Question

今天我得到两个数组的结果，这是不可取的结果。例如，我有这样的数据：

<string-array name="player">
<item>CR7</item>
<item>Sergio Ramos</item>
<item>Ozil</item>
</string-array>

<string-array name="posisi">
<item>Stricker</item>
<item>Defender</item>
<item>Winger</item>
</string-array>

，当我尝试使用循环数组获取数据时，结果如下所示： undesirable result

我希望我可以获取数据并像这样显示它们： Desirable result

您可以解决此问题吗？

Answer 1

您在'DoaPagi.java'中的getData方法不正确。您的“ for（）”循环嵌套。应这样声明：

for (int i = 0; i < data.length; i++) {
    list.add(new ModelDoa(data[i], baca[i], ModelDoa.DOA_PAGI));
}
