Dialog

BaseBottomDialogFragment

底部弹出DialogFragment,宽度match parent,高度wrap content,有进入动画和退出动画。

advancedrecyclerview介绍

advancedrecyclerview侧滑封装

advancedrecyclerview提供了很多强大的功能，但是相对的使用成本还是有点大，因为项目侧滑的样式基本都一样，故基于项目，封装了一下~~

/** * Created by rc on 2017/8/31. * Description: 基于advanceRecyclerView侧滑的封装 */public abstract class BaseSwipeAdapter<T, V extends WrapAbstractSwipeableItemViewHolder>        extends RecyclerView.Adapter<V> implements SwipeableItemAdapter<V> {    protected List<T> mList;    private interface Swipeable extends SwipeableItemConstants {    }    public BaseSwipeAdapter(List<T> list) {        mList = list;        // requires stable ID, and also        // have to implement the getItemId() method appropriately        setHasStableIds(true);    }    @Override    public long getItemId(int position) {        return getContentItemId(position);    }    /**     * @return 返回不同的Id     */    protected abstract long getContentItemId(int position);    @Override    public V onCreateViewHolder(ViewGroup parent, int viewType) {        View view = LayoutInflater.from(parent.getContext()).inflate(getHolderLayoutId(), parent, false);        return getViewHolder(view);    }    protected abstract V getViewHolder(View view);    protected abstract    @LayoutRes    int getHolderLayoutId();    @Override    public void onBindViewHolder(V holder, int position) {        onBindContentViewHolder(holder, position, mList.get(position));    }    protected abstract void onBindContentViewHolder(V holder, int position, T t);    @Override    public int getItemCount() {        return mList == null ? 0 : mList.size();    }    /**     * @param holder   holder     * @param position 当前的位置     * @param x        touch x 位置     * @param y        touch y 位置     * @return 滑动的方向     */    @Override    public int onGetSwipeReactionType(V holder, int position, int x, int y) {        if (ViewUtils.hitTest(holder.getSwipeableContainerView(), x, y)) {            return Swipeable.REACTION_CAN_SWIPE_BOTH_H;        } else {            return Swipeable.REACTION_CAN_NOT_SWIPE_BOTH_H;        }    }    /**     * 该方法用于在滑动的时候，动态设置背景是否可见     *     * @param holder   holder     * @param position 当前位置     * @param type     当前滑动的类型     */    @Override    public void onSetSwipeBackground(V holder, int position, int type) {        if (type == Swipeable.DRAWABLE_SWIPE_NEUTRAL_BACKGROUND) {            holder.getBeBindView().setVisibility(View.GONE);        } else {            holder.getBeBindView().setVisibility(View.VISIBLE);        }    }    /**     * 松手后进行回调     *     * @param holder   viewholder     * @param position 点击item的position     * @param result   松手收的状态，打开 or 闭合     * @return 对应的处理事件     */    @Override    public SwipeResultAction onSwipeItem(V holder, int position, int result) {        switch (result) {            case Swipeable.RESULT_SWIPED_LEFT:                //向左边滑动                return new SwipeLeftResultAction(this, position);            case Swipeable.RESULT_SWIPED_RIGHT://向右滑动            case Swipeable.RESULT_CANCELED://取消            default:                if (position != RecyclerView.NO_POSITION) {                    return new UnpinResultAction(this, position);                } else {                    return null;                }        }    }    private class SwipeLeftResultAction extends SwipeResultActionMoveToSwipedDirection {        private BaseSwipeAdapter mAdapter;        private int position;        public SwipeLeftResultAction(BaseSwipeAdapter adapter, int position) {            mAdapter = adapter;            this.position = position;        }        @Override        protected void onPerformAction() {            super.onPerformAction();            //刷新数据，标志打开            onSwipeLeftAction(mAdapter, position, mList.get(position));        }        @Override        protected void onCleanUp() {            super.onCleanUp();            mAdapter = null;        }    }    private class UnpinResultAction extends SwipeResultActionDefault {        private BaseSwipeAdapter mAdapter;        private int position;        public UnpinResultAction(BaseSwipeAdapter adapter, int position) {            this.mAdapter = adapter;            this.position = position;        }        @Override        protected void onPerformAction() {            super.onPerformAction();            //刷新数据，标志关闭            onUnPinAction(mAdapter, position, mList.get(position));        }        @Override        protected void onCleanUp() {            super.onCleanUp();            mAdapter = null;        }    }    protected abstract void onUnPinAction(BaseSwipeAdapter adapter, int position, T t);    protected abstract void onSwipeLeftAction(BaseSwipeAdapter adapter, int position, T t);    public void addItems(List<T> list) {        mList.clear();        mList.addAll(list);        notifyItemRangeInserted(0, mList.size());    }}

/** * Created by rc on 2017/9/1. * Description: */public abstract class WrapAbstractSwipeableItemViewHolder extends AbstractSwipeableItemViewHolder {    public WrapAbstractSwipeableItemViewHolder(View itemView) {        super(itemView);    }    public abstract View getBeBindView();}

public class ViewUtils {    public static boolean hitTest(View v, int x, int y) {        final int tx = (int) (ViewCompat.getTranslationX(v) + 0.5f);        final int ty = (int) (ViewCompat.getTranslationY(v) + 0.5f);        final int left = v.getLeft() + tx;        final int right = v.getRight() + tx;        final int top = v.getTop() + ty;        final int bottom = v.getBottom() + ty;        return (x >= left) && (x <= right) && (y >= top) && (y <= bottom);    }}

自定义控件相关

1. 在处理控件移动时距离的限制

  /**     * @param top     * @param dy       手指移动偏移量 上拉为正，下拉为负     * @param minValue 允许移动到的最小值     * @param maxValue 允许移动到的最大值     * @return     */    public int getAreaValue(int top, int dy, int minValue, int maxValue) {        //不允许继续往上拉        if (top + dy < minValue) {            return minValue - top;        }        //不允许继续往下拉        if (top + dy > maxValue) {            return maxValue - top;        }        //返回正常的偏移量        return dy;    }

2.根据触摸事件，返回是否点击当前view

   /**     * 根据触摸事件，返回是否点击当前view     *      *     * @param view 需要判断的view     * @param event 触摸事件     * @return true 点击     */    public boolean isClickView(View view, MotionEvent event) {        Rect rect = new Rect();        view.getHitRect(rect);        return rect.contains(((int) event.getX()), ((int) event.getY()) + getScrollY());    }
