试试这个 -

GridFieldManager grid = new GridFieldManager(2,2,0); 
EncodedImage g1 = EncodedImage.getEncodedImageResource("image1.png");
EncodedImage g2 = EncodedImage.getEncodedImageResource("image2.png");
EncodedImage g3 = EncodedImage.getEncodedImageResource("image3.png");
EncodedImage g4 = EncodedImage.getEncodedImageResource("image4.png");

grid.add(new BitmapField(g1.getBitmap(),FOCUSABLE){
          protected boolean navigationClick(int status, int time){
                          //here your can add your code.
                return true;
            }

    });
grid.add(new BitmapField(g2.getBitmap(),FOCUSABLE){
              protected boolean navigationClick(int status, int time){
                              //here your can add your code.
                    return true;
                }

        });
grid.add(new BitmapField(g3.getBitmap(),FOCUSABLE){
              protected boolean navigationClick(int status, int time){
                              //here your can add your code.
                    return true;
                }

        });
grid.add(new BitmapField(g4.getBitmap(),FOCUSABLE){
              protected boolean navigationClick(int status, int time){
                              //here your can add your code.
                    return true;
                }

        });



 add(grid );
