我从2days开始遇到一个问题。我有一个网格视图,我需要显示图像。当我点击网格项时,它必须转到下一个活动。我能够在gridview中显示图像但是事情就是当我点击那个项目它没有响应..(OnItemClickListener不工作)。我无法在我做错的地方追踪我的问题。
package com.logictreeit.mobilezop.fragments;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.GridView;
import com.logictreeit.mobilezop.adapters.PhotoAdapter;
import com.logictreeit.mobilezop.custom.Utils;
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..
package com.logictreeit.mobilezop.adapters;
import java.util.List;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.ImageView;
import com.logictreeit.mobilezop.R;
import com.logictreeit.mobilezop.models.Photo;
public class DupPhotoAdapter extends ArrayAdapter<Photo> {
private static final String TAG = "PhotoAdapter";
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。
如果你们知道的话。请你告诉我......
谢谢, 切塔尼亚

我认为你的ImageViews窃取了Focus,因为它们是可检查的。所以项目点击不会发生,因为你的ImageViews拦截它。
将这些属性添加到您的图像视图可能有所帮助,但可能会给您的检查带来麻烦。
android:focusable="false"
android:focusableInTouchMode="false"
列表视图中的可检查项目有点痛苦。但我认为你会找到相关的主题如何做到这一点。
这是一个看起来合适的教程,我承认我没有仔细研究它,但你可能想:

还要确保您的适配器为isEnabled
返回true@Override
public boolean isEnabled(int i) {
return true;
}
http://developer.android.com/reference/android/widget/BaseAdapter.html#isEnabled(int)
isEnabled(int position)如果指定的项目返回true position不是分隔符。
否则点击事件不会为您的项目抛出

希望这可以帮助某人, 在gridview中,如果添加按钮或设置&#34; android:clickable = true&#34;在其中的元素中,不会监听gridview的OnItemClickListener,而是可以创建带有图像的Image或TextView,并查看您没有设置clickable =&#34; true&#34;。现在,OnItemClickListener将监听TextView,这对我有用。
