Android 动画1--View控件的显示和隐藏效果

显示动画

 mShowAction = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0.0f,                       Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,                       -1.0f, Animation.RELATIVE_TO_SELF, 0.0f);               mShowAction.setDuration(500);

隐藏动画

mHiddenAction = new TranslateAnimation(Animation.RELATIVE_TO_SELF,                       0.0f, Animation.RELATIVE_TO_SELF, 0.0f,                       Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,                       -1.0f);   mHiddenAction.setDuration(500);

View的显示：

 view.startAnimation(mShowAction);    view.setVisibility(View.VISIBLE);

View的隐藏：

view.startAnimation(mHiddenAction);   view.setVisibility(View.GONE);

我们可以看下ImageView的显示：

ImageView imageView = (ImageView)findViewById(R.id.imageView1);Animation animation = AnimationUtils.loadAnimation(this, R.anim.fade_in);imageView.setBackgroundResource(R.drawable.t);imageView.startAnimation(animation);

动画效果可以用xml文件定义，定义方法网上很多的，多多参考下。
