自 2 天以来,我一直遇到一个问题。我有一个网格视图,我需要显示图像。当我单击网格项目时,它必须转到下一个活动。我能够在 gridview 中显示图像,但问题是什么时候我点击它没有响应的那个项目..(OnItemClickListener 不工作)。我无法追踪我做错的问题。
package com.logictreeit.mobilezop.fragments;

public class Dup_AlbumPhotosFragment extends Fragment implements
OnItemClickListener {
private static final String TAG = "AlbumPhotos Fragment";
private GridView gridView;
private Context mContext;
private PhotoAdapter photoAdapter;
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
Log.v(TAG, "on Activity Created ");
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public void onAttach(Activity activity) {
super.onAttach(activity);
this.mContext = activity;
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Log.v(TAG, "OnCreateView");
gridView = new GridView(mContext);
gridView.setNumColumns(GridView.AUTO_FIT);
gridView.setClickable(true);
gridView.setOnItemClickListener(this);
photoAdapter = new PhotoAdapter(mContext, -1,Utils.getALbumList().get(0).getPhotosList());
gridView.setAdapter(photoAdapter);
return gridView;
}
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Log.v(TAG, "on ItemClikced");
}
}
这是我的片段..

private Context context;
private List<Photo> photoList;
public DupPhotoAdapter(Context context, int textViewResourceId,
List<Photo> objects) {
super(context, textViewResourceId, objects);
this.context = context;
this.photoList = objects;
}
public int getCount() {
return photoList.size();
}
public View getView(int position, View convertView, ViewGroup parent) {
convertView = LayoutInflater.from(context).inflate(
R.layout.grid_item_image_layout, null);
ImageView imageView = (ImageView) convertView
.findViewById(R.id.grid_item_imageview);
final CheckBox checkBox = (CheckBox) convertView
.findViewById(R.id.grid_item_checkbox);
final Photo photo = photoList.get(position);
if (photo.isSelected()) {
checkBox.setChecked(true);
} else {
checkBox.setChecked(false);
}
imageView.setImageResource(Integer.parseInt(photo.getFileUrl()));
checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
if (isChecked) {
photo.setSelected(true);
} else {
photo.setSelected(false);
}
}
});
return convertView;
}
}
这是我的适配器。
如果你们知道。请告诉我...
谢谢,柴坦亚
