Question

我想在片段内的网格视图中显示的图像上发生onclick事件时获取图像属性。我试图从传递给onItemClick方法的参数中获取值。当我尝试访问任何参数时，应用程序停止工作。

在烤面包机内部，我用v.getId（）/ position / id替换文本“test”。然后应用停止。

这是代码。

    GridView gridView = (GridView) view.findViewById(R.id.imageGrid);
    gridView.setAdapter(new ImageAdapter(this));    
    gridView.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
         Toast.makeText(getActivity(), "test"  ,Toast.LENGTH_SHORT).show();
        }});

我是否需要提供任何其他详细信息？或者我犯了什么愚蠢的错误？

更新：我在这里添加我的错误日志。

Answer 1

如果您将v.getId()/position/id传递给Toast，它会认为它代表来自id的{{1}}资源的String，它将找不到抛出那个例外。试试这个：

strings.xml

或

Toast.makeText(getActivity(), String.valueOf(position), Toast.LENGTH_SHORT).show();

GridView上的OnItemClickListener在片段内没有响应
