在android如何執行一個接一個的任務

當程序打開時它會顯示一個動畫，然後它會顯示餅圖結果。

我的代碼是：---

public class Popup_animation11 extends Activity { 

    private static int[] COLORS = new int[] { Color.MAGENTA, Color.CYAN }; 
    LinearLayout layout; 

    private CategorySeries mSeries = new CategorySeries(""); 
    private DefaultRenderer mRenderer = new DefaultRenderer(); 
    private GraphicalView mChartView; 
     Context ctx; 

    private TransparentProgressDialog pd; 
    private Handler h; 
    private Runnable r; 

    EditText name1,name2; 

    private int[] VALUES = { 40, 60 }; 
    String x1,y1; 
    Button btnOpenPopup; 
    String[] NAME_LIST ; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.popup_main); 

     Button btnOpenPopup = (Button)findViewById(R.id.openpopup); 
     btnOpenPopup.setOnClickListener(new Button.OnClickListener(){ 

      @Override 
      public void onClick(View arg0) { 

       pd.show(); 
      } 
     }); 


     h = new Handler(); 
      pd = new TransparentProgressDialog(this, R.drawable.uktrafficlights); 
      r =new Runnable() { 
       @Override 
       public void run() { 
        if (pd.isShowing()) { 
         pd.dismiss(); 
        } 
       } 
      }; 



    } 



    @Override 
    protected void onDestroy() { 
     h.removeCallbacks(r); 
     if (pd.isShowing()) { 
      pd.dismiss(); 
     } 
     super.onDestroy(); 
    } 

    private class TransparentProgressDialog extends Dialog { 

     private ImageView iv; 

     public TransparentProgressDialog(Context context, int resourceIdOfImage) { 
      super(context, R.style.TransparentProgressDialog); 
      WindowManager.LayoutParams wlmp = getWindow().getAttributes(); 
      wlmp.gravity = Gravity.CENTER_HORIZONTAL; 
      getWindow().setAttributes(wlmp); 
      setTitle(null); 
      setCancelable(false); 
      setOnCancelListener(null); 
      LinearLayout layout = new LinearLayout(context); 
      layout.setOrientation(LinearLayout.VERTICAL); 
      LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); 
      iv = new ImageView(context); 
      iv.setImageResource(resourceIdOfImage); 
      layout.addView(iv, params); 
      addContentView(layout, params); 
     } 

     @Override 
     public void show() { 
      super.show(); 
      RotateAnimation anim = new RotateAnimation(0.0f, 360.0f , Animation.RELATIVE_TO_SELF, .5f, Animation.RELATIVE_TO_SELF, .5f); 

      anim.setInterpolator(new LinearInterpolator()); 
      anim.setRepeatCount(Animation.INFINITE); 
      anim.setDuration(3000); 
      iv.setAnimation(anim); 
      iv.startAnimation(anim); 

      anim.setAnimationListener(new Animation.AnimationListener() { 
       @Override 
       public void onAnimationStart(Animation animation) { 



       } 

       @Override 
       public void onAnimationEnd(Animation animation) { 
        //here display data 


        mRenderer.setApplyBackgroundColor(true); 
        mRenderer.setBackgroundColor(Color.argb(100, 50, 50, 50)); 
        mRenderer.setChartTitleTextSize(20); 
        mRenderer.setLabelsTextSize(15); 
        mRenderer.setLegendTextSize(15); 
        mRenderer.setMargins(new int[] { 20, 30, 15, 0 }); 
        mRenderer.setZoomButtonsVisible(true); 
        mRenderer.setStartAngle(90); 
        mChartView = ChartFactory.getPieChartView(ctx, mSeries, mRenderer); 

       LayoutInflater layoutInflater = (LayoutInflater)getBaseContext() .getSystemService(LAYOUT_INFLATER_SERVICE); 


        View popupView = layoutInflater.inflate(R.layout.main_piechart, null); 
          final PopupWindow popupWindow = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT); 
          layout = (LinearLayout)popupView.findViewById(R.id.chart); 
          layout.addView(mChartView); 

          name1=(EditText) findViewById(R.id.ext1); 
          name2=(EditText) findViewById(R.id.ext2); 
          x1=name1.getText().toString(); 
          y1=name2.getText().toString(); 
          NAME_LIST = new String[] { x1 , y1 }; 
          for (int i = 0; i < VALUES.length; i++) { 

           mSeries.add(NAME_LIST[i] + "(" + VALUES[i]+"%)", VALUES[i]); 
           SimpleSeriesRenderer renderer = new SimpleSeriesRenderer(); 
           renderer.setColor(COLORS[(mSeries.getItemCount() - 1) % COLORS.length]); 
           mRenderer.addSeriesRenderer(renderer); 
           } 

           if (mChartView != null) { 

           mChartView.repaint(); 

           } 


          Button btnDismiss = (Button)popupView.findViewById(R.id.dismiss); 
          btnDismiss.setOnClickListener(new Button.OnClickListener(){ 

        @Override 
        public void onClick(View v) { 

        popupWindow.dismiss(); 
        }}); 

          popupWindow.showAsDropDown(btnOpenPopup, 50, -30); 

       } 

       @Override 
       public void onAnimationRepeat(Animation animation) { 
        // TODO Auto-generated method stub 


       } 


    }); 
    } 
    } 
}

但問題是，當我打開程序，動畫正在運行，running.the結果不來了。我的要求是第一次動畫，然後結果..但只有動畫正在運行..在我的代碼中的問題在哪裏？在此先感謝

我編輯的代碼是：---
