gridview显示图片的方法是什么

GridView显示图片的方法可以通过以下步骤实现：

在布局文件中添加GridView控件：

<GridView    android:id="@+id/gridview"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:numColumns="auto_fit"    android:columnWidth="100dp"    android:verticalSpacing="10dp"    android:horizontalSpacing="10dp"    android:stretchMode="columnWidth"    android:gravity="center"/>

创建一个适配器类来提供数据给GridView：

public class ImageAdapter extends BaseAdapter {    private Context mContext;    private int[] mImages;    public ImageAdapter(Context context, int[] images) {        mContext = context;        mImages = images;    }    @Override    public int getCount() {        return mImages.length;    }    @Override    public Object getItem(int position) {        return null;    }    @Override    public long getItemId(int position) {        return 0;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        ImageView imageView;        if (convertView == null) {            imageView = new ImageView(mContext);            imageView.setLayoutParams(new GridView.LayoutParams(100, 100));            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);        } else {            imageView = (ImageView) convertView;        }        imageView.setImageResource(mImages[position]);        return imageView;    }}

在Activity中设置适配器并将其与GridView关联起来：

GridView gridView = findViewById(R.id.gridview);int[] images = {R.drawable.image1, R.drawable.image2, R.drawable.image3}; // 图片资源数组ImageAdapter adapter = new ImageAdapter(this, images);gridView.setAdapter(adapter);

这样就可以在GridView中显示图片了。
