Android GridView显示详细项目

Question

我有一个关于GridView的源代码。 但是，我很困惑为什么有些代码是错误的。 这些是代码。我在MainActivity中的OnClick方法上出错了。在这有人帮助我吗？感谢

public void onItemClick(AdapterView <? > AdapterView, View View, int Int, long Long) {

    AdapterView = ((ImageItem) imageItems.get(Int)).getTitle();
                toDetail(Int, AdapterView);

        }
    });

我希望每个项目在点击时显示详细的图像和文字。我也得到这样的代码但是当我点击“GingerBread”项目时，它会转到第一项（“Astro”）

 public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
        ImageItem item = (ImageItem) parent.getItemAtPosition(position);

            //Create intent
        Intent intent = new Intent(getApplicationContext(), DetailActivity.class);
     //  intent.putExtra("android.intent.extra.TEXT", Integer.parseInt(getIntent().getStringExtra("android.intent.extra.TEXT")));
      intent.putExtra("title", item.getTitle());
            //Start details activity
        startActivity(intent);
         overridePendingTransition(R.anim.home_detail_entry, R.anim.home_detail_exit);
       }
    });
