@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
