【xml array】通过xml资源文件定义数组

<string-array name="sample_names">
<item>foo</item>
<item>bar</item>
<item>baz</item>
</string-array>

String[] names = getResources().getStringArray(R.array.sample_names);

<integer-array name="sample_ids">
<item>1</item>
<item>2</item>
<item>3</item>
</integer-array>

int[] ids = getResources().getStringArray(R.array.sample_ids);

<array name="sample_images">
<item>@drawable/title</item>
<item>@drawable/logo</item>
<item>@drawable/icon</item>
</array>

TypedArray images = getResources().obtainTypedArray(R.array.sample_images);
Drawable drawable = images.getDrawable(0);

<array name="sample_colors">
<item>#FFFF0000</item>
<item>#FF00FF00</item>
<item>#FF0000FF</item>
</array>

TypedArray colors = getResources().obtainTypedArray(R.array.sample_colors);
int color = colors.getColor(0,0);// 参数分别为下标和默认值
