【问题描述】：

我的 LWUIT 视频组件漂浮在我的命令之上。知道如何解决这个问题吗？我的代码如下。

public void showQuickProfileForm() 
 Form f = new Form();
        VideoComponent videoComponent = null;
        try 
            videoComponent = VideoComponent.createVideoPeer("capture://image");
         catch (IOException e) 
          //  e.printStackTrace();
            try 
                videoComponent = VideoComponent.createVideoPeer("capture://video");
             catch (IOException ex) 
              //  ex.printStackTrace();
            
        
        videoComponent.setPreferredH((int) (Display.getInstance().getDisplayHeight() * 0.8));
        videoComponent.setPreferredW(Display.getInstance().getDisplayWidth());
        Player player = (Player) videoComponent.getNativePeer();
        try 
            player.realize();
            player.start();
         catch (MediaException ex) 
            ex.printStackTrace();
        
        VideoControl videoControl = (VideoControl) player.getControl("VideoControl");
        videoComponent.start();
        f.addComponent(videoComponent);
        f.addCommand(new Command("capture", 1));
        f.show();
    

    public void actionPerformed(ActionEvent evt) 
        if (evt.getCommand().getId() == 1) 
            // midlet.destroyApp(true);
            Form d = new Form();
            d.show();
        
    

【参考方案1】：

在初始化视频控件后使用它，根据需要更改宽度和高度：

videoControl.setDisplaySize(width + 4, height - 25);
