但对于交错 GridLayoutManager。 我试图从这个很好的答案中编辑代码：
public class StaggeredGridAutofitLayoutManager extends StaggeredGridLayoutManager {
private int mColumnWidth;
private boolean mColumnWidthChanged = true;
public StaggeredGridAutofitLayoutManager(Context context, int columnWidth, int orientation) {
/* Initially set spanCount to 1, will be changed automatically later. */
super(1, orientation);
setColumnWidth(checkedColumnWidth(context, columnWidth));
}
private int checkedColumnWidth(Context context, int columnWidth) {
if (columnWidth <= 0) {
/* Set default columnWidth value (48dp here). It is better to move this constant
to static constant on top, but we need context to convert it to dp, so can't really
do so. */
columnWidth = (int) TypedValue.applyDimension(PLEX_UNIT_DIP, 48,
context.getResources().getDisplayMetrics());
}
return columnWidth;
}
public void setColumnWidth(int newColumnWidth) {
if (newColumnWidth > 0 && newColumnWidth != mColumnWidth) {
mColumnWidth = newColumnWidth;
mColumnWidthChanged = true;
}
}
@Override
public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
if (mColumnWidthChanged && mColumnWidth > 0) {
int totalSpace;
if (getOrientation() == VERTICAL) {
totalSpace = getWidth() - getPaddingRight() - getPaddingLeft();
} else {
totalSpace = getHeight() - getPaddingTop() - getPaddingBottom();
}
int spanCount = Math.max(1, totalSpace / mColumnWidth);
setSpanCount(spanCount);
mColumnWidthChanged = false;
}
super.onLayoutChildren(recycler, state);
}
}
但是应用程序因以下错误而崩溃：
RecyclerView正在计算布局或滚动时无法调用此方法
(链接到line => setSpanCount(spanCount) );
有人可以帮助我进行此修改吗？
