j2me 摄像头的调用

  由于工作的需要，我今天简单的测试了一下摄像头的调用程序，代码的本身很简单。但是已经可以说明问题了。

import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Form;
import javax.microedition.lcdui.Item;
import javax.microedition.lcdui.StringItem;
import javax.microedition.media.Manager;
import javax.microedition.media.Player;
import javax.microedition.media.control.VideoControl;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;

public class SheXiangTou extends MIDlet {
    Display dis;
    private Form  form;
    private StringItem si;
 public SheXiangTou() {
   dis=Display.getDisplay(this);
   form =new Form("test");
   si=new StringItem("测试摄像头","");
   form.append(si);
   dis.setCurrent(form);
 }

 protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
  // TODO Auto-generated method stub

 }

 protected void pauseApp() {
  // TODO Auto-generated method stub

 }

 protected void startApp() throws MIDletStateChangeException {
  // TODO Auto-generated method stub
  test();

 }
   private void test(){
    Player p;
     VideoControl vc;
     try{
       p = Manager.createPlayer("capture://video");
       p.realize();
       vc = (VideoControl) p.getControl("VideoControl");
       form.append(new StringItem("mmmmmmmm",""));
       if (vc != null) {
        form.append((Item)vc.initDisplayMode(VideoControl.USE_GUI_PRIMITIVE, null));//当前类继承了Form类
       }
       p.start();
     }catch(Exception e){}

   }
}
