请注意：你不能在资源文件夹中存储你只能存储在SD卡

Note: you can not store in resource folder you can only store in SDcard

 class screen extends MainScreen implements FieldChangeListener
    {
        private VideoControl vc;
        private String encoding;
        private Player p;
        private Field viewFinder;
        private BitmapField bitmapField;
        private ButtonField btn;
        public screen() {
            btn=new ButtonField("snap",Field.FOCUSABLE);
            btn.setChangeListener(this);
            add(btn);
        }
        public void fieldChanged(Field field, int context) {
            if(field==btn)
            {
                try{                        
                    p = Manager.createPlayer("capture://video");                        
                    p.realize();
                    p.prefetch();
                    p.start();
                    vc = (VideoControl) p.getControl("VideoControl");
                    viewFinder = (Field)vc.initDisplayMode(VideoControl.USE_GUI_PRIMITIVE, "net.rim.device.api.ui.Field");
                    vc.setVisible(true);    
                    final String imageType = "encoding=jpeg&width=640&height=480&quality=superfine";

                    UiApplication.getUiApplication().invokeLater(new Runnable(){
                        public void run(){

byte[] image = vc.getSnapshot(imageType);
                        FileConnection conn = (FileConnection)Connector.open("file:///store/home/user/pictures/"+System.currentTimeMillis()+".jpeg", Connector.READ_WRITE);
                        conn.create();
                        OutputStream out = conn.openOutputStream();
                        out.write(image);
                        out.flush();
                        out.close();
                        conn.close();  
                                Bitmap image1 = Bitmap.createBitmapFromBytes(imageBytes, 0, imageBytes.length, 4);
                                bitmapField.setBitmap(image1);
                                add(bitmapField);                           


                        }
                    });

                } catch (Exception me){

                }
            }
