如何从左至右一个一个地动画图像android

Question

我想从左至右一个一个地动画9个图像。我试过编码，所有的图像都在同一时间移动。我需要每个图像都应该一个接一个地移动。

ArrayList<ImageView> imageHolder; 

@TargetApi(Build.VERSION_CODES.HONEYCOMB) 
@SuppressLint("NewApi") 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    animateBottles(); 
} 

private void animateBottles() { 
    ImageView upperRowBottleOneImageView = (ImageView) findViewById(R.id.upperRowBottleOneImageView); 
    ImageView upperRowBottleTwoImageView = (ImageView) findViewById(R.id.upperRowBottleTwoImageView); 
    ImageView upperRowBottleThreeImageView = (ImageView) findViewById(R.id.upperRowBottleThreeImageView); 
    ImageView upperRowBottleFourImageView = (ImageView) findViewById(R.id.upperRowBottleFourImageView); 
    ImageView upperRowBottleFiveImageView = (ImageView) findViewById(R.id.upperRowBottleFiveImageView); 
    ImageView upperRowBottleSixImageView = (ImageView) findViewById(R.id.upperRowBottleSixImageView); 
    ImageView upperRowBottleSevenImageView = (ImageView) findViewById(R.id.upperRowBottleSevenImageView); 
    ImageView upperRowBottleEightImageView = (ImageView) findViewById(R.id.upperRowBottleEightImageView); 
    ImageView upperRowBottleNineImageView = (ImageView) findViewById(R.id.upperRowBottleNineImageView); 

    imageHolder = new ArrayList<ImageView>(); 

    imageHolder.add(upperRowBottleOneImageView); 
    imageHolder.add(upperRowBottleTwoImageView); 
    imageHolder.add(upperRowBottleThreeImageView); 
    imageHolder.add(upperRowBottleFourImageView); 
    imageHolder.add(upperRowBottleFiveImageView); 
    imageHolder.add(upperRowBottleSixImageView); 
    imageHolder.add(upperRowBottleSevenImageView); 
    imageHolder.add(upperRowBottleEightImageView); 
    imageHolder.add(upperRowBottleNineImageView); 

    for (int i = 0; i < imageHolder.size(); i++) { 
     ImageView imageView = imageHolder.get(i); 

     ObjectAnimator mover = ObjectAnimator.ofFloat(imageView, 
       "translationX", -150f, 50f); 
     mover.setDuration(4000); 

     AnimatorSet animatorSet = new AnimatorSet(); 
     animatorSet.play(mover); 
     animatorSet.start(); 
     mover.addListener(new AnimatorListener() { 

      @Override 
      public void onAnimationCancel(Animator arg0) { 
       // TODO Auto-generated method stub 

      } 

      @Override 
      public void onAnimationEnd(Animator arg0) { 
       // TODO Auto-generated method stub 

      } 

      @Override 
      public void onAnimationRepeat(Animator arg0) { 
       // TODO Auto-generated method stub 

      } 

      @Override 
      public void onAnimationStart(Animator arg0) { 
       // TODO Auto-generated method stub 

      } 

     });} 

     //try { 
      //Thread.sleep(1000); 
     //} catch (InterruptedException e) { 
     // // TODO Auto-generated catch block 
      //e.printStackTrace(); 
     //} 
    //} 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

}

为了通过一个动画图像一个你必须设置一个起始偏移延迟像每个图像：

for (int i = 0; i < imageHolder.size(); i++) { 
     ImageView imageView = imageHolder.get(i); 

     TranslateAnimation animation = new TranslateAnimation(fromX, ToX, FromY, ToY); 
     animation.setDuration(400); 
     animation.setStartOffset(100*i); 

     imageView.startAnimation(animation); 
}
