我应该使用哪个android控件来获取android中的2 x 2可滚动网格？

Question

How can i have 2 by 2 scrollable Grid? Which control should i use?

I tried Grid-View and as Grid-View can not have fixed rows so should i use Table-Layout or Grid-Layout ? or use linear-Layout in Grid-View ?

I want image to be displayed without being scaled down or scaled up so i am using AUTO_FIT and i get three rows with the below code but i want only two rows and two columns

@Override public View getView(int position, View convertView, ViewGroup parent) 
{
    ImageView view;

    if (convertView == null) 
    {

        view = (ImageView) convertView;
        view = new ImageView(context);
        view.setAdjustViewBounds(true);
        view.setLayoutParams(new GridView.LayoutParams(GridView.AUTO_FIT, GridView. AUTO_FIT));

    }
    else
         view = (ImageView) convertView;

    String url = getItem(position);

    Picasso.with(context).load(url).error(R.mipmap.no_photo).fit().into(view);

    return view;
}

Below is the sample attached image

Answer 1

I would recommend you use a RecyclerView with a GridLayoutManager . This will allow you to specify the number of columns:

recyclerView.setLayoutManager(new GridLayoutManager(context, 2));

If you would like to set the row height so that two rows always match the height of your screen, you could set it inside onBindView() of your adapter. You can ascertain the relative row height by subtracting the screen height from the height of your Toolbar :

//Could calculate this in your `Activity` class and pass the value to your Adapter
public int getProprtionalRowHeight() {

    DisplayMetrics displaymetrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
    int height = displaymetrics.heightPixels;

    return ((height - toolbar.getHeight()) / 2);

}

In your adapter:

@Override
public void onBindViewHolder(ItemViewHolder holder, int position) {

    //...

        ViewGroup.LayoutParams params = holder.itemView.getLayoutParams();
        params.height = valueReturnedFromGetProprtionalRowHeight;
        holder.itemView.setLayoutParams(params);

    }

you can use StaggeredGrid for this purpose its stable and easy to use. you can also use StaggeredGridLayoutManager with recycler view.
