AndroidAnnotations：如何访问@ItemClick查看 [英] AndroidAnnotations: how to access View on @ItemClick

问题描述

我用AndroidAnnotations构建Android应用程序。但我不知道如何下重构这个使用 @ItemClick ，因为 @ItemClick 不接受查看参数。顺便说一句，我用查看来获得选择的GridView的标签。

I use AndroidAnnotations to build Android application. But I have no idea how to refactor this below to use @ItemClick because @ItemClick doesn't accept View parameter. By the way, I use View to get tag of selected gridview.

        gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                String url = (String) view.getTag();
                intents.put("image", url);

                DetailActivity_.launch(HomeActivity.this, view.findViewById(R.id.image), intents);
            }
        });

任何想法？

推荐答案

可惜你不能添加查看参数，但可以使用位置参数。这样做的问题是没有方法返回点击查看，所以你必须使用一些逻辑来获取查看从所有的孩子们。

Unfortunately you cannot add a View parameter, but you can use the position parameter. The problem with that there is no method to return the clicked View, so you have to use some logic to get the View from all the children.

@ViewById(R.id.gridViewId)
GridView gridView;

@ItemClick(R.id.gridViewId)
void itemClicked(int position) {
    int firstPosition = gridView.getFirstVisiblePosition();
    int lastPosition = gridView.getLastVisiblePosition();

    View clickedView;

    if ((position < firstPosition) || (position > lastPosition))
        clickedView = null;

    clickedView = gridView.getChildAt(position - firstPosition);
    // do sg with clicked view
}

不过，这其实不是因为你的code，无AA ......然而，在查看参数可以被支持的很快的。在此之前，我建议坚持使用旧的方式，如果你真的有与查看参数工作。

But this is actually not as clean as your code without AA... However, the View parameter may be supported soon. Until that, i suggest to stick with the old way if you really has to work with the View param.
