Answer 1

我们在values/arrays.xml

中有一个数组

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <!-- ... -->

    <!-- Pager position (5 pages) -->
        <string-array name="positions" translatable="false">
            <item>\u25cf \u25cb \u25cb \u25cb \u25cb</item>
            <item>\u25cb \u25cf \u25cb \u25cb \u25cb</item>
            <item>\u25cb \u25cb \u25cf \u25cb \u25cb</item>
            <item>\u25cb \u25cb \u25cb \u25cf \u25cb</item>
            <item>\u25cb \u25cb \u25cb \u25cb \u25cf</item>
        </string-array>

    <!-- ... -->

</resources>

此处，<!-- ... -- >表示您可能有其他数组。

现在，如何在代码中设置此值？

// Declare the array (5 positions)
private static String positions[] = new String[5];
// Fill it by getting it from the resource array we prepared earlier
positions = getResources().getStringArray(R.array.positions);

// Prepare an index
private static int pIndex = 0;
//Set it's value in code (here it's fixed, but normally it's a counter)
// pInxex range: 0,..., 4
pIndex = 3;

// Find the position holder View
final TextView txtPosition = (TextView) v.findViewById(R.id.txtPosition);
// Set its value
txtPosition.setText(positions[pIndex]);

结果（pIndex = 3）
