如何使用Eclipse在Blackberry屏幕中间显示进程条？

Answer 1

使用这个：

HorizontalFieldManager hfm = new HorizontalFieldManager(USE_ALL_HEIGHT);
VerticalFieldManager vfm = new VerticalFieldManager(USE_ALL_WIDTH | FIELD_VCENTER);
ProgressBarField pbf = new ProgressBarField(0, 100, 50, USE_ALL_WIDTH);
vfm.add(pbf);
hfm.add(vfm);
add(hfm);
