推荐答案

如前所述，反射似乎是这个问题的关键.StringBuilder 和额外的格式不是必需的，添加它只是为了说明用法.

As suggested earlier, reflection seems to be the key to this question. The StringBuilder and extra formatting is not required, it was added only to illustrate usage.

import java.lang.reflect.Field;
...

StringBuilder builder = new StringBuilder();
builder.append("android : ").append(Build.VERSION.RELEASE);

Field[] fields = Build.VERSION_CODES.class.getFields();
for (Field field : fields) {
    String fieldName = field.getName();
    int fieldValue = -1;

    try {
        fieldValue = field.getInt(new Object());
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (NullPointerException e) {
        e.printStackTrace();
    }

    if (fieldValue == Build.VERSION.SDK_INT) {
        builder.append(" : ").append(fieldName).append(" : ");
        builder.append("sdk=").append(fieldValue);
    }
}

Log.d(LOG_TAG, "OS: " + builder.toString());

在我的 4.1 模拟器上，我得到以下输出:

On my 4.1 emulator, I get this output:

D/MainActivity( 1551): OS: android : 4.1.1 : JELLY_BEAN : sdk=16
