Android Create a simple menu programmatically

A--C's method works, but you should avoid setting the click listeners manually. Especially when you have multiple menu items.

I prefer this way:

private static final int MENU_ITEM_ITEM1 = 1;...@Overridepublic boolean onCreateOptionsMenu(Menu menu) {    menu.add(Menu.NONE, MENU_ITEM_ITEM1, Menu.NONE, "Item name");    return true;}@Overridepublic boolean onOptionsItemSelected(MenuItem item) {    switch (item.getItemId()) {    case MENU_ITEM_ITEM1:        clearArray();        return true;    default:        return false;  }}

By using this approach you avoid creating unecessary objects (listeners) and I also find this code easier to read and understand.

Something like this might work:

public boolean onCreateOptionsMenu(Menu menu) {  MenuItem item = menu.add ("Clear Array");  item.setOnMenuItemClickListener (new OnMenuItemClickListener(){    @Override    public boolean onMenuItemClick (MenuItem item){      clearArray();      return true;    }  });  return true;}

Menu gives us a handy method, add(), which allows you to add a MenuItem. So we make one. Then we assign an OnMenuItemClickListener to the MenuItem and override its onMenuItemClick() to do what we want it to do.

Programmatically, I was able to create a simple menu using the following code.

private final int MenuItem_EditId = 1, MenuItem_DeleteId = 0;@Override  public boolean onCreateOptionsMenu(Menu menu){    MenuItem edit_item = menu.add(0, MenuItem_EditId, 0, R.string.edit);    edit_item.setIcon(R.drawable.edit);    edit_item.setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_IF_ROOM);    MenuItem delete_item = menu.add(0, MenuItem_DeleteId, 1, R.string.edit);    delete_item.setIcon(R.drawable.delete);    delete_item.setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_IF_ROOM);    return super.onCreateOptionsMenu(menu);}
