更改工具栏溢出图标颜色

Question

我的android.support.v7.widgetAndroid应用中有一个工具栏.它的背景颜色是亮橙色,最好看的颜色是白色而不是黑色.

我的默认颜色是黑色而不是白色.由于它会与其他东西冲突,这几乎是不可能的.我无法将主要文本颜色更改为白色!

我设法改变了标题颜色. 我现在正在寻找的是如何改变动作按钮颜色(白色).

我的代码:

主要活动:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".UI.activities.MainActivity">

<android.support.v7.widget.Toolbar
    android:id="@+id/r2_toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:elevation="4dp"
    app:titleTextColor="@color/primary_text_material_light"
    app:subtitleTextColor="@color/primary_text_material_light"
    android:theme="@style/R2Theme.Toolbar"/>

<fragment android:name="com.r2retail.r2retailapp.UI.fragments.SetupFragment"
    android:layout_below="@+id/r2_toolbar"
    android:id="@+id/list"
    android:layout_weight="1"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />


</RelativeLayout>

菜单栏:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">

<item android:id="@+id/about"
    android:icon="@drawable/ic_menu"
    android:title="About"
    app:showAsAction="never"/>

</menu>

样式:

<resources>

<style name="R2Theme" parent="Theme.AppCompat.Light.NoActionBar">=
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorPrimary</item>
    <item name="android:textColorPrimary">@color/secondary_text_material_dark</item>
    <item name="android:textColorSecondaryInverse">@color/primary_text_material_light</item>
</style>

<style name="R2Theme.Toolbar" parent="R2Theme">
    <item name="actionMenuTextColor">@color/primary_text_material_light</item>
</style>

</resources>

Answer 1

风格:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    ...
    <item name="actionOverflowButtonStyle">@style/MyOverflowButtonStyle</item>
</style>

<style name="MyOverflowButtonStyle" parent="Widget.AppCompat.ActionButton.Overflow">
    <item name="android:tint">#62ff00</item>
</style>

结果:

Answer 2

解决方案是更换图标本身。

第一

转到值/样式并在您的styles.xml文件中添加：

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
</style>

<style name="MyActionButtonOverflow" parent="android:style/Widget.Holo.Light.ActionButton.Overflow">
    <!--Here you need to put name of drawable you will create during the next step-->
    <item name="android:src">@drawable/your_white_icon</item> 
</style>

第二

然后转到可绘制文件夹。鼠标右键单击 -> 新建 -> 矢量资产。然后按图标图像并从名为ic_more_vert_black_24dp 的建议图标中进行选择。

自定义 -> 按下一步 -> 完成。

然后打开新创建的图标文件。代码看起来像这样。

<vector xmlns:android="http://schemas.android.com/apk/res/android"
        android:width="24dp"
        android:height="24dp"
        android:viewportWidth="24.0"
        android:viewportHeight="24.0">
    <path
        android:fillColor="#FFFFFFFF" <!-- Here u can change color-->
        android:pathData="M12,8c1.1,0 2,-0.9 2,-2s-0.9,-2 -2,-2 -2,0.9 -2,2 0.9,2 2,2zM12,10c-1.1,0 -2,0.9 -2,2s0.9,2 2,2 2,-0.9 2,-2 -0.9,-2 -2,-2zM12,16c-1.1,0 -2,0.9 -2,2s0.9,2 2,2 2,-0.9 2,-2 -0.9,-2 -2,-2z"/>
</vector>

fillColor将属性更改为您需要的颜色。将此文件放入第一步中描述的样式。

瞧！我们三个点的颜色不会根据基本应用程序样式而改变（#FF2012 颜色的结果）。

另一种方法是用代码而不是 XML：

public static boolean colorizeToolbarOverflowButton(@NonNull Toolbar toolbar, @ColorInt int color) {
    final Drawable overflowIcon = toolbar.getOverflowIcon();
    if (overflowIcon == null)
        return false;
    toolbar.setOverflowIcon(getTintedDrawable(toolbar.getContext(), overflowIcon, toolbarIconsColor));
    return true;
}

public static Drawable getTintedDrawable(@NonNull Context context, @NonNull Drawable inputDrawable, @ColorInt int color) {
    Drawable wrapDrawable = DrawableCompat.wrap(inputDrawable);
    DrawableCompat.setTint(wrapDrawable, color);
    DrawableCompat.setTintMode(wrapDrawable, Mode.SRC_IN);
    return wrapDrawable;
}

如果成功为溢出图标着色，该函数将返回 true。

如果您不想使用有色可绘制对象，还有另一种选择：

public static boolean colorizeToolbarOverflowButton(@NonNull Toolbar toolbar, @ColorInt Integer color) {
    final Drawable overflowIcon = toolbar.getOverflowIcon();
    if (overflowIcon == null)
        return false;
    final PorterDuffColorFilter colorFilter = toolbarIconsColor == null ? null : new PorterDuffColorFilter(toolbarIconsColor, PorterDuff.Mode.MULTIPLY);
    overflowIcon.setColorFilter(colorFilter);
    return true;
}

此外，如果您希望对操作项和导航项的图标进行着色，您可以尝试此操作（基于此处）：

/**
 * Use this method to colorize toolbar icons to the desired target color
 *
 * @param toolbarView       toolbar view being colored
 * @param toolbarIconsColor the target color of toolbar icons
 */
@JvmStatic
@UiThread
fun colorizeToolbarActionItemsAndNavButton(toolbarView: Toolbar, @ColorInt toolbarIconsColor: Int?) {
    //https://snow.dog/blog/how-to-dynamicaly-change-android-toolbar-icons-color/
    val colorFilter = if (toolbarIconsColor == null) null else PorterDuffColorFilter(toolbarIconsColor, Mode.MULTIPLY)
    for (i in 0 until toolbarView.childCount) {
        val v = toolbarView.getChildAt(i)
        //Step 1 : Changing the color of back button (or open drawer button).
        if (v is ImageButton) {
            //Action Bar back button
            v.drawable.mutate().colorFilter = colorFilter
        }
        if (v is ActionMenuView) {
            for (j in 0 until v.childCount) {
                //Step 2: Changing the color of any ActionMenuViews - icons that
                //are not back button, nor text, nor overflow menu icon.
                val innerView = v.getChildAt(j)
                if (innerView is ActionMenuItemView) {
                    val drawablesCount = innerView.compoundDrawables.size
                    for (k in 0 until drawablesCount) {
                        if (innerView.compoundDrawables[k] != null) {
                            innerView.post { innerView.compoundDrawables[k].mutate().colorFilter = colorFilter }
                        }
                    }
                }
            }
        }
    }
}

用法：

override fun onCreateOptionsMenu(menu: Menu): Boolean {
    menuInflater.inflate(R.menu.menu_main, menu)
    toolbar.doOnPreDraw {
        colorizeToolbarActionItemsAndNavButton(toolbar,0xffff0000.toInt())
    }
    return true
}
