_VIEW,URI);
startActivity(it);

Uri uri = Uri.parse("http://maps.google.com/maps?f=dsaddr=startLat%20startLng&daddr=endLat%20endLng&hl=en"); 
Intent it = new Intent(Intent.ACTION_VIEW,URI); 
startActivity(it);

5.撥打電話

[java] view plain copy print ?

Uri uri = Uri.parse("tel:xxxxxx");
Intent it = new Intent(Intent.ACTION_DIAL, uri);
startActivity(it);

Uri uri = Uri.parse("tel:xxxxxx"); 
Intent it = new Intent(Intent.ACTION_DIAL, uri);   
startActivity(it);

和

[java] view plain copy print ?

uri = Uri.parse("tel:"+number);
intent = new Intent(Intent.ACTION_CALL,uri);
startActivity(intent);

uri = Uri.parse("tel:"+number);  
                intent = new Intent(Intent.ACTION_CALL,uri);  
                startActivity(intent);

其中不同自己試驗一下就知道了。

         startActivityForResult(inttPhoto, 10);

14.從gallery選取圖片

[java] view plain copy print ?

Intent i = new Intent();
i.setType("image/*");
i.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(i, 11);

 Intent i = new Intent(); 
         i.setType("image/*"); 
         i.setAction(Intent.ACTION_GET_CONTENT); 
         startActivityForResult(i, 11);

15. 打開錄音機

[java] view plain copy print ?

Intent mi = new Intent(Media.RECORD_SOUND_ACTION);
startActivity(mi);

Intent mi = new Intent(Media.RECORD_SOUND_ACTION); 
         startActivity(mi);

16.顯示應用詳細列表

[java] view plain copy print ?

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

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

剛纔找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

[java] view plain copy print ?

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

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

18打開聯繫人列表

[java] view plain copy print ?

<1>
Intent i = new Intent();
i.setAction(Intent.ACTION_GET_CONTENT);
i.setType("vnd.android.cursor.item/phone");
startActivityForResult(i, REQUEST_TEXT);

 <1>           
          Intent i = new Intent(); 
          i.setAction(Intent.ACTION_GET_CONTENT); 
          i.setType("vnd.android.cursor.item/phone"); 
          startActivityForResult(i, REQUEST_TEXT);

[java] view plain copy print ?

<2>
Uri uri = Uri.parse("content://contacts/people");
Intent it = new Intent(Intent.ACTION_PICK, uri);
startActivityForResult(it, REQUEST_TEXT);

<2> 
         Uri uri = Uri.parse("content://contacts/people"); 
         Intent it = new Intent(Intent.ACTION_PICK, uri); 
         startActivityForResult(it, REQUEST_TEXT);

19 打開另一程序

[java] view plain copy print ?

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);

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 添加到短信收件箱

ContentValues cv = new ContentValues();      

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

cv.put("address","短信地址");  

cv.put("body", "短信內容");   

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

21 從sim卡或者聯繫人中查詢

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);}

查看某個聯繫人，當然這裏是ACTION_VIEW，如果爲選擇並返回action改爲ACTION_PICK，當然處理intent時返回需要用到 startActivityforResult

Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, ID);//最後的ID參數爲聯繫人Provider中的數據庫BaseID，即哪一行

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

22 刪除

uri = ContentUris.withAppendedId(People.CONTENT_URI, 聯繫人id);  

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

23 添加到聯繫人：

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, "自定義聯繫人名");  

                    operationList.add(builder.build());  

                    builder = ContentProviderOperation.newInsert(Data.CONTENT_URI);  

                    builder.withValueBackReference(Phone.RAW_CONTACT_ID, 0);  

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

                    builder.withValue(Phone.NUMBER, "聯繫人的phonenumber");  

                    builder.withValue(Data.IS_PRIMARY, 1);  

                    operationList.add(builder.build());  

                    try {  

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

                    } catch (RemoteException e) {  

                        e.printStackTrace();   

                    } catch (OperationApplicationException e) {  

                        e.printStackTrace();   

                    }

23 選擇一個圖片

[java] view plain copy print ?

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
startActivityForResult(intent, 0);

Intent intent = new Intent(Intent.ACTION_GET_CONTENT); 
intent.addCategory(Intent.CATEGORY_OPENABLE);
 intent.setType("image/*");
 startActivityForResult(intent, 0);

24 調用Android設備的照相機，並設置拍照後存放位置

[java] view plain copy print ?

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment .getExternalStorageDirectory().getAbsolutePath()+"/cwj", android123 + ".jpg"))); //存放位置爲sdcard卡上cwj文件夾，文件名爲android123.jpg格式
startActivityForResult(intent, 0);

 Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
 intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment .getExternalStorageDirectory().getAbsolutePath()+"/cwj", android123 + ".jpg"))); //存放位置爲sdcard卡上cwj文件夾，文件名爲android123.jpg格式
 startActivityForResult(intent, 0);

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

[java] view plain copy print ?

Uri uri = Uri.parse("market://search?q=pname:com.android123.cwj");
Intent intent = new Intent(Intent.ACTION_VIEW, uri); startActivity(intent);

Uri uri = Uri.parse("market://search?q=pname:com.android123.cwj");
 Intent intent = new Intent(Intent.ACTION_VIEW, uri); startActivity(intent);

26 獲取文件信息，並使用相對應軟件打開

[java] view plain copy print ?

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,
