多個android動畫不能同時運行

Question

我有picView.startAnimation(anim);和picView.startAnimation(anim2);，但只有picView.startAnimation(anim2);有效。

當我刪除第二個動畫只有picView.startAnimation(anim);作品。

我希望兩個動畫都能同時運行，我做錯了什麼？

的代碼我有

public class PicView extends Activity { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.pic_view); 

     LinearLayout myLL = (LinearLayout) findViewById(R.id.LinearLayout2); 

     final ImageView picView = new ImageView(this); 
     myLL.addView(picView); 

     final TextView tv = new TextView(this); 
     myLL.addView(tv); 


     Animation anim = AnimationUtils.loadAnimation(PicView.this, R.anim.anim_button); 
     Animation anim2 = AnimationUtils.loadAnimation(PicView.this, R.anim.anim_button2); 
     picView.setImageResource(R.drawable.a0000); 
     picView.startAnimation(anim); 
     picView.startAnimation(anim2); 

    } 
}

你必須創建一個AnimationSet。

事情是這樣的：

Animation anim = AnimationUtils.loadAnimation(PicView.this, R.anim.anim_button); 
Animation anim2 = AnimationUtils.loadAnimation(PicView.this, R.anim.anim_button2); 

AnimationSet as = new AnimationSet(true); 
as.addAnimation(anim); 
as.addAnimation(anim2); 

viewYouWantToAnimate.setAnimation(as); 

as.start();
