android-recyclerview-listener

实现了列表的上滑手势上浮隐藏，类似Toolbar效果，主要参考了http://www.jcodecraeer.com/a/anzhuokaifa/androidkaifa/2015/0317/2612.html

最终效果

使用

设置HidingScrollListener监听

// 上下滚动隐藏和显示
mRecyclerView.addOnScrollListener(new HidingScrollListener() {
    @Override
    public void onHide() {
        hideViews();// 你自己的隐藏动画
    }

    @Override
    public void onShow() {
        showViews();// 你自己的显示动画
    }
});

我是怎么做的

/**
  *下拉刷新恢复
  */
private void showViews() {
  // 计算下移最大高度
  int height = my_profit.getHeight() + tabs.getHeight();
  // 恢复原来位置
  my_profit.animate().translationY(0).setInterpolator(new AccelerateDecelerateInterpolator()).start();
  // tab栏恢复原来位置
  tabs.animate().translationY(0).setInterpolator(new AccelerateDecelerateInterpolator()).start();
  // 列表刷新view下移最大高度
  swiperefresh.animate().translationY(+height).setInterpolator(new AccelerateDecelerateInterpolator()).start();
  // 无数据view下移最大高度
  view_no_data.animate().translationY(+height).setInterpolator(new AccelerateDecelerateInterpolator()).start();

  // 记住该布局整体高度
  if (maxHeight == 0 ){
      maxHeight = mainView.getHeight();
  }
  // 动态变化列表刷新view高度
  ValueAnimator valueAnimator1 = ValueAnimator.ofInt(swiperefresh.getHeight(), maxHeight - height);
  valueAnimator1.setInterpolator(new AccelerateDecelerateInterpolator());
  valueAnimator1.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
      @Override
      public void onAnimationUpdate(ValueAnimator valueAnimator) {
          Integer value = (Integer) valueAnimator.getAnimatedValue();
          swiperefresh.getLayoutParams().height = value.intValue();
          swiperefresh.requestLayout();
      }
  });
  // 动态变化列表view高度
  ValueAnimator valueAnimator2 = ValueAnimator.ofInt(view_no_data.getHeight(), maxHeight - height);
  valueAnimator2.setInterpolator(new AccelerateDecelerateInterpolator());
  valueAnimator2.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
      @Override
      public void onAnimationUpdate(ValueAnimator valueAnimator) {
          Integer value = (Integer) valueAnimator.getAnimatedValue();
          view_no_data.getLayoutParams().height = value.intValue();
          view_no_data.requestLayout();
      }
  });

  AnimatorSet animatorSet = new AnimatorSet();
  animatorSet.playTogether(valueAnimator1, valueAnimator2);
  animatorSet.start();
}

/**
  *上浮隐藏
  */
private void hideViews() {
  int height = my_profit.getHeight();
  my_profit.animate().translationY(-height).setInterpolator(new AccelerateDecelerateInterpolator()).start();
  tabs.animate().translationY(-height).setInterpolator(new AccelerateDecelerateInterpolator()).start();
  swiperefresh.animate().translationY(+tabs.getHeight()).setInterpolator(new AccelerateDecelerateInterpolator()).start();
  view_no_data.animate().translationY(+tabs.getHeight()).setInterpolator(new AccelerateDecelerateInterpolator()).start();

  if (maxHeight == 0){
      maxHeight = mainView.getHeight();
  }
  ValueAnimator valueAnimator1 = ValueAnimator.ofInt(swiperefresh.getHeight(), maxHeight - tabs.getHeight());
  valueAnimator1.setInterpolator(new AccelerateDecelerateInterpolator());
  valueAnimator1.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
      @Override
      public void onAnimationUpdate(ValueAnimator valueAnimator) {
          Integer value = (Integer) valueAnimator.getAnimatedValue();
          swiperefresh.getLayoutParams().height = value.intValue();
          swiperefresh.requestLayout();
      }
  });

  ValueAnimator valueAnimator2 = ValueAnimator.ofInt(view_no_data.getHeight(), maxHeight - tabs.getHeight());
  valueAnimator2.setInterpolator(new AccelerateDecelerateInterpolator());
  valueAnimator2.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
      @Override
      public void onAnimationUpdate(ValueAnimator valueAnimator) {
          Integer value = (Integer) valueAnimator.getAnimatedValue();
          view_no_data.getLayoutParams().height = value.intValue();
          view_no_data.requestLayout();
      }
  });

  AnimatorSet animatorSet = new AnimatorSet();
  animatorSet.playTogether(valueAnimator1, valueAnimator2);
  animatorSet.start();
}

我的布局

根布局是一个FrameLayout，然后利用上下移动的动画来实现上浮隐藏。
