Trouble expanding image in samsung s8

As screen height of samsung s8 is quite large.My images in LoginUI(attached) were looking small.I calculated phone's height in dp programmatically.
DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
float dpHeight = displayMetrics.heightPixels / displayMetrics.density;
Log.d("checkheightdp",dpHeight+"");
It gave me dpheight 692.So,I create a separate layout-h692dp and put my layout with increased image height.For some reason,It is still picking the default layout and hence image not expanding.
My code:
public class LoginActivity extends AppCompatActivity {

Finally I got my answer,why creating a separate height layout was not working.
Though screen height of samsung s8 is 692 dp,but 25dp is not available as It is used by system UI.
Apparently it was stated in developer.android.com.
The Android system might use some of the screen for system UI (such as the system bar at the bottom of the screen or the status bar at the top), so some of the screen might not be available for your layout.
Therefore,subtracting 25 dp from 692 gives 667dp.Creating layout-h667dp worked.
I went to this post.

Try to tag the data model/ data source with your list view view.setTag(dataModel) in getView method of your adapter class.

Why not try RecyclerView instead of ListView and use Fresco Image Library?

Finally found a solution, the problem was with the android:launchMode in the manifest.

Please tell me where i have to add this code :
Bundle extras = getIntent().getExtras();
String response = extras.getString("FRIENDS");
Log.d(LOG_TAG, "onCreate()" + response);
try {
jsonArray = new JSONArray(response);
} catch (JSONException e) {
FacebookUtility.displayMessageBox(this, this.getString(R.string.json_failed));
}
and any other code need to move from FriendsList class to TabSample Class
