Java开发中可以防止界面假死的刷新代码

try {

   // 创建一个线程

   thread thread = new thread() {

   public void run() {

    int i = 0 ;

    while ( true ){

    final long start = system.currenttimemillis();

    try {

     thread.sleep( 1 );

    } catch (interruptedexception e) {

     // todo auto-generated catch block

     e.printstacktrace();

    }

    final int a = i;

    if (!display.getdefault().isdisposed()) {

     runnable runnable = new runnable() {

     public void run() {

      processmodel.setprocessname(start + "---" + a);

     }

     };

     display.getdefault().syncexec(runnable);

    }

    i++;

    }

   }

   };

   thread.start();

  } catch (exception e) {

   e.printstacktrace();

  }
