創建一個GridFieldManager與每個焦點？

Question

我想知道GridFieldManager以及如何知道這個。

Answer 1

嘗試這一個：

public class GridScreen extends MainScreen 
{ 
GridFieldManager grid; 
public GridScreen() 
{ 
    setTitle("Grid Screen"); 
    createGUI(); 
} 
private void createGUI() 
{ 
    setTitle("GridLayoutDemo"); 
    GridFieldManager grd=new GridFieldManager(3, 3, 0); 
    grd.add(new LabelField("One",Field.FOCUSABLE)); 
    grd.add(new LabelField("Two")); 
    grd.add(new LabelField("Three",Field.FOCUSABLE)); 
    grd.add(new LabelField("Four",Field.FOCUSABLE)); 
    grd.add(new LabelField("Five",Field.FOCUSABLE)); 
    grd.add(new LabelField("Six",Field.FOCUSABLE)); 
    grd.add(new ButtonField("Seven")); 
    grd.add(new ButtonField("Eight")); 
    grd.add(new LabelField("Nine")); 
    //grd.insert(new LabelField("Insert"), 0, 2); 
    grd.delete(1, 1); 
// grd.getBackground(); 
    add(grd);  
    grd.setColumnPadding(10); 
    grd.setRowPadding(10);; 
} 
} 

這僅是一個樣本GridDemo;據此，你可以做你想做的事情; 我只給了一些不是全部的領域;當你運行這個時看到這個;
