11: Using PIM applications

Use tasks

Task Steps

Open a task list. >Invoke PIM.openPIMList() and provide as parameters the type of list to open

(

PIM.TODO_LIST) and the access mode with which to open the list (READ_WRITE, READ_ONLY,

or WRITE_ONLY).

ToDoList todoList = null;

try {

todoList = (ToDoList)PIM.getInstance().openPIMList(PIM.TODO_LIST,

PIM.READ_WRITE);

} catch (PimException e) {

//an error occurred

return;

}

Create a task. >Invoke createToDo() on a task list.

ToDo task = todoList.createToDo();

Add task information. 1. Before you set or retrieve a field, verify that the item supports the field by invoking

isSupportedField(int).

2. To retrieve the field data type, invoke PIMList.getFieldDataType(int).

3. To set the field data, invoke one of the following methods:

• addString()

• addDate()

• addInt()

• addBoolean()

• addBinary()

if (todoList.isSupportedField(ToDo.SUMMARY)) {

task.addString(ToDo.SUMMARY, ToDo.ATTR_NONE, "Create project plan");

}

if (todoList.isSupportedField(ToDo.DUE)) {

Date date = new Date();

task.addDate(ToDo.DUE, ToDo.ATTR_NONE, (date + 17280000));

}

if (todoList.isSupportedField(ToDo.NOTE)) {

task.addString(ToDo.NOTE, ToDo.ATTR_NONE, "Required for meeting");

}

if (todoList.isSupportedField(ToDo.PRIORITY)) {

task.addInt(Todo.PRIORITY, ToDo.ATTR_NONE, 2);

}

Set the status of a task.

> Use the PIM extended field ToDo.EXTENDED_FIELD_MIN_VALUE + 9:

• STATUS_NOT_STARTED: 1

• STATUS_IN_PROGRESS: 2

• STATUS_COMPLETED: 3

• STATUS_WAITING: 4

task.addInt(ToDo.EXTENDED_FIELD_MIN_VALUE + 9, ToDo.ATTR_NONE, 2);
