选定设备上的Android Gallery网格不工作

我已经在这里找到了一个代码，但是现在我还有一个问题。 正如您在main activity中看到的，gridview中显示的图像有一个onItemClick事件，但问题是单击图片时没有发生任何事情

主要活动

package com.javatechig.gridview;

import java.io.File;
import java.util.ArrayList;

import android.app.Activity;
import android.content.res.TypedArray;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;

import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.GridView;
import android.widget.Toast;

/**

public class MainActivity extends Activity {
    private GridView gridView;
    private GridViewAdapter customGridAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_delta);

        gridView = (GridView) findViewById(R.id.gridView);
        customGridAdapter = new GridViewAdapter(this, R.layout.row_grid, getData());
        gridView.setColumnWidth(400);
        gridView.setPadding(8, 8, 8, 8);
        gridView.setAdapter(customGridAdapter);

        gridView.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View v,
                    int position, long id) {
                Toast.makeText(MainActivity.this, position + "#Selected",
                        Toast.LENGTH_SHORT).show();
                Log.w("click", "click");
            }

        }); 



    }





    private ArrayList<ImageItem> getData() {
        final ArrayList imageItems = new ArrayList();

        String stringpath = Environment.getExternalStorageDirectory().toString()+"/Pictures/Hello Camera";
        File path=new File(stringpath);
        File[] imageFiles = path.listFiles();
        for (int i = 0; i < imageFiles.length; i++) {
          //  Bitmap bitmap = BitmapFactory.decodeFile(imageFiles[i].getAbsolutePath());
          //  imageItems.add(new ImageItem(bitmap, "Image#" + i));

            final BitmapFactory.Options options = new BitmapFactory.Options();
            options.inSampleSize = 4;

            Bitmap bitmap = BitmapFactory.decodeFile(imageFiles[i].getAbsolutePath(),options);
            imageItems.add(new ImageItem(bitmap, "Image#" + i));

        }

        return imageItems;}

}

我怎样才能修好它

谢谢

请从行网格线性布局中删除android:clickable属性。 这是在GridView获取事件之前捕获事件。 因此，只需将所有onClick和onLongClick绑定到GridView的onItemClick和onItemLongClick侦听器。

祝你好运。

我在这里或给定链接中都看不到任何onItemClick EventListener。@Burn是的，很抱歉我忘了添加该部分。我编辑了这个问题。主要的源代码在那里，添加了适配器和xml文件
