IllegalArgumentException:pointerIndex超出SwipeRefreshLayout的范围

Question

我一直在IllegalArgumentException: pointerIndex out of range崩溃中得到一些崩溃,我不明白发生了什么.它不仅限于一个Android构建或设备,它发生在各种设备上的5.0.1,4.4.4,4.4.2,4.0.4,2.3.6.以下是更多上下文的完整日志输出.

所以我的问题是导致此错误的原因以及减轻此问题的可接受方法是什么？

编辑:这是MotionEvent.java:1998的链接,它在上面的崩溃中被引用.

编辑:这是我的onDestroy看起来像:

@Override
public void onDestroy() {

    AppMsg.cancelAll();
    SuperCardToast.cancelAllSuperCardToasts();

    super.onDestroy();
}

特别BaseActivity.java:105是我打电话的地方super.onDestroy();.

Answer 1

我假设当触摸事件仍然发生时抛出异常(在Activity即将发生时流式传输到本机触摸onDestroy().可以通过捕获异常来缓解这种情况,以避免崩溃.活动即将被销毁如果它已进入此状态.

我不确定(没有经过测试),但你可以尝试防止任何事件传递给实现,如果捕获异常不适合你.

public class ComeUpWithBetterNameSwipeRefreshLayout extends SwipeRefreshLayout {

    private boolean mAcceptEvents;

    public ComeUpWithBetterNameSwipeRefreshLayout(Context context) {
        super(context);
    }

    public void setAcceptEvents(boolean mAcceptEvents) {
        this.mAcceptEvents = mAcceptEvents;
    }
    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        return mAcceptEvents? super.onInterceptTouchEvent(ev) : true;
    }

    public ComeUpWithBetterNameSwipeRefreshLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    @Override
    protected void onAttachedToWindow() {
        super.onAttachedToWindow();
        mAcceptEvents = true;
    }

    @Override
    protected void onDetachedFromWindow() {
        super.onDetachedFromWindow();
        mAcceptEvents = false;
    }
}

要么

@Override
public void onDestroy() {
    mSwipeRefreshLayout.setAcceptEvents(false);
    AppMsg.cancelAll();
    SuperCardToast.cancelAllSuperCardToasts();

    super.onDestroy();
}

拿2:

SwipeRefreshLayout尝试从无效指针索引中获取getY(),如果找不到则调用findPointerIndex(ev, activePointer)返回-1.防止使用小于0的无效指针调度触摸事件并且指针索引大于或等于该事件的指针计数可能会阻止对本机MotionEvent实现内的指针进行抛出IAE的验证.

 @Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
    if(ev.getAction() == MotionEvent.ACTION_CANCEL) {
        int pointerCount = MotionEventCompat.getPointerCount(ev);
        int index = MotionEventCompat.getActionIndex(ev);
        mActivePointerId = MotionEventCompat.getPointerId(ev, index);
        index = MotionEventCompat.findPointerIndex(ev,mActivePointerId);
        if (index > -1 && index < pointerCount) {
            super.onInterceptTouchEvent(ev);
        } else {
            return true;
        }
    }else if(ev.getAction() == MotionEventCompat.ACTION_POINTER_DOWN && super.onInterceptTouchEvent(ev)) {
        final int index = MotionEventCompat.getActionIndex(ev);
        mActivePointerId = MotionEventCompat.getPointerId(ev, index);
        return false;
    }else if(ev.getAction() == MotionEventCompat.ACTION_POINTER_UP && super.onInterceptTouchEvent(ev)){
        onSecondaryPointerUp(ev);
        return false;
    }else if(ev.getAction() == MotionEvent.ACTION_DOWN && super.onInterceptTouchEvent(ev)){
        mActivePointerId = MotionEventCompat.getPointerId(ev, 0);
        return false;
    }
    return super.onInterceptTouchEvent(ev);
}

private void onSecondaryPointerUp(MotionEvent ev) {
    final int pointerIndex = MotionEventCompat.getActionIndex(ev);
    final int pointerId = MotionEventCompat.getPointerId(ev, pointerIndex);
    if (pointerId == mActivePointerId) {
        final int newPointerIndex = pointerIndex == 0 ? 1 : 0;
        mActivePointerId = MotionEventCompat.getPointerId(ev, newPointerIndex);
    }
}

Answer 2

它已经在AOSP问题跟踪器上登录.

您可以通过子类化SwipeRefreshLayout并捕获异常来修复它,例如:

public class SwipeRefreshLayout extends android.support.v4.widget.SwipeRefreshLayout {
    public SwipeRefreshLayout(Context context) {
        super(context);
    }

    public SwipeRefreshLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        try {
            return super.onTouchEvent(ev);
        } catch (IllegalArgumentException e) {
            //Fix for support lib bug, happening when onDestroy() is 
            return true;
        }
    }
}
