変更されたPullToRefreshライブラリに問題があります

https://github.com/johannilsson/android-pulltorefresh/pull/40

Androidバージョン2.xでは正常に動作しますが、4.xではクラッシュします（動作するかどうかを確認するための3.xデバイスがありません）。

4.xでは、次の方法で失敗します。

 private void applyHeaderPadding(MotionEvent ev) {
    // Workaround for getPointerCount() which is unavailable in 1.5
    // (it's always 1 in 1.5)
    int pointerCount = 1;
    try {
        Method method = MotionEvent.class.getMethod("getPointerCount");
        pointerCount = (Integer)method.invoke(ev);
    } catch (NoSuchMethodException e) {
        pointerCount = 1;
    } catch (IllegalArgumentException e) {
        throw e;
    } catch (IllegalAccessException e) {
        System.err.println("unexpected " + e);
    } catch (InvocationTargetException e) {
        System.err.println("unexpected " + e);
    }

    for (int p = 0; p < pointerCount; p++) {
        if (mRefreshState == RELEASE_TO_REFRESH) {
            if (isVerticalFadingEdgeEnabled()) {
                setVerticalScrollBarEnabled(false);
            }

            int historicalY = (int) ev.getHistoricalY(p);

            // Calculate the padding to apply, we divide by 1.7 to
            // simulate a more resistant effect during pull.
            int topPadding = (int) (((historicalY - mLastMotionY)
                    - mRefreshViewHeight) / 1.7);

            mRefreshView.setPadding(
                    mRefreshView.getPaddingLeft(),
                    topPadding,
                    mRefreshView.getPaddingRight(),
                    mRefreshView.getPaddingBottom());
        }
    }
}

クラッシュの行は次のとおりです。

int historicalY = (int) ev.getHistoricalY(p);

この問題を解決するにはどうすればよいですか？

よくわかりませんが、変更してみてください

int historicalY = (int) ev.getHistoricalY(p);

に

if(p>pointerCount)
{
int historicalY = (int) ev.getHistoricalY(p);
}

代わりに私のライブラリを試してみることをお勧めします：https ：//github.com/chrisbanes/Android-PullToRefresh
