I am creating an application that will need to store the specialties of each clinic registered in the application, these specialties later I will be in the database of Firebase, I am using a dialog with checkboxes where will show the specialties of the clinic, I am also using an array of strings that has a reference to an array defined in the.xml string with the specialties, and an Arraylist that saves the results, which items from the list of specialties have been selected, but I cannot convert the selected items into a list with the name of the specialties that were selected.
In the setPositiveButton method, there is an example that I can pass the specialties only to a common string.
private boolean[] especialidadesChecadas;
private String[] listaEspecialidades;
private ArrayList<Integer> mEspecialidadeSelecionados = new ArrayList<>();
botaoEspecialidades.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(redeSelecionada != null){
AlertDialog.Builder mBuilder = new AlertDialog.Builder(CadastroActivity.this);
mBuilder.setTitle("Seleciona as especialidades:")
.setMultiChoiceItems(listaEspecialidades, especialidadesChecadas, new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int position, boolean isChecked) {
if(isChecked){
if(!mEspecialidadeSelecionados.contains(position)){
mEspecialidadeSelecionados.add(position);
}
} else if (mEspecialidadeSelecionados.contains(position)){
mEspecialidadeSelecionados.remove((Integer) position);
}
}
});
mBuilder.setCancelable(false);
mBuilder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String item = "";
for(int i= 0; i < mEspecialidadeSelecionados.size(); i++){
item = item + listaEspecialidades[mEspecialidadeSelecionados.get(i)];
if(i != mEspecialidadeSelecionados.size() -1){
item = item + ", ";
}
}
//DESSA FORMA CONSIGO VER TODAS AS ESPECIALIDADES NUMA UNICA STRING, MAS PRECISAVA
//DE UM ARRAY DE STRING PARA ARMAZENAR DO FIREBASE DATABASE PARA PUXAR POSTERIORMENTE
Toast.makeText(CadastroActivity.this, ""+item, Toast.LENGTH_SHORT).show();
}
});
mBuilder.setNegativeButton("Fechar", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
mBuilder.setNeutralButton("Limpar", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//Limpar selecionados
//Passa por todos os itens e deseleciona
for(int i = 0; i < especialidadesChecadas.length; i++){
especialidadesChecadas[i] = false;
mEspecialidadeSelecionados.clear();
}
}
});
AlertDialog mDialog = mBuilder.create();
mDialog.show();
If you need an array of strings, just create the array, something like
List<String> strings = new ArrayList<>();and makestrings.add(item)instead of theitem = item + ", ";. If you then need to build a string based on the array joining the various elements, just useString.join– Isac
I did the test, but when sending to the Firebase Database it creates only one position and puts all the items there, example: [0]: Immunology, Orthodontics, does not separate them into other positions. If I store this way I don’t think I’ll be able to consult for specialties afterwards, since everyone will be in the same position, right?

Add to a
ArrayListwith the methodaddputs each item in a new position. Now how it looks in Firebase depends on how you are updating the information there– Isac
Thanks, I got through a for that goes through all the items and add in List<String> specialties.
