Question

我准备了一个包含6张图片的GridView，当我点击它时，每张图片都必须启动一个Activity。如何在GridView中实现？非常感谢你。代码：

public class ImageAdapter extends BaseAdapter {
    private Context mContext;

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

    public int getCount() {
        return mThumbIds.length;
    }

    public Object getItem(int position) {
        return null;
    }

    public long getItemId(int position) {
        return 0;
    }

    // create a new ImageView for each item referenced by the Adapter
    public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imageView;
        if (convertView == null) {  // if it's not recycled, initialize some attributes
            imageView = new ImageView(mContext);
            imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setPadding(0, 0, 0, 0);
        } else {
            imageView = (ImageView) convertView;
        }

        imageView.setImageResource(mThumbIds[position]);
        return imageView;
    }

    // references to our images
    private Integer[] mThumbIds = {
            R.drawable.stock, R.drawable.rouge,
            R.drawable.stock, R.drawable.rouge,
            R.drawable.stock, R.drawable.rouge,
    };
}

您可以使用View#setOnClickListener(View.OnClickListener)

执行此操作

imageView.setOnCLickListener(new View.OnClickListener() {
    public void onClick(View v) {
        //start Activity here
    }
});

在GridView中编写元素时触发活动
