NestedScrollView嵌套RecycleView滑动冲突解决办法解决办法：1.简单的⽅法⾸先把design库和V7库升级到23.2以上，然后添加如下代码othScrollbarEnabled(true);oMeasureEnabled(true);outManager(linearLayoutManager);FixedSize(true);tedScrollingEnabled(false);经验证好⽤。。。2.⽐较⿇烦的，重写LinearLayoutManager和NestedScrollViewpublic class CustomLinearLayoutManager extends LinearLayoutManager {

public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {

super(context, orientation, reverseLayout);

}

private int[] mMeasuredDimension = new int[2];

@Override

public void onMeasure(er recycler, state,

int widthSpec, int heightSpec) {

final int widthMode = e(widthSpec);

final int heightMode = e(heightSpec);

final int widthSize = e(widthSpec);

final int heightSize = e(heightSpec);

int width = 0;

int height = 0;

for (int i = 0; i < getItemCount(); i++) {

if (getOrientation() == HORIZONTAL) {

measureScrapChild(recycler, i,

asureSpec(i, IFIED),

heightSpec,

mMeasuredDimension);

width = width + mMeasuredDimension[0];

if (i == 0) {

height = mMeasuredDimension[1];

}

} else {

measureScrapChild(recycler, i,

widthSpec,

asureSpec(i, IFIED),

mMeasuredDimension);

height = height + mMeasuredDimension[1];

if (i == 0) {

width = mMeasuredDimension[0];

}

}

}

switch (widthMode) {

case Y:

width = widthSize;

case _MOST:

case IFIED:

} }

switch (heightMode) {

case Y:

height = heightSize;

case _MOST:

case IFIED:

}

setMeasuredDimension(width, height);

}

ewToPosition(view, position);
