AnimationDrawable落后

Question

我使用两个空隙来制作动画，因为我需要在同一个屏幕上使用不同的动画。而这个动画适用于不同的ImageViews。当我将这两个ImageView同时添加到主屏幕时。他们开始但落后。但如果我使用相同的动画不同的ImageViews没有问题。为什么这个滞后发生我使用线程来调用。只有2个ImageView和位图非常小，只有3帧。

修改 这是一个从eclipse到android studio的导出项目。我只是在android studio中打开一个新的空项目，然后复制粘贴所有代码和资源，而不是没有任何问题。

final RelativeLayout btt = (RelativeLayout) findViewById(R.id.bottomlinear); 

 class MyThread implements Runnable {

                          public MyThread() {
                              ImageView myImage3 ;
                              myImage3 = getimage( 0,btt.getHeight(),700);
                  startAnimation(myImage3);
                              btt.addView(myImage3);
                          }

                          public void run() {
                          }
                      }
