[Android]點擊按鈕進入下一個Activity時顯示動畫效果

動畫效果寫在xml裡，

在按鍵的onClickListener裡如果寫成這樣

 

 @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 );        }

那麼Intent和animation是同時執行的，看不到動畫效果，

 

應該這樣寫——加入一個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 );} );
