谷歌有他们的颜色 - 指南,那么如何随机收到颜色？有没有办法从表格中指定一个数字,并从表格的所有颜色中获得随机颜色？

例如getMatColor(100);:

编辑 - 结果:( 图标颜色)

每次重新打开我的android工作室项目左侧树的所有条目都会关闭.
如何避免/或打开它们而不是一个一个地打开？

我想在第10个数组之后输入一个新行.我的阵列从1-365填充(day[0]=1, day[1]=2, ..).

这是我的代码,我坚持创建if-condition:

int day[] = new int[365];

        for(int i=0; i<day.length; i++){
            day[i] = i+1;
            System.out.print(day[i]+" ");
            if((i % 10) == 0){
                System.out.println();
            }
        }

这应该是我的控制台输出:

1 2 3 4 5 6 7 8 9 10 
11 12 13 14 15 16 17 18 19 20 
21 22 23 24 25 26 27 28 29 30 
31 32 33 34 35 36 37 38 39 40 
41 42 43 44 45 46 47 48 49 …

如何将这两个函数添加到android studio,将现有(不可访问)变量转换为私有/公共？截图是伪造的而不是真实的,但这是我的问题的目的.

要将局部变量转换为私有/公共,我必须执行以下步骤:
- 剪切[variable-class] [variable-name]
- 写入[private/public]
- 将光标位置更改为类头
- 粘贴[variable-class] [variable-name]
- 复制[variable-name]
- 将光标位置更改为类方法
- 粘贴[variable-name]

Android Studio中的向量xml：

<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"
android:viewportHeight="24.0"
android:viewportWidth="24.0">
<path
    android:fillColor="#FF000000"
    android:pathData="M12,15C7.58,15 4,16.79 4,19V21H20V19C20,16.79 16.42,15 12,15M8,9A4,4 0,0 0,12 13A4,4 0,0 0,16 9M11.5,2C11.2,2 11,2.21 11,2.5V5.5H10V3C10,3 7.75,3.86 7.75,6.75C7.75,6.75 7,6.89 7,8H17C16.95,6.89 16.25,6.75 16.25,6.75C16.25,3.86 14,3 14,3V5.5H13V2.5C13,2.21 12.81,2 12.5,2H11.5Z" />

结果：

更改24dp为96dp，结果：

Android Studio中的菜单xml：

...
<!-- Sperren -->
<TextView
    android:id="@+id/suppress_button"
    style="@style/TextAppearance.MaterialSheetFab.Sheet.Item"
    android:drawableLeft="@drawable/ic_assignment_return"
    android:drawableStart="@drawable/ic_assignment_return"
    android:text="Sperren" />

 <!-- IH-Auftrag -->
 <TextView
    android:id="@+id/setup_maintenance_order_button"
    style="@style/TextAppearance.MaterialSheetFab.Sheet.Item"
    android:drawableLeft="@drawable/ic_ih_auftraege"
    android:drawableStart="@drawable/ic_ih_auftraege"
    android:text="IH-Auftrag" />
    ...

所以我现在的问题是，如何像svg一样自动更改大小？
