Question

我有一个gridView，它正在填充图像文本等，现在我只想让所有gridview可点击所以我试着制作它

gridView1.setOnItemClickListener(new OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> parent, View view,
                        int position, long id) {
                    Log.i("The clicked item is:"+position, null);

                }

            });

但是当我单击gridview而不是向我显示logcat中的位置时，网格视图不起作用，它会将其视为致命异常。

Answer 1

您无法在Log.i()中将null作为参数传递。传递两个有效的字符串参数。

类似于：Log.i("Clicked Position is : ", Integer.toString(position));

Answer 2

应该更多的是

Log.i(getClass().getSimpleName(), "The clicked item is at: " + position);

因此标签和消息不是混合的blob。

Android Gridview onclick Event正在提供致命异常
