问题描述：在ViewPager的子VIew中，嵌套使用SwipeRefreshLayout，发现SwipeRefreshLayout的下拉功能时而就不能使用。原因：

down vote It is because there is a bug in SwipeRefreshLayout! The bug is “onRefresh doesn’t work PRoperly if the onMeasure is not called” !

由于在SwipeRefreshLayout 没有调用onMeasure 之前， onRefresh 不能正常工作。

public class SwipeRefreshLoading extends SwipeRefreshLayout { public SwipeRefreshLoading(Context context) { super(context, null); } public SwipeRefreshLoading(Context context, AttributeSet attrs) { super(context, attrs); } private boolean mMeasured = false; private boolean mPreMeasureRefreshing = false; @Override public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); if (!mMeasured) { mMeasured = true; setRefreshing(mPreMeasureRefreshing); } } @Override public void setRefreshing(boolean refreshing) { if (mMeasured) { super.setRefreshing(refreshing); } else { mPreMeasureRefreshing = refreshing; } }}
