Landscape Orientation: Change imageview src (using Picasso)

I am using a custom array adapter and displaying an image and some text within each row (JSON from a movie database API). When I change the orientation of the device, the list is loaded again and everything is displayed correctly, even though I have not specified a landscape orientation anywhere in the code. So far, great!

My problem is that in the landscape orientation I would like to only change the image that I am loading (using Picasso since it is an image URL). I want everything else to remain as is.

How can I achieve the same? Does Picasso itself have a function which could take care of such an issue?

Let me know if some code is needed. Thanks!

You should detect when your device change orientation
Then you should update the list datasource base on orientation and notifyDataSetChanged

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Checks the orientation of the screen
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        // change all image path in listdata to landscape path

        // for example
        // for (Item item : listData) {
        //     item.setDisplayImagePath(landscapePath);
        // } 
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
        // change all image path in listdata to portrait path
    }

    youListViewAdapter.notifyDataSetChanged(); 
}

Hope this help

You can try this piece of code: 

    Display display = ((WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
    int rotation = display.getRotation();
    if (rotation != 0) {
        Picasso.with(getApplicationContext()).load(your_url).into(your_imageview);
    }

It detects if there's a screen rotation, the display.getRotation returns an int (that equals 0 if there isn't any rotation), from there you can use Picasso to change your imageview.

Cheers,
