interested in the question of how to divide the array into two rows in the final mapping? At the moment the array is displayed in one row.

final String[] mCitiesName ={"Π’Π°ΡΡŒΠΊΠ°", "Π Ρ‹ΠΆΠΈΠΊ", "ΠœΡƒΡ€Π·ΠΈΠΊ", "Π Ρ‹ΠΆΠΈΠΊ", "ΠœΡƒΡ€Π·ΠΈΠΊ", "Π Ρ‹ΠΆΠΈΠΊ", "ΠœΡƒΡ€Π·ΠΈΠΊ", "Π Ρ‹ΠΆΠΈΠΊ", "ΠœΡƒΡ€Π·ΠΈΠΊ", "Π Ρ‹ΠΆΠΈΠΊ", "ΠœΡƒΡ€Π·ΠΈΠΊ"};

For example, there is a menu, I threw an array into it, of course it displays 1 name in a column, you need to make 2 columns from this 1 column so that the menu does not scroll. An illustrative example, the image https://fastpic.co/image/hPZHnr , where Button is an array, I would like to see an array in about this format

  • What does "two rows in the final display" mean? Write the approximate result you want to get. - Bakhuss

  • @InnaAhtina Now it is clear that your rows are our speakers. OK. Now I’ll clarify what your menu means (List, Action, Popup ...). It is better if you give a link to the material that you are studying. By the way, two columns are already a table. [сities - cities, kitties - kitties] - oshatrk

You can create your own .xml layout and assign it using builder.setView() . In the layout, create two ListView that fill with the halves of the original array of names through adapters.

(Directly using builder.setItems() will not succeed, as this method creates its own ListView , and adds it to the layout itself).

You get this result:

Links: While installing Android Studio and Intel HAXM, managed to read an introduction to programming on Android ( lesson 1 , lesson 2 ) and about AlertList ( lesson 30 ), and google Android Custom Layout AlertDialog Example , Android Layout: width half of parent , Dynamically can I set onClickListener on ArrayAdapter? .

And this is not JavaFX at all ...

  • Thank you, everything works fine and everything is perfectly explained! - Inna Ahtina

maybe the TC meant type it

 Π’Π°ΡΡŒΠΊΠ° Π Ρ‹ΠΆΠΈΠΊ ΠœΡƒΡ€Π·ΠΈΠΊ Π Ρ‹ΠΆΠΈΠΊ ΠœΡƒΡ€Π·ΠΈΠΊ Π Ρ‹ΠΆΠΈΠΊ ΠœΡƒΡ€Π·ΠΈΠΊ Π Ρ‹ΠΆΠΈΠΊ ΠœΡƒΡ€Π·ΠΈΠΊ Π Ρ‹ΠΆΠΈΠΊ ΠœΡƒΡ€Π·ΠΈΠΊ null

If so, then one of the solutions might be:

 final String[] mCitiesName = {"Π’Π°ΡΡŒΠΊΠ°", "Π Ρ‹ΠΆΠΈΠΊ", "ΠœΡƒΡ€Π·ΠΈΠΊ", "Π Ρ‹ΠΆΠΈΠΊ", "ΠœΡƒΡ€Π·ΠΈΠΊ", "Π Ρ‹ΠΆΠΈΠΊ", "ΠœΡƒΡ€Π·ΠΈΠΊ", "Π Ρ‹ΠΆΠΈΠΊ", "ΠœΡƒΡ€Π·ΠΈΠΊ", "Π Ρ‹ΠΆΠΈΠΊ", "ΠœΡƒΡ€Π·ΠΈΠΊ"}; int count = mCitiesName.length; int m = (int) Math.round(count / 2d); String[][] mCName = new String[2][m]; int k = 0; for (int i = 0; i < mCitiesName.length; i++) { if (i < m) { mCName[0][i] = mCitiesName[i]; } else { mCName[1][k++] = mCitiesName[i]; } } for (int i = 0; i < mCName.length; i++) { for (int j = 0; j < mCName[i].length; j++) { System.out.print(mCName[i][j] +" "); } System.out.println(); }
