拡張するカスタムビューにこのメソッドがありますFrameLayout：

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    int currentItem = vp.getCurrentItem();
    if (inDragPanelZone(currentItem, ev.getX(), ev.getY()) && ev.getAction() == MotionEvent.ACTION_DOWN) {      
        if (!shouldAllowPaging()) { 
            return true; 
        }
        vp.setPagingEnabled(true);
    }
    return super.dispatchTouchEvent(ev);
}

たまに - 次の例外が発生します。

私も使用onInterceptTouchEvent()してみましたが、同じ例外が発生しました。

2.1 (Eclair) には、ポインター インデックスがチェックされず、-1 になるバグがあります。ViewPager を拡張するカスタム ビューを作成し、onTouchEvent をオーバーライドして、super.onTouchEvent への呼び出しを try/catch にラップすることができます。あまりきれいな修正ではありませんが、副作用（タッチイベントの失敗など）がないことを覚えています。

上記の回答に追加する また、 onInterceptTouchEvent メソッドのオーバーライドを試して、スーパー.onInterceptTouchEvent(ev)をtry and catchで囲み、ViewPagerで私のために働いたことができます

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
    try {
        return super.onInterceptTouchEvent(ev);
    } catch (IllegalArgumentException ex) {
        ex.printStackTrace();
    }
    return false;
}

同じ問題があり、例外をキャッチするカスタム ViewPager を作成しました。の解決策は次のkotlinとおりです。

class CustomViewPager : ViewPager {

    constructor(context: Context) : super(context)

    constructor(context: Context, attrs: AttributeSet?) : super(context, attrs)

    override fun onInterceptTouchEvent(ev: MotionEvent?): Boolean =
        try {
            super.onInterceptTouchEvent(ev)
        } catch (e: IllegalArgumentException) {
            //uncomment if you really want to see these errors
            //e.printStackTrace();
            false
        }
}
