Intent跳转到系统应用中的拨号界面、联系人界面、短信界面及其他

2013-08-20 15:02 489 查看
现在开发中的功能需要直接跳转到拨号、联系人、短信界面等等,查找了很多资料,自己整理了一下。

         首先,我们先看拨号界面,代码如下:

[java]
view plaincopyprint?

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 plaincopyprint?

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);

两者都行   

但是如果是跳转到应用,使用一下代码:

[java]
view plaincopyprint?

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");


          到通话记录界面:

[java]
view plaincopyprint?

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

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


            到联系人界面:

[java]
view plaincopyprint?

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,到应用:

[java]
view plaincopyprint?

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");


          调用联系人界面:

[java]
view plaincopyprint?

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);

          插入联系人

[java]
view plaincopyprint?

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);

             到联系人列表界面      

[java]
view plaincopyprint?

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 plaincopyprint?

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

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

到应用:

[java]
view plaincopyprint?

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

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


以下是在网上找到的其他方法:

1.从google搜索内容 

[java]
view plaincopyprint?

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.浏览网页 

[java]
view plaincopyprint?

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

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


3.显示地图 

[java]
view plaincopyprint?

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.路径规划 

[java]
view plaincopyprint?

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.拨打电话 

[java]
view plaincopyprint?

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);


[java]
view plaincopyprint?

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);


其中不同自己试验一下就知道了。 

6.调用发短信的程序 



[java]
view plaincopyprint?

Intent it = new Intent(Intent.ACTION_VIEW);

uri = Uri.parse("smsto:"+要发送短信的对方的number);
intent = new Intent(Intent.ACTION_SENDTO,uri);
startActivity(intent);


[java]

startActivity(it);
//where app_id is the application ID, find the ID
//by clicking on your application on Market home

刚才找app id未果,结果发现用package name也可以 Uri uri = Uri.parse("market://details?id=<packagename>"); 

这个简单多了 

17寻找应用      

[java]
view plaincopyprint?

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

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打开联系人列表 

        

[java]
view plaincopyprint?

<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 plaincopyprint?

<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 打开另一程序 

[java]
view plaincopyprint?

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", "短信内容");   

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

 

 

21 从sim卡或者联系人中查询

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, nullnullnullnull);
 

while (cursor.moveToNext()) {  

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

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

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

查看某个联系人,当然这里是ACTION_VIEW,如果为选择并返回action改为ACTION_PICK,当然处理intent时返回需要用到 startActivityforResult 

Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, ID);//最后的ID参数为联系人Provider中的数据库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, 联系人id);  

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

 

23 添加到联系人:

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, "自定义联系人名");  

                    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, "联系人的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();  

                    }

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


24 调用Android设备的照相机,并设置拍照后存放位置

[java]
view plaincopyprint?

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

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

[java]
view plaincopyprint?

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 获取文件信息,并使用相对应软件打开

[java]
view plaincopyprint?

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;    
 }
