1 RelativeLayout ly=(RelativeLayout)findViewById(R.id.layout);

1 ScaleAnimation sa = new ScaleAnimation(0, 1,0,1);  //设置动画效果
2 sa.setDuration(3000);

1 LayoutAnimationController lac = new LayoutAnimationController(sa, 0.5f);   //布局动画管理器
2 lac.setOrder(LayoutAnimationController.ORDER_RANDOM);  //设置动画顺序

1 ly.setLayoutAnimation(lac);

 1 public class MainActivity extends Activity {
 2 
 3     @Override
 4     protected void onCreate(Bundle savedInstanceState) {
 5         super.onCreate(savedInstanceState);
 6         setContentView(R.layout.activity_main);
 7         
 8         RelativeLayout ly=(RelativeLayout)findViewById(R.id.layout);   //找到布局文件的id
 9         ScaleAnimation sa = new ScaleAnimation(0, 1,0,1);  //设置动画效果
10         sa.setDuration(3000);
