Question

I add menu’s in my application dynamically depending on the values i get from the back-end in the onPrepareOptionsMenu(Menu menu). Now i would want to decide the action that is to be performed for the menu added dynamically (as i do not know the action to be performed beforehand) depending on certain values that came associated with the menu from the back-end. How do i achieve this. Kindly provide me some ideas on this. Thanks in advance.

Answer 1

I found a way to achieve what i wanted. I put the values associated to the menu as a part of the MenuItems intent. In the onOptionsItemSelected(MenuItem item) i get the intent from the MenuItem retrieve the values from it and perform the action required. The code is as below:

 @Override
public boolean onPrepareOptionsMenu(Menu menu) {
    // TODO Auto-generated method stub
    ApplicationManager.getInstance().resetCounter();
    menu.removeGroup(1);
    Vector listOfMenuToBeAdded=Service.getInstance().getMenuList();
    Enumeration<com.data.Menu> menuEnumeration = listOfMenuToBeAdded.elements();
    while (menuEnumeration.hasMoreElements()) {
        com.data.Menu levelOptions = (com.pravaa.mobile.dashboard.data.Menu) menuEnumeration
                .nextElement();
        MenuItem levelMenuItem = menu.add(1, 100, Menu.NONE,
                levelOptions.getCaption());
        LevelOptionIntent levelOptionIntent = new LevelOptionIntent();
        levelOptionIntent.setAppCode(levelOptions.getAppCode());
        levelOptionIntent.setDashboardNumber(levelOptions.getNumber());
        levelOptionIntent.setUniqueRecordId(levelOptions
                    .getUniqueRecordId());
        levelOptionIntent.setLevelNumber(levelOptions.getLevelNo());    
        levelMenuItem.setIntent(levelOptionIntent);
    }
    return true;
}

Once a menu item is clicked on perform the action according to the values set in the intent.

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // TODO Auto-generated method stub
    switch (item.getItemId()) {
    case 100:
        LevelOptionIntent levelOptionIntent = (LevelOptionIntent) item
                .getIntent();
        //Perform what you would want to based on the values set in the intent.
        if (levelOptionIntent.getAppCode().equals(A)) {
        // Start activity A
        }elseif (levelOptionIntent.getAppCode().equals(B)) {
        // Start activity B
        }else if (levelOptionIntent.getAppCode().equals(C)) {
        // Start activity C
        }

        break;
    }
    return true;
}

The LevelOptionsIntent class is as below:

public class LevelOptionIntent extends Intent {
private int dashboardNumber;
private String appCode;
private String uniqueRecordId;
private int levelNumber;

public LevelOptionIntent() {
    super();
    // TODO Auto-generated constructor stub
}
public int getDashboardNumber() {
    return dashboardNumber;
}
public void setDashboardNumber(int dashboardNumber) {
    this.dashboardNumber = dashboardNumber;
}
public String getAppCode() {
    return appCode;
}
public void setAppCode(String appCode) {
    this.appCode = appCode;
}
public String getUniqueRecordId() {
    return uniqueRecordId;
}
public void setUniqueRecordId(String uniqueRecordId) {
    this.uniqueRecordId = uniqueRecordId;
}
public int getLevelNumber() {
    return levelNumber;
}
public void setLevelNumber(int levelNumber) {
    this.levelNumber = levelNumber;
}}

I am not sure if this is the right way of doing it though.Can someone throw some light on this.

Thanks in advance.
