onclick android的按钮聆听者

Question

在我的android应用程序中，我改变按钮图像1秒。有一组按钮。在任何一个按钮的1秒图像被改变。如果在1秒我点击那个特定的按钮我想执行一些operation.using的onclick监听我tried.but它不是我working.How能做到这一点？请帮我 下面是代码 -

protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.next); 

    // **here i want to call method for onclick of button.** 
//  buttonclick(); 
    myTimer = new Timer(); 

    myTimer.schedule(new TimerTask() { 

    @Override 
    public void run() { 
     if(time==-1){ 

     onStop(); 
     } 
     else 
     runOnUiThread(new Runnable() { 
     public void run() { 

      Random rand=new Random();    
      time=time-1; 
      but1=(Button) findViewById(R.id.b1); 
      but1.setBackgroundResource(R.drawable.happy); 
      but1.setContentDescription("happy"); 
      but2=(Button) findViewById(R.id.b2); 
      but2.setBackgroundResource(R.drawable.happy); 
      but2.setContentDescription("happy"); 

      int num = rand.nextInt(buttonIds.length); 
      int buttonId = buttonIds[num]; 

      Button bb=(Button) findViewById(buttonId); 

      if(bb.getContentDescription().equals(button.getContentDescription())) 
      { 
      bb.setBackgroundResource(R.drawable.happy); 
      bb.setContentDescription("happy"); 
      wrong++; 
      } 
      else 
      { 
      bb.setBackgroundResource(R.drawable.whoa); 
      count++; 

      bb.setContentDescription("whoa"); 
      } 

     } 
     }); 
    } 

    },0, 1000); 
} 

    public void onClick(View v){ 
//when i clicked on any button its not even entering here 
    System.out.println("in onlcik............"); 
    int aaa=v.getId(); 
    System.out.println("click id is------------"+aaa); 
    for(i=0;i<9;i++){ 
    if(aaa==buttonIds[i]){ 
     findViewById(buttonIds[i]).setOnClickListener(new View.OnClickListener() { 

      Drawable dd=findViewById(buttonIds[i]).getBackground(); 
      public void onClick(View arg0) { 
      System.out.println("yes..."); 

      } 
     }); 
    } 
    } 
} 

} 

我更新了代码 - 我用onclicklistener.but它也不工作。

假设你已经正确设置onClick处理您的按钮，你可以调用它简单地调用button.performClick()
