我正在使用recyclerview-mutiselect在我的应用程序中实现动作模式选择模式。

但是，覆盖 onDestroyActionMode 并添加行 getMultiSelector().clearSelections() 会导致 jni 崩溃。这是什么原因造成的？它可以修复吗？如果是怎么办？

    @Override
    public void onDestroyActionMode(ActionMode actionMode) {
        getMultiSelector().clearSelections();
        getMultiSelector().setSelectable(false);
    }

似乎该错误位于onDestroyActionMode. 持有人应该在MultiSelector变得不可选择之前被停用。此解决方法对我有用：

 @Override
public boolean onActionItemClicked(ActionMode actionMode, MenuItem menuItem) {
    if (menuItem.getItemId()==  R.id.action_delete){

        deleteItems(mMultiSelector.getSelectedPositions());

        // finish actionMode after you've handled selected positions
        // don't clear selections here - they will be cleared in onDestroyActionMode
        actionMode.finish();
        return true;
    }
    return false;
}

@Override
public void onDestroyActionMode(ActionMode actionMode) {
    // don't call super here - leads to crash!
    // clear selections
    mMultiSelector.clearSelections();
    // here we need to change the mIsSelectable property without refreshing all the holders,
    // so we cant use mMultiSelector.setSelectable(false)
    try {
        Field field = mMultiSelector.getClass().getDeclaredField("mIsSelectable");
        if (field != null) {
            if (!field.isAccessible())
                field.setAccessible(true);
            field.set(mMultiSelector, false);
        }
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (NoSuchFieldException e) {
        e.printStackTrace();
    }
}
