Answer 1

只需要对代码进行必要的更改

1. 你必须添加im.setOnClickListener(this); 在forView循环中。

2. 删除下面的方法

    im.setOnClickListener(new OnClickListener() { public void onClick(View v) { ImageView iv=(ImageView) v; Log.e("sfas","-->"+iv.getId()); } }); 

3. 覆盖onClick（）您已经在Activity中实现了onClickcListener 。

看下面的代码，（并与你的代码匹配，以了解实际问题）

            }
        });

Answer 2

您可以在创建视图时setId() ，然后是他的ID。 http://developer.android.com/reference/android/view/View.html#setId(int）

Answer 3

您正在使用im.setId(i);设置ImageView的ID im.setId(i); 。 因此ID将是i的值。 你可以在某处跟踪这个。
