在数组中获取/搜索

Question

如何获取int "icon"从Int值数组中取出一个示例:

2 = R.drawable.ic_blue?

或:如何获得:R.drawable.ic_blue?知道id: 2吗?

public class iconsList {
public class IntValues {
public int id;
public int icon;
public IntValues(int id, int icon){
this.id=id;
this.icon=icon;
}
}
IntValues[] icons = new IntValues[] {
new IntValues(0, R.drawable.ic_default),
new IntValues(1, R.drawable.ic_red),
new IntValues(2, R.drawable.ic_blue),
};
}

Answer 1

将此方法添加到您的iconsList类

public IntValues find(int num) {
for (int i = 0; i < icons.length; i++) {
if (num == icons[i].icon) {
return icons[i];
}
}
return null;
}

您可以返回索引(i)或带有id..的IntValues类
