java - Spinner String 项目值获取(不是字符串名称)android

Question

我在 strings.xml 中使用

<string-array name="country_arrays">
    <item value="0">ValueName0</item>
    <item value="1">ValueName1</item>
    <item value="2">ValueName2</item>
    <item value="3">ValueName3</item>
    <item value="4">ValueName4</item>
</string-array>

我在 Java 代码中使用“获取选择选项值”

String.valueOf(option.getSelectedItem())

Toast.makeText(AvpMain.this,
                      "Loading Wait : " + "\n Search : "+ sbox1 + 
                      "\n("+ String.valueOf(option.getSelectedItem())+") Result",
                      Toast.LENGTH_SHORT).show();

如果用户选择 ValueName3，则结果显示 ValueName3 但我想显示值而不是值名称

例如。如果用户选择 ValueName2 那么结果显示:2

试试这个方法，希望能帮助您解决问题。

strings.xml

<array name="country_arrays">
    <item>ValueName0</item>
    <item>ValueName1</item>
    <item>ValueName2</item>
    <item>ValueName3</item>
    <item>ValueName4</item>
</array>

<array name="country_value_arrays">
    <item>0</item>
    <item>1</item>
    <item>2</item>
    <item>3</item>
    <item>4</item>
</array>

private ArrayList<String> countryList;
private ArrayList<String> countryValueList;

countryList = new ArrayList<String>(Arrays.asList(getResources().getStringArray(R.array.country_arrays)));
countryValueList = new ArrayList<String>(Arrays.asList(getResources().getStringArray(R.array.country_value_arrays)));

option.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                  Toast.makeText(AvpMain.this,"Loading Wait : " + "\n Search : "+ sbox1 + "\n("+countryValueList.get(position)+") Result",Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }
        });

或

Toast.makeText(AvpMain.this,"Loading Wait : " + "\n Search : "+ sbox1 + "\n("+option.getSelectedItem().toString().charAt(option.getSelectedItem().toString().length())+") Result",Toast.LENGTH_SHORT).show();
