    int proc=0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        new Thread(){
            @Override
            public void run() {
                while(proc<100){
                    proc=proc+1;
                    try {
                        sleep(1000);
                        handler.sendEmptyMessage(123);

                    } catch (InterruptedException e) {
                        // TODO 自动生成的 catch 块
                        e.printStackTrace();
                    }
                    
                }               
                
            }
            
        }.start();
    }
    
    Handler handler=new Handler(){
        @Override
        public void handleMessage(Message msg) {
            if(msg.what==123){
                progressBar1.setProgress(proc);
            }
        }
        
    };

}

 例子2

显示在标题上的进度条

需要说明的是标题的进度条是从0-10000的，而且最大值是不能设置的

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearLayout1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal"
    android:padding="10dp" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="显示" />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="隐藏" />

</LinearLayout>

MainActivity.java

                }               
                
            }
            
        };
        
        btn1.setOnClickListener(new OnClickListener() {
