Android動畫快速結束

Question

我遇到以下問題：我在我的android應用程序中有一個動畫，它在屏幕上移動了UI元素，即它是一個翻譯動畫，它通常工作正常。讓我們說，它正在從位置（0,0）移動到（0，200）在屏幕上。問題是，有時這種情況發生得非常快（如0.001秒），一旦程序加載，我就看不到物體的移動，但是我發現它處於最終位置（0,200）。這裏是我的代碼：

Handler handler = new Handler(); 

float height; 
private RelativeLayout relativeLayoutDoughnutAndLogoTogether; 
private RelativeLayout logo_donut_together2; 
private ImageView imgSplash, image2; 
private DoughnutView doughnutView; 

    protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    relativeLayoutDoughnutAndLogoTogether = (RelativeLayout) findViewById(R.id.logo_donut_together); 
    logo_donut_together2 = (RelativeLayout) findViewById(R.id.logo_donut_together2); 
    imgSplash = (ImageView) findViewById(R.id.turkcell_logo); 
    image2 = (ImageView) findViewById(R.id.ImageView02); 

    int logoHeight = imgSplash.getDrawable().getIntrinsicHeight(); 
    int screenHeight = getWindowManager().getDefaultDisplay().getHeight(); 
    final int centerScreen = (screenHeight-logoHeight)/2; 

    doughnutView = new DoughnutView(this) { 
     @Override 
     public void onAnimationComplete() { 
       float density = getResources().getDisplayMetrics().density; 
       Animation moveToTop = new TranslateAnimation(0, 0, centerScreen-50*density, 0); 
       moveToTop.setDuration(1000);       
       relativeLayoutDoughnutAndLogoTogether.startAnimation(moveToTop);      

       logo_donut_together2.setVisibility(View.GONE); 
       logo_donut_together2.removeView(doughnutView); 
       relativeLayoutDoughnutAndLogoTogether.addView(doughnutView);        
       relativeLayoutDoughnutAndLogoTogether.setVisibility(0); 
     } 
    }; 


    doughnutView.setStartAngle(0); 
    doughnutView.setColorFront(Color.rgb(232, 232, 232)); 
    doughnutView.setSweepAngle(360); 
    doughnutView.setStrokeWidth(4); 
    doughnutView.setMarginAll(10); 
    doughnutView.setColorBack(Color.rgb(63, 176, 232)); 
    doughnutView.startAnimation(0); 
    logo_donut_together2.addView(doughnutView); 

} 

我實際上是在談論onAnimationComplete部分的代碼。如果有人能幫忙，我將不勝感激。

感謝

你必須寫上onAnimatinEnd（動畫動畫）的邏輯{...} 這或許可以幫助你......

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

      } 

      @Override 
      public void onAnimationEnd(Animation animation) { 
      logo_donut_together2.setVisibility(View.GONE); 
      logo_donut_together2.removeView(doughnutView); 
      relativeLayoutDoughnutAndLogoTogether.addView(doughnutView);        
      relativeLayoutDoughnutAndLogoTogether.setVisibility(0); 

      } 

      @Override 
      public void onAnimationRepeat(Animation animation) { 

      } 
     });
