[操作系统]Android 控件的显示隐藏上下左右移动动画


一、利用Android提供的左右移动工具类:AnimationUtils

  LinearLayout ll_first = (LinearLayout) findViewById(R.id.ll_first);  LinearLayout ll_second = (LinearLayout) findViewById(R.id.ll_second);  ll_first.setVisibility(View.GONE);  ll_second.setVisibility(View.VISIBLE);  // 向右边移出  ll_first.setAnimation(AnimationUtils.makeOutAnimation(this, true));  // 向右边移入  ll_second.setAnimation(AnimationUtils.makeInAnimation(this, true));        ll_first.setVisibility(View.VISIBLE);  ll_second.setVisibility(View.GONE);  // 向左边移入  ll_first.setAnimation(AnimationUtils.makeInAnimation(this, false));  // 向左边移出  ll_second.setAnimation(AnimationUtils.makeOutAnimation(this, false));

二、用TranslateAnimation添加动画

先写一个AnimationUtil工具类:这里仅提供上下移动效果

public class AnimationUtil {  private static final String TAG = AnimationUtil.class.getSimpleName();  /**   * 从控件所在位置移动到控件的底部   *   * @return   */  public static TranslateAnimation moveToViewBottom() {    TranslateAnimation 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);    return mHiddenAction;  }  /**   * 从控件的底部移动到控件所在位置   *   * @return   */  public static TranslateAnimation moveToViewLocation() {    TranslateAnimation mHiddenAction = 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);    mHiddenAction.setDuration(500);    return mHiddenAction;  }}

隐藏的时候设置下动画就可以了

        ll_first.setVisibility(View.GONE);        ll_second.setVisibility(View.VISIBLE);        ll_first.setAnimation(AnimationUtil.moveToViewBottom());        ll_second.setAnimation(AnimationUtil.moveToViewLocation());
