我无法在GridView中看到图像

我创建了GridView

<GridView xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/gridview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:columnWidth="90dp"
        android:numColumns="auto_fit"
        android:verticalSpacing="5dp"
        android:horizontalSpacing="5dp"
        android:stretchMode="columnWidth"
        android:gravity="center"
        />

和Gallery类的java文件：

package rs.srecnaplaneta.www.srecnaplaneta;

import android.content.Context;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;


public class klasaGalerija extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(R.layout.tab3galerija, container, false);
    }

    public class ImageAdapter extends BaseAdapter{

        private Context context;

        public Integer[] images = {
                R.drawable.slika21,
                R.drawable.slika22,
                R.drawable.slika23,
                R.drawable.slika24,
                R.drawable.slika25,
                R.drawable.slika26,
                R.drawable.slika27,
                R.drawable.slika28,
                R.drawable.slika29
        };

        public ImageAdapter(Context c){
            context = c;
        }

        @Override
        public int getCount(){
            return images.length;
        }

        @Override
        public Object getItem(int i) {
            return images[i];
        }

        @Override
        public long getItemId(int i) {
            return 0;
        }

        @Override
        public View getView(int i, View view, ViewGroup viewGroup) {

            ImageView imageView = new ImageView(context);
            imageView.setImageResource(images[i]);
            imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
            imageView.setLayoutParams(new GridView.LayoutParams(240, 240));
            return imageView;
        }

        GridView gridView = (GridView)getActivity().findViewById(R.id.gridview);

        public void setGridView(GridView gridView) {
            gridView.setAdapter(new ImageAdapter(getContext()));
        }
    }
}

我无法在GridView中看到图像库...我想用它来做

gridView.setAdapter（new ImageAdapter（getContext（）））;

但是，因为我有一个TabbedActivity并且我在Fragment中工作，看起来它给了我创建选项

public void setGridView（GridView gridView）{gridView.setAdapter（new ImageAdapter（getContext（）））; }

或类似的东西 . 但是当我启动项目时，我看不到图像 . 有人可以帮忙吗？如何更改Adapter或GridView？
