在json字符串java中断行 [英] Break line in json string java

问题描述

不知道如何很好地表达myslef。正如你在我的代码中看到的那样，我有一个String，一个字符串的ArrayList和一个微调器。

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我的代码我在我的ArrayList中添加了String的元素，然后在我的微调器中。一切都很好，除了一切都在一条线上的事实，我希望每一个元素（一，二，三，四）在一个新的行。

In my code I add the elements of my String in my ArrayList and then in my spinner. All good,except the fact that everything is on a single line,and I want each of the elements ("one,two,three,four") in a new line.

注意：我不知道String帐户包含的内容以及它中包含的值。

Note: I do not know what String accounts contain and how many values it has in it.

ArrayList<String> spinnerAccounts = new ArrayList<>();
String accounts = "one two three four";
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(System.lineSeparator());
                spinnerAccounts.add(accountID.toString());

推荐答案

更改两次使用的代码帐户。为帐户创建arraylist并加载到微调器中。

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();
