Break line in json string java

Question

Don\'t know how to express myslef very well.As you see down in my code I have a String,an ArrayList of Strings and a spinner.

In my code I add the elements of my String

Answer 1

Modify your string which will be shown in spinner like this

StringBuffer accounts = new StringBuffer("one");
stringBuffer.append("\n");
stringBuffer.append("two");
stringBuffer.append("\n");
stringBuffer.append("three");
stringBuffer.append("\n");
stringBuffer.append("four");

TextView in the spinner will populate the values in different lines provided height and width is wrap_content

Answer 2

Try below code.

 ArrayList<String> spinnerAccounts = new ArrayList<>(); // I don't know the use of this ArrayList
 Spinner accounts = (Spinner)findViewById(R.id.accounts);
 ArrayAdapter<String> adapter =
       new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,spinnerAccounts);
 adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
 accounts.setAdapter(adapter);
 spinnerAccounts.add("one");
 spinnerAccounts.add("two");
 spinnerAccounts.add("three");
 spinnerAccounts.add("four");
 adapter.notifyDataSetChanged();

Add items you want to display in Spinner using spinnerAccounts.add("ACCOUNT_NAME") method.

Hope It'll help you.

Change u r code "accounts" used two times. Make arraylist for accounts and load into spinner.

    Spinner spinner1 = (Spinner) findViewById(R.id.spinner1);
    List<String> accountsList = new ArrayList<String>();
    accountsList.add("one");
    accountsList.add("two");
    accountsList.add("three");
    accountsList.add("four");

    ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>
                 (this,android.R.layout.simple_spinner_item,accountsList);

    dataAdapter.setDropDownViewResource
                 (android.R.layout.simple_spinner_dropdown_item);

    spinner1.setAdapter(dataAdapter);

    // Spinner item selection Listener  
    addListenerOnSpinnerItemSelection();

    // Button click Listener 
    addListenerOnButton();
