我想改变导航抽屉的汉堡/箭头图标的颜色。我知道我可以在样式中更改它,但我想在java中动态更改它。有人知道怎么做吗?

使用 appcompat-v7:23.0.1 下一段代码为我工作:
int color = Color.parseColor("#FFEEEE00");
final PorterDuffColorFilter colorFilter = new PorterDuffColorFilter(color, PorterDuff.Mode.SRC_ATOP);
for (int i = 0; i < toolbar.getChildCount(); i++) {
final View v = toolbar.getChildAt(i);
if (v instanceof ImageButton) {
((ImageButton) v).setColorFilter(colorFilter);
}
}
在public boolean onCreateOptionsMenu(Menu menu)

您可以使用新setTint
类的DrawableCompat
(来自support v4 lib)
// Get the icon you want as a drawable
Drawable drawable = ResourcesCompat.getDrawable(getResources(), R.drawable.ic_menu, null);
// "Enable" tinting process
drawable = DrawableCompat.wrap(drawable);
// Tint it
DrawableCompat.setTint(drawable, Color.BLACK);
// Set it as action bar icon
actionBar.setHomeAsUpIndicator(drawable);
