我正在尝试使用此方法以编程方式创建ColorStateList:

I am trying to create a ColorStateList programatically using this:

ColorStateList stateList = new ColorStateList(states, colors);

但是我不确定这两个参数是什么.

But I am not sure what are the two parameters.

根据文档:

public ColorStateList (int[][] states, int[] colors)

已添加到API级别1

Added in API level 1

创建一个ColorStateList，该列表返回从状态到颜色的指定映射.

Creates a ColorStateList that returns the specified mapping from states to colors.

有人可以解释一下如何创建它吗?

Can somebody please explain me how to create this?

推荐答案

请参见 developer.android/reference/android/R.attr.html#state_above_anchor 以获得可用状态列表.

See developer.android/reference/android/R.attr.html#state_above_anchor for a list of available states.

如果您想为禁用，未聚焦，未选中状态等设置颜色，只需对这些状态取反:

If you want to set colors for disabled, unfocused, unchecked states etc. just negate the states:

int[][] states = new int[][] { new int[] { android.R.attr.state_enabled}, // enabled new int[] {-android.R.attr.state_enabled}, // disabled new int[] {-android.R.attr.state_checked}, // unchecked new int[] { android.R.attr.state_pressed} // pressed }; int[] colors = new int[] { Color.BLACK, Color.RED, Color.GREEN, Color.BLUE }; ColorStateList myList = new ColorStateList(states, colors);
