Thread: How i can create a ListView from a Selection

  1. #1

    Default How i can create a ListView from a Selection

    Hi, im trying to create a listview from a selection of a AutoCompleteTextView

    here's my code

    final AutoCompleteTextView editText = findViewById(R.id.actv);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, names);
    editText.setAdapter(adapter);

    editText.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

    // select ACTV (AutoCompleteTextView)
    String authorPicked = parent.getItemAtPosition(position).toString();
    final List<News> escritor = articlesProvider.getArticlesByAuthorName(authorPic ked);

    Toast toast = Toast.makeText(getApplicationContext(), authorPicked, Toast.LENGTH_SHORT);
    toast.show();

    ArrayList<String> articulos = new ArrayList<>();
    for(Article author : escritor) {
    frases.add(author.getArticle());

    }

    ListView myList;
    myList = findViewById(R.id.ListView1);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, articulos);
    myList.setAdapter(adapter);

    }
    });

    but with this i don't get results if i print the value of
    Log.d("Valor: ","Contiene " + escritor);
    i get [] as result
