return i;
}
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
ImageView image = new ImageView(mContext);

Gallery galPicture = findViewById(R.id.galPicture);
galleryAdapter = new GalleryAdapter(MainActivity.this);
galPicture.setAdapter(galleryAdapter);
//相应的点击事件
galPicture.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Toast.makeText(MainActivity.this, "图片" + i, Toast.LENGTH_LONG).show();
}
});
}
}
