推荐答案
此答案写于2015年10月之前,当时FAB上的android:tint
仅受API> = 21支持.
This answer was written before October 2015, when android:tint
on FAB was supported only with API >= 21.
更新
请参阅@Saleem Khan的答案,这是使用以下方法设置色调的标准方法:
Refer to the answer of @Saleem Khan which is the standard way to set the tint using:
android:tint="@android:color/white"
通过FAB上的XML.
via XML on FAB.
OLD(2015年6月)
您可以使用ColorFilter以编程方式对其进行更改.
You can change it programmatically using ColorFilter.
//get the drawable
Drawable myFabSrc = getResources().getDrawable(android.R.drawable.ic_input_add);
//copy it in a new one
Drawable willBeWhite = myFabSrc.getConstantState().newDrawable();
//set the color filter, you can use also Mode.SRC_ATOP
willBeWhite.mutate().setColorFilter(Color.WHITE, PorterDuff.Mode.MULTIPLY);
//set it to your fab button initialized before
myFabName.setImageDrawable(willBeWhite);
