推荐答案

添加一个侦听您的第一个动画，并在方法： onAnimationEnd（），然后启动你的第二个第二图像的动画，等
例如：

add a listener your first animation , and in the method : onAnimationEnd() , then launch your second animation of the second image , and so on Example :

注意：您的初始化和IMG2知名度IMG3为 GONE

NOTE : initialise your img2 and img3 visibility to GONE

public class YourActivity extends Activity implements AnimationListener{
......
@Override 
public void onCreate( Bundle savedInstanceState){
super.onCreate(savedInstanceState);
....

ScaleAnimation a1 , a2 , a3;
//define your animations 
a1 = new ScaleAnimation(0.0f,1.0f);
a2 = new ScaleAnimation(0.0f,1.0f);
a3 = new ScaleAnimation(0.0f,1.0f);

// duration and behavior of ur animations
a1.setFillAfter(true);
a1.setDuration(1000);
a2.setFillAfter(true);
a2.setDuration(1000);
a3.setFillAfter(true);
a3.setDuration(1000);

a1.setAnimationListener(this);
a2.setAnimationListener(this);
a3.setAnimationListener(this);

img1.startAnimation(a1);
}

Override
public void onAnimationEnd(Animation a){
if(a == a1 ){ 
   img2.setVisibility(View.VISIBLE);
   img2.startAnimation(a2);
}

if(a == a2){
   img3.setVisibility(View.VISIBLE);
   img3.startAnimation(a3);
}

if(a == a3){
   startActivity(new Intent(YourActivity.this , SecondActivity.class);
}
}
}
