通過Intent跳轉到系統應用

撥號界面，代碼如下：
Intent intent =new Intent();

intent.setAction("android.intent.action.CALL_BUTTON");

startActivity(intent);
複製代碼
和
Uri uri = Uri.parse("tel:xxxxxx");

Intent intent = new Intent(Intent.ACTION_DIAL, uri);

startActivity(intent);
複製代碼
兩者都行
但是如果是跳轉到應用,使用一下代碼：
Intent intent= new Intent("android.intent.action.DIAL");

intent.setClassName("com.android.contacts","com.android.contacts.DialtactsActivity");
複製代碼
到通話記錄界面：
Intent intent=new Intent();

intent.setAction(Intent.ACTION_CALL_BUTTON);

startActivity(intent);
複製代碼
到聯繫人界面：
Intent intent = new Intent();

intent.setAction(Intent.ACTION_VIEW);

intent.setData(Contacts.People.CONTENT_URI);

startActivity(intent);
複製代碼
同理，到應用：
Intent intent= new Intent("com.android.contacts.action.LIST_STREQUENT");

intent.setClassName("com.android.contacts","com.android.contacts.DialtactsActivity");
複製代碼
調用聯繫人界面：
Intent intent = new Intent();

intent.setAction(Intent.ACTION_PICK);

intent.setData(Contacts.People.CONTENT_URI);

startActivity(intent);
複製代碼
插入聯繫人
Intent intent=new Intent(Intent.ACTION_EDIT,Uri.parse("content://com.android.contacts/contacts/"+"1"));

startActivity(intent);
複製代碼
到聯繫人列表界面
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);
複製代碼
到短信界面：
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);
複製代碼
到應用：
Intent intent = new Intent("android.intent.action.CONVERSATION");

startActivity(intent);
複製代碼

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

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

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

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");

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());
