需要關於MainScreen中繪畫方法的幫助信息。使用上面的代碼,我試圖呈現一些列表。它工作正常。但它隱藏了我使用setStatus()方法添加的所有狀態欄圖標。當我刪除繪畫方法時,狀態欄中的按鈕顯示出來。我也嘗試過使用setRe g.pushRegion(),但沒有運氣。狀態按鈕在BlackBerry中被覆蓋繪畫方法隱藏
下面是示例代碼:
private void addStatusBar(){
manager = new HorizontalFieldManager();
manager.add(new BitmapField(ImageUtility.loadBitMap("ask.jpg")));
manager.add(new BitmapField(ImageUtility.loadBitMap("experts.jpg")));
manager.add(new BitmapField(ImageUtility.loadBitMap("search.jpg")));
manager.add(new BitmapField(ImageUtility.loadBitMap("my_profile.jpg")));
manager.add(new BitmapField(ImageUtility.loadBitMap("groups.jpg")));
manager.add(new BitmapField(ImageUtility.loadBitMap("analitics.jpg")));
setStatus(manager);
}
protected void paint(Graphics graphics) {
//graphics.pushRegion(new XYRect(0, 0, getPreferredWidth(), getPreferredHeight()));
Bitmap image = ImageUtility.loadBitMap("header2.jpg");
graphics.drawBitmap(0, 0, 500, image.getHeight(), image, 0, 0);
for(int i =0; i < 5; i++){
fieldList.drawListRow(fieldList, graphics, i, 50 + (i*50), 20);
}
}
