java.lang.IllegalArgumentException：pointerIndex超出范围异常 - dispatchTouchEvent

标签： android android-view

我在自定义视图中使用此方法扩展了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);
}

有一段时间 - 我得到以下例外：

我也尝试使用onInterceptTouchEvent()并获得相同的例外。

这是一个额外的堆栈跟踪：

3 个答案:

答案 0 :(得分：34)

2.1（Eclair）中存在一个错误，其中未检查指针索引，有时为-1。您可以创建一个扩展ViewPager的自定义视图，覆盖onTouchEvent并将调用包装在try / catch中的super.onTouchEvent中。虽然不是一个非常漂亮的修复，我记得它没有副作用（如错过触摸事件）。

答案 1 :(得分：10)

添加到上面的答案另外你可以尝试覆盖onInterceptTouchEvent方法和环绕super.onInterceptTouchEvent（ev）with try和catch在ViewPager中为我工作

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

答案 2 :(得分：1)

我遇到了同样的问题，并创建了一个自定义ViewPager来捕获异常。这是kotlin中的解决方案：

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
    }

}
