先上图:

我们得自己定义ProgressBar的样式

     
     	
      
       	//定义的是背景色		
       			
        			
        		
       	
      	
      
          //假设有2级进度，须要定义这一项,gradient定义的是渐变色，clip假设没有的话，进度条会充满整个Progessbar		
       			
        				
         				
         			
        		
       	
      	
      
         //这个是定义1级进度，假设1级进度比2级进度大且1级进度不透明。就能够覆盖掉2级进度		
       			
        				
         				
         			
        		
       	
      
     

在代码里这样使用：

private ProgressBar mProgressBar;	private Task mTask = new Task();	private int mCount = 0;	private Handler mHander = new MyHandler();		@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		requestWindowFeature(Window.FEATURE_NO_TITLE);		setContentView(R.layout.activity_main);		mProgressBar = (ProgressBar)findViewById(R.id.progress);		Timer timer = new Timer();		timer.schedule(mTask, 1000, 1000);	}		private class MyHandler extends Handler{		@Override		public void handleMessage(Message msg) {			mCount += 10;			mProgressBar.setProgress(mCount);			super.handleMessage(msg);		}	}		private class Task extends TimerTask{		@Override		public void run() {			mHander.sendEmptyMessage(10);		}	}

对于圆形并有转圈动画的进度条:shape的值(rectagle矩形，oval椭圆，line水平直线。ring环形) tpye的值:渐变的样式 liner线性渐变 radial环形渐变 sweep
