java.lang.IllegalArgumentException異常：pointerIndex超出範圍例外的 - dispatchTouchEvent

我在一個延伸FrameLayout我的自定義視圖有這樣的方法：java.lang.IllegalArgumentException異常：pointerIndex超出範圍例外的 - dispatchTouchEvent

@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); 
}

在一段時間

一次 - 我得到以下異常：

我也使用onInterceptTouchEvent()嘗試，得到了相同的異常。

工作對我來說，我有時也面臨着同樣的問題。嘗試發送'ev'副本而不是原始的'MotionEvent'。在方法的開頭添加一些類似於'MotionEvent evCopy = MotionEvent.obtain（ev）'的東西，並調用'super.dispatchTouchEvent（evCopy）'。 – 2013-05-09 10:45:21

它是否完全爲您解決問題？ – 2013-05-09 10:49:39

我還沒試過。對我來說，當我擺脫ScrollView並因其他原因重新設計應用程序時，問題消失了。 – 2013-05-09 10:51:35

有一個在2.1（埃克萊爾）中的錯誤，其中指針索引不檢查和有時是-1。您可以創建一個擴展ViewPager的自定義視圖，重寫onTouchEvent並將try/catch中的調用包裝爲super.onTouchEvent。雖然不是一個非常漂亮的解決方案，但我記得它沒有副作用（如錯過的觸摸事件）。

我看到了這個錯誤，我已經用你之前所建議的解決辦法，但我試圖找到一種方法來妥善處理.. – 2013-05-13 10:49:32

任何更新本或更好的解決辦法？ – JPM 2013-10-11 21:12:40

最近有一個支持庫的更新，它可能修復了這個錯誤（因爲它們修復了ViewPager，而不是2.1中導致的錯誤）。沒有檢查出來。 – FunkTheMonk 2013-10-14 14:11:44

添加到上面的回答，你也可以嘗試重寫onInterceptTouchEvent方法，並用try和catch圍繞super.onInterceptTouchEvent（EV）在ViewPager

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

我應該怎麼做，如果它得到了內部super.onInterceptTouchEvent崩潰（ EV）？ – 2016-04-23 04:06:06
