[Android]点击按钮进入下一个Activity时显示动画效果

动画效果写在xml里，

在按键的onClickListener里如果写成这样

?

1 2 3 4 5 6 7 8

@Override        public void onClick( View v )        {            Animation hang_fall = AnimationUtils.loadAnimation( Curriculum.this, R.anim.hang_fall );            v.startAnimation( hang_fall );            Intent i = new Intent( ThisActivity.this, NextActivity.class );            ThisActivity.this.startActivity( i );        }

那么Intent和animation是同时执行的，看不到动画效果，

应该这样写——加入一个AnimationListener

?

final ImageView ib = (ImageView)this.findViewById( R.id.photo );     ib.setOnClickListener( new OnClickListener( ) {           @Override         public void onClick( View v ) {     Animation hang_fall = AnimationUtils.loadAnimation(Curriculum.this, R.anim.hang_fall );     hang_fall.setAnimationListener(new Animation.AnimationListener()         {             public void onAnimationEnd(Animation animation)             {                 Intent i = new Intent( ThisActivity.this, NextActivity.class );                 ThisActivity.this.startActivity( i );             }               public void onAnimationRepeat(Animation animation)             {                 // Do nothing!             }               public void  onAnimationStart(Animation animation)             {                 // Do nothing!             }         });     v.startAnimation( hang_fall ); } );
