マテリアルデザインの色をランダムに受け取るにはどうすればよいですか？
Googleには 色-ガイドライン があるので、ランダムに色を受け取る方法は？テーブルから番号を指定し、テーブルのすべての色からランダムな色を受け取る方法はありますか？
例：getMatColor(100);：
編集-結果：（アイコンの色）
遅くならないよりはましだ。
実際の目的が色のtypeのランダムなマテリアルカラーを取得することである場合の私の新しい応答。

次のメソッドを追加して、親タイプからランダムな色を選択します
private int getMatColor(String typeColor)
{
int returnColor = Color.BLACK;
int arrayId = getResources().getIdentifier("mdcolor_" + typeColor, "array", getApplicationContext().getPackageName());
if (arrayId != 0)
{
TypedArray colors = getResources().obtainTypedArray(arrayId);
int index = (int) (Math.random() * colors.length());
returnColor = colors.getColor(index, Color.BLACK);
colors.recycle();
}
return returnColor;
}
使用方法
txt.setTextColor(getMatColor("500"));
古いSDKで動作するものが必要な場合は、次の方法を試すことができます。
TypedArray colors = getResources().obtainTypedArray(R.array.loading_colors);
int index = (int) (Math.random() * colors .length());
int color = colors.getColor(index, Color.BLACK);
textView.setTextColor(color);
colors.recycle();
あなたはarray.xmlであなたの色を宣言する必要があります：

ただし、リフレクションよりも効率が悪いことに注意してください。
リフレクションを使用すると、すべてのJava.awt.Color定数、名前付きの約148色を取得できます
_for (Field field : Color.class.getDeclaredFields()) {
int modifiers = field.getModifiers();
if (Modifier.isPublic(modifiers) && Modifier.isStatic(modifiers)
&& Modifier.isFinal(modifiers) && field.getType() == Color.class) {
String colorName = field.getName().toLowerCase(Locale.US);
Color color = Color.valueOf(colorName);
System.out.printf("- %s -> %s%n", colorName, color);
}
}
_これはリフレクションを使用し、定数名は人間が読める名前であると想定しています。
_[139] thistle -> 0xd8bfd8ff
[140] tomato -> 0xff6347ff
[141] turquoise -> 0x40e0d0ff
[142] Violet -> 0xee82eeff
[143] wheat -> 0xf5deb3ff
[144] white -> 0xffffffff
[145] whitesmoke -> 0xf5f5f5ff
[146] yellow -> 0xffff00ff
[147] yellowgreen -> 0x9acd32ff
_したがって、リストに色を追加し、random.nextInt(colors.size())を使用してランダムに色を選択します。
これが私が書いたクラスです。独自のマテリアルカラーパレットを作成するか、ランダムなカラーを取得できます。

// get a random color.
int randomColor = MaterialColorPalette.getRandomColor("100");
// create your own material color palette
MaterialColorPalette myCustomPalette = new MaterialColorPalette(Color.CYAN);
int my200Color = myCustomPalette.getColor("200");
