RecyclerView下拉刷新和上拉加载更多
谷歌在v4包下提供了一个SwipeRefreshLayout来实现RecyclerView的下拉刷新，但是此类并不提供上拉加载更多的一个功能，网上有很多的博客实现了上拉加载，但是上拉的效果图和之前的一样，今天我就实现类似于SwipeRefreshLayout刷新的效果图。圆形进度条的实现类MaterialProgressDrawable，之后解决的就是什么时候让圆形进度条显示，如何让圆形进度条随着手指上下滑动。
就是在dispatchTouchEvent分发事件的时候，不断的去检测RecyclerView是否已经下拉到底部了，这时就让圆形进度条显示，如何再向上滑动就向上滑动，向下滑动就向下滑动，松开就计算滑动的高度是否符合加载的高度，符合就固定圆形进度条让其滚动，不符合就消失。
判断是否已经到底部了
[java]viewplaincopy
privatebooleancanPullUp(){
RecyclerView.LayoutManagerlm=mRecyclerView.getLayoutManager();
mLastVisiblePosition=getLastVisibleItemPosition();
intcount=mRecyclerView.getAdapter().getItemCount();
if(0==count){
//没有item的时候可以上拉加载
returntrue;
}elseif(mLastVisiblePosition==(count-1)){
//滑到底部了可以上拉加载
if(lm.findViewByPosition(count-1).getBottom()<=getMeasuredHeight()){
returntrue;
}
}
returnfalse;
}
不断检测滑动的位置，显示圆形进度条的位置

@Override
publicbooleandispatchTouchEvent(MotionEventevent){
if(!mIsAllowLoadMore)returnsuper.dispatchTouchEvent(event);
switch(event.getAction()){
caseMotionEvent.ACTION_DOWN:
mStartY=(int)event.getRawY();
break;
caseMotionEvent.ACTION_MOVE:
if(!mStart){
//如果不满足上拉的条件就直接分发事件
if(!canPullUp()){
returnsuper.dispatchTouchEvent(event);
}
if(canPullUp()&&!mIsCanScoll){
showRefreshArrow();
mStartY=(int)event.getRawY();
mIsCanScoll=true;
}else{
//mStartY=(int)event.getRawY();
//hideRefreshArrow();
//hide();
}
if(mVisibleCanScoll){
intendY=(int)event.getRawY();
intoffset=mStartY-endY;
//System.out.println("----------------------offset:"+offset);
LayoutParamslp=(LayoutParams)mImageView.getLayoutParams();
intbottomMargin=lp.bottomMargin;
bottomMargin+=offset;
if(bottomMargin>=PULL_IMAGE_SIZE_PX_MAX){
bottomMargin=PULL_IMAGE_SIZE_PX_MAX;
}
if(bottomMargin<=-PULL_IMAGE_SIZE_PX){
bottomMargin=-PULL_IMAGE_SIZE_PX;
}
lp.setMargins(lp.leftMargin,lp.topMargin,lp.rightMargin,bottomMargin);
mImageView.setLayoutParams(lp);
rotateAniamtor(bottomMarginROTATE_ANIM_ANGLE_PER);
mStartY=endY;
}
LayoutParamslp=(LayoutParams)mImageView.getLayoutParams();
//如果按住上拉时，上拉箭头向下滑动的时候事件不应分发
if(mVisable&&lp.bottomMargin>-PULL_IMAGE_SIZE_PX){
mIsDispatch=false;
}elseif(mVisable&&lp.bottomMargin==-PULL_IMAGE_SIZE_PX){//等到上拉箭头被隐藏掉的时候在分发事件
mIsDispatch=true;
}
//是否分发事件
if(!mIsDispatch){
returnfalse;
}
else{
returnsuper.dispatchTouchEvent(event);
}
}
break;
caseMotionEvent.ACTION_UP:
caseMotionEvent.ACTION_CANCEL:
if(!mStart){
if(mVisibleCanScoll){
LayoutParamslp=(LayoutParams)mImageView.getLayoutParams();
if(lp.bottomMargin>=PULL_IMAGE_SIZE_PX_EXECUTE){
//lp.setMargins(lp.leftMargin,lp.topMargin,lp.rightMargin,PULL_IMAGE_SIZE_PX/32);
//mImageView.setLayoutParams(lp);
//start();
getValueToTranslation();
mPrepareAnimation=true;
if(mOnPullListener!=null){
mOnPullListener.onLoadMore(this);
}
}else{
hideArrow();
}
}
if(!mStart&&!mPrepareAnimation)
hideArrow();
}
mIsCanScoll=false;
break;
}
returnsuper.dispatchTouchEvent(event);
}
当上拉松开时会有一个滑动的动画

mAnimator.setRepeatMode(ValueAnimator.INFINITE);
