UI线程与其他线程之间使用处理程序进行通信(Communication between UI thread and other threads using handler)

 如何在UI线程和后台线程之间进行线程间通信？ 我想在这里使用通用处理程序概念来更新我的UI。 我有如下概念 
 
new Thread(new Runnable() {
         public void run() {
             while (mProgressStatus < 100) {
                 mProgressStatus = doWork();

                 // Update the progress bar
                 mHandler.post(new Runnable() {
                     public void run() {
                         mProgress.setProgress(mProgressStatus);
                     }
                 });
             }
         }
     }).start();
 
 我想使用两个类，一个类包含主线程，另一个类包含后台线程，它们使用相同的处理程序。 我该如何实现？ 我知道这很常见，但我发现很难完全实现。 

How to do inter thread communication between UI thread and background thread? I want use common handler concept here to update my UI. I have the concept as below
 
new Thread(new Runnable() {
         public void run() {
             while (mProgressStatus < 100) {
                 mProgressStatus = doWork();

                 // Update the progress bar
                 mHandler.post(new Runnable() {
                     public void run() {
                         mProgress.setProgress(mProgressStatus);
                     }
                 });
             }
         }
     }).start();
 
I want to use two classes, one class contains main thread, another class contains background thread and they use the same handler. How do I implement this? I know it is very common but I am finding it difficult to exactly implement.
