以编程方式设置工具栏图标颜色

Question

如何设置的图标(家庭和溢出菜单图标)的颜色在Toolbar/ AppBarLayout 编程？

我想更改活动中单个片段的工具栏颜色方案.将AppBarLayout背景设置为浅色(例如浅灰色appBarLayout.setBackgroundResource(..);)会产生白色图标和白色标题,几乎看不到.

其布局如下:

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fitsSystemWindows="true">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:theme="@style/ToolbarStyle"
        app:layout_scrollFlags="scroll|enterAlways"/>

</android.support.design.widget.AppBarLayout>

支持23更改溢出图标很容易.这是Lorne Laliberte回答的方法

public static void setOverflowButtonColor(final Toolbar toolbar, final int color) {
    Drawable drawable = toolbar.getOverflowIcon();
    if(drawable != null) {
        drawable = DrawableCompat.wrap(drawable);
        DrawableCompat.setTint(drawable.mutate(), color);
        toolbar.setOverflowIcon(drawable);
    }
}

你可以改变你的家庭,通过你的自定义drawable ..

getSupportActionBar().setHomeAsUpIndicator(R.drawable.your_drawable)

或改变它的颜色

final Drawable upArrow = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
upArrow.setColorFilter(Color.parseColor("#FFFFFF"), PorterDuff.Mode.SRC_ATOP);
getSupportActionBar().setHomeAsUpIndicator(upArrow);

编辑: 如果你想更改更多的元素这里是改变所有工具栏图标颜色的好帖子.

希望这可以帮助!!

我接受了最有帮助的答案（并对此进行了评论），解释了我使用了其链接的代码片段的组合来形成单一AppBarLayout/ Toolbar着色方法。它涵盖了背景，标题，字幕，后退/抽屉图标和溢出图标的颜色，以及ImageButtons添加的任何自定义。这是我的结果（请原谅英语的“ colour”拼写（！）..）：

public static void colouriseToolbar(AppBarLayout appBarLayout, @ColorInt int background, @ColorInt int foreground) {
    if (appBarLayout == null) return;

    appBarLayout.setBackgroundColor(background);

    final Toolbar toolbar = (Toolbar)appBarLayout.getChildAt(0);
    if (toolbar == null) return;

    toolbar.setTitleTextColor(foreground);
    toolbar.setSubtitleTextColor(foreground);

    final PorterDuffColorFilter colorFilter
            = new PorterDuffColorFilter(foreground, PorterDuff.Mode.MULTIPLY);

    for (int i = 0; i < toolbar.getChildCount(); i++) {
        final View view = toolbar.getChildAt(i);

        //todo: cal icon?
        Log.d(Globals.TAG, "view: "+i+" "+view.getClass().toString());

        //Back button or drawer open button
        if (view instanceof ImageButton) {
            ((ImageButton)view).getDrawable().setColorFilter(colorFilter);
        }

        if (view instanceof ActionMenuView) {
            for (int j = 0; j < ((ActionMenuView) view).getChildCount(); j++) {

                final View innerView = ((ActionMenuView)view).getChildAt(j);

                //Any ActionMenuViews - icons that are not back button, text or overflow menu
                if (innerView instanceof ActionMenuItemView) {
                    Log.d(Globals.TAG, "view (actionmenuitemviwe): "+i);

                    final Drawable[] drawables = ((ActionMenuItemView)innerView).getCompoundDrawables();
                    for (int k = 0; k < drawables.length; k++) {

                        final Drawable drawable = drawables[k];
                        if (drawable != null) {
                            final int drawableIndex = k;
                            //Set the color filter in separate thread
                            //by adding it to the message queue - won't work otherwise
                            innerView.post(new Runnable() {
                                @Override
                                public void run() {
                                    ((ActionMenuItemView) innerView).getCompoundDrawables()[drawableIndex].setColorFilter(colorFilter);
                                }
                            });
                        }
                    }
                }
            }
        }
    }

    //Overflow icon
    Drawable overflowIcon = toolbar.getOverflowIcon();
    if (overflowIcon != null) {
        overflowIcon.setColorFilter(colorFilter);
        toolbar.setOverflowIcon(overflowIcon);
    }
}
