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。
插入联系人
[java] view plain copy print ?
以下是在网上找到的其他方法: 1.从google搜索内容
[java] view plain copy print ?
[java] view plain copy print ?
25在market上搜索指定package name,比如搜索com.android123.cwj的写法如下 [java] view plain copy print ?
首先,我们先看拨号界面,代码如下:
[java] view plain copy print ?
- Intentintent=newIntent();
- intent.setAction("android.intent.action.CALL_BUTTON");
- startActivity(intent);
Intent intent =new Intent(); intent.setAction("android.intent.action.CALL_BUTTON"); startActivity(intent);
和
- Uriuri=Uri.parse("tel:xxxxxx");
- Intentintent=newIntent(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 plain copy print ?
- Intentintent=newIntent("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 plain copy print ?
- Intentintent=newIntent();
- intent.setAction(Intent.ACTION_CALL_BUTTON);
- startActivity(intent);
Intent intent=new Intent();intent.setAction(Intent.ACTION_CALL_BUTTON);startActivity(intent);
[java] view plain copy print ?
- Intentintent=newIntent();
- 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 plain copy print ?- Intentintent=newIntent("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 plain copy print ?
- Intentintent=newIntent();
- 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 plain copy print ?
- Intentintent=newIntent(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 plain copy print ?- Intentintent=newIntent(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 ?
- Intentintent=newIntent(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 plain copy print ?
- Intentintent=newIntent("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 plain copy print ? - Intentintent=newIntent();
- 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 plain copy print ? - Uriuri=Uri.parse("http://www.google.com");
- Intentit=newIntent(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 plain copy print ? - Uriuri=Uri.parse("geo:38.899533,-77.036476");
- Intentit=newIntent(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 plain copy print ? - Uriuri=Uri.parse("http://maps.google.com/maps?f=dsaddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");
- Intentit=newIntent(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 plain copy print ? - Uriuri=Uri.parse("tel:xxxxxx");
- Intentit=newIntent(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=newIntent(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。

和
[java] view plain copy print ? - uri=Uri.parse("smsto:"+要发送短信的对方的number);
- intent=newIntent(Intent.ACTION_SENDTO,uri);
- startActivity(intent);
uri = Uri.parse("smsto:"+要发送短信的对方的number); intent = new Intent(Intent.ACTION_SENDTO,uri); startActivity(intent);
和 [java] view plain copy print ? - mIntent=newIntent(Intent.ACTION_VIEW);
- mIntent.putExtra("address",c.getString(c.getColumnIndex(column)));
- mIntent.setType("vnd.android-dir/mms-sms");
- startActivity(mIntent);
mIntent = new Intent(Intent.ACTION_VIEW); mIntent.putExtra("address", c.getString(c.getColumnIndex(column))); mIntent.setType("vnd.android-dir/mms-sms"); startActivity(mIntent);

14.从gallery选取图片
[java] view plain copy print ? - Intenti=newIntent();
- 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);

- //whereapp_idistheapplicationID,findtheID
- //byclickingonyourapplicationonMarkethome
- //page,andnoticetheIDfromtheaddressbar<SPANstyle="FONT-FAMILY:Simsun;WHITE-SPACE:normal;BACKGROUND-COLOR:rgb(255,255,255)"></SPAN>
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
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 plain copy print ? - Uriuri=Uri.parse("market://search?q=pname:pkg_name");
- Intentit=newIntent(Intent.ACTION_VIEW,uri);
- startActivity(it);
- //wherepkg_nameisthefullpackagepathforanapplication<SPANstyle="FONT-FAMILY:Simsun;WHITE-SPACE:normal;BACKGROUND-COLOR:rgb(255,255,255)"></SPAN>
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 plain copy print ? - <1>
- Intenti=newIntent();
- 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>
- Uriuri=Uri.parse("content://contacts/people");
- Intentit=newIntent(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 plain copy print ? - Intenti=newIntent();
- ComponentNamecn=newComponentName("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
- ContentValuescv=newContentValues();
- 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
- Cursorcursor;
- Uriuri;
- if(type==1){
- Intentintent=newIntent();
- 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()){
- intpeopleId=cursor.getColumnIndex(People._ID);
- intnameId=cursor.getColumnIndex(People.NAME);
- intphoneId=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);
- intcount=activity.getContentResolver().delete(uri,null,null);
23 添加到联系人:
- ContentValuescv=newContentValues();
- ArrayList<ContentProviderOperation>operationList=newArrayList<ContentProviderOperation>();
- ContentProviderOperation.Builderbuilder=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(RemoteExceptione){
- e.printStackTrace();
- }catch(OperationApplicationExceptione){
- e.printStackTrace();
- }
23选择一个图片
[java] view plain copy print ?
- Intentintent=newIntent(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 调用Android设备的照相机,并设置拍照后存放位置
[java] view plain copy print ?- Intentintent=newIntent(MediaStore.ACTION_IMAGE_CAPTURE);
- intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(newFile(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 plain copy print ?
- Uriuri=Uri.parse("market://search?q=pname:com.android123.cwj");
- Intentintent=newIntent(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 plain copy print ?
- privatevoidopenFile(Filef)
- {
- Intentintent=newIntent();
- intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
- intent.setAction(android.content.Intent.ACTION_VIEW);
- Stringtype=getMIMEType(f);
- intent.setDataAndType(Uri.fromFile(f),type);
- startActivity(intent);
- }
- privateStringgetMIMEType(Filef){
- Stringend=f
- .getName()
- .substring(f.getName().lastIndexOf(".")+1,
- f.getName().length()).toLowerCase();
- Stringtype="";
- if(end.equals("mp3")||end.equals("aac")||end.equals("aac")
- ||end.equals("amr")||end.equals("mpeg")
- ||end.equals("mp4"))
- {
- type="audio";
- }elseif(end.equals("jpg")||end.equals("gif")
- ||end.equals("png")||end.equals("jpeg"))
- {
- type="image";
- }else
- {
- type="*";
- }
- type+="/*";
- returntype;
- }
