there is the following objects:
public class Course {
private static int courseID = 0;
private String courseTitle;
private ArrayList<Assignment> assignments;
private Course(String title, ArrayList<Assignment> assns)
{
courseTitle = title;
assignments = assns;
courseID++;
}
//returns a Course instant with random assignment values
static public Course generateRandomCourse()
{
Random rnd = new Random();
int assignmentNo = rnd.nextInt(5);
ArrayList<Assignment> tempAssns = new ArrayList<Assignment>();
for(int i=0; i < assignmentNo; i++)
tempAssns.add(Assignment.generateRandomAssignment());
return new Course("Course " + courseID, tempAssns);
}
public String getCourseTitle() {return courseTitle;}
public ArrayList<Assignment> getAssignments() {return assignments;}
}
Course contains Assignment objects:
public class Assignment {
private static int assID = 0; //static ID increments with every new
private String assignmentTitle; //title of assignment
private int assignmentGrade; //grade of assignment
//private constructor. Increments ID.
private Assignment(String title, int grade)
{
assignmentTitle = title;
assignmentGrade = grade;
assID++;
}
//returns an Assignment instance with random values
static public Assignment generateRandomAssignment()
{
Random rnd = new Random();
String tempTitle = "Assignment " + assID;
int tempGrade = rnd.nextInt(100) + 1;
return new Assignment(tempTitle, tempGrade);
}
public String getAssignmentTitle() {return assignmentTitle; }
public int getAssignmentGrade() {return assignmentGrade;}
}
The data must be displayed in a list view as:
I am following this tutorial:https://www.tutorialspoint.com/android/android_list_view.htm. Following it, the activity has an array of strings, creates an adapter and links it to a Listwiew:
String[] mobileArray = {"Android","IPhone","WindowsMobile","Blackberry",
"WebOS","Ubuntu","Windows7","Max OS X"};
ArrayAdapter adapter = new ArrayAdapter<String>(this,
R.layout.activity_listview, mobileArray);
listView listView = (ListView) findViewById(R.id.mobile_list);
listView.setAdapter(adapter);
The xml file contains:
<ListView
android:id="@+id/mobile_list"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
The activity_listview.xml file contains:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/label"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dip"
android:textSize="16dip"
android:textStyle="bold" >
</TextView>
How to get Listview from:
ArrayList<Course>courses = new ArrayList<Course>()?
Is a vertical layout within the listview needed?
Update: Possible layout file course_row_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/coureTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"/>
<ListView
android:id="@+id/assignments"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
possible assignment layout file assignment_row_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/assignmentTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"/>
<TextView
android:id="@+id/cassignmentGrade"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"/>
</LinearLayout>
